i'm gettin a strange error while running my weblogic application
i have connection object returned by the connection pool which looks to be of weblogic.jdbc.rmi.SerialConnection class.
the problem occurs when i try to execute successive createStatement calls on the same weblogic.jdbc.rmi.SerialConnection object. it works fine for the first call but gives NullPointerException for all subsequent calls.
where can i get more information bout this NullPointerException class to know whether and how createStatement is overriden since no javadocs for this particular class seem to be in existence.
what are the possible causes of the occurrence of this NullPointerException??
