I didn't look at your code, because its not properly quoted using CODE tag.
And telling "it doesn't run properly" convey nothing, have a look at this for what I want to say.

the code compiles fine but throws a runtime exception.
it connects to the database properly...
the only problem I see here is when its extracts the data from ResultSetMetaData.
i ve marked that code "red" where its showing error...
so if anybody has any idea........please help
