The most common reason for this is that the user has hit the "stop" button
in the browser before the page has been fully loaded.  The AJP13 protocol
(currently) doesn't support out-of-band messages to notify Tomcat of this
fact, so mod_jk(2) simply drops the connection to Tomcat instead.

Re: Release of memory

If you search http://nagoya.apache.org/bugzilla/buglist.cgi?product=fop you
will find several reports of memory leaks using fop.  Your best bet is to
take it up on the fop-users list.

Hi, I have a servlet that is generating reports on demand from a client
program. I'm using tomcat as servlet container, xml and xsl to generate
fo and fop to give me pdf. The reports tend to be big and memory is
being exhausted.

Can anyone tell me how to make tomcat release memory after a servlet is
finished? Now tomcat simply hold it and sooner or later my server starts
to swap processes because of it. It does so even if I force GC at the
end of the servlet. If it is left idle, it frees some over time, but it
takes to long.

Please help!

Re: Tomcat 5 and CATALINA_BASE/shared/lib problem...


Bug reported here:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=15774

Can someone please explain why the behavior is different and/or confirm 
that it is a real bug in Tomcat5?

Thanks,

Just a little follow-up to what I said below.  I had surmised that maybe 
CATALINA_HOME/shared/lib libraries where simply getting loaded first and 
maybe CATALINA_BASE/shared/lib libraries that had the same packages 
wouldn't be loaded because they would only be loaded once by 
Tomcat.  Well, this is false.  CATALINA_BASE/shared/lib is entirely 
ignored and libraries from CATALINA_HOME/shared/lib are always loaded even 
if CATALINA_BASE is set to a value different from CATALINA_HOME.

This is either a bug in Tomcat5 or a conscious decision was made to change 
the behavior or Tomcat5 -vs- Tomcat-4.1.x (and probably also Tomcat-4.0.x).

Can anyone confirm this?  Should I report this as a bug in Bugzilla?

Hi all,

Using Tomcat-4.1.x, I can have separate instances of Tomcat running which 
access their own shared/lib folder.  In Tomcat-5.0 latest nightly build, 
that doesn't seem to be the case.

For instance, using Tomcat-4.1.18, if I have some jars in 
CATALINA_HOME/shared/lib and I start up a new tomcat instance with 
CATALINA_BASE set as something other than CATALINA_HOME, the jars in 
CATALINA_HOME/shared/lib will *not* be loaded.  Instead, jars will be 
loaded from CATALINA_BASE/shared/lib (if it exists).  This is the 
behavior I expect and love!

However, using Tomcat-5.0, if I set things up the same way, jars in 
CATALNIA_HOME/shared/lib *will* be loaded and jars in 
CATALNIA_BASE/shared/lib are completely ignoredor it could be that it 
is picking up both of them, but loading jars in CATALINA_HOME/shared/lib 
first and then looking in CATALINA_BASE/shared/lib.  If a jar in the 
latter contains the same packages that were already loaded in the former, 
then the latter is ignored.  Either way, Tomcat-4.1.x completely ignores 
CATALINA_HOME/shared/lib if CATALINA_BASE is set and is different from 
CATALINA_HOME where Tomcat-5 loads CATALINA_HOME/shared/lib jars no 
matter what.  This is behavior that I don't expect and don't like.

I used the ability to separate instances to run apps which required 
different versions of xerces.  I put xerces-1.4.4.jar in 
CATALINA_HOME/shared/lib for apps which I use most often.  However, I 
have other apps that need either slightly modified version of 
xerces-1.4.4 or require xerces-2.x.x.  For those cases, I run a separate 
instance of Tomcat using a custom set CATALNIA_BASE with a local 
shared/lib with the appropriately versioned jars that I need for this 
particular app.

So, this is a great feature in Tomcat-4.1.x (and, I imagine, 
Tomcat-4.0.x) but it seems to be broken in Tomcat-5.0.  Is this new 
behavior in Tomcat-5.0 a bug or was it intentional?  If it was 
intentional, can someone explain the reasons for the change in behavior 
to that of Tomcat-4.1.x?

Re: how to get meaningful exception in JSP error page

As it happens, JasperException (at least in 4.1 Jasper2) subclasses
ServletException.  You should be able to get this by casting to a
ServletException and calling getRootCause().

Re: Connector Problem, has anyone seen this behavior?

The mod_jk (V1.0) for 3.2.x doesn't have the re-try connection logic that
the later versions have.  You should upgrade to at least V1.1 (ships with TC
3.3), or, better 1.2.x (current stable release).

Re: Parse error in application web.xml


Tomcat-3.3.x and above completely ignore the system classpath as far as 
webapps are concerned.  All jar files that you want your webapps to see 
will have to be in either the WEB-INF/lib of your webapp or in the 
designated library directories.  The only exception to this are the Java 
runtime classes and jars that you put in JAVA_HOME/jre/lib/endorsed or 
jre/lib/ext which, essentially, make those jars part of the Java 
runtime.  However, I don't recommend using those techniques for webapps 
unless you want to spend lots of time trying to debug classloader issues

Fire up tomcat with this flag

-Djava.endorsed.dirs=$CATALINA_HOME/common/endorsed

(make sure to put the new JAR files in that directory).. check out

http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-
howto.html and scroll down to the section XML Parsers and JDK 1.4
towards the bottom.

reference to external error-page

2003-01-02 Thread Michael Mendelson


Hello all,

I would like to use an error page for certain apache/httpd errors as well as
tomcat errors (e.g. 404). In the web.xml file though, the directive...


   
404
/error/404.html
   


...routes me to http://localhost/projectname/error/404.html.

How would I route to an error page location that might be on the same server,
but external to the project?

I'm using Apache 1.3.23 and Tomcat 4.1.18 (and mod_jk to route requests to
tomcat), if it matters.

Thanks,

Michael

Hi there,

I was reading an unrelated article on this but its possible that just 
setting your CLASSPATH doesn't really pick up your new xerces parser. 
Fire up tomcat with this flag

-Djava.endorsed.dirs=$CATALINA_HOME/common/endorsed

(make sure to put the new JAR files in that directory).. check out 

http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-
howto.html and scroll down to the section XML Parsers and JDK 1.4 
towards the bottom.

Hope that helps

Fw: Tomcat 4.1.18 jspc problem.

2003-01-02 Thread Alexey Kozadaev

Hello everyone,

I'm experiencing a problem with jspc. It always returns
NullPointerException, no matter what .jsp file I compile. Although it works
thru ?jsp_precompile, unfortunately we have a very big web site where plenty
of jsp files and they are have certain, complex structured layout in
filesystem, so I think writing a script, that would connect to tomcat with
?jsp_precompile would not be a good idea.

I am using FreeBSD 4.6, Tomcat 4.1.18, j2sdk_1.4.1_01 on linux base.

