Issue with JNDI datasources in Tomcat 6
Hi,
I'm trying to use JNDI datasources in Tomcat 6, using global naming
resources. My setup is identical to this one:
http://pro-programmers.blogspot.com/2008/07/spring-datasource-jndi-lookup-from.html
But I keep getting null when doing the lookup. I debugged the code a little
and the problem seems to be that the entry for the datasource in the naming
context does not have an address element. Any tip as to what I might be
doing wrong?
Thanks.

Try the real docs:

Most likely a configuration problem. Since you haven't shown us any of
your configuration files, it is impossible to help further.

Hi, I based myself on a Tomcat 5.5 tutorial because that's what I found on
the net. I did put the driver jar file in the lib/ directory, which is the
place it belongs. I can see the datasources using lambda probe and if I
debug the code the datasources are there, but the ref address of the JNDI
entry that's resolved is empty and so it can't find the actual object.
Thanks again.

You said you set that up exactly as done in the link below, and the link below shows this near the top:
Figure: Tomcat 5.5 directory structure
DB_Driver.jar
Question - if you're on Tomcat 6 series, why are you configuring to the 5.5 specs? I'm thinking they're done a bit differently.
Maybe Chris, Pid or Chuck could verify this, but I think I'm correct here.
Do you have the proper .jar file in the correct folder?
