Subject Re: XSL Transformation in Xalan - Pls help!
Date Tue, 16 Sep 2008 16:08:11 GMT

I vaguely remember a situation in the past where JBOSS and Xalan-J were
running together in the same JVM, and running out of memory. What I
remember was that JBOSS was a memory pig, and that there wasn't much
Xalan-J could do about that.

I don't know much about JBoss, but it's a pretty huge application. You
may be testing JBoss instead of Xalan. In order to test Xalan, I'd
rather use a leaner frame, maybe just the simplest of programs which
does what you describe below using loops and timestamps.

Sounds very reasonable to me.
