I'm trying to use spring from a Dynamic Web Application and I have
difficulties to get all needed jars in .deployables.
I've added spring.jar to the build path, but it is not added to
..deployables. Spring is no jar dependency from another project, so I
cannot configure it as jar dependency.
Is a dynamic web project not supposed to put all libraries needed by the
project into deployables?
How should I proceed to get spring.jar into my web project?
Regards,

Did you put it in WEB-INF/lib/ ?

I can see the rationale here, since WTP might be called on to actually
perform a build. But a requirement to physically copy a library into a
project conflicts with our company's practice of keeping one copy of a
library to be shared among dozens of independent projects.
Is there a way to add some sort of link to the /WEB-INF/lib directory
rather than actually copying a JAR? This would tell WTP where to find
the actual JAR file when building a WAR, but let people continue to
manage their external dependencies ... externally.

Yes, some sort of a library manager like the user libraries could be
more intelligent.

What we actually need is a function akin to the Library Export for
projects.
This could be implemented as a tab inside of the Java Build Path property
page called "deployed libs" with checkboxes next to all of the libs.
This would allow you to add libraries to a single project. This opens up
a seperate issue, that of "library projects". Although these are relative
more to JDT than WTP, they become more important for WTP.
-
A quick way of solving library issues within some companies is to share a
common directory with many libraries. You use source controle to get the
latest version of all libraries at once. This guarantees that two
in-house projects or more are not using the same library. This also
reduces sync-time with large libraries over slow networks.
Having a specific <java> project type that does not expect source code,
but only libraries could simplify this.
-
Another problem that this doesn't solve is that some libraries you want in
your app server, some in your ear, and some in your war. Your Ear project
depends on your war, but not the other way around, so adding a library to
your EAR project or to your server does not help eclipse compile your war.
You either have to make a round trip dependency, or add the lib manually
to the project. There should be an intrinsic way for the war to say "I am
part of this EAR, the EAR has the lib, I have the lib".
