Subject RE: OutOfMemory exception explanation?
Date Tue, 27 Jan 2004 17:57:22 GMT
Thanks for the suggestions, I do have a question though.  

As I indicated, the problem, when it occurs, only effects 1 of the many
servlets.  We have 2 WebApps running, both with a few servlets.  This
occurrs only on 1 servlet, and once it has errored, it causes that
servlet to function improperly.  Only that servlet, and even after
completely removing the webapp that housed the servlet and re-adding it.
Does this still sound like a problem with my webapp?  Why doesn't Tomcat
re-initialize the container which housed the servlet?  Thanks again, I
will look at profiling my app to see where there may be a failure.

Apache JMeter

And if you use eclipse, there is a plugin project on SourceForge called
EclipseColorer.

Hope there were more tutorials on how to use them though.

I've looked for a free profiler, but was unable to find one (as in beer
or speech).  If you can deal with the barrage of sales calls, you can
download a trial version of:

JProbe: http://quest.com/jprobe/try.asp
OptimizeIt:
http://borland.com/products/downloads/download_optimizeit.html

And...well, I forgot the third one I knew about.
