Re: Problem with including JspC generated web.xml fragment

Actually the semantics is more unclear than the syntax to me. What

webXmlFragment? But in your example the file "generated_web.xml" isn't 
present at first, so there can't anything be added?

mod_jk linking Apache_2.0.52 with Tomcat-5.5.6

[Linda R]

Hi,

I spent all day on this and looked at the Jakarta
documentation as well as this tomcat-user email
archive, but I can not figure this out.

The closest approximation I found was John Turner's
page for Apache 2.0.48 / Tomcat 4.1.29 / mod_jk for
Windows XP.

I'm using (don't laugh) Windows 98.

It automatically generates the mod_jk.conf in Tomcat
but then it doesn't work with JSPs - it only works
with servlets.  It works with the "jsp-examples"
folder, but not if the WEB-INF folder is removed, so I
think it's really using the servlets, not the JSPs. 
It sees nothing in the Tomcat root (webapps/Root)
directory.

If, in Apache's httpd.conf, I insert a paragraph


ServerName localhost
JkMount /*.jsp ajp13
JkMount /servlet/* ajp13
JkMount /*.class ajp13


before the 

Include
"C:\jakarta-tomcat-5.5.6\conf\auto\mod_jk.conf"

line, then the JSPs work, but starting Apache gives
this message:

C:\Apache2\bin 20:04:27.61>apache
[Mon Jan 17 20:17:39 2005] [warn] VirtualHost
localhost:8080 overlaps with VirtualHost
localhost:8080, the first has precedence, perhaps you
need a NameVirtualHost directive

and then some things that would work with the
mod_jk.conf, such as jsp-servlets, a directory outside
the tomcat root directory, don't work.  It doesn't
seem to see the mod_jk.conf.  But this is the only way
I can figure out to get the JSP's or the Tomcat root
directory to work from Apache.

This is so confusing and the Jakarta documentation so
spotty, I'm wondering if it's worth it.

If anyone can clear up these subtleties for me, I
would appreciate it.

Thanks,

Linda

Re: index.jsp: why don't modifications to it show up?

I ran into the same issue a while back and found that there is a
compiled version of the index.jsp in catalina-root.jar file in the /WEB-
INF/lib folder of the root web application.

Hope that helps.

index.jsp: why don't modifications to it show up?

[Kai Utility]

Thanks for your excellent introduction to setting up Tomcat.
I've thought of an addition you might want to include, namely, how to
replace tomcat's index.jsp with one's own.  I'm doing a very limited web
site and wish to expose it to the internet but I don't want the default
tomcat startup page.  Unfortunately, I've found this to be a non-trivial
task that I've spent all day on and still haven't solved.  Below follows
an email I'm sending to tomcat-user@jakarta.apache.org:


I have recently installed tomcat 5.5.4.
I wish to use my own index.jsp in place of the out-of-the-box one.
However, when I make changes to it they don't register.
I.e. I'm making changes to
   $CATALINA_HOME/webapps/ROOT/index.jsp

I have searched this list for "index.jsp" and come up with some
information but I haven't had success yet.  More on that presently. 
This is some of what I've seen so far:

---
http://mail-archives.apache.org/eyebrowse/[EMAIL PROTECTED]&msgId=1735120

When using Tomcat 5.0.25 it seems that any change I make to
ROOT/index.jsp does not show up in the

sort of caching problem so
I've been looking for the compiled JSP in the work directory to delete
it.  Very strange, but it
doesn't seem like this JSP is compiled anywhere.

Does Tomcat 5.0 have some sort of memory resident or log caching that
persists even after the
server is restarted?

http://mail-archives.apache.org/eyebrowse/[EMAIL PROTECTED]&msgNo=150033

Check the webapp's WEB-INF/web.xml -- is said JSP precompiled?

If so, changing the file will (understandably) have no effect: the
container checks its servlet mappings first, files (say, JSPs) second.

---
http://mail-archives.apache.org/eyebrowse/[EMAIL PROTECTED]&msgId=1735455

Good suggestion.  If the JSP is precompiled shouldn't I be able to go to
the work directory and
see index_jsp.class somewhere under a ROOT directory (like there is for
other webapps)?  I guess
one of my basic questions is that why don't I see a ROOT directory in
the work directory?

---
http://mail-archives.apache.org/eyebrowse/[EMAIL PROTECTED]&msgId=1735458

You tell me -- how did you precompile?  

If you're placing classes directly in the "/work" dir, then, yes;
if you're building class files and updating web.xml, then, no.

The former method of precompilation is Tomcat-specific and accounts for
a JSP being updated.  The latter is for production deployments, in which
case the JSPs should not change throughout the release lifetime.

The root context may be under "/work/_" in TC5, but don't quote me on
that.

---
There were some other conversations on this topic but the above seemed
the best.
It seems that the last message above may be pertinent but I don't
understand it.

I found two instances of index_jsp.class in my tomcat tree.
I deleted both and nothing happened.

