This happens on JBoss 3.0 with both Tomcat 4.0.3 and 4.0.4 as well as Jetty. This does not happen on Tomcat 4.0.4 standalone. There have been reports on the webwork user mailing list of this happening with JBoss 2.4.6 with Tomcat 4.0.3. Our test results were on Win 2k with IE 6. The WAR file attatched demonstrates the problem. ---------------------------------------------------------------------- >Comment By: marc fleury (mnf999) Date: 2002-06-28 14:09 Message: Logged In: YES user_id=174548 I will code a ZipEntry based UCL that lists what classes he uses, this will be blazingly fast. If the problem is the one you mention (large class space) then that will take care of it ---------------------------------------------------------------------- Comment By: Scott M Stark (starksm) Date: 2002-06-28 13:25 Message: Logged In: YES user_id=175228 An OptimizeIT profile shows the following hotspots: 76.36% - 406456 ms - webwork.view.taglib.ui.SelectTag.doEndTag() (SelectTag.java:89) + 54.41% - 289621 ms - webwork.util.ValueStack.findValue () (ValueStack.java:419) Ultimately there is a lot of time spent related to loading property editor classes so I'm guessing the primary difference between embedded JBoss vs a standalone web container is the very large shared class loader space. ---------------------------------------------------------------------- Comment By: Peter Kelley (yellekau) Date: 2002-06-25 18:42 Message: Logged In: YES user_id=561763 The test war file was too big to attach (~500K).
