I have JDK 7 and eclipse JUNO installed on my windows 7 system .Both of them are working fine and eclipse is very well compiling my Java apps and running them as well .

But when I roll-over my cursor on syntax,then it is not showing its description.It says :

This element has no attached source and the Javadoc could not be found in the attached Javadoc.

for every element.
I could not find anything useful on the google and also there is no similar post on StackOverflow.

What is the problem?

    If you only have JRE’s installed, you need to install a JDK first (find it here), then in Eclipse go to Windows>Preferences>Java>Installed JREs and add your JDK there. Then you can add it as a library in your project settings (in the screenshot above)…
