In a tomcat instance (6.0.13) with multiple apps, how do can I easily

Shouldn't your connection URL look something like this:
jdbc:mysql//db:3306/apacheSSO instead of jdbc:mysql://db/apacheSSO? Not
sure if this means anything, since you say it's already working... It just
looks strange.

You may want to try it with explicit values to see if that makes a

Hi,
We have four web applications that deployed on Tomcat 6.0 at the same
time. Some special customers want to use special context paths to access
them, so I think the easiest way is to use context.xml to define the
context paths.
I do not know how to do it? Can you kindly give me a

This expression should be ${sbean.totProgrammi gt 0} or
${sbean.totProgrammi gt; 0} as the '' character is probably messing up
the parsing.
