I’ve been plowing through Maven2 & Weblogic at work recently, in an attempt to get an EJB/MDB & EAR deployed for testing out JMS. I would often hit the following errors when deploying an App in Weblogic 9.2:
- Unable to access the selected application.
- Exception in AppMerge flows’ progression
Baffled, I almost gave up – the errors mean nothing.
Thankfully trial and error (and plenty of web searching) I have discovered that the errors are caused by invalid deployment descriptors or invalid WAR/EARs (an empty WAR or EAR will cause these errors immediately). So don’t fret, it’s not the end of the world!
First check your web.xml, application.xml and then ensure the contents of the WAR/EAR are as expected – APP-INF, META-INF only for the latter!
Hope that helps someone, it annoyed me for a while!
