date:20041014

We are going to run a test this evening with an application that
someone else wrote other than our own developers to see if the problem
still exists. When the problem occurs we hit 100% cpu util with jsvc
(tomcat deamon) taking all of the cpu. Also we switched back to the
standard collector with 128 mb min / 256 mb max which resolves the out
of memory problem, but we still have the pauses every so often. We
have watched Visualgc and went through the jvmstat logs that showed us
that new and old gen had plenty of memory when the problem exibited
itself. We didn't have any gc for a period of time before and after
the problem occured.

Again thanks for all of the help and suggestions.

Thanks to Larry and Yoav.
I'm sorry that I didn't search hard enough(TC FAQ. duh!) and asked such 
a simple question. :)

I'm evaluating TC 5.0 on Windows XP, coming from TC 3.3.1 on RH7.3.
I can't get TC 5.0 to recognize any beans I put in the WEB-INF/classes
directory(windows perms all good). If I put the bean into a package and
create the proper subdirectory under WEB-INF/classes/ it sees the bean.
I don't have to use a package in TC3.3.1 - is this something new or ???

RE: Tomcat 5 pause (free gmail account for fix :-)

2004-10-14 Thread Dale, Matt


My next line of attack would be at the application itself. Is it possible that the 
application is locking somewhere or is poorly threaded in some respect?

What does top say when the cpu spikes? ie what is the load? what is the top process?

If you experienced out of memory errors before you used the incremental collector have 
you tried switching back to the standard collector but increasing the Xmx setting to 
what is required by the app so as not to experience out of memory exceptions.

Matt,
We have used jvmstat/visualgc which is how we found out that the
problem happens at times when no gc is taking place. We are actually
logging every second with jvmstat everyday at this point. The problem
we are stuck at now is trying to figure out how to get more infomation
out of the jvm when we can't catch the problem with a profiler and
can't run verbose gc for a long period of time.

Under most instances, but not all.  For example, if the library you're
using the find the list of printers is in common/lib or shared/lib, your
thought above is false.

Re: Tomcat 5 pause (free gmail account for fix :-)

Nope not swapping. Based on what we see in jvmstat/visualgc we
typically have 64mb of  data in old gen, 12mb of app data, and about
12 mb of new gen data. The OS still has free memory as well.

Please post the servlet, or provide a walk-through.
It really sounds like you're storing data somewhere (instance variable,

RE: Servlet caching?

Hi Tim,
I have found that even if I terminate every connection of the servlet to the
database and reload the servlet, the servlet still does not find the newly
installed printer.  I would think that after reloading the servlet all the
classes that it had used would cease to exist.  That is, any class that had
been instantiated or used by the servlet would not remain instantiated after
I reload the servlet.

So I am thinking that re-starting tomcat somehow makes Tomcat aware of the
services that have been installed after Tomcat was started

Hi,
The servlets by themselves do what you tell them to: you wrote them,
after all ;)  Tomcat doesn't provide any caching of response content by
itself without special effort or configuration on your behalf.  As Tim
said, my guess is a utility class used by your servlet is doing the
caching for the printer services list.

RE: Tomcat 5 pause (free gmail account for fix :-)

2004-10-14 Thread Dale, Matt

I reckon this still might be a garbage collection problem.

I would download jvmstat from sun and use visualgc to monitor this. It gives a good 
graphical representation of when the box is garbage collecting and how much stuff is 
in each of the generations.

We had a similar situation and this arose because the app created lots of very short 
lived objects. Increasing the young generation size alleviated this problem and also 
reducing tenuring so medium term objects made it to the old generation.

There are also a few more garbage collection parameters you can play with. If you have 
multiple processors you could try enabling the parallel collector. There is also the 
Concurrent Mark Sweep collector which locks the JVM only in a small part of it's 
collection. You could try using the aggressive heap settings which will try to use all 
the memory in the machine that it can.

I think more visibility of your garbage collection cycles is the first port of call in 
any event.

Hi

I assume you cannot prove that, right?

Regards,
  Steffen


smime.p7s
Description: S/MIME cryptographic signature

RE: mod_jk2 Ready/Recommended For Production?

On a somewhat related note;

Anyone have best practices/recommendations on handling traditional
.htaccess control on content?

