DataSource timeouts?

[VASQUEZ_JASON]

Is there any parameter that can be set to timeout datasources, or to 
re-init them after a specified period of time?  We recently bounced our 
Oracle database that our struts connection pool points to, and I noticed 
that all the connections had hung (the app just hung while trying to 
perform queries).  The only way to fix it (that I knew of) was to restart 
the servlet container.  Is there a better way around this?

Thnaks,
