JDBC connection check

[chicago1985]

I am always checking if any of my JDBC has Database leaks with our Oracle 9i database.

Here is what I use in SQL Plus:

select username, program from v$session where username = 'myUserSchemaName';

If I dont close my connections the above query shows a program running called JDBC Thin Client. If I do alot of JDBC inserts and updates in my Web Application, the query will show many lines of JDBC Thin Client showing up.
When I do close my connections correctly and do alot of inserts and updates in my Web Application, the above query doesnt show any programs running so I assume I dont have any database leaks?

This is my way and would like to know how experienced Java developers check to make sure all their Database connections are closed?

Use a connection pool and close the open connection in the pool at the end.
The Apache commons project has a few nice connection pools implemented.

kind regards,
