JFace outside eclipse still needs eclipse core runtime? [message #463896]

Originally posted by: brigitte.ilsanker.gi-de.com

I'm trying to develop a standalone application, which should be a wizard
that users can use as a GUI without using Eclipse.

I understand from the documentation and from the article
"Developing JFace wizards Using the JFace toolkit" by Jeff Gunter found at
the IBM site
http://www-128.ibm.com/developerworks/java/library/os-ecjfw

that this should be possible.

Now I try to run the example provided at that site with the following
Error:
java.lang.NoClassDefFoundError: org/eclipse/core/runtime/IProgressMonitor

This sounds to me, that I do need eclipse core runtime classes. Is that
true?
Or do I simply use an outdated example and should change to newer
resources? If so, where to find it (I searched the eclipse site already
and even IBM's).

You don't need to run eclipse, but you do need the runtime jar in your
classpath (org.eclipse.core.runtime_XXX.jar). Or you could extract the
that class from the runtime jar ... It doesn't seem to have any other
dependancies on runtime.

That's the quick fix. You can also open a
https://bugs.eclipse.org/bugs/ against Platform/UI and ask about the
dependancy.

And lastly, I'm moving this to eclipse.platform, they work on JFace.

It is strange.. I have tried it with 3.1 not so long ago and it worked
only with swt and jface libraries.. No other were neccesary.

Cheers,
Radek.

It'll only show up if you use a JFace class that refers to the
IProgressMonitor ... otherwise the JVM will never try and load the class.

You can add yourself to the cc list of
https://bugs.eclipse.org/bugs/show_bug.cgi?id=49497 - a subset of the
core.runtime classes will be available as a separate JAR soon.

Today, in fact. In I20051122 there remains only one JFace dependency
outside the small (65KB) org.eclipse.equinox.common plugin. See:

As of N20051124-0010 and later, you need to add the following to your
classpath to run JFace standalone. Note that you need an SWT JAR that is
appropriate for your operating system and widget tool kit. The sizes are
approximate, and the "version" will vary from release to release.

729K org.eclipse.jface_version.jar
1.5M org.eclipse.swt.gtk.linux.x86_version.jar
4.0K org.eclipse.swt_version.jar
76K org.eclipse.core.commands_version.jar
64K org.eclipse.equinox.common_version.jar

There is no longer any dependency on the "org.eclipse.core.runtime" plug-in.

cheers,
d.
