Subject Re: [firebird-support] Aliases and FBWrappingDataSource

Hi Steffen ,

If you are using Tomcat you can use DBCP to pool your data sources and solve
this problem. The configuration of this is in the Tomcat docs.

I have a web app I run under Tomcat using DBCP and I can start and stop
Firebird with the web app running without restarting Tomcat or even the web
app. If Firebird is not running, it displays an error, when I restart
Tomcat and redo the search it responds normally.

The FAQ has all the Tomcat xml file examples for setting up DBCP connection

If you need help configuring DBCP let me know.
