How to identify the current running context?

[Boopathi Ramasamy]

Hi, I have a class file that needs to identify the context it is currently running in. Based on its context my logic will differ.
For ex: my class can be instantiated by a servlet or a session bean. How do i find out at runtime, the code is getting called from servlet or ejb?

Boopathi,
Can you pass this information to your class when you instantiate it?

Hey,

There is a class called: SessionContext, that you can inject with EJB 3.0, or, I guess, lookup in EJB 2.x.

SessionContext extends the javax.ejb.EJBContext class. EJBContext defines several methods that provide useful information to a bean at runtime.

There is a lot of information about this class in the Enterprise JavaBeans, 3.0 By Bill Burke, Richard Monson-Haefel, (O'Reilly).


Hope this helps,

It is usually an indication of poor design if you need to know in what context you class exists. It makes your class non portable...
