My program needs extra JARs in its classpath (I'm using XML Stax

build path. However even when I add the jars to the runtime dependancies
section of my plugin.xml, running my program as an RCP application still
complains of (provider com.bea.xml.stream.MXParserFactory not found)
even though it's in one of the JARs I provided as a dependancy?
Anyone got any ideas?
Kevin.

Did you select the jars for the Source or Binary build? I would suspect
they should be selected for the Binary build.
Also, how can you use classes at runtime that you dont at compile time?
Only way I can think of is to use the class name and instantiate it?

Hmmm, can you enter a bug report in Platform>Runtime with this info. Also,
if you would, include the manifest file that we generate for your plugin.
It should be in
<install
location> /eclipse/configuration/org.eclipse.osgi/manifests/GraphEdit_ 0.0.0.m
f
or some such. If you want do some inspection there, all the packages that
you are looking for should be "provided" in the manifest.
Also, I am a little unclear what you mean by "tester methods" and "running
your RCP application". When you are "testing" are you running an Eclipse
instance or just a Java program?
Please ensure that you are using -clean on the command line when launching
your RCP application. This will toss and regen any cached info (e.g.,
generated manifest files).

Finally, a solution that worked. Thank you so much :)
