Hey

I'm used to using a Mac and I've done a lot of work with Java, but I can never seem to figure out how to configure Java IDEs on my Macs. I work with Windows at my school and I'm easily able to install and configure IDEs such as NetBeans, XCode, and JCreator, but when it comes to using my personal Black MacBook (OSX 10.5.8, 2.4 GHz, 2 GB) I get lost. I install the IDE, open it, and then try to build my programs and run them and it always tells me that it can't find where the Java code is on my computer.

I feel really stupid asking all of this, as I'm extremely computer literate, but this has evaded me for too long, so I need help.

Specifically, how do I route the IDE to find the JDK at a specific location (assume I'm using XCode, just for ease).

Thanks

You shouldn't have to "set up" Java at all. A JDK (actually, several) is included with OS X. By default, it's at
/System/Library/Frameworks/JavaVM.framework
On Leopard, the default is 1.5, but everything from 1.3 to 1.6 is installed.
Most every IDE will know this and require no configuration.

NetBeans will pick this right up. If you install it, Choose Tools > Java Platforms... and it will show you the default. If you click on Add Platform.... it will show you the others.
In Eclipse, open Preferences, and go to Java > Installed JREs.

(JCreator is Windows-only...which never really made sense to me...)

what IDE are you using?

personally i think eclipse is the best available IDE for java programing on macs, net beans a lil behind. both of these will find the java JDK and necessary resources, as ^ said. However, as ^ said, there are a couple versions installed, so you may need to select which one from a drop down menu (at least this is how it is in eclipse)

DO NOT use xcode for java programming, simply because it really isn't meant for it and isn't maintained well (defaults with java 1.3 for compiling i believe)
