Subject RE: Axis2 1.1.1 session works fine in browser but doesn't work in Stub client.
Date Mon, 29 Jan 2007 15:27:27 GMT

Hi,


Actually The web service works perfectly when I use browser to invoke
the web service from
http://localhost:8080/axis2/rest/MySessionService/plusone. It returns
exactly 1,2,3, ..., n when I refresh n times.

The client Stub returns only 1,1,1... (should be 1,2,3...), even if I
call multiple times in the same stub. I used tcpip monitor to track the
raw traffic, the stub call doesn't contain JSESSIONID cookie at all.
That is also explained why browser invocation remembered session but
stub invocation didn't. Although I followed the step to enable session
in client stub 

stub._getServiceClient().getOptions().setManageSession(true);

somewhere in stub settings is not right because it doesn't return
JSESSIONID to server at all. The 1,1,1 returns are caused by server
treating each call as a new session.

Bug#
https://issues.apache.org/jira/browse/AXIS2-2042


To: Sanjiva, I need SessionContext instead of ServiceContext, 

	private SessionContext getSessionContext() {
		MessageContext messageContext = MessageContext
				.getCurrentMessageContext();
		
		SessionContext sessionContext = null;
		if(messageContext != null) {
			sessionContext =
messageContext.getSessionContext();
		}

		return sessionContext;
	}	

To: Deepal, I've also enabled transportsession in service.xml

......
<service name="MySessionService"  scope="transportsession">
......

Thanks,
Sam.

Hi ;

SessionContext is the one which keep transport dependent session data ,
and that will be only created if the service is deployed in transport
session.

Thanks
