Subject Re: Understanding context.xml
Date Mon, 02 Nov 2009 13:47:40 GMT
Oh, Thanks a lot, I would have never guessed that it is a bug in tomcat. But I would like to
ask a follow up question.

If I change the testprojekt.xml in conf/Catalina/localhost/testprojekt.xml my webapplication
will be redeployed (assuming the bug is fixed), and it would get the new values. If I change
the conf/context.xml all my webapps will be RELOADED, but new values and changes to values
in conf/context.xml will not be given to the webapp.

I am using the tomcat connection pooling to connect to a postgres DB, I would like to put
the configuration (hostname, username, etc) somewhere, so that i can change it, when I change
the databasehost. Where is the right place to put such a configuration?

If i put the configuration in conf/context.xml the changes to the values wont be given to
running applications.

If i put it in the conf/Catalina/.... the application will be redeployed, which causes downtimes.

What is the right place to PUT and later change the connection infos to the database?

Thank you again for your help.
Regards,
Carsten Pohl