Solved: Context.xml Resource difference between 5.0.x and 5.5.x?

[TomK]

Solved.Crazy but true.
 
When using the Oracle factory:
In a Tomcat 5.0 context file, the "url" parameter (name, not the value) must be 
lower case.  In a Tomcat 5.5 context file, the "url" parameter must be UPPER 
CASE. 
 
Works now. Thanks for the help.  Sorry for so many mails...

And since Oracle does not use the standard factories that are built into

You need a profiler.  I would suggest JProfiler for development

Help: Context.xml Resource difference between 5.0.x and 5.5.x ?

[TomK]

I'm having trouble moving my webapp from Tomcat 5.0 to 5.5.  The dataSource in 
Context.xml seems to be the issue.
 
According to the 'JNDI how-to' documentation for 5.0 and 5.5, it looks like the 
'' tag has been removed from the Context.xml and instead you 
can now supply arbitrary attributes to the  tag itself.
 
In 5.0, my Context.xml looked like this and it worked fine:


  
  

  factory
  oracle.jdbc.pool.OracleDataSourceFactory


  driverClassName
  oracle.jdbc.driver.OracleDriver


  url
  jdbc:oracle:thin:@xx:xx:xx


  user
  xx


  password
  xx

  

 
...note that oracle's factory requires "user", not "username".

 
Moving to 5.5, I changed it to:
 


  


...this new Context.xml doesn't work.  I get the following:
javax.naming.NamingException: Cannot create resource instance
 at 
org.apache.naming.factory.ResourceFactory.getObjectInstance(ResourceFactory.java:132)
 at javax.naming.spi.NamingManager.getObjectInstance(Unknown Source)
 at org.apache.naming.NamingContext.lookup(NamingContext.java:792)
 
any ideas?  Almost seems as if the "factory" attribute of  is not 
being used.

You've stumbled onto the primary reason I'm not a fan of IDE/container

old-school.

Correct!

Ditto.


: had static fields set they would still be set and accessible via 
: objectclassname.public static string object.getSetting()

Once you fetch the object from the ServletContext, it's like any other
object.  You downcast it to the proper type and go to work.

What makes the ServletContext just a little better than a singleton
(which is another way of making an object globally accessible) is that
there's now loose coupling between the object's class and its access:
client code (other objects) use the ServletContext as the single point
of contact.  If the type of object changes, client code doesn't have to
know...

Java VM Monitor-Debug

[K. Mike Bradley]

I have a need to look inside a running Java VM for a Tomcat app.
We are having problems with an app on every server and can't figure it out.

I have a kernel mode debugger I can use for a Windows app but this is
useless here of course.
What kinds of third party products let you see inside a Java VM?

I need to see processes and threads and execution times and stack and heap
space and whatever else is unique to Java that I need to see.
I mean that I need a real solid diagnostic tool.

I see that J2SE 5 has this monitor API and SNMP as well but I don't think I
can get it in our app.

Is there any third party tools out there that are real solid??

Thanks.

compatible stuff that apache does

 Also you can simply code around this idea or what I read from what is says
to me. What tells you, for example, the OS itslef with enough RAM is not
caching common and recurrent 'events' in memory anyway?

 These stats might be pretty contrived in that sense: 
 ._ "Existing OS designs do not provide graceful management of load" . . .
 ._ "Adopt a structured approach to event-driven concurrency" . . .

 IMHO, these ideas belong more in an application server. Probably you will
find more adepts among the Geronimo project. Good news is that they have
design Geronimo with JMX in mind, so maybe plugging in these ideas will be
pretty easy

Tomcat 4.1.24, Classloader problems

[James Milks]

Hi all,
Having a weird problem that is driving me nuts.

In the past week, every time I update a supporting class (Not a servlet
or JSP) and refresh my page, I get all kinds of null pointer exceptions
and must log out and back into my application or restart Tomcat. This is
a pain in development. FYI - I do have the app set to reload=true.

I looked into the stdout.log file and noticed the following messages:
-
TimeOut
WebAppClassLoader:Lifecycle Error: CL Stopped.
-
Sometimes it appears several dozen times in a row, almost like some sort
of loop is causing the output. A quick restart and everything is ok
again...for a while anyway.

I've not seen this before with Tomcat 4 or 5. 

Any help appreciated.

JW

Ok. Just wanted to be sure as this has been the issue on several posts  
lately.

Now for your problem. There are two (or more) ways that you can deploy  
an application. One is by manual file and folder creation and the  
other is by WAR files. Either way there is a directory structure that  
needs to be followed.

From a recent post:

I think it would be good practice to require your developers to create
war file for you.

