Yes, that would be one solution, but not suitable for our case because our
webmasters are constantly updating jsp pages on our production servers.
Btw. I'm using tomcat 5.0.28.
Thx,

Subject: AW: jspServlet runs out of memory while compiling some jsp files
using fork=true
Hi,
I would suggest that you do a precompilation of your jsps on a deployment
machine which is separate from the live machine.
So your compilation is not done on the live server, which might be on heavy
load.
Also you don't have the problem that the first visitor has to wait an awful
long time until the page get's displayed.
Cheers
Bernhard

Betreff: jspServlet runs out of memory while compiling some jsp files
using fork=true
Hi,
I'm having OutOfMemory error while Tomcat tries to compile
jsp files. The problem occures few times in day so it's quite
hard to repeat.
Tomcat is configured to run javac in separate JVM with
fork=true option. I tried to give more memory for ant using
ANT_OPTS, but it didn't help.
I read source code for the jasper compiler and there are
variables that configure how much memory is given to ant, but
I'm not able to configure them
with jspServlet init parameters.
How should I resolved this? Is the Jikes compiler a solution
worth of trying?
Stacktrace included below. I have hundreds of jars in
classpath... so I can't paste the whole compiler output.
BR,
Vesa Varimo
