Pinned topic Cognos 10.2 SDK: UnsupportedClassVersionError

‏2013-06-10T21:46:02Z |

I have an app which connects to the cognos environment using two jars axis.jar and axisCognosClient.jar

Cognos upgraded it's version from cognos 10.1.1 to cognos 10.2, I have extracted new jar files out of Cognos 10.2 SDK and inlcuded in my project, everything complied successfully but at run time I got the following exception..

Any idea why do we get his exception.

Any help is greatly appreciated.
