ConversationScoped - cid from http header instead of query parameters

[poiu77]

Hi.

I want to use conversation scope in application where JS client call rest services. Each of service must be called with proper cid value. For transfer cid I want to use http header instead of query parameters. Is it possible to do without create my own scope? I've found class ConversationContextActivator where cid is determined from request parameters, but I'm not able to change it by configuration, injection, etc.

Anybody had similar problem?

Best Regards, Darek.

Hi Darek, this is not possible right now. The spec defines that cid must be either in query string or in posted form data. Maybe you could use a Servlet filter, wrap the request and extract the conversation id from an HTTP header?

Hi Martin.

Thanks for response.

I've tried to use HttpServletRequestWrapper in @WebFilter but without success. I suppose my implementation was not visible during determining "cid" in ConversationContextActivator. There was HttpServletRequest object visible instead of my wrapper.

I think I have to use default way for transport "cid" in http parameter.

Best Regards, Darek.

Oh yes, I've forgotten to mention that you'll have to map your filter before the "CDI Conversation Filter". See also the CDI Conversation filter section in the docs.

Hi Martin.

Now it's working as expected. Thanks a lot.
