Subject RE: Configuring DataSources using jsp: reload context.xml?
Date Mon, 07 Jul 2008 07:54:27 GMT
Good morning,

I'm still trying to figure out how I can cause tomcat to re-read JNDI
resources. Here is one way I found out earlier:

As you can see, this only works from within Eclipse, and I have no clue
how I could cause a JNDI reload in a production environment. In the
meantime, I tried some further things, e.g. updating the
last-modified-date of web.xml to cause a redeploy. I also did some more
googling, but to no avail.

Does anybody know a way to cause Tomcat to rebuild the JNDI context of
an application? Or is there a better way to dynamically configure Data
Sources? Any ideas are welcome.

In the worst case I'd need to fall back on a custom config file and
database connections using DriverManager, but this would destroy all
benefits of pooled connections etc :-(
