RE: [wtp-dev] How to correctly setup WebProject depencies projects

["Rob Frost" <rfrost@xxxxxxx>]

Hi David,

You're right about this list not containing much user-related traffic;
it is meant for issues related to WTP development/extension. The right
forum in the future for this type of question is the WTP newsgroup.

You need to use the J2EE Module Dependencies UI
(Project->Properties->J2EE Module Dependencies) to created a WEB-INF/lib
dependency between your dynamic web project (ProjectB) and your Java
project (ProjectA).

Adding this dependency will then expose ProjectA on the classpath of
ProjectB via the WTP "Web App Libraries" classpath container (so you
don't need to manually add it to the classpath of ProjectB first) and,
when you publish or export ProjectB, ProjectA will be added as a JAR
inside the WEB-INF/lib directory of ProjectB.

If these hibernate files/classes are referenced from ProjectA via an
exported library cp entry, you'll need to take an additional step after
adding the "J2EE Module Dependency" from ProjectB->ProjectA (that
library cp entry needs to be marked with a special WTP classpath
attribute flagging it for publish/export, see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=184094 for details on how
this can be done via the QuickFix on the problem marker associated with
that library cp entry in ProjectA)

FYI: We are considering some changes for 3.0 that should greatly
simplify the interdependencies beweeen the Java build path and Java EE
module dependencies (i.e. in most cases users will simply be able to
configure the project classpath and the expected module structure will
be generated during publish/export: see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=116856 and
http://wiki.eclipse.org/Web_Tools_Platform_Release_3.0_Requirements/Java
CPvsJavaEEModDeps for more information on that)

-Rob

I can see  there isn't much traffic on this list (as far as questions
actaully being answered).  Is there a better place to get support?  I
have this problem (see below).  I can't see what use WTP is in practice
if you really can't load from the classpath in another project in the
workspace, so I want to believe I am just doing something wrong.  Anyone
got any hints?
