How / where do you search for installed java libraries on your computer / project?

I don't have a good understanding about how Java and Eclipse (more specifically, Enfinity) arrange their project files. I'm part of a team at my office which working on a project which continuing the working of many other past members of the team. Many of the original people who worked for this project on the earlier days is already not here, so I can't ask them, or ask anybody else.

Here's the problem: I need to understand how a class is working before I can find what's wrong with the result. But after some tracking with Java decompiler (jd-gui), I'm stuck to a class that's referred on the line import de.factfinder.search.Search;. I can't find that anywhere. If you're debugging on an unfamiliar computer using Java decompiler, and you find an import reference to a class like this, where would you suggest to start looking? What filename it might be contained on?

Note for Enfinity users: I've also already searched thoroughly on the folder that has bc_foundation and friends, where usually Enfinity proprietary classes stored and I can't find what I'm looking for.

Solution

Assuming that the library is already configured in your project. Then, you could try to search the class through "Open Type" dialog which accessible via shortcut ctrl + shift + t.

On the dialog, you then search the class by typing its name (in this case de.factfinder.search.Search) and then you can look at the bottom text area where the package is.

Example is like this, let say I want to search Entity annotation where the jar file is.
