I have run with a similar environment and found no problems at all, so it's not a problem with JBuilder per se, perhaps they way you have it confgiured.
I would recomend you install the latest patch for JBuilder 6 (available at the website) and try it against an External instance of Tomcat 4 as suggested elsewhere. The other thing to try would be to upgrade to 4.0.2 and test against that. Sorry I cant help any more, but if you supply more info on your configuration perhaps I can. Im certain its a config issue and not a JBuilder/Tomcat issue.
