programmatically checking for open connection in JDBC

Question

How do I check for an open connection in jdbc for oracle database?

Note: conn.isClosed() cannot be used for this.

See this posting.

The referenced solutions are similar to the one posted here (quick query against DUAL to validate) but there is also an interesting solution provided by JBoss specific to Oracle using the proprietary PING method in the Oracle JDBC Connection class. See the code here.