Does anyone know is there still a way to work with jspc or jasper jspc on my
system???

Or, you have the Jk2 developers write it for you. :-)

However, Craig is correct that you don't configure this in server.xml.  You
do it in jk2.properties.  I haven't really tried to play with the Unix
sockets yet, so I the best that I can do is to tell you how I understand the
config process.

You need to specify the 'handlers.list' property something like (although
I'm not certain that this is exactly right):
  handlers.list=apr,request,container,channelUnix

Of course, you have to set the 'channelUnix.file' property to point to the
socket.

Now, as long as you have configured mod_jk2.so the same way (e.g. using the
same properties file), it should work.

Same here, in most cases, and me neither.  Just out of curiousity, when do
you think you'll finally get off of JServ?  We're thinking of doing it
fairly soon, and I'm curious about your experiences.

tomcat-4.0.3

The prior mail was sent before I could complete.
Therefore, I am posting my question again.

I am trying to run a JSP using tomcat-4.0.3 and it
gives me an error "method flushBuffer() has protected
access in class
org.apache.jasper.runtime.JspWriterImpl". This error
does not occur when I use tomcat-4.0.1. The resulting
servlet has the following code:
public void _jspService(HttpServletRequest request,
HttpServletResponse response)
throws java.io.IOException, ServletException {

..
...
finally {
if (out instanceof
org.apache.jasper.runtime.JspWriterImpl) { 
((org.apache.jasper.runtime.JspWriterImpl)out).flushBuffer();
}
if (_jspxFactory != null)
_jspxFactory.releasePageContext(pageContext);
}

Any help would be appreciated. Thanks in advance.

Hi Rob,

Users are authenticated not Tomcat, so starting Tomcat has nothing to do
with authentication.  Tomcat is just a Java program.

When a user tries to access a web app Tomcat will authenticate that user if
that web app's web.xml file tells it to. The manager app is set up to
require authentication .

The web.xml file for admin is in
CATALINA_HOME/server/webapps/admin/WEB-INF/web.xml, you can see how it is
set up there.  If you want to authenticate users for your own web apps, set
up their web.xml security roles in a similar fashion.

A couple of other things you can check:

Should  userNameCol="usename" be userNameCol="username" ?

Can you access Postgres data from that file in your web apps using that
driver and username/password?  You should be able to write a simple program
to read the role names from the database.

Within Postgres have you granted select privleges to the database table in
template1 to the user tomcat in the tables pg_shadow and pg_groupview?

Can you use a db browser tool to log in as tomcat and execute an SQL command
like: SELECT groname FROM TABLE pg_groupview WHERE usename IS 'tomcat'?

RE: Code works in editor, but not through Tomcat - Please help!


We use the Sun tool, it used to be called Forte.  It's free, I think it is
called SunONE or something now.

Oracle's tool is free (certain editions) as well, but if you code with it
you have to follow special instructions to deploy to Tomcat (instructions
are on the Oracle site). 

There is also eclipse from IBM, also free, I believe.

That seemed to do it.  I know of naming conventions when writing Java
programs, but have never seen an instance that the naming convention was an
absolute rule.  

Thanks for your help :)

Completely off topic - but can you suggest a good JSP editor?  Coding in a
plain text editor like notepad can get frustrating.  I have a trial version
of JBuilder Enterprise, but it's a CPU hog, and it doesn't seem to help much
in the JSP department.

Denise,

The first thing that immediately came to mind is to check your setters and
form parameters for the appropriate case usage.  Your "PostalCode" should be
"postalCode" in both the form and the JSP actions.  If you don't understand,
I'll go into more detail regarding naming conventions for bean properties.

RE: can tomcat do dynamic virtual hosts?

I think you're overthinking it.  Tomcat != Apache.  Webapps != Document
Roots.

Tomcat needs to do what it needs to do because a web app is more than just a
directory that has content in it.

You can't map a.myhost.com to /examples/a and b.myhost.com to examples/b for
a very good reason.  There's no such thing as /examples/a and /examples/b.
If you want that you setup /examples-a and /examples-b, which you CAN do
with the auto-deploy function.

Don't make Apache = Tomcat...they're completely different, not just in name
and codebase, but also in purpose, intent, and design.

On that note, anyone who tries to do power hosting with Tomcat in a single
instance is being foolish, but that's my own personal opinion.  My
production servers are using Jserv, but I wouldn't think of using a single
Tomcat instance for all of my virtual hosts.  Doesn't make any sense at all.
>From a user standpoint, if I was paying $30 a month or whatever for hosting,
and my ISP told me that they couldn't restart my application because it
would effect others, or that my application was going to be down because
someone else's application was causing problems, I'd be pretty upset.  From
that perspective, Tomcat does virtual hosting just fine, using separate
instances, provided you have the resources.

That means that all myhost.com/examples can be passed to tomcat, who looks
at 
myhost.com/examples and does its own mapping to find the right context.  It
doesn't mean 
that you can map myhost.com/some/arbirtray/path to the examples webapp
(unless you also 
change the tomcat config) and it doesn't mean you can map a.myhost.com to
/examples/a and 
b.myhost.com to /examples/b and it doesn't mean you can map *.myhost.com to
/examples/%0 
where %0 is what is in *.  Or not as far as I can tell, anyway. JServ is
much more 
flexible in this regard.

On another note I've totally given up on the apache autoconfiguration
because of its 
inconsistant behavior.

Re: Tomcat 5 and CATALINA_BASE/shared/lib problem...


Just a little follow-up to what I said below.  I had surmised that maybe 
CATALINA_HOME/shared/lib libraries where simply getting loaded first and 
maybe CATALINA_BASE/shared/lib libraries that had the same packages 
wouldn't be loaded because they would only be loaded once by Tomcat.  Well, 
this is false.  CATALINA_BASE/shared/lib is entirely ignored and libraries 
from CATALINA_HOME/shared/lib are always loaded even if CATALINA_BASE is 
set to a value different from CATALINA_HOME.

This is either a bug in Tomcat5 or a conscious decision was made to change 
the behavior or Tomcat5 -vs- Tomcat-4.1.x (and probably also Tomcat-4.0.x).

Can anyone confirm this?  Should I report this as a bug in Bugzilla?

Hi all,

Using Tomcat-4.1.x, I can have separate instances of Tomcat running which 
access their own shared/lib folder.  In Tomcat-5.0 latest nightly build, 
that doesn't seem to be the case.

For instance, using Tomcat-4.1.18, if I have some jars in 
CATALINA_HOME/shared/lib and I start up a new tomcat instance with 
CATALINA_BASE set as something other than CATALINA_HOME, the jars in 
CATALINA_HOME/shared/lib will *not* be loaded.  Instead, jars will be 
loaded from CATALINA_BASE/shared/lib (if it exists).  This is the behavior 
I expect and love!

