metatech commented on DBCP-221:
-------------------------------

If you wish to terminate active connections as well, you can try the following 
code.  
Note : the BasicDataSource must be created with the property "removeAbandoned" 
set to true.
{code}
ds.setRemoveAbandonedTimeout(1);
ds.setMaxActive(1);
Connection conn = ds.getConnection();
ds.close();
conn.close();
{code}
However, with the Oracle JDBC driver, the code can fail when the active 
connection waits for a database lock, because of a Java lock in the JDBC 
driver.

> Suppose there are several connections being used now by different servlets. 
> calling the basicDataSource,close() does not have any impact on the 
> connection pool. I expect that after these servlet return the connections the 
> pool should be shut down immediately. I also expect that any more requests to 
> borrow connections from the pool should not be fulfilled. However, my 
> experiment does not seem to support my expectations. Calling 
> basicDataSource.close() seems to be ignored while there are connections being 
> used.
