Eclipse classpath question

In ant, there is a way to set a classpath that includes all .jar files
underneath a particular directory, like this:

- <path id="classpath">
<fileset dir="c:\Programming\Java\jwsdp-1.1"
includes="**/*.jar" />
<dirset dir="c:\Courses\SOAP"
includes="c:\Courses\SOAP" />
</path>

Is there a way to do this with Eclipse? It is inconvenient to individually
specify all the various .jar files that have to be included when doing Web
Services. Thanks

I'm affraid not, but I'd like to hear what other people have to say.

In WSAD (IBM's Eclipse on steroids) you can create a web application and
then put jars in WEB-INF/lib dir which is automatically created. It works
just as expected: all jar files are automatically in the project's
classpath.

If you set up the file structure for a project before creating
the project with eclipse it will import the source and all the jars
that it finds.
With the way I usually set up eclipse projects, for example,
I'll have the project as a root folder with sub-folders for src, lib,
doc, classes (or bin), etc. Put all your files in place then create
the project with eclipse using the project base folder as the project
location for eclipse. Even if you don't have any (or many) source
files, eclipse should pick up the jars under lib (not sure if it will
find zip files).

I am not sure I understand your strategy, so let me take a stab at it:

If I set up a file structure prior to creating the eclipse project, it will
automatically find all .jar files located under the root directory of the
project. This will require me to copy all the .jar files that are located
under the various subdirectories of the Java Web Services Developer Pack
directory. However, if I create my project within the JWSDP directory
(using "src" or something) then it should find all the .jar files underneath
it.

Did I get that right?

    Yes, I guess that I'm saying that eclipse thinks that nothing
exists outside of the project directory. If your jars are scattered
around other parts of the file system then eclipse would not find them
on its own.
    But if you have a bunch of jars in one subdirectory you can
select more than one on the project library wizard. I guess that is
an extra manual step that you are trying to avoid.
    The .classpath file that eclipse creates is simple enough that
a Perl script or something should be able to create one. You could
probably even create it using ant.

I'm not sure with webservices (and I know the **/* works for exclusion
filters), but for similar usage I've just setup a single Eclipse project
to "own" the jar files. Just import and export them, then other projects
can use them by checking that holder project.