However, using Tomcat-5.0, if I set things up the same way, jars in 
CATALNIA_HOME/shared/lib *will* be loaded and jars in 
CATALNIA_BASE/shared/lib are completely ignoredor it could be that it 
is picking up both of them, but loading jars in CATALINA_HOME/shared/lib 
first and then looking in CATALINA_BASE/shared/lib.  If a jar in the 
latter contains the same packages that were already loaded in the former, 
then the latter is ignored.  Either way, Tomcat-4.1.x completely ignores 
CATALINA_HOME/shared/lib if CATALINA_BASE is set and is different from 
CATALINA_HOME where Tomcat-5 loads CATALINA_HOME/shared/lib jars no matter 
what.  This is behavior that I don't expect and don't like.

I used the ability to separate instances to run apps which required 
different versions of xerces.  I put xerces-1.4.4.jar in 
CATALINA_HOME/shared/lib for apps which I use most often.  However, I have 
other apps that need either slightly modified version of xerces-1.4.4 or 
require xerces-2.x.x.  For those cases, I run a separate instance of 
Tomcat using a custom set CATALNIA_BASE with a local shared/lib with the 
appropriately versioned jars that I need for this particular app.

So, this is a great feature in Tomcat-4.1.x (and, I imagine, Tomcat-4.0.x) 
but it seems to be broken in Tomcat-5.0.  Is this new behavior in 
Tomcat-5.0 a bug or was it intentional?  If it was intentional, can 
someone explain the reasons for the change in behavior to that of Tomcat-4.1.x?

tomcat binds only to localhost??

2003-01-02 Thread Ronny Haryanto

Hi everyone,

I have a strange problem with Tomcat 4.1.18 on Windows 2000. The
machine has one ethernet, dhcp enabled, and the primary ip is
192.168.1.2 (LAN) and it is also accessible via 202.157.154.130 
and seatech.com.

I can only access Tomcat via http://localhost:8080 from the machine
itself, but not http://seatech.com:8080 even though seatech.com
clearly resolves to 202.157.154.130 and I don't configure Tomcat to
listen to one specific address/interface in server.xml (the default is
that Tomcat listens to any available address, right?). I also checked
the logs for errors, but I didn't see any.

Am I missing something? I would greatly appreciate any help or
suggestions. Thank you for your time.

Regards,

Ronny

Yeah, I saw that blurb. That's unfortunate, because in truth this is the
crux of your problem. It is not so bad that a popular JSP gets cached into
RAM, that is a good thing. That is what RAM is for. However, in this case,
even the rarest and most unpopular of your JSPs are getting cached
permanently. Owie.

Are you able to isolate a particular instance/server so that current users
can continue with the site, while no new users go there? If that is possible
with your configuration, then you do not really have a session problem as
they should be invalid by the user logging out/going away/timing out.

To be fair, replacing JSP with Velocity, particularly a JSP generated by
another program (i.e. not written directly by a CBL (Carbon Based Lifeform))
implies that the execution of the compiled JSP page is slower than the
intpretation of the Velocity template (modulo the fact that Tomcat does not
GC JSPs, but that is a detail for this discussion). I do not have any data
either way as to which is faster.

In truth, there is not anything really wrong with your overall design. Most
complaints about JSP focus on maintainability of the JSP files, and the
intermixing of code and HTML etc. Velocity implicity suffers from that same
issue, though perhaps its syntax and model may be better. But these are not
direct issues with your system, as your JSPs are derivative products of your
CMS system. In my opinion, your use of JSPs here is no different from using
something akin to the Olde Tyme Server Side Includes. The facts seem to be
that save for the memory issue, you system is behaving fine, and, as you
noted, your JSP solution appears to scale better.

And well it should with all of your pages cached in RAM :-).

So, I would look at the other message in the list that mentioned the Jasper
class loaders hash table and perhaps changing that to support an LRU queue
rather than a hash table.

I know it is a complicated and not necessarily well understood area for most
developers, but it IS the source of your problem. I think that if you spend
a little bit of time in that section of code, you have a better chance for
success in a shorter amount of time. Also, once you load test the heck out
of if and stress it as best as you can, it is probably much safer as from a
logical or even implementation point of view, your application does not
change at all. Ideally, it can simply be a change from a HashTable (or
HashMap, whatever they are using) to an LRUMap (of somekind, this is left as
an exercise for the reader :-) -- maybe you can safely use WeakReferences
here), with all of the Real Hard Work (tm) done by the surrounding code.

Granted, this means you must go through the nightmare of actually BUILDING
Tomcat (not for the meek).

The code in place already deals with loading class files, checking the map
for loaded classes, synchronization issues, etc. So what is the difference
between checking a HashMap for a class and loading it if it does not exist
(in this case the first time the page is loaded), and seeing that the class
is not there because it happened to drop off the end of the queue? It should
not matter why the class is not in the map, but simply that it is not there.

For normal operations and classes, this is less of an issue, but your
classes are really content so they suck up an extraordinary amount of
memory.

You'd best examine the sources to figure that out :-).  But Jasper2 is
radically different than Jasper1.

But remember, it's not just a matter of throwing away the reference to the
compiled servlet class.  You also need to ensure that the destroy() method
gets called as the servlet API requires -- all the while ensuring that no
additional requests start getting processed through the service method.

And, don't forget that this will harm performance for the vast majority of
users who *do* have adequate memory on their servers, so nothing like this
should be enabled by default.

Did someone manage to use a non default channel port for tomcat4.1.18 JK2/ajp13 ?

2003-01-02 Thread Lacoste (Frisurf)

I finally solved the problem I described in my emails titled:
"tomcat/apache connector startup failure: NCDFE fpr
org/apache/commons/logging/LogFactory"

sent both to the tomcat-user and tomcat-dev list.

I was trying to use a non-default channel port (8019) in my
configuration, following a working worklog of someone that had been
using tomcat 4.1.12.

Reverting to port 8009 solved the problem.

When I look at the logs it seems that the configuration file doesn't
seem to be used. If I set channelSocket.port=8019 in the jk2.properties,
it has no impact. I get an exception as described in my former emails
(pasted below). Using 8009, no exception is thrown and apr initializes
correctly.

So I am wondering if somebody else has tried using a different channel
port than the default 8009 with tomcat (lite) 4.1.18.

Thanks a lot for those whose can test their working config, using a
different port.

Cheers,

Jerome

Instances can be garbage collected IF AND ONLY IF there are no live
references to that object in a static/instance/local variable of some
other object that is also in memory.  Only instances that are no longer
referenced from other object instances can be recycled.

In the case at hand, Tomcat (obviously) has references to all the servlets
that it has loaded.  Therefore, those servlet instances cannot be garbage
collected.  Furthermore, any object that is referenced by static or
instance variables of your servlet class can *also* not be garbage
collected, because live references still exist.  Same thing for session
attributes.

