I have a jar file that contains source code. How can I browse this source code in Eclipse?

At the moment, my Eclipse opens the jar file in a Text Editor, and it isn’t that helpful.

When I look in the preferences “General” > “Editors” > “File Associations” I have no associations for *.jar and if I look in the available “Editors” I can’t find anyone that seem to be a good fit for jar files.

How can I browse the source code in a jar file using Eclipse? Is there any Editor I should configure for jar files?

    Extract the jar in some source directory (it’s a zip file), and create a project with this directory as source.

    Or, if this source jar file contains the sources of a classes jar file that is used as a library in your Eclipse project, just right-click on this jar file, select “Properties”, then “Java Source Attachment”, then “External File”, and select the source jar file. Then each time you browse a class from this classes jar file, Eclipse will automatically show you its source code.
