As an example, current case — I try to install GlassFish adapter in Eclipse. It fails, because it requires “org.eclipse.jst.j2ee.web 0.0.0”.

How can I figure out from the class (?) name which package I have to install? When I select Eclipse repository and search for “jst” I got 3 hits (from memory: JST Server Adapters, JST Server Adapters Extensions, and JST Server UI — all 3 are now installed, and the requirement is still not met).

Please note, this is just example — the question is not how to install GF, but how decode class (?) name into package.

    If the dependency isn’t automatically determined, then I end up searching Google for the required dependencies of the plugin. Another way is to search for the class name and determining what Eclipse package that class is in. I really don’t think there is any better way, other then guessing.

    For example, I entered org.eclipse.jst.j2ee.web into Google and ended at the WPT project page. Clicking around there I ended up the Java EE Tools page, and then the component overview page, which ultimately shows the package in question. I would then suspect that “Java EE Tools” is the Eclipse plugin that needs to be installed because of this text:

    The Java EE project is comprised of jst.common , jst.j2ee , jst.servlet , jst.ejb , and jst.web subprojects. The following diagram visualizes the dependencies among these components, and the relevant WST subcomponent dependencies.

    However, it appears Eclipse itself calls this “Eclipse Java EE Developer Tools” instead.

    It’s a headache, I am not going to argue that.
