Question

I’m creating a RESTful Webservice with JAVA and netbeans. The Webservice outputs correct JSON data BUT the problem comes in when I want to read a variable I sent via GET when calling the webservice from the browser.

When I try to output the variable that I just sent with GET, the WS gives back a NULL.
In addition , Glassfish server console outputs this :

• INFO: Couldn’t find JAX-B element for class java.lang.String
• INFO: Couldn’t find JAX-B element for class java.lang.String
• ….
• INFO: Couldn’t find JAX-B element for class java.lang.String
• INFO: Couldn’t find JAX-B element for class javax.ws.rs.core.Response
• INFO: Couldn’t find JAX-B element for class java.lang.String

Any help?

When using a @PathParam annotation you need to add the @Path annotation to the method declaration.

@GET
@Path("/{test}")
@Produces("application/json")
public String getJson(@PathParam("test") String test) {
    return test;
}
