pathanfiroz, what does your post have to do with GTWebDev's issue? You should have started a new post. But here is a hint. Note that the error message referenced a schema named HMRPTST. There is no such schema name used by jbossas, so it must be related to your application and *-ds.xml file. Most likely, the *-ds.xml file is attmepting to connect to the HMRPTST shcema in the database, but the database does not have such a schema. If this does not clear up the issue, post the *-ds.xml file (and use the Code button to format xml text properly, and use the Preview button to make sure the formatting is correct before posting) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4151132#...
