J2EE Module Dependencies and build problems [message #215644]

WTP 2.0.1
Windows XP
Dynamic Web Project

Hello:

I am having two problems in WTP.

1) First, when I check off jars in J2EE Module Dependencies it never
sticks. The next time I go there, all my choices are cleared (all
unchecked). This is very aggravating.

2) My JSPs which import classes in jars on the build path will not
resolve. For instance,

<%@ page import="org.apache.struts.Globals" %>

will not resolve even though struts-core.jar is in my build path. The JSP
is in WebContent.

Any help would be appreciated

Hi Eric,

Problem 1 sounds like https://bugs.eclipse.org/bugs/show_bug.cgi?id=205004
(fixed in 2.0.2)

Hope this helps

Thanks, I found that if I select jars individually, they stick. The
"Select All" button will result in the problem.

I am hit by the same problem. Just to recap:

I have a dynamic Web Project and two Java projects A and B,
and B depends on A.

I can successfully add one of the java projects "A" as
JEE module dependency, but If I add the second java project "B"
as JEE module dependency, hit "apply", it is silently dropped the next time
I open the JEE module dependency configuration.

Similarly, if I manually edit

<dependent-module deploy-path="/WEB-INF/lib" handle="module:/resource/org.metware.bigmet/org.metware.bigmet ">
<dependency-type>uses</dependency-type>
</dependent-module>

and change the handle to match the second java project,
the entry is deleted again.

To me the most annoying "feature" is that without a message
even in the error log I have no clue what's going wrong.

I saw quite a few bug reports on JEE module dependency configuration,
and I am somewhat lost in which category mine falls.

What are the requirements for a java project to be a valid JEE dependency ?
What do I have (and not have) to export from the projects A and B ?

I have WTP 3.0.0, and supposedly the above bug was fixed
https://bugs.eclipse.org/bugs/show_bug.cgi?id=205004#c7

The eclipse installation seems to be current,
there are no available updates shown.

Any hints appreciated,
Yours,
Steffen

The following changes in the .project of the project to be included
solved the problem for me, YMMV.

Yours,
