JBoss can't compile jmx-console after deploying Cocoon

[pingles]

I've played around a little more and have the problem somewhat consistently appearing.

If I install the JBoss binary installation and then start the server using run.sh I can successfully browse to http://machine:8080/jmx-console/ or web-console to view the applications.

However, if I then deploy the Cocoon war file the server then falls over when I open the same applications. However, if I open up Cocoon it works fine.

Looking at the Java stack trace on the server, it seems to originate from JasperException, saying Error occurred at line: -1 in the jsp file: null.

Scrolling up through the log there is a java.io.IOException: cannot allocate memory. This occurs within the log for various JSPs.

It oughtn't be running out of memory, I've upped it to set the maximum heap size to over 128meg.

I was wondering if anyone could suggest why it would seem to work with Cocoon, but as soon as I copy over the Cocoon war it falls over.

Thanks again,
Paul

128 megs of heap isn't huge, you could still be running out of memory if Cocoon is loading large XML/XSL parsers into JVM (not sure what it uses).

There are several other reasons why you might get OutOfMemory errors, some are bugs, some are configuration issues, see the FAQ for some common causes.

Note that you probably have to do some fiddling with Xerces as well. Cocoon is very sensitive to using the latest version of Xerces. The stuff which is included in JBoss seems to be at least differently organized.
