Hi All, One of the existing application which is used over a period of time causing a problem all of sudden. When investigated i found the Statment object is not returned from the Connection object. System.out.println("Connection is closed " +conn.isClosed() ); //isClosed() is returing false, which making me to belive connection is fine. Statement st =conn.createStatement(); //st is null
What whould be possible reason createStatement method return null... Thanks in advence for help....
System.out.println("Connection is closed " +conn.isClosed() ); //isClosed() is returing false, which making me to belive connection is fine
Instead of this one check out if (conn == null) if yes then conenction might not have established.
As per my knowledge u might not get the statement object because the connection object is not obtained,you can try out the check for connection object like above mentioned ie for null.

Hi Jignesh, Actually if connection was null, then when i tried createStatement() on connection object i should have got null pointer exception. However i tried your condition and i found that connection is not null. Any other inputs.... Thanks

Hi Guys, Thanks for your response. The problem is resolved, The cause for the problem was the classpath. I mean the driver present in the classpath was not one expected. Hence on correcting the classpath, application is working fine. Regards Arun
