Get current SessionContext

[Martin Vysny <mv...@whitestein.com>]

Hi guys,
  perhaps a strange question: is there an OpenEJB-specific way to detect
if my code is currently being executed in a stateless session bean
context (and get its SessionContext)? In pure J2EE this is not possible
(unless you remember the SessionContext and store it into let's say
ThreadLocal), however, I cannot do that.
Thanks!
Martin

Um, just because you are using reflection instead of a direct thread  
local, doesn't make it legal.  I'd just use a thread local directly,  
because there are so may libraries out there that use them it is  
likely the code will work in any container.  Just be sure to clear the  
thread local in a finally block.

Okay, seems that the following snippet worked:

final Method m = Class.forName("org.apache.openejb.core.ThreadContext",
true,
Thread.currentThread().getContextClassLoader()).getMethod("getThreadContext", (Class<?>[]) null);
final Object result = m.invoke(null, (Object[]) null);
final boolean isInBean = result != null;
