Trying to run any ear file on Jboss2.4.4 I always get this log message:

[19:16:07,270,Default] PARSE error at line 3 column -1
[19:16:07,270,Default] org.xml.sax.SAXParseException: Element type "web-app" is not declared.
[19:16:07,270,EmbeddedCatalinaServiceSX] ContextConfig[/chat] Parse error in application web.xml
org.xml.sax.SAXParseException: Element type "web-app" is not declared.
at org.apache.crimson.parser.Parser2.error(Parser2.java:3086)

It is due to parser uncompatibity!
Jboss test runs on Jboss2.4.4
Thanks for any suggestion
