ja pensou em recompilar a classe !!!

resolvido galera…

aconteceu isso comigo e o problema era esse:

na declaracao de package assim dá esse erro (example.xml):

 <package name="example" namespace="/example" extends="struts-default">

e assim corrige o problema:

 <package name="example" namespace="/example" extends="default">
