OK, I downloaded the zip file; how do I install it. It contains
StandardContext.class but i don't see that class file anywhere on my server.

Hi!
Find the default web.xml in $CATALINA_HOME/conf and change the appropriate
parameter for the jsp servlet to true. At least in Tomcat5 this file comes
with very good documentation.

Concidering that this poor excuse for an OS does not even know the
meaning of fork(), I'd say you set it to true. W2K should then start a
completely new process from scratch. You'll loose some performance of
course, since starting the JVM takes time and ressources, but if you
don't compile many, many jsps at a time, that should not be too much
of a problem.

I didn't catch the OP's OS, but this could be a catch-22.
I once ran into this one: Solaris fork() does copy-on-write for
efficiency but to be on the safe side it also reserves enough swap
to completely duplicate the parent process's mem, just in case.
You get the picture: if the parent JVM process is huge (more than half
the machine's overall mem) and it attempts to fork for a JSP compile,
you'll get a different out-of-memory error.
I don't know how Linux or other kernels handle this, but it's worth a
look before deciding between fork/not fork for JSP compiles.

Which bug are you talking about, the classloader reload memory leak or
the javac memory leak? The latter, they probably just fork javac by
default. The former, well, I'd like to see whether or not they do
suffer from that issue or not!

It could be. Someone here mentioned using Jikes for Tomcat as a workaround
(solution). I know that Jikes has bugs, here and there, but it can be made to
work and it comes with Tomcat. Considering that "javac" has an all present bug
(this memory leak), Jikes is better. I guess commercial solutions use their own
implementations or fork off to get rid of memory leak.
Why does JavaC have that memory leak?
Nix.

: always thought it was free of memory leaks.
This is a touchy topic, because a lot of it comes down to semantics:
Java frees the developer of explicitly destroying objects. This is key
in Java because your code only handles references, not true objects, so
you can't rely on something "going out of scope" to cause it to be
destroyed.
A simplified picture: Java's GC pretty much relies on an object having
no live references (connections) to it to determine whether to reap it.
So it's entirely possible to create a memory leak in Java if your code
manages to maintain reference to an object that's no longer "needed" or
"being used," because said object will never be reaped.

Thanks,
So far everything is going smoothly. I plan on manually restarting the
server once a day to clean up any memory leak problems. The semester is
over next weekend, so I just need to make it until then. I won't be
teaching the course again until next Fall, hopefully, by then the Tomcat
folk will have the memory leak problem fixed, or I can talk my
department chair into letting me renew my academic license with
macromedia for JRum. I'd rather stay Open Source but somtimes
commercially available software fits the bill better. Also, next Fall
I'm going to introduce EJBs and JBoss into the course, any suggestions
on using that combo?

Re: Need some Tomcat Configuration help badly
Posted by Antony Paul <an...@hotmail.com>.
Is your problem solved. I have noted one thing about Tomcat. If the compiled
classes modification date is less than that of the machine running Tomcat,
Tomcat will never know that the file is changed and never reload it. Only a
reload can load the new class. This is true for servlets,beans nad JSP. I
faced this problem when workstation machine time is behind server time. You
can overcome this by syncing all machines clocks. Or advise students to
perform a reload through the manager task. Or write an Ant script to reload
it.

Because jikes isn't as stable as javac, and not everyone wants to
install jikes on their server.
It's easy enough to get it going yourself, and it certainly compiles
JSPs a LOT faster than javac does.

I had the same question. In all of the years I've worked with Java I've
always thought it was free of memory leaks. If you use a different
compiler does the problem go away. Is that how people like JRun
(Macromedia) and WebSphere (IBM) avoid the problem?

It strikes me odd, I've been hearing about "memory leak while recompiling
JSPs" for a couple of years. Is it really there and is it going to be
removed in the near future? I recall that being attributed to "javac" memory
leaks. That's why they advise to pre-compile JSP for production environment.
I cannot fathom how can it be:
a) so consistent
b) not dependant on JDK version
Any insight?

BTW, there is a bug with Tomcat which will cause it to run out of memory
after a number of restarts. You will probably run into this with 30
students uploading new classes. You will also want to make sure that
the fork attribute for the JspServlet is set to true as well as
compiling JSPs will leak memory unless the compiling process is forked.
To work around the memory leak issue when the context reloads you'll
either have to regularly restart Tomcat, and you can also set the -Xmx
startup parameter to something like -Xmx256M or higher if your machine
has the memory so that it will take longer to run out of memory. By
default java runs as if -Xmx64M was set.