Anyway, there is some links that might be useful
http://java.sun.com/j2se/1.4.2/docs/tooldocs/tools.html#basic
look jar-tool, war file is same format that war file.
I think you should read also servlet spefication specks

And maybe it would be worth of use tools like ant

This should get you the information on the structure you need to set  
up. From there you need to create a context.xml file that will solve  
your problem. In 5.5 you do not use the path field unless you put the  
context in the server.xml.

http://jakarta.apache.org/tomcat/tomcat-5.5-doc/config/context.html
gives you several locations to place the context files. If you are not  
using WAR files, then use the "appname".xml

per the above page place it in the  
$CATALINA_HOME/conf/[enginename]/[hostname]/ directory
The path is then taken from the name of the xml file.
OR
context.xml and place it in /META-INF/context.xml inside the  
application files  and the path will be based on the docBase.

If you look there now you will find some files for the built in apps  
(I think) I do not run 5.5 but 5.0 and there are some changes as to  
what was included.

Unless you want it to be the default app, that's in last weeks  
archives.

Re: Servlet static variable not accessible from init() ??

[Jonathan Wilson]

Thanks for responding. I modified the init() method of the servlet to 
redo everything that was being done in the contextInitialized() method 
to workaround the problem. The Listener was getting fired. A while after 
that NetBeans 'ran out of memory' so I restarted it. Now, after 
commenting out the workaround, I am unable to duplicate this problem. 
cblog is always set in the init() method now (like I was expecting). 
I'll leave the workaround code commented out just to see if my problem 
returns later. (Note to self: weird behaviour == restart IDE)

By "store in application scope" you mean: 
getServletContext().setAttribute(string, object) right??
This is then accessible via 
(object)getServletContext().getAttribute(string) and/or if the object 
had static fields set they would still be set and accessible via 
objectclassname.public static string object.getSetting()

Thanks again for responding,

Re: Service Runner question

[Parsons Technical Services]

I do not run Tomcat on Windows. So with that I am making a couple of 
assumptions. If Tomcat is registered as a service, it should be listed in 
the services found under manage on a right click of My Computer. From there 
you can set the service to be manual, automatic or disabled. By setting it 
to manual, you can return there and start it from a right click any time. Or 
you can disable it there and start it from the command line. I also think if 
it is set to manual you will be able to start and stop it with the icons. 
There are others on the list that can correct me here if I am wrong.

So:
Set the service to manual.
Use the start/stop links.

Re: Website downloading old file

[Parsons Technical Services]

Size is also a consideration. Were the two files the same size? Was test1 
smaller?

With ISP proxies, it is a crap shot at how they have them configured.
Test theory:
Upload three files. One smaller, one same size and one large than file.bin.
Download each.
Change each.
Redownload each and check for changes.
Note: You may wish to repeat this test in the event the ISP proxy expires 
the cached item while you are testing. This may also be what happened to the 
test file. Some systems flush the cache at an interval and some do it on 
file age.

Puzzled.
I have a Tomcat 5 application, associated with it a file that can 
be downloaded from the website, which is in the root directory of 
the context. (So if the context is called myapp the file is in 
myapp).

Everything was fine but then I realised that there was a problem 
with the file so I ftped a new file to replace it.
But when I try to download the file from the website it still 
refers to the earlier (larger) file.
This still happens even though I have:
shutdown tomcat,
restarted tomcat,
deleted tomcat work directory,
clerared out my browser cache
used a different browser.

It even still allows the file downloads if I delete the file from 
the server, how can this be ?

Re: Question about JNDI resources

You should be able to store a reference to the Datasource and that should be 
all you need.

Its probably not done that way in the examples since static variables are 
frowned upon. JNDI lookups are usually almost as faster a Hash lookup. So the 
speed is fairly negligible.

Re: Problem with including JspC generated web.xml fragment

Make sure you are building to a scratchpad. This means your web.xml is 
copied to a new location before you precompile. Then JSPC can edit it 
in place and you no not lose any of your changes.

To get around the relative pathing issue - prefix your build with 
${basedir}. For example:

 validateXml="false"
 uriroot="${basedir}/${build.dir}"
 poolingEnabled="false"
 
webXmlFragment="${basedir}/${build.dir}/WEB-INF/generated_web.xml"
 addWebXmlMappings="true"
 outputDir="${basedir}/${jspc.base}"/>

JspC can acually edit web.xml? Where is this documented? I can't find 
any documentation of the jasper2 task except the old outdated jspc task 
(including all the options/attributes) that is included with Ant.

Given that I have the whole web application in a directory called 
webapp, whats the complete jasper2 command to transfor it into a webapp 
with compiled jsps?

With Tomcat 5.x, it's ok, it will just use more memory. With 4.x, it's
bad (one background thread per context = 300 background threads).

- You might have tons of sessions, so increase the VM's memory
- And the usual: one application doing bad things could take the whole

Do you really need one context per customer, or just one datasource
definition per customer?  If you can share, what's the reasoning behind
this?


: 1. What the performance implications are (if any) of having up to 300
: contexts in one container?

Depends mostly on your hardware (memory, CPU, network bandwidth per
host), attitude towards fault-tolerance, etc.

