I've spent the last couple of days familiarizing myself with the new 5.0.19, especially the JNDI connection pooling. I tried, unsuccessfully, to use the admin console to set up JDNI datasources as well as editing the xml files directly following the instructions in the documentation. The only way I was able to get the connection pooling to work was to manually create a context in the server.xml and add the resources there. This worked great. The documentation for Tomcat 5 looks suspiciously like the Tomcat 4 so I think it is not updated yet.

Doug, I really hope someone will shed some light on this, because I struggle to make my JNDI DataSource definition working properly with 5.0.19. And it seems the Resources still need to be defined in the server.xml even if the documentation for 5.0.19 is saying you should no longer put your Context definitions in the server.xml, but rather in the context.xml in the META-INF directory packaged with your application. It is supposed to make possible changes in the context without having to restart Tomcat. But, I was not able to make this working as documented... ;-( Since I am a newbie, I sticked as much as possible on the instructions. But, it seems not to work as documented.
