WSIF EJB Binding Error

Question

Hi,
I create a very simple WSIF EJB binding, when running the BPEL process from the BPEL Console, I always got the "org.collaxa.thirdparty.apache.wsif.WSIFException: Class 'java.lang.String' is not compatible" error.
========================================
Here is the WSDL for the EJB:
========================================
<definitions name="DisconnectWebService"
targetNamespace="http://ord.itech.oracle.com/"
xmlns="http://schemas.xmlsoap.org/wsdl/"
xmlns:tns="http://ord.itech.oracle.com/"

</operation>
</binding>
<service name="DisconnectWebService">

jndiName="TestSessionEJB"
initialContextFactory="com.evermind.server.rmi.RMIInitialContextFactory"
jndiProviderURL="ormi://localhost/app"/>
</port>
</service>
</definitions>
========================================
Here is the error:
========================================
