Subject RE: [S2] Using complex objects in JSP
Date Fri, 11 May 2007 11:15:42 GMT
Hi Don,

Thanks a lot! I'm reading all about OGNL to work with POJOs, and it's
interesting.

Thank you again for helping me :)

Cheers!

All you need to do is expose your TResultSet object via a getter on your
Action, then access it like any other object using JSP-EL in your jsp.
You can even use the JSTL for-each tag to handle iteration.  For
example, if you exposed this object using getResultSet(), in your jsp
you could access it via ${resultSet}
