I am getting the following error while running the sinmple struts application on jboss5.The same application is running perfectly fine with JBOSS4.0.5GA.The error is as follows:16:24:05,752 ERROR [[/Struts2HellowWorld]] Exception starting filter struts2Caught exception while loading file struts-default.xml - [unknown location]
Check to see what changed with regard to Struts from JBOSS 4 to 5. Believe the 2nd result - the fact that it's running "perfectly fine" on JBOSS 4 isn't applicable if you want to run on JBOSS 5. I don't know what is different, but something is. Check the JAR versions. I'd also check the struts-default XSD or DTD and see if something is different there. Maybe the namespaces have changed.
