Hello,
I have been happily using Eclipse for a few years but I think I setup my
projects in a "Brute Force" manner. I played around until I got something
to work and did cut and paste to move my .java files to my configuration
management folders from source folders in my projects area.
I am installing version 3.3.2 and decided to use the tool more wisely.
I've played with it for a couple days and remain frustrated.
Let me state my situation and objectives.
Situation:
I am developing 2 Java packages [pk_1 and pk_2] designed for use in Java
Stand=Alone Apps.
Ideally, the code resides in the following folders:
C:/com/pk_1/
C:/com/pk_2/
I also have a folder that contains the .jar files used by one or both of
these packages:
C:/classLibraries/
Objective:
Use Eclipse to develop and test these packages:
What I have been trying to figure out is how to do the following:
1) Create a development project for each Java Package to reference the
above folders and produce a pk_1.jar and pk_1.jar file.
2) Create test projects that use the pk_1.jar and pk_2.jar files as
follows:
a) Project Test pk_1: Stand-Alone program using pk_1.jar.
b) Project Test pk_2: Stand-Alone program using pk_2.jar.
c) Project Test pk_1_2: Stand-Alone program using pk_1.jar and
pk_2.jar.
Note: the .java class used in the above projects would be hosted in the
Eclipse 3.3.2 workspace holder.
I have come close to the setting up one of the packages but the
compilation fails on my "import com.pk_1" statement saying the package was
not a expected.
I'm going around in circles and need some advise.
Regards,
Jim...

When making a new Java project, Eclipse 3.3 will ask you where to put=20
it. You can take C: as a location although I would not recommend it=20
(this is what you are doing now: your Java setup is directly under C:,=20
you have to consider the com/ directory as part of the filename, sort=20
of). I=E2=80=99d recommend you make it C:/workspace or something.
Then, if you use the new class wizard, and give as package=20
com.packageName or class Test, Eclipse will automatically create the=20
directories com/packageName and put a file called Test.java there.
You can then, once you have the new project, import from existing=20
sources; choose the folder C: and check the com/ directory. That should =
do it.
Provided, of course, that your classes in com/pk_1/ all have a=20
declaration =E2=80=98package com.pk_1=E2=80=99.
Note that in the project properties, you can reference other Java=20
projects, which means that for example for the test projects, you don=E2=80=
=99t=20
need to put pk_1.jar in the classpath, but you can refer to the classes=20
directly. Nothing prevents you from including the jar, though.

I doubt this works as this would overlap with the workspace location.

Or simply move your source into its own folder, e.g. c:\source. Then you
can have your eclipse workspace anywhere on C:, create a Java project
and then add a source folder that links to c:\source.
