Hi Hailong, I have installed JDK and set JAVA_HOME correctly (as far as I know).
Output of java -version is: java version "1.6.0_04" Java(TM) SE Runtime Environment (build 1.6.0_04-b12) Java HotSpot(TM) Server VM (build 10.0-b19, mixed mode) I also have another version installed "1.6.0_27" but get same error with it.
