i am using entity bean(CMP). The spec mandates that entity bean component interface should use getPrimaryKey() wich takes single argument.If i am having a customer table that has 4 columns. CUS_ID,CUS_ROLE,CUS_FNAME,CUS_LNAME.
In this CUS_ID,CUS_ROLE both has combined as a primary key, in that case how the getPrimarykey will works

Vijay,
You would have a primary key class containing all the fields of the primary key. Then it works just as if your key was a String.
