Problems with project references [message #161601]

I set up two projects, one is called "myFramework" and the other one
"MyWebProject". I added "myFramework" as required project in Java Build
Path/Projects. This makes a servlet in "MyWebProject" compile which references
one of the classes in "myFramework".

The problem now is that this project reference isn't used when the project is
deployed into a server (I'm using Tomcat 5.5). I've activated the reference to
"myFramework" in J2EE Module Dependencies and in Project References within the
properties of "MyWebProject". I don't want to copy the myFramework library into
the MyWebProject classpath as this is a hack IMHO as I want the context
MyWebProject getting reloaded whenever something in myFramework or MyWebApp gets
changed.

Am I doing something wrong or is it a bug? I'm using the WTP 1.0 release.

What I forgot to mention: The problem manifests in a "NoClassDefFoundError"
thrown by the JVM that runs Tomcat.

Hi,

You need to indicate which projects are to be deployed in addition to
your "root" (web) project. Do this as follows:
- select the web project in the explorer
- right-click and select the project's properties
- Select "J2EE Module Dependencies" in the left-hand pane
- Select the projects that need to be deployed also.

This at least works some of the time. If it does not work redeploy to
your server or remove and add back the project. Please note that
deployment is very buggy currently (at least with the Tomcat 5.5 server
I use) so remember to redeploy if you notice that the server does not
pick up your changes.

I don't know why this separate page was needed and why it is not
prepopulated with the project's build path but...

Good luck,
Frits

Frits,

Many thanks for your answer! Indeed, redeployment with Tomcat 5.5 is buggy and
doesn't work for me, but I got the dependencies deployed for the first time. The
difference now is that I converted my framework project into a J2EE project as
it was a normal "Java project" before.
