The problem is now solved, though in a somewhat unsatisfying way. I
wrote my own configuration file to store information about the data
sources, and now I connect to databases using DriverManager.
I'm still wondering about more elegant ways to do dynamical
configuration of data sources. Would it
be a better and simpler
option.

Thanks Sameer for your reply!
That may work for new datasources but could create a problem
for existing data sources specifically if they are already
being used and have pooled connections. The existing pooled
connections may be in use by the applications too.

Hi, Jonas
Regarding your previous e-mails where you tried to overwrite
META-INF\context.xml.
Please note, that at deployment time this file is copied to
/conf/Catalina/localhost/application_name.xml
I think that you should either update the copy of that file and then
restart Tomcat.
If you
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:
After further tests I found out that the server will reload JNDI data
sources if all the following steps are performed:
1. Change the configuration
2. Execute
Thanks Hassan for your question.
Are these data sources known in advance, or can the configuration
tool user come up with an arbitrary new one at any time?
These data sources will be known at the time of deployment, but as they
are specific for each customer, I cannot write one

Hello,
I'm trying to write a configuration frontend for a webapp. This
application uses several data sources, and it should be possible to
change the username/password/database/... using the configuration
frontend.
My idea was that the configuration servlet would modify the
