Hi.
I am trying to create new ASTParser:
ASTParser parser = ASTParser.newParser(AST.JLS3);
I get error bellow. I included org.ecilpse.core.runtime_3.3.100.v....jar
in buildpath. When I try to import org.eclipse.core.runtime.jobs it
doesn't seem to exist. What else is going on?

Alex,

It's in org.eclipse.core.jobs*.jar.

Ah thanks, found it. I have another question where can I download:
org.osgi.service.prefs. When I tried to create new ASTParser it gives me "
java.lang.NoClassDefFoundError: org/osgi/service/prefs/Preferences" error.
I looked in to plugins folder of Eclipse, but the jar file is not there.

Thanks.

Alex,

The way that I answer questions like this is I use ctrl-shift-T, enter
the name Preferences, select the correct one, and use the little left
right arrow in the navigator to select it the opened file in the tree.
This tells me it's in org.eclipse.equinox.preferences*.jar. This
technique relies on some plugin having a dependency on it. There's some
magical PDE technique that I've forgotten which creates a hidden project
that depends on all plugins and hence makes this technique work even
better. Maybe someone like Chris will remind me of the trick...
