This is a short instruction on how to install and run the BEA WebLogic Network Gatekeeper on Mac OS X.
If you try to run the generic WLNG installer without any arguments you will receive an error that states "Insufficient disk space", even if you have enough space on your disc.

The error will look something like this:

Insufficient disk space during installation

The generic installation package should be used in this case, but the trick is to specify Unix as OS name when installing WLNG.
Run the following command in a shell:
java -Dos.name=unix -jar wlng300_generic.jar

After the installation is completed you should increase the Java memory allocated to be able to run the WLNG server.
This can be done by running the following command before calling ./startWebLogic.sh in $DOMAIN_HOME/bin:
export USER_MEM_ARGS="-Xms256m -Xmx512m -XX:MaxPermSize=128m"
It could also be done by updating the MEM_ARGS environment variable in the $DOMAIN_HOME/bin/setDomainEnv.sh file instead.

The WLNG server should now be started and it should be possible to access it via http://localhost:8001/console/

Eclipse, WLNG Extension Toolkit.

If you want to use the Eclipse plugin you might have to do the following changes to be able to configure the plugin.
In the properties for the plugin you have to specify the JDK and for some reason the plugin must have a tools.jar file present in the lib directory otherwise it will not think it is a valid JDK, but there is no such file in Mac OS X JDK.
The configuration could however be tricked by adding a file to a created JRE directory and point to that directory in the plugin properties.
export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.5/Home
sudo mkdir $JAVA_HOME/jre
sudo mkdir $JAVA_HOME/jre/lib
sudo touch $JAVA_HOME/jre/lib/tools.jar

I hope these instructions has helped you with the installation of WLNG on the Mac OS X platform.
