Handler Class - Is it correct?

Hi all,
As part of the java application I am developing, I have written a handler class ( which uses reflection to populate java objects from data extracted from an Oracle database. My application only has approximately 40 concurrent users, but performance is currently atrocious and profiling has idenitified that the majority of memory is being used by the handler class.

Is there any chance that someone way more experienced and skilled than myself could take a look at the code below and suggest where I might be going wrong. Its driving me nuts!!!

This in turn is called from the following method located within my factory class (

Any advice or assistance that anyone is able to offer on this would be greatly appreciated.

You might want to mosey over to the Java APIs forum, where the authors of Java Reflection in Action are helping to answer questions this week:

"This week, we're delighted to have Ira R. Forman and Nate Forman amongst us, helping to answer questions in the Other Java APIs forum.

We'll be selecting four random posters in this forum to win a free copy of their book, Java Reflection in Action, provided by the publisher, Manning."

Your main problem is your largescale use of reflection.
While using it can help you do things that aren't otherwise possible (at least not easily) it does have a pretty hefty performance penalty.

I agree. Here's the link:
