Anybody have any idea why I’d get a “not bound in this context” error on a dev Tomcat server but not on my local box?
Everything is the same: web.xml, jsp file, and my Resource/ResourceParam definitions. The jsp runs on my local Tomcat, but not on the dev server. Same version of Java and Tomcat.
It’s one of those problems where a guy I work with has given up on the problem and my boss has asked me to look at it. It’s a project/client I’m not even working with/for but the jsp is very basic. Bad design, but basic.
The point is that it works on one machine and on the other the same code generates a “not bound in this context error”. I’ll paste the exception below the jsp. Again, I’m just trying to figure out why this will run on one instance of Tomcat and not on another.
