----------------------------
Thank you for your valuable comments .
We are planning a upgrade cxf version in coming months ,we will use as your
suggestion.
It would be great if you provide your insights so as to why the same issue is
not occurring when 2.4 version of cxf is used .
Thanks a lot once again!!

> 1. Testing using a standalone java program.
> 2. This doesn’t happen when apache cxf version 2.4 is used .
> 3. When upgraded the version to 2.6 and above ,we are facing this issue.
> Code used to invoke the webservice is :
> TestService service=new TestService();
> Client client = ClientProxy.getClient(service.get*);
> Map<String, Object> requestContext = client.getRequestContext();
> requestContext.put(org.apache.cxf.message.Message.MAINTAIN_SESSION,
> Boolean.TRUE);
> requestContext.put(ENDPOINT_ADDRESS_PROPERTY,faxUrl);
> Object[] logOnResp= client.invoke(“webservice”,param1,param2,param3,param4);
