Returning com.adobe.idp.Document as complex return type

Hi,

I'm developing a custom component and need to return a Document type along with other parameters. Therefore, I bundled all return parameters as a complex return type and defined the binding-type="Bean" for each of the output parameters. Now the service fails to activate with the following error in jboss logs (it works with simple types like int, String, etc). Any idea what might be wrong?

Thanks,

yyz
