Re: [Jython-users] How can one propagate "System" property to JVM from jython command line ?

[brian z. <bz...@zi...>]

Stuart,

Looking at the sourcecode, here's why it doesn't work (this method eventually gets called for -D's):

    public void setProperty(String key, String value) {
        properties.put(key, value);
        // This only works for Java 1.2.  There appears to be no portable
        // way to support this under Java 1.1
//         try {
//             System.setProperty(key, value);
//         }
//         catch (SecurityException e) {}
    }


Notice it does not set the System property because of the noted comment.  You could optionally change the batch/shell script you use to invoke the jython interpreter to pass the -D arguments to the JVM as opposed to the PVM (the way you are doing it) and then the properties will be available to you.  Hope this helps...