I don't particularly care to have the 2 separate layers of security,
purely from an ease of administration perspective.
.htaccess controls are totally bypassed when requesting content handled
by Tomcat.
For example, simply clicking cancel during the authentication dialog box
will still present the default index.jsp page, or ignored all together
if requesting the .jsp directly.

In addition to creating the .htaccess, you then must also create your
Tomcat Security Realm.

Is there anyway to have Apache & Tomcat use the same user/pass file?
Can a Realm be created that is simply;
username:MD5 encrypted password (such as the format of .htaccess)

I'd rather not have to go to the extent of creating user/password pairs
in a database, then setting up something like mod_auth_mysql and JDBC
for centralized authentication (is this even possible?).

I have been using mod_jk2 for a couple of years now, and I have not had
to
compile it, either.  I use it on Linux production systems... (currently
I
am using Redhat Enterprise Linux and the Fedora binary).

The biggest problem has always been extremely poor documentation.
However, the Fedora download has a directory structure that quickly
shows
you where to place the needed files.  I was setup in less than 30
seconds.

I am a big fan of a 3-tier architecture.  I think it's important to have
web requests intercepted on one layer, and only handed off to the
processing layer (tomcat) when need be.  Apache is likely much better
than
tomcat in serving static content, and even though tomcat has lots of
security, I feel much more comfortable with Apache being at the front
door, because of its extremely wide use and history.

Re: Tomcat 5 pause (free gmail account for fix :-)

2004-10-14 Thread Jonathan Wilson

I have a similar problem(TC 3.3.1) but it is related to our pooling
solution running out of connections and/or it trying to reap
not-checked-in connections. The lockups users reported were during a
reap cycle. After a few seconds up to a minute(sound familiar) it would
"go away" and the app would start servicing requests again(checkout
"netstat -a" and count your connections before and after your hicup). It
only happens when someone "hits" the place where I didn't checkin enough
times to deplete the pool. I'm feverishly trying to finish
implementation so as a bandaid I've increased my pools depth to 100
connections for alpha testing...working for now.

Question: Anyone have any ideas on how to track what/where a checkout
doesn't get checked-in(better pooling solution? I'm using bitmechanic
now). What benefits does TC 4/5 built-in pooling mechanism have over my
current solution?

Also, when my TC ran out of memory(out of Resources Exception) I just
increased the Heap size using TOMCAT_OPTS="$TOMCAT_OPTS -Xmx300m" placed
in the tomcat.sh script(TC 3.3.1 remember) and it's never happened
again(no object loitering, just lots of objects!). If you grow too
large(and/or never stop growing!) I'd look into indirectly referenced
objects..here's a link to an article about this behavior(good
performance analysis info):

It still may be some sort of GC activity.  A profiler will show you
exactly what's going on, and (better still) whether it's a particular
type of object or place of object creation that's causing a GC spike.

Be sure to give the profiler the Gmail invite. ;)

RE: Tomcat 5 pause (free gmail account for fix :-)

Are you defining any Memory Min/Max (-Xms/-Xmx) constraints on the JVM?
Are you collecting any verbose GC information (-verbose:gc)? 

How much physical memory available on the machine?

At times of 100% CPU Utilization, is it java that is consumnig the
majority of it?

Everyone,
Thanks in advance for any help. Also I have a gmail invite for the
person who has a fix for this if they are interested.

My company has been using Tomcat for several years, but a problem has
crept up that we have not been able to solve. Basically, tomcat will
stop processing requests for 2-60 second period several times a day.

Here is a list of software that we have tried. (Note we have tried
changing each key componant to see if we isolate the componant that is
the problem, but no luck yet)

OS: RedHat 9 & AS3
Threading model: linux threads & nptl
JVM: sun 1.4.2_4 & latest ibm
Http connector: ajp w/apache 2 and coyote connector
JBDC connector 1.0


1. Doesn't always happen durning old gen garbage collection, but does
sometimes
2. Before switching to incremental gc we received out of memory errors
which resulted in Tomcat completly hanging
3. After switching to incremental gc the effect changed to 2-60 second
periods of time that Tomcat won't process request, but it does resume
on its' own.
4. Cpu usage for most of the day is less than 20% utiliztion, but when
the problem occurs the cpu spikes to 100% utiliztion briefly.

mod_jk2 MaxPocessors... what happens when limit is reached?

