how can I capture a network failure in datasource.getConnection()

how can I capture a network failure in datasource.getConnection()

Hi all,

We are using a connection pool in Tomcat using commons dbcp classes
DriverAdaperCPDS (with com.sybase.jdbc2.jdbc.SybDriver class from sybase)
and PerUserPoolDataSource. The set-up using server.xml JNDI binding etc. are
working fine and the site works well most of the time. The application is a
publicly hosted web site expecting a lot of concurrent visitors.

We experienced that at times our pages hang and we found that the problem
could be because there is some network problem between tomcat 4.x and sybase
12.5. To simulate our case, we removed network cable and found that the code
hangs at this line:
Connection con = datasource.getConnection(),
though the SQLException over this statement is caught.

Anybody has any idea as to how to trap such na network failure and do a
exception handling inside the code itself.

Thanks in advance.

Regards,
Partha
