Answer 1

I am curious to know if it's jar why do you want to import as a project? You can import external jar as a "APP Client Jar File" which is under Java EE. I tried this with your attached jar and I am able to import it and able to see the content in it.

You cannot recover the project. You did not set to export source files while exporting, there are only .class files.

For future reference select Export Java source file and resources while exporting the project.

You are mixing a few things. If you deleted your project source you won't be able to recover it unless you decompile it, and it will be obfuscated even though.

What you have is the compiled project, resulting from taking your source (.java) and compiling it to .class files.

The Import option in Eclipse is made for importing .project files, that hold your project's information. Also you could create a new project from your existing code but as far as I know you just can't create/recover a project from it's compiled jar.
