Summary: Call to JMX leads to failure in EJB call.
Initial Comment:
Hi,
When I do a standard JMX call from an servlet the next
call to an EJB fails.
This happens on jboss-3.2.2 on on sun jdk 1.3.1_08-b03.
As an exapmle I have added the following code to the
jaas_howto code (the one that is updated for 3.2.x ):
In the file "EJBServlet":
protected void processRequest(HttpServletRequest
request, HttpServletResponse response)
throws ServletException, IOException
{
try {
System.out.println("Trying
a to lookup the Adaptor...");
InitialContext ic = new
InitialContext();
RMIAdaptor adaptor =
(RMIAdaptor) ic.lookup("jmx/rmi/RMIAdaptor");
System.out.println("Using
class: [" + adaptor +"] as the RMIAdaptor
implementation.");
ObjectName name = new
ObjectName("jboss.web:service=WebServer");
System.out.println
("ObjectName: " + name);
Object attr = adaptor.getAttribute
(name, "Name");
System.out.println
("QWERTY: " + attr);
} catch (Exception e) {
System.out.println
("Exception: " + e.getMessage());
}
String method = request.getParameter("method");
if (method == null || method.equals("echo"))
callEcho(request, response);
else if (method.equals("noop"))
callNoop(request, response);
else if (method.equals("restricted"))
callRestricted(request, response);
}
This code executes ok, but the following call to an EBJ
fails with an:
javax.security.auth.login.FailedLoginException.
Please see the attached file for a full stacktrace.
The code works correctly if I remove the the call:
adaptor.getAttribute()
Can anyone please help with this?
Is this a bug, or am I doing something fundamentally
wrong?
Thanks!

The RMIAdaptor is only designed for use by clients external
to the server VM. It clears the thread security association
so that the call security context does not leak back to the
calling thread pool and this results in the secured EJB call
failing.
You need to use the MBeanServer directly.
MBeanServer server = (MBeanServer)
MBeanServerFactory.findMBeanServer(null).iterator().next();