I've been in situations where clients needed to get just a few apps into
the same container, and that created all sorts of headaches: scheduled
downtime (app A and app B need to coordinate); unscheduled downtime (one
rogue app impacts the entire container; one app's bad JNI call takes out
the entire JVM); version skew (one group wants JDK 1.5, the other is
bound to 1.3 or 1.4); and so on.

You'd do yourself a favor to separate the apps into separate machines as
well as separate JVMs.  If a machine goes down, do you want 10 customers
on the phone or 300? ;)


: 2. Are there any scalability issues of which I should be aware?

Same as the first part of my answer to question #1. -that, and
maintenance: will the app itself be the same code, same version, just
installed 300 times?

If both sites/webapps run in the same Tomcat container, look into
the SingleSingOn Valve (that may be a typo, watch out).  That's
Tomcat-specific, though, and it forces you to put both apps in the same
JVM.

Otherwise, you're outside of the scope of the servlet spec.  Look into
writing your own such framework or finding some third-party (free or
otherwise) implementation.

The former would require a fair amount of thought and design if it's
going to be robust.  (Sharing auth info is already a sizable task;
sharing session-like data is another challenge.)  Ask yourself going in
whether it's even worth the work.

For the latter, I haven't seen any such free/open-source products, so
you may end up paying for a commercial app.

Tomcat 5.5.4 and log4j problem

[Yuval Zantkeren]

Hi,

We try to use log4j with Tomcat 5.5.4 on Windows 2003 server and we have 
problems with the rename of the files on rollover.
We try to use DailyRollingFileAppender  and also RollingFileAppender  but both 
with no luck.
Every time the files need to roll we get Log4j:ERROR Failed to rename and the 
files name.

It is very important to us because it logs all of our operation and transaction 
in our website.

I will appreciate any kind of help,

Regards,

Yuval

Re: Tomcat 4 doesn't start http service on Linux?

[Sean M. Duncan]

My first suggestion would be to set up Apache httpd as the load balancer
using mod_jk.  This will give you much more accurate node availability
detection.  This solution also provides much more flexibility when it
comes to using the session tracking API (session affinity, session
replication or both).

If you are running a "stateless" application or are forced to use BigIP
there is a less than ideal node detection scheme available.

I believe BigIP has the capability of pluggable node detection schemes.
You could set up a low overhead resource within your application context
or the root context. BigIP could then run an HTTP Get against that
resource periodically to ensure that the application is still available
on that node.

I'm sure someone could come up with a better pluggable node detection
scheme, but I haven't really given it to much thought since BigIP is
overkill for most situations and there is a scalable, robust and
infinitely cheaper solution available via mod_jk.

If I understand your question, this has nothing to do with iframe vs no
frames, etc: if both resources (URLs) are part of your webapp, then both
will have access to the same session information (though not the same
request-scope or page-scope information).

If the two resources are not part of the same webapp, then no, this

IIRC BigIP and other load balancers confirm a service (application) is
available by periodically making a service-specific request and confirm
the response.  You're running a Tomcat webapp, hence such a
"service-specific request" would be a URL call.

The short version, then, would be to setup a resource -- it
doesn't even have to be a full servlet or JSP, even a plain-text file
containing "I'm Alive" will do -- and put it in a location accessible
via URL.  If the BigIP is able to fetch the document and it finds "I'm
Alive" in it, it flags your application/service as alive and moves on.

If you want to get fancy, make the resource a status page and have BigIP
confirm it sees "OK" in the right spots.

This is true: Tomcat can respond to TCP/IP connections on that port, but
that doesn't mean your app is working as expected.

This doesn't realy make sense...  Are you using Tomcat on its own, or do
you have Apache in front of it?  In the former case, you've enabled the
HTTP connector, and in turn what I described above should solve the
problem.

A Platform for Highly Concurrent Services

[Jean Morissette]

Hi,
I actually contribute to the development of Sandstorm, a Staged 
Event-Driven Architecture (SEDA) based high-performance platform for 
services http://www.eecs.harvard.edu/~mdw/proj/seda/

Our platform is like an operating system for services; it manage 
ressource dynamically and offer optimal performance.

By exemple, we have done a http server prototype that is much more 
performant than the Apache server!

We are actually developping many interesting features and I would be 
happy if some developpers would like to contribute to the project. 
Please, contact me if you are interested.

This does make sense, except for the user part, since users will never access

Furthermore, these long running tasks will be called by a scheduler, off

However, deadlines preclude rearchitecting the solution to make it 
asynchronous as you suggest (it's currently synchronous) in the short term.

I got into this conversation late so forgive me if this has already been

Puzzled.
I have a Tomcat 5 application, associated with it a file that can 
be downloaded from the website, which is in the root directory of 
the context. (So if the context is called myapp the file is in 
myapp).

