Please check that in your <APPIAN_HOME>/ear folder you only have one file with a .dodeploy extension and not have any with .failed. For future references, you can upload the stacktrace in a document rather than copying it on different posts here, this will make the tracking easier.

Thanks Ricardo.I have deleted .failed file and jboss server started sucessfully.
