I have a couple web services.
They both use some common xml schema, java classes, and binding files
that are maintained in a separate eclipse project.
Individually, each service, when built, pulls in the java code and
includes the bindings in its main binding. The external java code is
then compiled and run through the jibx binder and is used within the
project. All is good. Both services are happy and can be invoked
by clients built at the same time in the same manner.
I chose this approach as "pre-binding" where I ran the jibx binder on
the external project code and then tried to use it within the service
did not seem to work. Perhaps I was doing that wrong.
So, now I have one service that wants to call the other. Now it falls
down. The error I get is
[java] org.apache.axis2.AxisFault: java.lang.NoSuchMethodError:
edu.iris.ws.base.GeoLocation.JiBX_binding_newinstance_1_0(Lorg/jibx/runtime/impl/UnmarshallingContext;)Ledu/iris/ws/base/GeoLocation;
[java] at
org.apache.axis2.util.Utils.getInboundFaultFromMessageContext(Utils.java:486)
...
I *think* what is happening is a classpath issue. There are two copies
of the GeoLocation available, one for the first service's "external"
interface, the other for the first service to call the second service.
That seems wrong to me, but the above method is indeed missing from the
first service's GeoLocation class, while it exists in the second
service's GeoLocation class.
Is this a mess or what?
It appears that the first service's invocation of the second service is
successful (from tcpmon) and that the unmarshalling is failing.
How should I handle this?
Should I revisit trying to "pre-bind" the common classes? Is that
correct and I just didn't do it right?
Am I crazy for trying to do this?
thanks,
Linus
