I have refactored a large project into two projects. If I try and start
tomcat in the project w/my JSPs, etc., it can't find the classes from
the other project. So I add that project to the Run definition for the
server, then I get a JDom error: JDomException: NoClassDefFoundError. In
reading around, it appears that this happens when some other XML lib
that is DOM 1.0 (not 2.0) compliant gets in front of xerces.jar in the
classpath. I tried just adding the /WEB-INF/classes dir from the core
project, but same error. I've wasted enough time on this that I could
have just ditched JDom and rewritten my XML routine using dom4j.
Any advice welcome.

The problem I'm having is creating a bean in Spring. The bean's class is
from the included project (not the project I'm trying to start Tomcat
from, the one I added to the Run/Classpath). In this case, it throws
errors. If I move the classes to the /WEB-INF/classes dir, it runs. Is
that what I have to do? Make an ant task to copy changes up from the
dependent projects each time? That would really slow things down.

I have solution for such situation, I've used that projects structure for a
while. Actually I've proposed that structure to team that is working on project
structure, and they tell me that is suppose to be supported (eventually?).
The idea is to modify Tomcat deployment settings and use special class loader
for your application that is able to load classes directly from "bin" folders of
your projects. Solution is simple and work well, I can provide more details if
you still need it...
Best,
Igor Shabalov.

We have the same Problem. Our Prroject Structure is very complex, we have
many Projects wich have dependencies. With the Sysdeo Plugin there is a
Classloader, which can handle Class Folders and Archives, but you have to
set them explizit on the Devloader Page.
It would be helpfull if there where a solution, where the Eclipse
Classpath for the Project and the Project References automatically would
be included to the Apllication Server Classpath.
Because of this Limitation, i have to go back to the Sysdeo Plugin,
because of to much work to Refactor our Projects or do the Builds manually.