2004-10-14 Thread raiden

Hello,

We have two Apache instances talking to one tomcat instance.  The two
Apache instances have 200 MaxClients each... so 400 total.  I assume this
means that the tomcat instance should be set for 400 MaxProcessors?

If we set it for lower, what happens with mod_jk2 when the MaxProcessor
limit is reached?  Do Apache connections wait for a turn, or is an error
immediately returned?  (With the older mod_jk, an error was returned...
which is pretty undesirable.)

Thank you,
-Raiden Johnson

RE: mod_jk2 Ready/Recommended For Production?

2004-10-14 Thread raiden

I have been using mod_jk2 for a couple of years now, and I have not had to
compile it, either.  I use it on Linux production systems... (currently I
am using Redhat Enterprise Linux and the Fedora binary).

The biggest problem has always been extremely poor documentation.
However, the Fedora download has a directory structure that quickly shows
you where to place the needed files.  I was setup in less than 30 seconds.

I am a big fan of a 3-tier architecture.  I think it's important to have
web requests intercepted on one layer, and only handed off to the
processing layer (tomcat) when need be.  Apache is likely much better than
tomcat in serving static content, and even though tomcat has lots of
security, I feel much more comfortable with Apache being at the front
door, because of its extremely wide use and history.

Tomcat 5 pause (free gmail account for fix :-)

Everyone,
Thanks in advance for any help. Also I have a gmail invite for the
person who has a fix for this if they are interested.

My company has been using Tomcat for several years, but a problem has
crept up that we have not been able to solve. Basically, tomcat will
stop processing requests for 2-60 second period several times a day.

Here is a list of software that we have tried. (Note we have tried
changing each key componant to see if we isolate the componant that is
the problem, but no luck yet)

JBDC connector 1.0

3. After switching to incremental gc the effect changed to 2-60 second

Yes, and that person's me! :) I just sent a test WAR that demonstrates the

RE: Help with mod_jk2

Hello,

Using jkUriSet I get this now:
[Thu Oct 14 10:57:32 2004] [notice] uriEnv.setAttribute() the worker
directive is deprecated. Use 'group' instead.

(I removed all the uri mapping for that instance in workers2)

And tomcat isnt getting routed to port 80.

Any ideas?

RE: disable "Restart Persistence" using the standard Manager implementation


Hi,
Case is significant.  It's  not .

As to whether a Manager is included by default or not: I'll amend my
previous statement to say *most* (not all) Tomcat versions in the past
did include one in server.xml by default.

I'm setting it up so that I can have multiple instances of tomcat running and 
I don't want many different copies of the files floating around if at all 
possible.  It also makes it easy for me to perform upgrades on tomcat etc. 
when I use symlinks to some of the files (app specific) that don't change.

This has nothing to do with physical memory.  The maximum heap size is
dependent on the largest contiguous virtual space available in the 2GB
that Windows provides for each user process.  Unfortunately, this space
is fragmented by various DLLs that Windows preloads for you, so the
biggest chunk you can use is noticeably smaller.  I suspect the recently
applied updates reduced this largest contiguous area, resulting in JVM
initialization errors.  You'll need to experiment with -Xmx to find the
largest value that works in your current environment.

Re: Sun J2SE JVM + tomcat + Debian??

Yeah, I'm using -server.  I tried kernel 2.4.27 on the debian box and 
that actually works.  If I get a chance I'll try it w/o -server on 2.6.7 
but for now I'm happy that I don't have to switch distros just to run Java.

We've tried all four combinations of j2se 1.4.2, j2se 1.5, tomcat4 and

When Tomcat ships, a Manager is in server.xml by default.  Did you
remove it?

>Is this mean that i HAVE to set this element?

Yes, as with all other elements, if you want non-default behavior you
must specify it.  That's the meaning of "default" ;)

>And if so, how do i achieve the default behavior?

Either grab a fresh server.xml from a Tomcat distro, or look at the
Manager docs page and declare one with the default attribute values.

Maybe if you're more careful about your quoting ;)  But yes, that's
pretty close.

Hi,

I do not have a manager element in my server.xml. 
Thus, i use the default manager setting. 
Is this mean that i HAVE to set this element? 
And if so, how do i achieve the default behavior?
I.e.
will this configuration do the work?

RE: MySQL driver randomly not found?

Hahah, similar reasoning wth my symlink question...shouldn't matter,
but...

