Answer 1

This worked for me too :

1. Go to Window -> Preferences -> Java -> installed JREs
2. Select the JRE you are using (Should be the one inside jdk. Ex: C:\Program Files\Java\jdk1.6.0_25\jre)
3. Press Edit -> Add External JARs...
4. Browse to Java\jdk1.6.0_25\lib and select tools.jar and Press Enter
5. Press Finish and OK
