Hi,
I have been working with eclipse from the last week. It was all working fine.I was doing small example programs.Yesterday when I ran a program I got this NullPointerException.I tried to see if I had done any mistake in the coding...but it was all fine, moreover all my old programs which were working fine are also showing the same error
"Exception in thread "main" java.lang.NullPointerException"
at Javax.swing.JMenu.add(JMenu.java.548) when I click on the above, it shows
Source Not Found - The jar file rt.jar has no source attachment. It also says you can attach the source by clicking attach source below : An Attach Source button.
Can anybody clarify the exact steps to rectify this problem??
Thanks