Everything was fine but then I realised that there was a problem 
with the file so I ftped a new file to replace it.
But when I try to download the file from the website it still 
refers to the earlier (larger) file.
This still happens even though I have:
shutdown tomcat,
restarted tomcat,
deleted tomcat work directory,
clerared out my browser cache
used a different browser.

It even still allows the file downloads if I delete the file from 
the server, how can this be ?

I have the same problem. If you find a solution, please post and email me.
What I found out with my application is that when tomcat runs low on memory,

Re: Website downloading old file

[Ben Souther]

Now, for kicks, try with a file with an '.asp' extension.
Your ISP's proxy server may have a list of extensions that don't get
cached.  This would explain why your dynamic JSPs are working but the
static files are being cached.

Re: Website downloading old file

[Paul Taylor]

OK I think you are onto something here,
the original file was called file.bin, new file replacing it also called 
file.bin and renamed to file2.bin

When I use the ?var=bogus the correct file is returned, but when I don't 
specify a parameter for file.bin it still returns the older file.

http://domain/context/file.bin  INCORRECT OLD 
VERSION
http://domain/context/file.bin?var=bogusOKNEW VERSION
http://domain/context/file2.bin?var=bogus  OK NEW VERSION

Two ther bits of info which maybe relevent.
1. The host is based in Canada and hence has time set to Candian time 
which is earlier than UK time where Im downloading to.
2. The file Im trying to download is a .bin (Linux) file.

The problem is also happening on Internet Explorer.

Subject: Website downloading old file


   

Puzzled.
I have a Tomcat 5 application, associated with it a file that can 
be downloaded from the website, which is in the root directory of 
the context. (So if the context is called myapp the file is in 
myapp).

Everything was fine but then I realised that there was a problem 
with the file so I ftped a new file to replace it.
But when I try to download the file from the website it still 
refers to the earlier (larger) file.
This still happens even though I have:
shutdown tomcat,
restarted tomcat,
deleted tomcat work directory,
clerared out my browser cache
used a different browser.

It even still allows the file downloads if I delete the file from 
the server, how can this be ?

Re: precompilation trouble

[Tim Funk]

Oops, my bad. Forget newInstance() being called. But the line:
Class bean = ctxt.getClassLoader().loadClass(klass);
I believe does force my previous static statements to hold true.

At compile time - jasper is checking that the default constructor of a

Hmm, were is that code is an invokation of a constructor? As far as I

Question about JNDI resources

[Alan Deikman]

I'm just learning this stuff, but having good success so far.  In my
SQL-backed bean I use a JDBCResource as per the documentation:
protected static Connection getConnection() {
   //System.out.println("User.getConnection Attempting to get
connection");
   try {
   Context initContext = new InitialContext();
   Context envContext  =
(Context)initContext.lookup("java:/comp/env");
   DataSource ds = (DataSource) envContext.lookup("jdbc/");
   Connection conn = ds.getConnection();
   return conn;
   } catch (NamingException ne) {
   System.out.println("User.getConnection caught Naming
exception");
   System.out.println(ne.toString());
   } catch (SQLException sqle) {
   System.out.println("User.getConnection caught SQL exception");
   System.out.println(sqle.toString());
   }
This works, way cool.  My question is do I need to look up two new
Context objects and a new DataSource each time I get a connection?  Or
can I just store initContext, envContext, and ds in static variables and
load them just once for all instances of the class?
If that works, why don't the examples do it that way?

question on session info in manager webapp

[Stephen Charles Huey]

When I go to /manager/html and then click on the session count for one
of my webapps, it displays this:

OK - Session information for application at context path /testwebapp
Default maximum session inactive interval 30 minutes
120 - <130 minutes:4 sessions

If the default timeout is set to 30 minutes, why does it say 120 - <130
minutes?  When I look at other examples online where the default timeout
is set to 30 minutes, the 3rd line on those examples says 30 - <40
minutes.  So what does this mean?  That 4 sessions have been created in
the last couple of hours?  Why does it show it for a whole 2 hours
instead of just for the last half hour or whatever?  

Thanks,
Stephen

These requests are not going to be called by users through a browser, since 
they are "Web Services/REST" types of requests.  The only time they might get 
called through a browser is for testing purposes, in which case the tester 
knows that they will be very long running and that's not at issue.

The timeout seems to be affecting scripted invocations of the request as well 
(using the commons-http library), so it doesn't seem to be a browser timeout 
issue as far as I can tell.

This does make sense, except for the user part, since users will never access 
the URL's involved directly.

Furthermore, these long running tasks will be called by a scheduler, off 
hours, and typically there will be very few such requests a day (maybe 2 or 3 
max).  The requests are really single overnight batch processing runs.

However, deadlines preclude rearchitecting the solution to make it 
asynchronous as you suggest (it's currently synchronous) in the short term.  

Hence my looking for a way to easily fix the timeout issue that causes the 
response to be truncated when Tomcat services a long running request.

Thanks for the inputmost appreciated.

