Hai,

your links are well, but I am getting one doubt ,

How we can test this transaction attribute for a method

is working well.

and there is also another doubt to me that is as follows:

There are two methods are there in a session bean named

a(), b()

I am calling method b() in a(),

If a client calls a()(inserting data in database using a entity bean's create method) worked perfectly, but while calling b()(retrieving data using entitybean's finder method), there is an error , in this situation I need to

roll back a()'s work How i can do that

How can we use CMP Transaction attributes on this two methods (a(),b())in this Scenario,

Please help me in this regard

Thanks & Regards
