Hi all, Just a quick question. Can you set system properties from a Java Application? For example I want to set the JAVA_HOME property, how would this be done? I know there is a, System.setProperty() But how is this used? Thanks, Patrick

You can change some properties local to java, but the change isn't permanent - it only lasts while the java app is running. It's like changing environment variables in a batch file - when the file is done running and the command window it launces exits, those settings get undone. Setting JAVA_HOME would require some kind of access to the native environment variables - I don't think you can do this without using JNI, and then of course it's not portable.
