I am new to Java.. Eclipse etc. We have a working Java application, all the .java files and .class files are available in the file system. The .jar file is executed once a hour and it does it job. Now the developer is gone leaving behind this application.

I dont want to touch the existing set-up. So I have downloaded this Eclipse Standard/SDK Kepler Service Release 2 on my laptop and want to try out some modifications.

After googling "how to open existing java appl in Eclipse" gives very useful info, but none is of use to me. I did File > Import > General etc. etc. but Eclipse keeps saying "No projects are found to import".

In the file system where I have my .java files the project it seems is split into multiple folders, i.e if I open the main source folders, there are 10 sub folders and all contains .java files. I also know from the production environment that all those 10 folders .java files are used.

So I have this .java and .class and .jar file. So how can I import it into Eclipse on my laptop.

    Surely the source code (etc.) is in your source control system? You shouldn't need to "open" the Jar itself. – Oliver Charlesworth Mar 30 '14 at 17:27
  • Honestly, it is _very_ optimistic to think that you can change the application in a useful way with this state of knowledge. If this is a crucial application you need to hire someone to do this. – Hauke Ingmar Schmidt Mar 30 '14 at 17:36
  • @his so what do you suggest, should I quit development and look for alternate career? – half-baked prgrmr Mar 30 '14 at 18:13
  • No! Definitely not. I don't know if you are doing this for learning purposes. Then I have to admit that I think it is a weak approach. You need to learn fundamentals systematically, not by just doing something random. If it is a real task that needs to be done then you can't expect to do it without _prior_ knowledge. I absolutely don't know you personally but from the question it is clear that you _just now_ will not be productive if this is a real task. – Hauke Ingmar Schmidt Mar 30 '14 at 18:54

Probably you have the source code but it's not an eclipse project. Try to see How to create a project from existing source in Eclipse and then find it?
