| Access jar file outside plugin directory [message #206349] |

I have a standalone Java application that is installed in its own
directory, let's say C:\Program Files\Java\foo.jar. Now I want to create
a simple Eclipse plug-in that adds a menu item to launch the application.
The problem is that I can't just specify foo.jar to be included in the
class path under the "Runtime" tab of the plugin.xml file since foo.jar
doesn't reside in the same directory. So I tried to specify "C:\Program
Files\Java\foo.jar", and it still can't find the main class to call. What
should I do? Thanks!
Regards,
Michael

Rich,
So there just isn't a way to add the external jar to the classpath? Like
by modifying the environment variable or a config file or something to set
that classpath when Eclipse first starts? That seems to be quite a
limitation. If someone has an application installed anywhere in the
system and has a config file that tells me where the jar file is, I should
be able to load that jar and call "Foo f = new Foo()" without having to
create a separate Java process. The plugin jar should only deal with the
logic of integration with Eclipse workbench, and the plugin directory
shouldn't need to contain the application jar files. Otherwise, if the
standalone version is updated, my plugin will be out of sync. Creating
symbolic link isn't ideal either.
Launching it by calling main with a separate process denies me tighter
integration with Eclipse. Let say in my standalone application, I have
some pretty cool views, and they are in classes Bar1View.java,
Bar2View.java, Bar3View.java. So I want to put them together in a
Perspective, then I will need to call "new Bar1View()", "new Bar2View()",
etc., but that shouldn't require me to have the jar file that contains
these views in the plugin directory.

First, there are already two bugreports related to this problem
https://bugs.eclipse.org/bugs/show_bug.cgi?id=3074
https://bugs.eclipse.org/bugs/show_bug.cgi?id=30919
Second, there is a trick/solution that should work with latest 3.0
builds which was suggested on this group few weeks ago. Basically, the
idea is to dynamically install fragment/plugin that will be "located"
together with the external application.
