Hi,

We work on NAS(Netscape Application Server), version 4.0. Session  bean
is the middleware used to make JDBC calls to the database. It uses a  bean
managed transaction.

I tried to change its transaction attribute to Transactoin Required (for
making a
container - managed transaction). For that I  had to register the Resource
Manager. In the implementation class's various methods, I declared
the "java.sql.Connection pConn = null;". Then I opened the connection and
made
the JDBC call. But in some cases, it  threw an exception "Global Transaction
not
started". I can't figure out why  this is happening.

There's one more problem that I occasionally face - "A Transaction is
already associated
with the current thread". I absolutely haven't been able to understand
what's happening.
It would be really nice if anyone helps me out.

Thanks,
Tilak
