Re: EAR can't find WEB-INF/classes or WEB-INF/lib
Finally found out what I needed to change: I just needed to use Thread.currentThread().getContextClassLoader()... I don't know if that's going to be perfect, but it seems to have solved my problems for now. Bloody Classloading stuff. Thanks for your help. Now I can have the joy of converting a WAR to an EAR. Is there any particular reason I can't have an exploded WAR inside an unexploded EAR file?

If we do permit graphics/symbols they can be attached to the JIRA with permission granted to Apache via the checkbox as a way of formally documenting the approval to include the image. I still like the JIRA idea but on further reflection I suppose the check box can't be used for this purpose. I like the Jira idea, also.

So, without a bit of reading on my part, I'm not entirely sure of the effect of your tuning parameters. Does your application actually require a 5 gig heap? What's your CPU utilization look like during periods of slow response time? IIUC correctly, the below results are for retrieval of a static text file. However, there is additional activity on the server (retrieval of Shockwave Flash files and a URL proxy). Is that correct?
