I want to code a program such that...my CMP Bean (using only one bean) should do
transactions on two or more tables. The transactions can be INSERT, SELECT....etc, that
why two prim key class tags are existing in the ejb-jar.xml. Which is the possible way to
code as such.
A Bean has to do transactions on multiple tables. Which is the best way to code in CMP?
I would be thankful if I get a suggestion.
Thank you,
Mallikarjun.
