Eclipse is running in a JRE, but a JDK is required

Hi,
1) Right click on windows eclipse shortcut.
2) add in the end of the Target "-vm pathtojdkliberary"
3) Ensure that the JRE library is setup correctly within eclipse->preferences->JRE
Solution refers both to MyEclipse (not matter if its the Blue version or the regular) and Eclipse.
That's it.
