Web application consuming Web Service Connector

Hi experts, I’m new in this technology and I’m experiencing a problem creating a view showing a table in a web application.

The project is formed by an adapter invoking a the sentence select to a particular database, a Web Service Connector including that adapter and inside de Web application a view executing that connector. The problem is when I press the button refresh, I get the exception com.webmethods.caf.faces.data.ContentProviderException: java.lang.reflect.InvocationTargetException.

I tried to do this example many times and always I got the same error. What could it be?

Thanks in advance!

Maybe this could help you:

Otherwise, this could be an authentication problem. Consider using “Hybrid” authentication for the service call.
