Applies to:

Information in this document applies to any platform.

Symptoms

When compiling/building WTC application 12.2.1.1 or before, that application does not work on 12.2.1.2

When calling Tuxedo service, following exception occurs.

java.lang.IncompatibleClassChangeError: Found interface
weblogic.wtc.gwt.TuxedoConnection, but class was expected

examples.jolt.servlet.simpapp.SimpAppServlet.doPost(SimpAppServlet.java:106)

weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:286)
at
weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:260)

If the application compiles on 12.2.1.2, it works well.
