Subject RE: R: Form Authentication against JNDI Datasource Realm
Date Wed, 12 Apr 2006 15:38:37 GMT
I suspect from the error msg that your server.xml is non well-formed somewhere, has a syntax
error or bad class name. Try checking through it, or comparing it to a fresh server.xml from
a Tomcat distro. Frustrating, but that's all it will be I think. Not sure if the carriage
return is allowed or not in the value here ..

I'm thinking about Connector/J jar file.. but it's in the right location..

I'm getting crazy and I have no IDEA!!! better to shut down and go home...

The server.xml is looking for Windows like server.xml for all other OS. 
Tomcat is written in pure Java, so mostly is looking the same in any 
operating system.
I give you a working example with a postgres implementation and you can 
try to make it run on your machine:
