In GemStone/J we do exactly what you are suggesting using
com.gemstone.security.ThreadOwner. This class maintains the association
between all Threads and the Principal that owns them.
Unfortunately the spec is open to interpretation in this area, so your
implementation depends on the EJB server you are using. You could add a
layer of indirection to protect yourself from this ...
Another way would be to have your Java classes use a statless session bean
to provide this service.

> What we need is each class in the calling hierarchy should know who is the

>
> This is simple when a bean talking to another bean, by using EJB's
> Entity/Session context information we can get the caller identity.
> e.g. A talking to B I am able to know the caller identity.

> But in my plain Java classes I need to know the caller. How can I do this?

> Where beans may be running on different threads, (Depends on container
> implementation), but anyway context information is there to save us.
