Hi,
I have a qusetion about freeing of resources when I am using JDBC code.My application works pretty well for sometime and after sometime it behaves in a weird manner.Basically my application involves servlets talking to backend database and retreiving the results back.To remedy for the solution I have to restart my application server and you know what it works pretty well this time.In my JDBC code I did not close my statement but I did close my connection and it works fine.Also I am using the CreateStatement() in a try block.Is it advisable to use it there or put it before the try statement,could anyone please let me know of what exactly is happening here.
Thanking you,
Ashwin

You need to close your result sets and statements or the database resources will eventually be used up. This is usually done in a finally block.
 
It is sorta covered in the JavaRanch Style Guide.
