Hi,
I have to do a Web service that also consumes the DFS services so I can create new documents in Documentum 6.5.
I downloaded the DFS SDK sample codes and executed them. All worked correctly.
After that I tried to create a Java Web service that executed the same code as, for example, TQueryServiceTest java class.
I created a class like this:
It has the same code as the class TQueryServiceTest but erasing main method and changing it by a "SUMAR" method.
I'm using Tomcat 5.5 with Axis2-1.5.1 and JDK 1.6. and Eclipse Helios.
I'm creating the web service using the wizard. First a Dynamic project and after that creating the class and from the class creating a web service. After that, I add the jar files coming in the DFS SDK package.
When I run the web service and execute the "sumar" method. It only has to add two values, but also execute the TQueryService logic.
The error it gives me is
[ERROR] javax.xml.bind.MarshalException
- with linked exception:
[javax.xml.bind.JAXBException: com.emc.documentum.fs.services.core.Execute is not known to this context]
java.lang.reflect.InvocationTargetException
