Re: java.lang.ClassNotFoundException: com.mysema.query.types.EntityPath

Hi.

What is your build system, Maven or Ant?

Do you use Querydsl with Spring Data JPA?

Br,
Timo

Hi.

I am not familiar with Struts 2, but it looks like a classpath issue.

Maybe try building a war and look into the WEB-INF/lib folder and verify that Querydsl and transitive dependencies are available.

Timo

Yeah that is the problem i don't have the queryDSL jars in the lib folder even though i selected the user library to be exported and published... I will try copying them in the WebContent/lib folder  and answer back.. But that is surly the problem

Thanks Timo..
