Hi all,
I have a JSF managed bean invoking a Stateless bean with REST interface.
Everything works fine until I use a @Context UriInfo in the EJB. It looks
like this.
The managed bean injects a reference of the EJB and initializes the message
attribute in the @PostConstruct :
@ManagedBean
public class MyController {
@Inject
private MyEJB myEJB;
private String message;
@PostConstruct
private void initList() {
message = myEJB.displayMsg(42L);
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
The Stateless EJB has a @Path annotation and a @Get method that just returns
a String :
@Stateless
@Path("/msg")
public class MyEJB {
@Context
private UriInfo uriInfo;
@GET
@Path("{id}")
public String displayMsg(@PathParam("id") Long id) {
return "You've found id number " + id;
}
}
This simple code will not wok and I'll get a : Exception creating stateless
session bean : [MyEJB] with the following stack trace :
A system exception occurred during an invocation on EJB MyEJB method public
java.lang.String org.agoncal.example.MyEJB.displayMsg(java.lang.Long)

But if I take the @Context private UriInfo uriInfo out, it works. I've
reproduced this behavior on GF 3.1.1-b12 and GF 3.1.2-b03.
Do you know why @Context UriInfo makes this kind of error ?
Thanks,
Antonio
PS : I've sent this email to both users_at_glassfish.java.net and
users_at_glassfish.dev.java.net as I don't know if both are the same
