All of these jars are not necessary in JBoss, because JBoss has its own version of some of them that it prefers to use. Unfortunately, some of them actually cause JBoss to not deploy your war, but because the war is packaged as generically as possible we don't just exclude these jars. So the solution is for you to open up the war, delete the necessary jars, repackage the war file and redeploy it. The list of jars that COULD cause trouble are: activation.jar concurrent.jar dom4j-1.5.2.jar hsqldb.jar jaxen.jar mail.jar saaj.jar jaxrpc.jar xercesImpl.jar xml-apis.jar cglib-2.1.jar commons-httpclient-2.0.2.jar commons-logging.jar log4j-1.2.8.jar jsp-api.jar servlet-api.jar asm.jar asm-attrs.jar ehcache-1.1.jar hibernate3.jar jta.jar foEmitter.jar htmlEmitter.jar portlet-api-1.0.jar The jars that are most likely the root of your problem are servlet-api.jar and jsp-api.jar. I would recommend removing atleast those two, redeploying and seeing if you experience any other troubles. Let me know how it goes for you!
