Thank you, I am already using a different method name then the interface name, I read about that on Kathy's wickedlysmart web site. My method name is "getMessage()"

Hi,
Following is the second rule about the mapping requests to servlets on page 85 of Servlet Spec 2.4.
I am not able to understand the rule. If some one can explain in a bit simpler english please (with example will be great).
" 2. The container will recursively try to match the longest path-prefix. This is done
by stepping down the path tree a directory at a time, using the �/� character as
a path separator. The longest match determines the servlet selected."
THank you

Hi,
In CMP we dont map foriegn key in relation between 2 two beans. We use the CMR feild instead (the bean itself ).
Does that mean that in the Relational database table there is no foriegn key as referential integrity between two tables ? Please explain.
Can we built entity bean based on the existing tables, in that case what do we do with foreign key ?
THank you.
