How to get Session context in RESTFul services

[Raghunath Nandyala]

Hi

I'm developing java RESTFul services using netbeans . I want to access the HTTP Session attributes in my RESTFul services.

Im not able to access any servlet features in REST Services. Is there any bridge to access the servlet api from REST.

please help me ..

Are you using jax-ws and implementing Provider<Source>?
If yes then you should have a

@Resource
 WebServiceContext webServiceContext;

in your web service. webServiceContext will be initialized by the container. In your code do:

if ( webServiceContext == null ) {
 throw new RuntimeException("WebServiceContext not injected.");
 }
 MessageContext mc = webServiceContext.getMessageContext();
  ServletContext sc = (ServletContext) mc.get(MessageContext.SERVLET_CONTEXT);
 if ( sc == null ) { 
   throw new RuntimeException("ServletContext is null.");
 }

Hi!
If you are using a JAX-RS compliant web service stack, then you can annotate a parameter of the type HttpServletRequest with the @Context annotation.
Retrieving the HTTP session is trivial.
From the JAX-RS 1.1 Specification, section 6.1:

The @Context annotation can be used to indicate a dependency on a Servlet-defined resource. A Servlet- based implementation MUST support injection of the following Servlet-defined types: ServletConfig, ServletContext, HttpServletRequest and HttpServletResponse.

Best wishes!
