paolo....i'am following your steps hahaha, i edit in hwlloworld.war the jboss-web.xml file for changing the path but jboss send and error that in the web.xml file doesn't found something,
If you use a jboss-web.xml like mine, you probably miss the resource-ref element in web.xml in your portal instance. This is the requested part of my web.xml
<resource-ref> <res-ref-name>jdbc/MyPortalDS</res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> <res-sharing-scope>Shareable</res-sharing-scope> </resource-ref>
the res-ref-name must be the same datasource name you have in the datasource descriptor file in the deploy folder of your jboss. (for example portal-mysql-ds.xml); other fields are unknown for me and I didn't touch them.
I hope this is usefull to you.
