AS7 Class Cast Exceptions from common jar

bill.rosenberg Oct 27, 2012 6:41 PM

My app is structured pretty simply:

App.Ear

-AppEJB.jar

-AppWeb.war

-/lib

-AppCommon.jar

Both the ejb and web share the AppCommon classes by default since it is int he /lib directory under the EAR. I do not reference the AppCommon.jar in any manifest or in jboss-deployment-structure.xml files. In the application i am seeing exceptions like the following, where they seem to be the same class type, but jboss is throwing a ClassCastException. The 'com.lightspeed.dao.availability.Rate' class is inside the AppCommon.jar which

is shared.

16:22:46,331 ERROR [stderr] (http-localhost/127.0.0.1:8443-1) java.lang.ClassCastException: com.lightspeed.dao.availability.Rate cannot be cast to com.lightspeed.dao.availability.Rate

Any ideas?

Thanks,

Bill

Are you sure that a copy of AppCommon.jar has not made it's way into the WEB-INF/lib directory of AppWeb.war?

Stephen,

That is exactly what happened. Myclipse has an option of 'smart' deployment for web apps that was merging all the common classes into the classes directory of the web app. Once I set to manage myself, these went away. Thanks for the response.
