Tips: the steps 5-10 are not suit for my eclipse.no JVM Contents (MacOS X Default) ,only Standard Jre Environment option and I can't choose the dirctory that the java runtime directory installed.

fixed idea: as the java standard content is hidden in the mac jdk library , so we can't choose the Java home dircytory dircectly.so we should soft link the java home directory to another reachable place.

such as ln -s /Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home  ~/JDK_HOME

then we can add the mac JRE environment like the  standard JRE environment.

good luck every one!

 

 

   You can download the 10.7 Lion JDK from http://connect.apple.com.

 

1. Sign in and click the java section on the right.

2. The jdk is installed into a different location then previous. This will result in IDEs (such as Eclipse) being unable to locate source code and javadocs.

3. At the time of writing the JDK ended up here:

   /Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home

4. Open up eclipse preferences and go to Java --> Installed JREs page

5. Rather than use the "JVM Contents (MacOS X Default) we will need to use the JDK location

6. At the time of writing Search is not aware of the new JDK location; we we will need to click on theAdd button

7. From the Add JRE wizard choose "MacOS X VM" for the JRE Type

8. For the JRE Definition Page we need to fill in the following:

   • JRE Home: /Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home

9. The other fields will now auto fill, with the default JRE name being "Home". You can quickly correct this to something more meaningful:

   • JRE name: System JDK

10. Finish the wizard and return to the Installed JREs page

11. Choose "System JDK" from the list

12. You can now develop normally with:

    • javadocs correctly shown for base classes
    • source code correctly shown when debugging
