I am new to web services. I got NoClassDefFound Error while deploying the web service in . I am trying to access some classes defined in the jar file which i have included in the axis2 archive (.aar) file. But when i tried to deploy the service I got the following Error message in the Tomcat Console

So where is class "com.krish.MyException"? Axis obviously can't find it.
It is in the jar file MyJar.jar which defines the MyException class. And I have included the MyJar in the .aar file. but still it says NoClassDefFound Error
Thanks Krishnan Sreeraman

Are you certain that .aar files can contain .jar files (as opposed to a hierarchy of .class files)? I would be surprised if that's possible.

I am not sure if I am right can you suggest me some ways to access the MyException class in MyJar.jar file.
Thanks in advance

As I said, I don't think that's possible. Try packaging the aar file with a loose hierarchy of class files instead.
