Currently in eclipse when you open a library jar, it shows all the packages and classes, but if you want to see the META-INF content (e.g. manifest.mf), you have to open the file externally (e.g. using winrar)
Is there a simple way buit-in in eclipse to do so, or a plugin that does this?
you can use the Project Explorer view (part of Eclipse Java EE) instead of the Package Explorer view, and view everything inside the jar, including properties files, xmls, etc.
