De tomcat para websphere 7 = erro

Front-end
#1

Galera estou com o seguinte problema, estou mudando uma aplicação que roda no tomcat para o websphere application server 7 e ao publicar a mesma, o seguinte erro acontece:

Publishing failed
  The publish encountered some problems and the application may not have been installed or it may have been successfully installed but was unable to start.

Detalhe, a IDE tbm foi alterada para o RAD 7.5

Alguem tem alguma ideia do que pode ser ?

Cara, olha isso:

Mismatched serialization UIDs

Verifique se a aplicação está sendo compilada com uma versão diferente da JDK em que o Application Server é inicializado.
Também cheque se há dependências empacotadas na aplicação que já existam no servidor.