Re: Problem with including JspC generated web.xml fragment

[Andreas Schildbach]

Tim Funk wrote:
Odd, I do not have this problem.
Make sure you are building to a scratchpad. This means your web.xml is 
copied to a new location before you precompile. Then JSPC can edit it in 
place and you no not lose any of your changes.

To get around the relative pathing issue - prefix your build with 
${basedir}. For example:

 validateXml="false"
 uriroot="${basedir}/${build.dir}"
 poolingEnabled="false"
 webXmlFragment="${basedir}/${build.dir}/WEB-INF/generated_web.xml"
 addWebXmlMappings="true"
 outputDir="${basedir}/${jspc.base}"/>
JspC can acually edit web.xml? Where is this documented? I can't find 
any documentation of the jasper2 task except the old outdated jspc task 
(including all the options/attributes) that is included with Ant.

Given that I have the whole web application in a directory called 
webapp, whats the complete jasper2 command to transfor it into a webapp 
with compiled jsps?

Re: Website downloading old file

[Paul Taylor]

What is going on ?
I moved the file to a new filename and edited the jsp to point to the 
renamed file. Tried to download it and it downloaded as the correct size.
I then mnoved it back to the oldfilename and changed the jsp back to 
point to original filename and once again it downloads the old larger 
file which no longer exists !

Two ther bits of info which maybe relevent.
1. The host is based in Canada and hence has time set to Candian time 
which is earlier than UK time where Im downloading to.
2. The file Im trying to download is a .bin (Linux) file.

Puzzled.
I have a Tomcat 5 application, associated with it a file that can 
be downloaded from the website, which is in the root directory of 
the context. (So if the context is called myapp the file is in 
myapp).

Everything was fine but then I realised that there was a problem 
with the file so I ftped a new file to replace it.
But when I try to download the file from the website it still 
refers to the earlier (larger) file.
This still happens even though I have:
shutdown tomcat,
restarted tomcat,
deleted tomcat work directory,
clerared out my browser cache
used a different browser.

It even still allows the file downloads if I delete the file from 
the server, how can this be ?

RE: Still having OutOfMemory Problems (Tomcat 4.1.31)

[Larry Isaacs]

David,

"-D" defines System properties, "-X" defines vendor specific JVM options.
Thus, "-DXms128M" is incorrect.  It should be just "-Xms128M".  Same for
the other "-DX" arguments.

Cheers,
Larry

RE: Still having OutOfMemory Problems (Tomcat 4.1.31)

[David Vandaele]

Try printing out this:
Runtime.getRuntime().freeMemory():
Runtime.getRuntime().maxMemory();

Check out the API if you want to know the exact meaning of these methods, but 
they are pretty obvious I think.
Now print these somewhere you know you'll get before the OutOfMemError occurs, 
or some place like the service() method or something.

Tomcat 4.1.31 Out of Memory Follow up

[David Johnson]

Hi again

I've searched through the registry as well, and at
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Apache Tomcat
4.1.31\Parameters it DOES show the -Xmx=512M and -Xms=128M that are
set in my installService.bat.

It does not, however seem to be actually USING that much memory.

Is there a way to easily verify how much it's using?

Tomcat 4 doesn't start http service on Linux?

[Stephen Charles Huey]

We just installed Tomcat 4 on 2 Red Hat servers, and we have a BigIP
load balancer in front of them.  In troubleshooting an issue, the guy
working with our BigIP said that when he was running Apache on either of
the Linux servers, the load balancer could tell that the http service
was running, but when Tomcat was running, it didn't know what to check
for on a service level, so in the end, they had to set it up to just do
a TCP check to see if the port was open.  

He says this isn't ideal since the port being open doesn't mean the
service is up (meaning Tomcat).  He thinks that Tomcat should start up
the http service (I guess he means httpd) when it starts--that maybe I
just need to look around in Tomcat's configuration for the place to set
this, but I'm not so sure that this is the case.  

In a nutshell:  is Tomcat supposed to start up the http service or
something similar to what BigIP is looking for from Apache?  

Thanks...

Developing a large project using Tomcat, please help me

[GPezzini]

Hi,
we are developing a large java project using Tomcat.
On the same project works several persons and the project counts
serveral thousand of classes.

The project has (in few words) three big places:
- standard: the place in which are placed all the classes (not jar but
classes)
- patches: the places in which are places the bug-fixes of standard classes
- work in progress: the place in which a developer develop his own
modification to a standard class

Each developer has its own Tomcat.

Now, imagine that
- in standard classes is there a class named: helpme.class
- this class has been bug-fixed and in  patches is there the same class
- a developer is working on its own local copy of this class and he has
  places it in his own work-in-progress folder

Is possible using Tomcat to manage a situation like that?
In other word, If I develop using j2SE standard, to obtaint what i want,  I
simply set my CLASSPATH
env variable in this way;

set
CLASSPATH=x:\MyWorkInProgress\classes;x:\AllPatches\classes;x:\Standard\classes


And java default classpath ensure me that it loads helpme.class first
looking in WowkInProgress,
than, if not found, in AllPatches, than, if not found in standard

Is it possible during Tomcat runtime to have something like that (possibly
WITHOUT using jar)

Thank you very much in advance.