Hi,
It might not, but it's always a question, because it's part of the KISS
principle.  The simpler the environment, the easier it is for the OP to
test and for others to reproduce the OP's test results.  The less moving
pieces, the less chance for error.

RE: disable "Restart Persistence" using the standard Manager implementation


Hi,
Try setting pathname="" in the Manager declaration in server.xml.  You
could also try setting an invalid pathname.

Porting a servlet app to ASP.NET?

2004-10-14 Thread Steve Kirk


A customer is interested in licensing and developing the source code for a
servlet-based webapp that I am writing, but for maintenance and support
reasons they want it written in MS technologies (asp, asp.net, c#, etc)
rather than Java servlets.  I have some experience of webapps written in ASP
from about 2-3 years ago, but don't know much about the newer MS stuff such
as asp.net or C#, so am not sure how big a task this might be.

Can anyone comment on how similar the MS code might be compared to my
servlet code, and how easy it would be to re-write a servlet 2.4 app using
the MS technologies?

Are there any tools that can "translate" servlet/JSP code to asp.net
equivalent?  I have seen this, which appears to do the opposite:
http://www.netcoole.com/j-asp.htm

I have read a MS article here
http://www.microsoft.com/resources/casestudies/CaseStudy.asp?CaseStudyID=158
64 
which appears to suggest that servlet code can be used with relatively few
changes and recompiled under J# then run under ASP.net - I'm more than a
little sceptical about this - can anyone with experience of j# comment on
that?

disable "Restart Persistence" using the standard Manager implementation

2004-10-14 Thread Sun House

Hi all,
I use TC 5.27.
I have a server.xml cofigured without Manager element configured - thus according to 
documentation, tomcat run, using it's standard manager implementation.
 
Also, according to documentation whenver Catalina is shut down normally and restarted, 
or when an application reload is triggered, the standard Manager implementation will 
attempt to serialize all currently active sessions.
 
I wish to disable that.  or to be more precise, i wish to disable deserialize of 
serialized object, on server restart. this is because i have un serialized objects on 
session, which i do not wish to serialize.
 
currently i get "SEVERE: IOException while loading persisted sessions"  when ever i 
restart the server, and i wish to get rid of it.
 
is there a way to do that?
 
thanks in advance
Sun House

Thank you for pointing out these redundant attributes.  I applied these changes

server can't compile some jsp.

Очень нужна помощь !

I have no problems with application working on my computer.
But, on the customers computer I am facing the problems
with the same application. Some pages are compiled, and some not.

Re: context file

2004-10-14 Thread kax

I solved the problem.
I was ok to put the context file in tomcat before the war file as long as
you deployed the context file and war file together like this:

http://localhost:8080/manager/deploy?config=file:/path/context.xml&war=jar:file:/path/bar.war!/

I'd be happy to send it to you if it was mine to send, but it belongs to my

Some random stuff:

Only use either antiJARLocking or antiResourceLocking. Never both.

Also, on your Context element, remove debug, path, and docBase, which
are either gone, or are rundundant data.

Re: How to redirect http to https automatically?

2004-10-14 Thread David Wall

This is part of the servlet specs.  In  your WEB-INF/web.xml file, you need
a security constraint that says the site should be secure, something like:


  
Entire site
/*
GET
POST
  
  
CONFIDENTIAL
  


The "confidential" keyword ensures that the webapp will require https, so if
you try to get it via http, then the redirect stuff specifed in your
server.xml will be applied.

This has nothing to do with physical memory.  The maximum heap size is dependent on 
the largest contiguous virtual space available in the 2GB that Windows provides for 
each user process.  Unfortunately, this space is fragmented by various DLLs that 
Windows preloads for you, so the biggest chunk you can use is noticeably smaller.  I 
suspect the recently applied updates reduced this largest contiguous area, resulting 
in JVM initialization errors.  You'll need to experiment with -Xmx to find the largest 
value that works in your current environment.

RE: administration webapp

2004-10-14 Thread Michael Simpson

Hi James.

This is from the Digest documentation:

"The value for this attribute must be one of the digest algorithms supported
by the java.security.MessageDigest class (SHA, MD2, or MD5)."

Tried it with MD5 and the digest param commented out - no joy.

Yoav: bear with me, but how would I check the environment variable?

Thanks.

In server.xml, I'm not exactly sure what MD2 is.  I know what MD5 is,
and it's clear that your passwords in tomcat-users.xml are clear text.

