    Unable to Deploy a WAR file

    vijaiah vangara Newbie

      Hello All,

      My JBoss is all of a sudden giving this error at startup when ever i try to deploy a WAR file.
      It is working fine with EAR files. Recently i have changed my JMS default database from Hypersonic to Informix Database. Otherthan that i haven't made any changes.

      This is what the error i am getting. I have checked both Forums and the WIKI's. Please help me.