Sounds like your ISP may have a proxy setup. Usually two different browsers

Puzzled.
I have a Tomcat 5 application, associated with it a file that can be 
downloaded from the website, which is in the root directory of the 
context. (So if the context is called myapp the file is in myapp).

Everything was fine but then I realised that there was a problem with 
the file so I ftped a new file to replace it.
But when I try to download the file from the website it still refers to 
the earlier (larger) file.
This still happens even though I have:
shutdown tomcat,
restarted tomcat,
deleted tomcat work directory,
clerared out my browser cache
used a different browser.

It even still allows the file downloads if I delete the file from the 
server, how can this be ?

Re: multiple ips, multiple ssl certificates and port forwarding

[Parsons Technical Services]

Tomcat needs the name of the keystore to be .keystore
No it doesn't. The name (and path) is arbitrary, which is why
there *is* a keystoreFile attribute.
As I said before, I haven't done this myself.
I have, and none of my installations use ".keystore" as the file
name...

That is why I made the statement. Thanks for correcting me on that. Now I

Re: Problem with including JspC generated web.xml fragment

[Tim Funk]

Odd, I do not have this problem.
Make sure you are building to a scratchpad. This means your web.xml is copied 
to a new location before you precompile. Then JSPC can edit it in place and 
you no not lose any of your changes.

To get around the relative pathing issue - prefix your build with ${basedir}. 
For example:

 validateXml="false"
 uriroot="${basedir}/${build.dir}"
 poolingEnabled="false"
 webXmlFragment="${basedir}/${build.dir}/WEB-INF/generated_web.xml"
 addWebXmlMappings="true"
 outputDir="${basedir}/${jspc.base}"/>

Where / How to place app config file without overwriting during deploy

[Jonathan Wilson]

My current upgrade procedures are to shutdown tomcat 3.x, move the 
current version of my webapp directory somewhere else, recreate the 
/webapp directory, then un-jar the war file created by NetBeans. After 
doing this I then have to modify the WEB-INF/app.config file with 
customer-specific information. The code is identical, just configuration 
items change. If the customer has changed their app.config then I have 
to roll those changes into the new app.config file. Also, I have to copy 
the log files out of the old version into the new versions' /logs 
directory and modify the stock log4j.properties to point to their 
desired directory. Also, I can't always have access to the server to do 
this so I've written a procedure to explain this to another.

Is there a way to store customer configuration info(app.config, 
log4j.properties) outside of the app and have the app still know how to 
find it?

There must be a better way - nothing in the Tomcat Application 
Developers Guide that covers this.

Thanks in advance,
JW

AW: Long running requests and timeouts?

[Bernhard Slominski]

Hi Andrzej,

one possible workaround is compress the output, so the response is
compressed with zip compresseion and your response gets shorter.
You need a response filter for that, if this is an option an you need more
details let me know.

Cheers

Betreff: Long running requests and timeouts?


I have a situation where some requests that get sent to Tomcat are very long

running (basically batch operations).  I've been testing with a request that

takes just over 7 minutes to process and returns and XML document as a 
response.

The problem I'm having is that the response gets truncated.  It's always 
truncated at a consistent spot (3207 characters for some reason, that's what

Firefox reports).

Shorter running requests don't truncate anything, regardless of how long the

response might be.

I'm running Tomcat 5.0.28 and my Connector in the Tomcat server.xml file 
looks like:



Is the connectionTimeout value the one that might be contributing to this 
behaviour?

Are there any other timeout settings that might affect this?

Ouch! Are you sure your tomcat installtion is OK? You could have a version

reason why tomcat can't find this class. This is not an XML issue, this is a
class loading problem.

Re: Long running requests and timeouts?

[Frank W. Zammetti]

I can't answer your specific question, but the scenario you describe 
raises a red flag with me in general...

When you potentially have such long-running requests, it's usual a Bad 
Idea(tm) to just allow them to run like this as part of a request.  I 
think it's fair to say that most people would say you should be taking 
some sort of queueing or multithread approach, coupled with polling.

I don't know your usage pattern, but especially if there could be a 
number of such requests coming in at once, you are tieing up server 
resources this way.  You also start running into situations like you 
mention with timeouts (I'm actually surprised the browser itself didn't 
time out after a few minutes).  It also doesn't give a very good 
appearance to the user... it seems like the system has just frozen, 
which it actually hasn't.

If it's feasible, I think you may save yourself some trouble by 
rearchitecting this rather than trying to solve this problem.  You can 
do something as simple as this...

