to use?

By the way Andrius where are you right now (Lithiania)?

i had lots of out of memory problems, but this was entirely my
application, it was not either tomcat's memory management problems  
(yes, i
redeployed frequently). i think you should run a profiler.


I know, I can restart Tomcat, but this is not solution. I will come  
to
same
problem after few days or weeks againt. It can be treated as work
around.
I'm not sure that switching to velocity will fix the problem. I  
looked
for
information on google and found that problem can by caused by tomcat
deployer or manager. As someone noted there is a memory leak when  
tomcat
undeploys webapplication. So after few redeplayments I will come to  
the
same
problem.

I looking forward to switch to Tomcat 5.0, Jetty or Somthing else,  
not
sure
yet.

Any more solutions? Does anyone had same problems? What they did?

Regards Remis.

An error occurred at line: -1 in the jsp file:
null
Generated servlet error:
    [javac] Compiling 1 source file


The system is out of resources.
Consult the following stack trace for details.
java.lang.OutOfMemoryError
at




org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorH 
andle
r.java:130)
How to deal with that and where to look for
solutions. Can it be somehow
related with javac memory leak?
Restart your server :) It seems that  every
redeployment causes
recompilation of jps classes. And java classloaders
are great in loading classes, but not so good in
disposing unneeded ones...
I would recommend to dump your jsp and go velocity.
It's faster and esier to handle anyway....
