C:\Users\sarp>java -version
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
However, the applets are not working within browsers(IE, Firefox, Chrome). After a short search I downloaded the version JRE as 1.6.0_14 and browsers start to work with the applets. When I type version of Java, I get this;
C:\Users\sarp>java -version
java version "1.6.0_16"
Java(TM) SE Runtime Environment (build 1.6.0_16-b01)
Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode)
Then if your applets are not working in the browsers of Windows 7 RC, you can try to do what I did to overcome this annoying problem.