In the very early days of Java, classes themselves could be GC'd if there
were no live instances of that class.  However, this caused more grief
than it was worth, so that went away (about JDK 1.1 or so).  In today's
world, the only way to throw away a class instance is to throw away the
class loader that loaded it (which is how Tomcat implements webapp
reloading).

As above, instances ALWAYS stay in memory as long as there are live
references.  If there are no live references, the GC is free to clean them
up if and when it feels like it.

As above, you can throw away references to a ClassLoader, and that will
ultimately cause all the instances to be collected -- but ONLY if there
are not any references to any instances of classes loaded by that
ClassLoader somewhere else.

Phew, that doesn't make sense -- can we describe a sample use case?

Sure.  Consider the fact that Tomcat provides more than one class loader
(see
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html).
The common and shared class loaders are never thrown away, so any classes
loaded from there will stay in memory for the lifetime of Tomcat.  But
wait, there's more.

Assume that you've got a class, loaded from a library in common/lib, that
maintains a collection as a static variable.  Now, assume you've called a
method on this class, and passed it a reference to a bean (or something)
that is loaded from your webapp (i.e. it's in WEB-INF/classes or
WEB-INF/lib), and this reference gets added to the static collection.
Now, ask Tomcat to reload this application.  What happens?

Tomcat dutifully throws away its reference to the webapp class loader.
Normally, that means everything loaded from that class loader is now
garbage and can be collected.  HOWEVER, because there is still a live
reference to one of the objects from your old webapp in the static
collection.  Therefore, GC cannot process:
* The instance of your bean class that was referenced
* The class of your bean
* The webapp class loader
* Any other objects referenced by the webapp class loader.

In short, the above scenario just created a memory leak.

The best thing you can do to avoid problems like this is to make your
webapps self contained, and to always release references to objects you
don't need any longer.

As of 4.0.4 tomcat keeps a reference to every generated servlet, so
increasing the memory size only delays the OutOfMemoryError.

In fact we are using loadbalancing using apache 1.3.26, mod_jk, and 3 tomcat
instances.
Every night one tomcat get's restarted. Basically we use the lb-options
local_worker  & local_worker_only to disable a tomcat instance at midnight
and restart it at 4:00.


Otherwise the big problem with restarting tomcat is loss of our
session-data.
Saving and restoring the data in the SESSIONS.ser file doesn't help, since
the loadbalancer routes the web clients to another tomcat instance where
they get another sessionId.

I once experimented with tomcat clustering using the source from
http://www.filip.net/tomcat/ but this was some months ago and didn't work
very well at this early stage .

Re: Memory Usage and Garbage Collection

2003-01-02 Thread Julian Löffelhardt

Looking at the jasper source of tomcat 4.0.4 releasing jsp's seems to be
reasonable easy to implement:
The Jsp's classloader, the class and the actual jsp-servlet instance  are
all put together in a JspServletWrapper-Object which itself is stored in the
JspServlet (the Servlet used to executing jsps) using a Hashtable.
One could replace the hashtable with a LRU-Cache or anything.

Since each jsp is loaded using a separate classloader, removing the Wrapper
removes the reference to the instance, it's class and it's loader, which
should enable the class garbage collector to remove the class.

Do you think this approach is reasonable?
Does this part of the implementation differ with Jasper2?

This is a feature I could really use well.

julian

RE: Memory Usage and Garbage Collection

Craig,

Thanks for your comments, I still have a few clarification questions.

1)It's not just the classes -- it's the object instances created from those
classes that take up space (the bytecodes of the class itself exist only
once).  ---does this mean that every object instance is never garbage
collected, or are these instances collected?

2)What about instances of the classes, does every instance stay in memory
forever?  Are they loaded into the sessions, or are they pooled somehow?
What about the instance variables of these classes, I assume they get
collected after the class instances would be collected.

If class instances stay in memory forever, I would think there is no
possible way to ever keep the system running without a restart.

It's legal for servlet containers to destroy and release servlets and JSP
pages while the server is running, but Tomcat doesn't currently do so.
Once a servlet or JSP is loaded, it stays loaded until you reload that
particular webapp or you shut Tomcat down.

If you're using swap space, you probably have your max heap size (-Xmx)
too large for the amount of physical memory that is available.  I'd
definitely start by either reducing -Xmx or increasing the amount of
physical RAM.  If reducing -Xmx gives you OutOfMemoryException errors,
then increasing RAM is the only option.

The second thing I'd do is review my applications for places where they
might be maintaining references to data in between requests, either in
instance variables of the servlet or JSP class or by keeping too many
things in the user's session for too long.  If there are such references,
your user data objects cannot be GC'd and you'll end up with exactly the
pattern you describe (slowly increasing memory use).

Re: JDBCRealm

2003-01-02 Thread Rob Abernethy IV

Ok, I tried cleartext passwords, but I came up with the same result.  I don't
understand why tomcat is able to start up at all, if the authentication is
failing.  When I run 'ps' after starting up tomcat, I see this process:

40 S postgres  2825  2758  0  75   0-  2431 schedu 18:12 pts/000:00:00
postgres: tomcat template1 24.208.224.236 idle in transaction

Seeing this makes me believe that Tomcat is correctlty connecting to the
database at startup.  Is this true?  If so, why can't the admin or manager
apps authenticate?  They are using the same Realm (it's nested inside the
 tag) and I'm supplying the same username and password.

Tomcat 5 and CATALINA_BASE/shared/lib problem...


Hi all,

Using Tomcat-4.1.x, I can have separate instances of Tomcat running which 
access their own shared/lib folder.  In Tomcat-5.0 latest nightly build, 
that doesn't seem to be the case.

For instance, using Tomcat-4.1.18, if I have some jars in 
CATALINA_HOME/shared/lib and I start up a new tomcat instance with 
CATALINA_BASE set as something other than CATALINA_HOME, the jars in 
CATALINA_HOME/shared/lib will *not* be loaded.  Instead, jars will be 
loaded from CATALINA_BASE/shared/lib (if it exists).  This is the behavior 
I expect and love!

However, using Tomcat-5.0, if I set things up the same way, jars in 
CATALNIA_HOME/shared/lib *will* be loaded and jars in 
CATALNIA_BASE/shared/lib are completely ignoredor it could be that it 
is picking up both of them, but loading jars in CATALINA_HOME/shared/lib 
first and then looking in CATALINA_BASE/shared/lib.  If a jar in the latter 
contains the same packages that were already loaded in the former, then the 
latter is ignored.  Either way, Tomcat-4.1.x completely ignores 
CATALINA_HOME/shared/lib if CATALINA_BASE is set and is different from 
CATALINA_HOME where Tomcat-5 loads CATALINA_HOME/shared/lib jars no matter 
what.  This is behavior that I don't expect and don't like.

