Hi Naval

Go to oracle's download page. Download and install JDK 1.6. Specify your Java home in "path" variable in environment variables as well as path of binaries and libraries i.e. $JAVA_HOME/bin and $JAVA_HOME/lib It should start up then. Let me know in case you face any problems.

Try javaw -version at the command line.

Dear Sir,
I am Doing Work to convert The My Project Code which Was Working On “JDk 1.4 “and I want to Upgrade on “Jdk 1.6.0.38” and I m Working On Eclipse. So I am Confuse Little Bit That
1-Right Now in my system I don’t have any java version, if I installed Only Jre 1.6.0.38 Then It will Enough To Run Eclipse or I have To installed JDK 1.6.0.38?
2-When I installed Only Jre Then Inside of its “bin” There is no “javac” complier .is my eclipse take javac complier from the “JDK‘s bin.?
3-How can I identified that My Eclipse Is Changing the My code from java version 1.4 to 1.6?
4-From where The Eclipse takes Javac compiler To Compile the .java file?

Why? If it works on JDK1.4, why do you need to change it at all?

It says here that Eclipse requires a JRE; I believe it has its own compiler.
