Problem CreatingJMS-Implemented Weblogic Web Service

[Subhajit Majumdar]

Hi,

I am trying to create a JMS-Implemented web service (using WebLogic Server Version 8.1 sp4) for receiving messages from a JMS Queue. But each time I try to read the message from Service Test Page it throws a ClassCastException. I have used both java.lang.String and java.lang.Object as JMSMessageType attribute in servicegen ANT Task with same result.

Here is the ANT Task I am using:
<servicegen
destEar="${application_dir}/jms_recv_queue"
contextURI="WebServices" >
<service
JMSDestination="test.TestJMSQueue"
JMSAction="receive"
JMSDestinationType="queue"
JMSConnectionFactory="jndi.TestJMSConnectionFactory"
targetNamespace="http://tempuri.org"
serviceName="jmsQueueReceiveService"
serviceURI="/jmsQueueReceive"
JMSMessageType="java.lang.String"
expandMethods="True">
</service>
</servicegen>

Here is the stack trace:
