Subject RE: Connection Pooling (How i use...)
Date Tue, 06 Apr 2004 17:17:09 GMT
While using conn.close() does it return the connection to the pool??
Its not a driver connection rather a data source connection...so waht happens when i do conn.close()?
does it go back to the pool?

	This your problem: closing the connection in your try block. Move it to a finally block..
