Vague error produced for ServiceClient invocation within a service where class
pathing is a problem
---------------------------------------------------------------------------------------------------
Key: AXIS2-2972
URL: https://issues.apache.org/jira/browse/AXIS2-2972
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Components: databinding, deployment
Affects Versions: 1.2
Environment: Running in windows XP under eclipse and with axis2 1.2
embedded under Jetty.
Reporter: Jason Kania
The problem I have seen occurs when a component is not in the deployment
directory, but is being referenced externally. Instead of encountering a
ClassNotFoundException or similar, a vague error is produced when attempting to:
1) create a ServiceClient within a service
2) load a configuration context within a service
The client was external to the jar because it will be used both remotely and as
a part of the service. The text of the exception is misleading because the
receivers in use as per the services.xml have nothing to do with those seen in
the error.
To create the error, simply attempt to create a new ServiceClient() in a class
that is not contained within the deployment directory, but is referenced by a
class in the deployment directory.
The error seen is the following:
java.lang.ClassCastException:
org.apache.axis2.receivers.RawXMLINOnlyMessageReceiver cannot be cast to
