    Problem adding module

    Michael Tanz Newbie

      Hi,

       

      although my application is for switchyard when it comes to modules I suppose this is the right place to ask.

      I need to access an external library from my app and therefore am trying to add a module for this jar.

      To be precise, I want to convert a XML string into JSON and therefore I need this lib "json-20090211.jar".

       

      This is the stack I'm getting

      I did follow the instructions on how to add a module but my problem is, I don't know if there are any and if so how to figure out what the dependencies for this module are. Is there a way without having to look at all the source files of the library?

       

      Thanks