(1) Have a class with two static HashMaps.  One HashMap we'll call 
THREADS and it will store a reference to an object (more on this in a 
second), keyed by userID... In the other that we'll call STATUS you will 
store a Boolean, also keyed by userID.
(2) When one of these long-running requests comes in, spawn a thread to 
handle the XML generation, and put a reference to the thread in that 
THREADS HashMap for the userID your servicing (might want to use 
sessionID instead, it's up to you)... In the STATUS HashMap, store a 
false Boolean (false means the request hasn't completed yet).
(3) Return a "Plase Wait" page to the user.  Use a simple JavaScript 
timeout to call a status checking function every few seconds that checks 
the value of the Boolean.  If false, just return that Please Wait page 
again.
(4) When the thread completes, it should set that Boolean to true for 
that userID.
(5) When the status checking function finds True, it should (a) get the 
reference to the thread from the THREADS HashMap, (b) get the XML from 
the thread (just store it in a class-level variable and expose it with a 
getter), (b) set some value in the thread object that indicates the 
thread should die, (c) return the XML to the browser.

Does that all make sense?  I don't know if your in a position to 
rearchitect what your doing, but if you are, I very much suggest doing 
so.  Hope this helps!

Re: precompilation trouble

[Tim Funk]

Ahh. Here is your issue:
if (beanName == null) {
try {
Class bean = ctxt.getClassLoader().loadClass(klass);
int modifiers = bean.getModifiers();
if (!Modifier.isPublic(modifiers) ||
Modifier.isInterface(modifiers) ||
Modifier.isAbstract(modifiers)) {
throw new Exception("Invalid bean class modifier");
}
// Check that there is a 0 arg constructor
bean.getConstructor(new Class[] {});
generateNew = true;
} catch (Exception e) {
// Cannot instantiate the specified class
if (ctxt.getOptions().getErrorOnUseBeanInvalidClassAttribute()) {
err.jspError(n, "jsp.error.invalid.bean", klass);
}
}
}
At compile time - jasper is checking that the default constructor of a bean 
may be invoked. By invoking the constructor at compile time - the class is 
loaded by the JVM. This will in turn cause the JVM to call any static 
initializers. (In which you have)

I see :-)
=== description ===
I am using the ant script I found on page
. The 
relevant software I use is Tomcat 5.0.26 (the one that comes with JBoss 
3.2.5) and JSF 1.1_01 reference implementation (the latest release).

BTW: Is there a way to let Tomcat do the job of JSP compilation on 
deployment? I mean without the need of visiting each page manually?

One more thing you might want to consider: The web app was working fine until 
the server admin did an upgrade on the cpanel app that's what started this 
all...

Re: multiple ips, multiple ssl certificates and port forwarding

[Parsons Technical Services]

I think you have an error in your server.xml. The path to the keystore and 
other SSL fields are in the Factory element instead of the connector 
element.



   port="8443" minProcessors="5" maxProcessors="30"
   address="100.100.100.3"
   enableLookups="true"
   acceptCount="30" debug="0" scheme="https" secure="true"
   useURIValidationHack="false" disableUploadTimeout="true">
  
   keystoreFile="/home/essence/essence/KEYS/c.keystore"
   keystorePass="xxx"
   clientAuth="false" protocol="TLS" />



Should read:


   port="8443" minProcessors="5" maxProcessors="30"
   address="100.100.100.3"
   enableLookups="true"
   acceptCount="30" debug="0" scheme="https" secure="true"

web.xml parsing error SEVERE

Dear subscribers,

I am having a strange problem starting tomcat.
Catalina.out says I have an error at the closing tag 

Any clue on what the problem might be?

Your comments will be most appreciated.

Long running requests and timeouts?

[Andrzej Jan Taramina]

I have a situation where some requests that get sent to Tomcat are very long 
running (basically batch operations).  I've been testing with a request that 
takes just over 7 minutes to process and returns and XML document as a 
response.

The problem I'm having is that the response gets truncated.  It's always 
truncated at a consistent spot (3207 characters for some reason, that's what 
Firefox reports).

Shorter running requests don't truncate anything, regardless of how long the 
response might be.

I'm running Tomcat 5.0.28 and my Connector in the Tomcat server.xml file 
looks like:



Is the connectionTimeout value the one that might be contributing to this 
behaviour?

Are there any other timeout settings that might affect this?

Thanks!

I see :-)

I am using the ant script I found on page
. The 
relevant software I use is Tomcat 5.0.26 (the one that comes with JBoss 
3.2.5) and JSF 1.1_01 reference implementation (the latest release).

BTW: Is there a way to let Tomcat do the job of JSP compilation on 
deployment? I mean without the need of visiting each page manually?

Problems like this are much easier to resolve when we can all see your
web.xml.  =)

Sounds like a typo.

RE: Charater limit in servlet names

[Allistair Crossley]

hi, 

this will be something else like a servlet-mapping problem, don't forget you 
change the servlet-name in both the servlet definintion and the servlet-mapping 
also.