I used the ability to separate instances to run apps which required 
different versions of xerces.  I put xerces-1.4.4.jar in 
CATALINA_HOME/shared/lib for apps which I use most often.  However, I have 
other apps that need either slightly modified version of xerces-1.4.4 or 
require xerces-2.x.x.  For those cases, I run a separate instance of Tomcat 
using a custom set CATALNIA_BASE with a local shared/lib with the 
appropriately versioned jars that I need for this particular app.

So, this is a great feature in Tomcat-4.1.x (and, I imagine, Tomcat-4.0.x) 
but it seems to be broken in Tomcat-5.0.  Is this new behavior in 
Tomcat-5.0 a bug or was it intentional?  If it was intentional, can someone 
explain the reasons for the change in behavior to that of Tomcat-4.1.x?

Thanks,

Jake

Re: reducing tomcat & jasper memory footprint

2003-01-02 Thread Will Hartung

There are a lot of issues that show up here.

1) Using the JSP means that the entire article text (among other things) is
being cached into RAM.
2) Some of the pages are "popular" enough that they are getting moved into
the permanent area of memory, and thus avoiding the routine, "cheap" GCs.
3) The question whether Tomcat is somehow "holding on" to the JSP references
to prevent them from being GC'd at all (I don't think this is the case, but
you never know).

As for solutions, there are several, none of which are particularly elegant
I don't think.

First, of course, "Buy more RAM", also pronounced "Let's make our Full GC's
take even LONGER!".

Another is to simply reboot Tomcat during a "quiet" time. At least this way,
the down time is predictable rather than having it "Crash" at an unscheduled
time. If the restart time is fast enough, and the site quiet enough, this
may effectively solve the issue. You mentioned that the system is running
several days reliably now, so, perhaps a nightly restart is not a horrible
concession.

Another is to mirror the site behind some kind of load balancer so that
restarting the site does not actually affect users, and then go to solution
one. Oh boy, more hardware to configure.

You can "rengineer" the site.

If your JSPs are reasonably regular to the point where you can write fairly
simple filters to extract the actual content without resorting to crafting a
JSP parser, then that is a good first step.

So, going on the crass assumption that getting the article text out of your
generated JSPs is not an onerous task, then the next step, to me, would be
to stick a servlet Filter in front of every request.

This Magic Filter (a notable anti-pattern, but...) is configured so that you
will not have to actually update and rewrite all of the zillion URLs
scattered throughout the site.

So, www.yoursite.com/area/document.jsp in the "old" site is the same in the
"new" site.

The Magic Filter determines if the JSP file is a "real" jsp (no doubt you
have some JSPs that do something other than dump static articles), versus
one of your generated documents.

If it is one of your generated documents, then the Magic Filter rips it
apart, caches it perhaps (the ripped text), and then serves it up in a new
shiny generic way as should have been done originally. If not, you let the
Filter drop through and pass on so the container can handle the JSP requiest
and go its merry way.

Ideally, this can be done with very little change to the site, and certainly
no change to the production CMS, it's ignorant of the change. Your web.xml
"simply" has a new Filter element, and voila!

I am not suggesting that this is easy or painless, but if your generated
JSPs are able to be easily torn apart, then I think it's viable and
practical.

Perhaps your CMS JSP template can be recoded to add some comments (like

This is my article
) that makes it easy to find articles. Perhaps you
can then REGENERATE all of your older content to use the new template. You'd
like to think that your CMS will allow this (kind of the whole point of a
CMS at some level, isn't it?).

Or, if you can not regenerate your older content, have the Magic Filter
"detect" old vs. new and simply "execute" the old ones (as noted above), and
filter the new ones. If your site is mostly newer content, then the old
stuff will drift away and be less of a problem over time.

Once up and running, your Magic Filter can cache and keep track of the
status of various JSPs it encounters so as not to have to rework them each
time.

I would vote for the "restart nightly" technique and look into ways of
tweaking the CMS system to spit out something you can use, but that's me.

The other problem with this technique is that it is doing processing at run
time which could best be done statically.

For example, the fact that your CMS is generating JSPs, perhaps you can
place a step in the production step that performs the parsing for you, that
way it is done at production time versus request time. It depends on how
easily you can modify your work flow from the CMS into the site proper.

Since your jsp's are generated, they should all have the same formatting.
Write some code to rewrite your own non jsp pages that you can then later
insert into a single jsp. Sure its some work, but in the long run it will
save you some aggravation.

If tomcat can rewrite your jsp on the fly, so can you.

host.  As time goes on, the amount of memory being used constantly grows.
It starts off around 60MB, then goes higher and higher, getting up to around
100MB after a couple days.

The regular GC seems to usually clean up around 2MB ([GC
99493K->97502K(204544K), 0.0243521 secs]) and the Full GC seems to clean up
less than that ([Full GC 97388K->97187K(204544K), 2.4269915 secs]).

Since I have the -Xmx and -Xms set to 200MB, the 204544K number never gets
resized, but the number before the -> seems to slowly and steadily rise.

Full GC seems to run quite often, every few seconds, GC runs once in a
while, but spits out about 50 lines at once every time it runs.  Is this
normal?  Shouldn't Full GC only run once in a while?

I am starting to think that as classes and jsp's are loaded, they stay in
memory and are never released until tomcat is restarted, which means that
there is eventually a point where all the classes will load and I just need
to have enough memory to support that without having to use swap space.

The problem occurs when the memory usage number before the -> gets up to
about 130.  The system is using swap space and eventually out of memory
errors start showing up.

Any ideas?  More Ram, more tuning, different site architecture?

Thanks in advance?

Re: Code works in editor, but not through Tomcat - Please help!

Denise,

I use Dreamweaver for presentation, SunOne (which is based on NetBeans) to
manage the project and CodeWright from StarBase as the text editor (it is
far and away better than the editor in JBuilder or SunOne.)

RE: Easy question - Java Beans

Here's a sample from a form that uses states.  The states are generated from
a class to keep less java on the jsp page, but you can see how the options
are generated and set to selected if they match the value in the bean.




Choose a State

<%State[] states = State.getAll();
  for(int i=0; i

<%if(ab.equals(setupBean.getAgentState())){%>selected<%}%>><%=nm%>
<%}%>
  


Hope that helps!

Re: can tomcat do dynamic virtual hosts?

Hmmm...you lost me there.  Yes, you do map to a Context directly, at least

you can pick up both new virtual hosts and new JkMounts for those virtual

On the Apache side, what more does there need to be?  

That means that all myhost.com/examples can be passed to tomcat, who looks at 
myhost.com/examples and does its own mapping to find the right context.  It doesn't mean 
that you can map myhost.com/some/arbirtray/path to the examples webapp (unless you also 
change the tomcat config) and it doesn't mean you can map a.myhost.com to /examples/a and 
b.myhost.com to /examples/b and it doesn't mean you can map *.myhost.com to /examples/%0 
where %0 is what is in *.  Or not as far as I can tell, anyway. JServ is much more 
flexible in this regard.

