Please make sue that you have set your environment variables correctly and the correct JDK is selected.

Give a try with changing the "Java Compliance Level" to 1.4 in the IDE.

To set the "Java Compliance Level" to 1.4., in Eclipse Go to Project -> Properties -> Java compiler, enable "project specific settings" and then set "Java Compliance Level" to 1.4.

Regards
Gopal
