Question

This is the way for me to get my connection

DataSource ds = (DataSource) ctx.lookup("glassfish_pool_res");
connection = ds.getConnection();

After I use the connection, like this:

CallableStatement cs = connection.prepareCall(call_statement);
...
cs.execute();

should I do cs.close() and connection.close() right after?
Is that the right way to close the connection to avoid memory leaks?
I’m developing a web application btw.

Answer 1

Yes. That is right way to do.

close()  returns connection to connection pool