On another note I've totally given up on the apache autoconfiguration because of its 
inconsistant behavior.

Apache already supports dynamic virtual hosting. See 
http://httpd.apache.org/docs-2.0/vhosts/mass.html. That's what I'm talking
about. The 
problem is that when connecting apache to tomcat you can't map into a
contect directly, 
you only pass the request along to tomcat so somcat has to find the proper
 based on 
the requested host name. If the connector could map directly into a context
then Apache 
could do something like:
JkMount /* worker1:mycontext/%0/

Re: Tomcat, Apache and PHP

John,

I changed the order of Virtual Hosts in httpd.conf
and put the PHP site as the first one - which becomes the default - and now
the JSP site is served by Tomcat and the  PHP site is at least found  by
Apache.
I guess there is something not quite right as the site should have been
picked up without it
being the default and now although the site (phpMyAdmin) is found it is not
being served quite correctly.

Re: JDBCRealm

2003-01-02 Thread Rick Fincher

Hi Rob,

Try it in clear text without the MD5 digest, to verify that your password,
username, role, etc are correct.

I had a lot of problems with digesting.

Also some databases return column names in upper case even if they are in
lower case so you may want to try all caps on your db column names.  I think
you would get a different eror message if this was the case, though.

OT - java:comp/env issues in standalone unit testing

2003-01-02 Thread Mark

I'm trying to set up standalone Ant-JUnit testing for our model objects 
which can be tested independent of our controller/view components. Problem 
is we have a lot of environment  properties in web.xml, such as 
DAO class names used in factories and other run-time stuffso we have 
many instances of code like this:

   Context initCtx = new InitialContext();
   propertyXYZValue = (String)initCtx.lookup("java:comp/env/propertyXYZ");

From what I understand the container establishes a java:comp/env 
context-subcontext per web app, so attempting to get properties w/o using 
Tomcat fails.

Has anyone else run into this situation, and if so how'd you get around it, 
ie. manually create a java:comp/env context and add necessary env entries? 
Other suggestions?  Am I looking at this from a really screwed up 
perspective?  I've looked at Cactus a little and it seems like it's 
something we'd want eventually, but also seems more complex than what we 
need today.

Any thoughts will be appreciated.

Thanks
Mark

Re: can tomcat do dynamic virtual hosts?

2003-01-02 Thread Joseph Shraibman

Sorry, having a bad keyboard day. 'contect' should be context and 'somcat' should be tomcat.

Apache could do something like:
JkMount /* worker1:mycontext/%0/

RE: Code works in editor, but not through Tomcat - Please help!

I will look into all that you suggested.  The weird thing is though, that it
only happens with those three parameters.  Everything else goes through
fine.  I checked the form code for differences between other parameters and
the three offending parameters, but everything is the same

Thanks.

Denise,

I had the same problem once.  All my calls to getProperties were coming back
null.  It turned out to be a pathing issue in my form.  I'm not sure why it
even ran the JSP with the incorrect path inside ACTION parameter of the form
but it did run and it returned null values for all the properties.  It
nearly drove me to drink(at work) and I screamed several times and said many
bad words until I figured it out.  It had to do with my JkMount statement,
my default classpath(tomcat), and my path inside the ACTION parameter.  You
might try calling it different ways to see if that helps.

I tried to "echo print" the value of the PostalCode after it has been picked
up by the bean, by calling .  And I get an error message stating :

org.apache.jasper.JasperException: Cannot find any information on property
'PostalCode' in a bean of type 'com.complusdata.beans.FormBean'

When I complete the Form, I type in 12345 in the input box and yet it seems

Hi all.  This one's kind of urgent because its holding up the rest of my
project...

I'm not sure I understand why this is happening. I have a bean that I use
for form validation.  When I test the code locally using an editor and hard
coding variable values, the code runs perfect and all information is
validated (i.e. check zip code length =5, check zip code is a number, check
credit card number is a number, check all fields are filled in etc").
However, when I try to validate my form through Tomcat I keep getting errors
on the same fields over and over.

Any idea why this would be happening?  I have posted my code below just in
case, but since it worked when I ran it in the editor, I do not think the
problem is my code.  The only thing I can think of is that somehow,
something screwy is happening when my bean properties are being set

Thanks in advance!
Denise

Errors (only get these over Tomcat):

I enter 12345 as zip code, and I get "Please enter a valid zip code." error
message (The second error only comes up when I try a non numeric zip so that
part works ok). Input type is text and bean variable is string. The Code:
 if (PostalCode.equals("") || PostalCode.length() != 5 )
{
errors.put("PostalCode","Please enter a valid zip code.");
PostalCode="";
allOk=false;
}
else
{
  try {
int x = Integer.parseInt(PostalCode);
  } catch (NumberFormatException e) {
errors.put("PostalCode","Please enter a valid 5 digit zip
code.");
PostalCode="";
allOk=false;
  }
}

I enter 12/03 for Expiration date, and keep getting invalid message.  Input
type is text, and bean variable in bean is a String. The Code:
if (Expires.equals(""))
{
   errors.put("Expires","Please enter expiration date as
MM/YY.");
   Expires="";
   allOk=false;
}

I try [EMAIL PROTECTED] for both email and retype email.  Input type is text
and bean variable is string. Here is the code:
if (Email.equals("") || (Email.indexOf("@") <= 0))
{
errors.put("Email","Please enter a valid email address.");
Email="";
allOk=false;
}
else if (!Email.equals(retypeemail))
{
errors.put("Email","The emails entered do not match.");
Email = "";
retypeemail="";
allOk=false;

Re: can tomcat do dynamic virtual hosts?

2003-01-02 Thread Joseph Shraibman

Apache already supports dynamic virtual hosting. See 
http://httpd.apache.org/docs-2.0/vhosts/mass.html. That's what I'm talking about. The 
problem is that when connecting apache to tomcat you can't map into a contect directly, 
you only pass the request along to tomcat so somcat has to find the proper  based on 
the requested host name. If the connector could map directly into a context then Apache 
could do something like:
JkMount /* worker1:mycontext/%0/

As for the web connectors, you'll need to ask someone who understands and

this is going to be a challenge -- but that's outside my area of

Re: Tomcat, Apache and PHP

2003-01-02 Thread John Bell

John,

I changed the order of Virtual Hosts in httpd.conf
and put the PHP site as the first one - which becomes the default - and now
the JSP site is served by Tomcat and the  PHP site is at least found  by
Apache.
I guess there is something not quite right as the site should have been
picked up without it
being the default and now although the site (phpMyAdmin) is found it is not
being served quite correctly.

Re: jdbc, mysql and character encoding

2003-01-02 Thread Anastasios Angelidis

Well I know for a fact that if you are using windows, the console window 
canot display extended characters. Only the standard ASCII chars...

