I have 6 different projects that all use the same resources.
The resources are big jpeg images -- 30 or 40 of them.
Now I have to make a copy of the entire folder and
put it in the src folder so that when I build my app
the resources are copied to the bin folder.
Needless to say, I'm chewing up a lot of disk space having
12 folders with the same resources.
What I want to know is how do I make links; shortcuts; virtual directories
whatever you want to call them so that I just have one folder
full of my images and all the different projects can access the
images in that folder as resources as they need to?
Environment: Eclipse 3.2.1; Windows 2000 SP4; Java 1.5.0.13
How do I make a link to my resource folder? I tried making
a short cut but that didn't work.

In playing around with this, I think there are two different issues that
are potentially confusing. In a vanilla Java project, you set up images
(e.g., images) under your source directory (e.g., MyProject/src/images).
Then, when the build happens, normally this entire directory gets copied
over to the bin (e.g., bin/icons).
So, in this scenario, there are actually two entire copies of the images
directory for each project.
In some quick testing, it is easy to set the src/images to be a linked
directory to some central place on your system. (Just create the folder
as a linked folder.) This avoids the problem of having duplicate image
directories for each project. However, I haven't been able to get rid of
the bin/images directory. You can exclude files from being copied in
there, but then the program, when run inside Eclipse at least, doesn't
find the images at runtime.
So, I think the question is: How does one allow the program to run
inside Eclipse without having the images folder copied to the bin/images
directory? Thanks. Mark

So, here is what I think I've figured out. You can do this at least two
different ways.
(1) Create a class folder (Libraries tab in Java Build Path) in your
project to point to folder with shared files (e.g., images).
or (2) Use a common Eclipse project that has the images folder in it
(e.g., src/images) and then use the Order and Export tab on the common
Eclipse project to add this folder to the list (i.e., check the
src/images folder to make it exported and visible to dependent
projects). Then, for the projects that need this folder, just make them
dependent on the common project (Projects tab in build path).
In my case, I'm using the org.eclipse.swt project as a common project
for all of the SWT and JFace JAR files, so I can just add the images
folder to that project and it all works.
Note that, in either case, you need to make sure that these files are
selected when you create your JAR file. Mark
