You also have this eclipse plugin: jarclassfinder

The user enters the name of the class not found (or the name of the class that the Java project needs to access). The plug-in will search the selected directory (and subdirectories) for JAR files containing that class.

All results are displayed in a table in a custom view. The user can then browse this table and select the JAR file to add to his Java project's build path. The user then right-clicks on the entry in the table and, from the context menu, selects the build path to which to add it.

Update 2013, as I mention in "searching through .jar files eclipse", it is no longer maintained, and the alternatives are sparse.

As sunleo comments below:

with Eclipse, Ctfl+Shift+T remains the easiest alternative to look for a type
(with the jar name displayed in the status bar).

For mac, it is cmd+shift+T in Eclipse to find the class and associated jar.
