Can someone tell me exactly what is the purpose of "project references" in Eclipse. I'm setting up project dependencies and I'm going through what seems to me a whole ceremony. I'd really like some literature that explains what all these do. I'm seeing alot of literature that says what to do but not why it is done and what it does behind the scenes.
Project Dependencies, Java Build Path/Projects Java Build Path/Order and Export
Also, why in addition to these do I have to add folders in the Server Properties and modify the application.xml?
Nadine, my main use for this is having one or two core projects. The ones that hold all my main business logic and data structures (read beans). Plus all the Hibernate related hbm files.
All my projects then include a core project. These projects then become basically just front ends and controller to implement some functionality. This allows me to:
-Easily add mature code to a new project -Keep the core code in a CVS repository separate from the actual applications. This makes it really easy to modify core code, to work in teams and to quickly propagate these changes throught all projects. -Keep a standard set of data structure and tools throughout my applications -Establish a place to put commonly used code (classes used too often are moved to the core project [Eclipse refactors all references to them])
Hope that helps.

The reason why I was asking these questions is because my problem actually goes deeper. I have (say for the sake of simplicity) 3 projects. myWeb, coreWeb and myEar. Both use struts 1.1 and this jar is in the lib of each project. When I set up project dependencies, there are no build errors, however, I am seeing a runtime error:
RpeRequestProcessor sits in myWeb and extends CoreRequestProcessor which sits in coreWeb. CoreRequestProcessor extends TilesRequestProcessor.
myWeb has Project References to coreWeb, and myEar. myWeb's Java Build Path has coreWeb checked myWeb's Order and Export has struts.jar and coreWeb checked (and in this order)
Hi everyone. I am trying to do the following. Can anybody help?
The scenario that I want is:
Project A produces a JAR file. This can be done using Eclipse or an integrated Ant task.
Project B, C, and D each produce a WAR. They depend on the JAR from project A. If it does not exist, Eclipse will build project A first.
I know how to do it so that the actual .class files from project A will be included in B.war, C.war, and D.war, but this produces bloat that I would like to avoid.
P.S. Because I am running on a new Intel MacBook Pro, I have to use the latest betas of Eclipse IDE and Web Tools Project (WTP). This is 3.2 and 1.5, respectively. Hope that's not a big problem :-) [ April 10, 2006: Message edited by: Matt Solnit ]
