Hi,

There is a versions conflicts in the JDK version.

Can you check which JDk version your using and also make sure that the NWDS insttalable should match the correct

JDK version.

EX:If you are using NWDS 7.0, which supports JDK 1.4

If requires,Upgrade the Java development kit (JDK) to version 1.5 or higher
