Hi Snjezana,
Ok, I can verify that the tools.jar file exists. Below is the directory that i found:
C:\Program Files\Java\jdk1.6.0_01\lib\tools.jar
Also, i didn't seem to have any space characters appended at the end of JAVA_HOME environment variable value. But just to be sure, i deleted it and re-typed it back in. it now shows:
Variable name: JAVA_HOME
Variable value: C:\Program Files\Java\jdk1.6.0_01
