Hi,

I’m used to running MyEclipse in windows platform, but now I’m changing to Mac OS platform.

How can I update the Installed JRE?
I would like to have JDK1.6.0_07 in my JRE, which version of JDK should I download for Mac OS?

I just updated to Java for Mac OS X 10.5 Update 1 which have Java SE 6 version 1.6.0_05, but I’m not sure how can I add into the installed JRE or how can I have version 1.6.0_07

Can someone help me with this.

Thanks

The version of Java on Mac is provided directly by Apple, there is no update besides the one to download from any other site (e.g. Sun, IBM or otherwise).

If 1.6.0_05 is what the system updater installed, that’s the latest release from Apple then.

Thanks,

Do you have any suggestion on how can I downgrade my project? (sounds silly, but I want to try to build it under Mac OS)

I have my web project build under 1.6.0_07 how can I make it compatible with 1.6.0_05 ?

Thanks,

Geek,

The compiler that is actually compiling your project isn’t the one for the JRE you have set on your build path, it’s the internal Eclipse JDT Compiler, so you can set compiler compliance leves (Java 1.4, 5, 6, 7, etc.) under your project properties and Java Compiler preferences.

If you are having build errors because of the missing JRE not available on Mac, you just need to go to your project properties and go to Java Build Path then > Libraries and remove the JRE there and click “Add Library” then select JRE and add the default JRE.

You can’t downgrading your project really, you just need to provide it a full JRE to resolve it’s compile dependencies again, you cannot control building class files to that specific of a level, only to the major Java version (Java 1.4, 5.0, 6.0, 7.0, etc.)