It doesnt really matter, as long as you get the desired result in your 
application...

All characters in the end are bytes, a byte is a byte it all depends how 
each application interprets the bytes and displays them. So if the the 
console application uses the standard printf functions etc... you will 
see the weird characters ;)

Everything works fine, and when I print the content of the db with the getString mehotd, I see my characters.
The problem is that when I go to the MySQL prompt, I can see strange characters isntead of the ones I tried to write.

MySQL uses the default ISO-8859-1 encoding, and since I'm telling to the JDBC driver to use ISO-8859-1, I can't explain what's wrong

Denise,

I had the same problem once.  All my calls to getProperties were coming back
null.  It turned out to be a pathing issue in my form.  I'm not sure why it
even ran the JSP with the incorrect path inside ACTION parameter of the form
but it did run and it returned null values for all the properties.  It
nearly drove me to drink(at work) and I screamed several times and said many
bad words until I figured it out.  It had to do with my JkMount statement,
my default classpath(tomcat), and my path inside the ACTION parameter.  You
might try calling it different ways to see if that helps.

RE: is this normal??

2003-01-02 Thread Ben Ricker

I found a trick that might help: up your sar reports to take a snapshot
every minute. Then, when you notice the CPU pegging, go through the sar
reports for CPU usage and try to find the minute that they start. Then,
you can go back through the Apache access logs (mod_jk.log perhaps),
etc. to see if you can correlate a specific request with the the
problem.

Good Luck,

When server.xml is parsed at Tomcat startup time, the executed code
creates instances of the internal Catalina objects that correspond to each
element -- for example, a  declaration causes the creation of a new
instance of "org.apache.catalina.core.StandardHost" -- that is then
configured with the properties and attached to the owning object (in the
case of a host, it's the o.a.c.c.StandardEngine instance that corresponds
to the  element).

The admin webapp simply performs the same operation, but at runtime (no
restart required).

No there's not.  Even if it were to be implemented, I'm betting that the
time required would be essentially equivalent to shutdown/restart.  It's
also irrelevant for the things that can be changed dynamically (such as
adding a virtual host), except for the fact that the web connector stuff
probably doesn't respect dynamic changes like this (I don't have a clue on
that part).

In principle, it would be pretty straightforward to extend the manager
webapp to do things like this (so that it would be easily scriptable from
a command line or Ant script).  In fact, there's discussion on the
developer list, with respect to Tomcat 5, to enabling pretty much all of
the administrative change type features via JMX (which is what the admin
webapp is already using) and making them available remotely.  A small
amount of refactoring inside Catalina will be required to make this work
(such as making the startup code that reads server.xml just use the same
JMX operations instead of duplicating things), but that's not a huge
amount of work.

As for the web connectors, you'll need to ask someone who understands and
works on them what the plans are for supporting dynamic configuration
changes.  Given that Apache doesn't appear to support them, I would guess
this is going to be a challenge -- but that's outside my area of
expertise.

I have enabled server stats (thanks Jan)

I stop and started and it is back to normal. So when this does this

Thanks for all the suggestions

jdbc, mysql and character encoding

2003-01-02 Thread [EMAIL PROTECTED]

I've my jsp, where I simply want to fill a table with some "italian" characters:

<%
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection 
("jdbc:mysql://localhost:3306/jdbctest?useUnicode=true&characterEncoding=ISO-8859-1", 
"usrjdbc", "pwd");
Statement stmt = conn.createStatement();
stmt.executeUpdate("INSERT INTO table (text) VALUES ('àèìùò')");
ResultSet rs = stmt.executeQuery("SELECT * FROM table");
while (rs.next()) {
   int id = rs.getInt("id");
   String text = rs.getString("text");
   out.print("row#" + rs.getRow() + ": id=" + id + ", text=" + text);
   out.println("");
}
stmt.close();
conn.close();
%>

Everything works fine, and when I print the content of the db with the getString 
mehotd, I see my characters.
The problem is that when I go to the MySQL prompt, I can see strange characters 
isntead of the ones I tried to write.

MySQL uses the default ISO-8859-1 encoding, and since I'm telling to the JDBC driver 
to use ISO-8859-1, I can't explain what's wrong

RE: can tomcat do dynamic virtual hosts?


H...interesting point.  What does the admin webapp do, then, that you
couldn't do from the command line?  Is there something similar to Apache's
'apachectl restart' for Tomcat?

Can you call the admin webapp with a URL and have it do things?  If so,
that's the answer to the original post...you would just need a script to
send the appropriate command, much like ant would or whatever, to the admin
webapp.

Code works in editor, but not through Tomcat - Please help!

Hi all.  This one's kind of urgent because its holding up the rest of my
project...

I'm not sure I understand why this is happening. I have a bean that I use
for form validation.  When I test the code locally using an editor and hard
coding variable values, the code runs perfect and all information is
validated (i.e. check zip code length =5, check zip code is a number, check
credit card number is a number, check all fields are filled in etc").
However, when I try to validate my form through Tomcat I keep getting errors
on the same fields over and over.

Any idea why this would be happening?  I have posted my code below just in
case, but since it worked when I ran it in the editor, I do not think the
problem is my code.  The only thing I can think of is that somehow,
something screwy is happening when my bean properties are being set

Thanks in advance!
Denise

Errors (only get these over Tomcat):

I enter 12345 as zip code, and I get "Please enter a valid zip code." error
message (The second error only comes up when I try a non numeric zip so that
part works ok). Input type is text and bean variable is string.
The Code:
 if (PostalCode.equals("") || PostalCode.length() != 5 )
{
errors.put("PostalCode","Please enter a valid zip code.");
PostalCode="";
allOk=false;
}
else
{
  try {
int x = Integer.parseInt(PostalCode);
  } catch (NumberFormatException e) {
errors.put("PostalCode","Please enter a valid 5 digit zip
code.");
PostalCode="";
allOk=false;
  }
}

I enter 12/03 for Expiration date, and keep getting invalid message.  Input
type is text, and bean variable in bean is a String.
The Code:
if (Expires.equals(""))
{
   errors.put("Expires","Please enter expiration date as
MM/YY.");
   Expires="";
   allOk=false;
}

I try [EMAIL PROTECTED] for both email and retype email.  Input type is text
and bean variable is string.
Here is the code:
if (Email.equals("") || (Email.indexOf("@") <= 0))
{
errors.put("Email","Please enter a valid email address.");
Email="";
allOk=false;
}
else if (!Email.equals(retypeemail))
{
errors.put("Email","The emails entered do not match.");
Email = "";
retypeemail="";
allOk=false;
}

Re: RE: is this normal??

2003-01-02 Thread jmong

I have to concur with the following observation.

Try to check what the apache processes are doing. If you've enabled 
server-status on your box and have installed GET (as part of the perl 
LWP) grep for the pid

GET /server-status | grep 

or access it http:///server-status

On older tomcat versions (i.e. 3.2.1), it would seem that older 
clients (i.e. HTTP/1.0) would hang up on the POST part

ie.