Try removing digest= from Realm and restart.

Subject: administration webapp 

Hello list.

Just joined the list and I'm very new to Tomcat.

I have a problem accessing the administration webapp and manager webapp
links from the default Tomcat home page.
The following is listed on the home page:

NOTE: For security reasons, using the administration webapp is
restricted to
users with role "admin". The manager webapp is restricted to users with
role
"manager". Users are defined in $CATALINA_HOME/conf/tomcat-users.xml.

This is the code from tomcat_users.xml :


  
  
  
  
  
  


And this is a snippet from server.xml :


I've looked at the manuals, etc. but it just does not seem to work -
access
always fails.
Can anyone see the obvious mistake here.
Thanks in advance.

Hi,

Y.jar) .
>Can this be achieved ?

Only be putting X.jar in a repository that has higher priority than
Y.jar.  Within the same repository, you can't control loading order.
For what repositories are available to you and their priority from the
webapp's perspective, RTFM on the Classloader How-To.

Then I'll just have to be more convincing.  Note that in the following scenario,
I deployed and then undeployed in two distinct operations.  The first deploy was
successful.  I then ran my application, terminated the session by invoking tag
 in taglibs-session.jar, invoked an undeploy, which
Ant/Tomcat reports as successful, and then attempted a deploy, which Ant/Tomcat
reports as failed.  I found that Tomcat removed context file billing.xml and
billing.war, but left behind taglibs-session.jar and the billing work folder. 
See details and additional commentary below.  Contents of context file
billing.xml and  tag are at the very end.

Compare the classloader docs for the two versions and see.  It's been a
while since I've used Tomcat 4, but my guess is that if you stick with
the standard locations (WEB-INF/lib, common/lib, etc.) then you should
be fine.

I'm not sure what this means.  Are you trying to control which jar is
loaded first in the classpath?

What are you trying to do?

Hi!

Just to add some info:

I've found some problem with Debian Woody + Sun 1.4.2 JDK... at least 
Tomcat 5 started up from jsvc fail at File.mkdirs (more info on 
http://www.mail-archive.com/[EMAIL PROTECTED]/msg131293.html

These problems doesn't exist on Debian versions others than Woody (to 
solve that, you should compile jsvc with "-lpthread", so, I think it is 
   a Debian Woody libc + Sun JVM only issue)...

What I said is not to comment out the Realm or modify it at all.  The
Realm and encryption are not one and the same.  You must have a Realm to
authenticate for the manager and admin webapps.

>a) does Apache need to be restarted (aswell as tomcat) when any changes

Generally no.  But also generally, at the beginning you should turn off
Apache and just work with Tomcat standalone, especially for basic issues
like this.

>b) which file can I look in to check $CATALINA_HOME?

It's a variable setting, it's not in a file.  Check your environment
variables to see if it's set specifically.  If it's not set, Tomcat will
deduce it as the parent directory above the bin directory.

Hi Andoni & Yoav.

I've commented out the Realm code in server.xml, so effectively there no

Tried Yoav's suggestion of defining rolenames for admin and manager - no
joy.

I agree with you Yoav - it is a trivial thing, but it's not working.

A couple of questions:

a) does Apache need to be restarted (aswell as tomcat) when any changes are

b) which file can I look in to check $CATALINA_HOME?

I have been using mod_jk2 for a long time now.  I have no idea why so
many people dislike it (well, after they get it compiled that is).  I
might just be blessed in that I run on win2k servers and can just get
the binary for mod_jk2.  I have never had to deal with the pain of
compiling this thing.   It is working great for me on a rather busy
little cluster of servers.

RE: Help with mod_jk2

 Just a simple questions, then an answer.

If you are front-ending Tomcat with a web server, why are you passing
things like .html, .gif, .jpg, etc. to Tomcat to process?  The web
server itself is a bit more efficient in handling this content.

Secondly, what web server front end are you using?

On Apache2/Tomcat4.1/mod_jk2, workers2.properties only defines my
workers, I set URI matching in my Apache Virtual Hosts Config;

Add something similar to the following for each vhost (copy & pasts is a
wonderful thing).


...
 
JkUriSet worker ajp13:localhost:8201
  
 
JkUriSet worker ajp13:localhost:8201
  
 
JkUriSet worker ajp13:localhost:8201
