Error while invoking web services from Proxy services in OSB

Question

I have a Proxy Service of message type in Oracel Service Bus 10gR3 and it passes the incoming messages from a JMS Queue to Business Service of Web Services type. This Web Service is hosted in Glass Fish v3 and it's binding style is RPC. The JRE used in both the servers are 1.6.0_20. The JMS message is of Text type. The Web Services at the Glass Fish throws MessageCreationException for any content of the JMS message. However, it works fine if Business Service's test client is invoked from the OSB'S Admin Console. However, the same will not work if Proxy Service's test client is called.
The detailed exception stack is given below :
Thanks for the help.

Answer 1

Let me explain what I am trying to achieve. Our application receives data from multiple sources - from mainframe using FTP, JMS Queue and BPM application using Web Services. The data from all these sources are sending to a Web Service running in GlassFish V3. To handle this I have created three Proxy Services and one Business Service on OSB. The Business Service is of type Web Service using the same WSDL from the target Web Service.
The Proxy Services are configured as follows:
Proxy 1 (type - Messaging service) listens to the JMS Queue and receives JMS Text Message -> Business Service(B1) (Web Service).
Proxy 2 (type - Messaging service Polls files from the FTP Server -> Business Service(B1) (Web Service).
Proxy 3 (type - Web service) is invoked by the BPM application and sends a String -> Business Service(B1) (Web Service).
All the Proxies route to the same Business Service - B1 which calls the Web Service in GlassFish. The only Proxy that works fine is Proxy 3 which is created using the same WSDL of the Web Service. In the other two proxies it thows the same exception in GlassFish as I mentioned before.
com.sun.xml.ws.protocol.soap.MessageCreationException: Couldn't create SOAP message due to exception: XML reader error: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog at [row,col {unknown-source}]: [1,0] at com.sun.xml.ws.encoding.SOAPBindingCodec.decode(SOAPBindingCodec.java:359)
Is this configuration correct to achieve my requirements?
Once again thanks for the help.