POST /path/to/form/process.jsp HTTP/1.0

Typically my only recourse is to kill the offending process and/or 
restart tomcat and apache.

kill -9 

Hope that helps

Tomcat does not release references to the servlet.  In fact, it's totally
up to the container (not to you) to decide how long a servlet instance
will stay initialized.

What you want to do is make sure that your *servlet* does not maintain any
references to the report results for the previously generated report.
Then, those objects can get GC'd.

Of course, you're still going to have problems when multiple users ask for
reports to be generated at the same time, if you've only got enough memory
to do one -- but that's a separate issue.

There is probably a problem going on there. I find it strange that you
have so much cumulative CPU time on the httpd processes. To me, they
look hung (in so far as I can tell). Since most apps are transactional
in nature (i.e., individual requests being fulfilled rather quickly),
you would expect to see the Apache processes using CPU, then giving it
up rather quickly. Of course, other httpd processes will also pop in and
out of CPU usage as individual requests pop in.

How long has this Apache/Tomcat been running? You might try a restart of
both and see if the same behavior comes right back or if it takes time.
You may have an issue in the app which is triggering a hang.

Of course, on a "pretty busy web server", you may get such cumulative
times, but you should still see httpd processes popping in and out of
CPU usage as they handle their respective requests. If the same PIDs sit
there pegging the CPU incessently, you most likely have an issue.

No it does not! That would mean bad performance. I can not have my
clients block.

But if tomcat releases the reference to the servlet, the hole thing
should be garbage collected. The standard way of doing that is by
reference counting, right? And that should be enough, but apparently
not. How does incremental (I run 1.3) gc differ from ref counting? My
code sets variables to null before I "suggest" it to do gc.

I might try this when I start optimizing. Now am trying to get it to not
hold all my memory. Could it be a bug? Doesn't tomcat drop the reference
to the hole servlet when do_GET returns? To me it seems that it holds
every thing.

Re: Realm not working now I've moved from Win2K to Linux

2003-01-02 Thread Gary Gwin

Ben,

Can you see in your Tomcat log files if you are being forwarded back to
the original request page after authentication? If yes, and you are
being authenticated as you indicate, this sounds like the state is
somehow being lost. In this case, you might be in a forwarding loop
between the protected resources and the login page. I'm not sure on why
this would be happening.

You might take a look at our Cams product: http://www.cafesoft.com

Cams unifies Apache and Tomcat security under a centralized security
policy umbrella. It is tested under Windows and Linux to work via JDBC.

Good luck,

Gary

RE: JK2/tomcat 4.1.18 - broken pipe problem

2003-01-02 Thread Jesper Birch

Hi

Thx for the suggestion...

I forgot to write that I have the problem on Solaris 7...

/Jesper Birch


-Original Message-

Even I too got the same problem with configuraion of apache 2.0.40,
tomcat 4.0.4 and  j2sdk1.4.1(sun jvm) on redhat 7.3
 but when I replaced sun jvm with ibm jvm, surprisingly I didn't get
this problem, I am not sure here but what I thought is sun jvm   can't
support green threads on redhat linux but supports only native threads
where as ibm jvm can support green threads on linux machines

Thks,

Hi, 

I have setup a environment with Apache 2.0.43, Tomcat 4.1.18 and JK2
connector. 

Everything seems to work fine, except an error message I get time to
time in my logs:

Can somebody explain for me the condition for when this should happen -
so I can look into this error, or maybe somebody has an idea to what the

You don't.

Java doesn't support Unix sockets, only TCP sockets.  Therefore, Tomcat
only supports TCP sockets as well, unless you write some native code
adapters.

Not much clearer, but I'll try to explain a bit more ;)

It may not be another tomcat thread.  And conversely, it may be a
different (possibly new) instance of your servlet.  Does your servlet
implement SingleThreadModel?

Keep in mind a couple of things:

The amount of allocated memory always increases until it's garbage
collection.  So if you have a run of your servlet, allocating some
memory, and hold on to those objects, they won't be garbage collected.
Then on the next run of your servlet, the VM has no choice but to
allocate more memory.

Tomcat doesn't hold on to these objects.  Make sure nothing in your code
does either.   That way they will be garbage collected.

Have you tried any of the other garbage collection tuning parameters
mentioned in my previous message?   It's worth trying a few runs,
recording your results, and analyzing them.  You can get vastly
different memory profiles with the Java runtime options previously
mentioned.

In 4.1, at least for Tomcat standalone, this is not actually required --
for example, you can add new hosts (and the corresponding contexts)
through the admin webapp and it becomes effective immediately without a
restart.  I don't know how that impacts the web server connectors though
(since I never use them).

RE: Release of memory

2003-01-02 Thread Øyvind Hvamstad

I have to specify that the servlet is done! And the next time the
servlet is run (another tomcat thread) the memory usage starts at the
percentage used by the former run. Say, if I want a report and that
takes up about 50% of memory, and then you want the same. Then you will
take the memory up to 100%, because tomcat still holds 50% from my run,
even though it has terminated!

I don't know if that was any clearer?

Looks like you conmmented out the wrong connector.  The one you have 
removed is identified as the one for port 8009, which is the one Apache 
uses.  Restore that connector and comment out the one that is identified 
as for port 8080.

But when I request a JSP file to Apache, Tomcat doesn't answer, I get this
error:

Is there any way to prevent people from accesing http://mydomain:8080 and
leave AJP 1.3 as the only Connector ?

What you can do:

- Allocate more memory to the heap, using the Java -Xmx parameter.
- Better tune your memory profile by changing the ratio of new
generation to old generation.  Sounds like you're 90% new generation.
See the -XX:MaxNewSize, -XX:NewSize (for JDK 1.3 and before) and also
-XX:NewRatio parameter for JDK 1.4 and later.
- Use a different, e.g. incremental (-Xincgc) or concurrent (on JDK 1.4
and later, -Xconcgc) garbage collector.
- Ensure you don't keep references to object you don't need.  If you
keep strong references, the collecto won't deallocate these objects.

Just create a init-like script that calls the startup.sh using 'su'. The
line would read something like: 'su tomcat -c "/path/to/startup.sh".
Then, you can run the init script as root and, well, use it as an init
script!

how to get meaningful exception in JSP error page

2003-01-02 Thread Brian W. Young

Happy New Year,

I'm using the errorPage="my_own_error.jsp" technique.

However, the "exception" object in my_own_error.jsp gives me the only 
the Jasper stack trace.  It doesn't include info on what part of my own 
code bombed.  I've tried getCause() on exception but it isn't yielding much.

I basically want the bottom most part of the trace that tomcat shows on 
its own interal error page (the one you get before you use the errorPage 
directive)

Thanks for your pointers.
