What's it about: com.vmware.scripting.javascript.allow-native-object

Hi!

When playing around with java.util.*-classes (see http://communities.vmware.com/message/1808053#1808053 ), I recognized following log entry in server.log (server set to loglevel "ALL"):

2011-08-09 12:22:35.532+0200 DEBUG [MainScriptingObject] Found 'com.vmware.scripting.javascript.allow-native-object' property to false, java class usage removed from scripting

Any ideas, what this means?

BTW: If you set it to true in vmo.properties, the log-entry changes correspondingly, but the only change in behaviour I found when working with java.io.File-Objects.

Thanks in advance!

Regards,

Joerg

This property is used to filter Java classes that are visible to scripts. For more information, try googling for ClassShutter (for example, the javadoc for this interface is listed here http://www.jarvana.com/jarvana/view/rhino/js/1.6R6-candidate2/js-1.6R6-candidate2-javadoc.jar!/org/mozilla/javascript/ClassShutter.html

Logic in our code is the following:

if (property "com.vmware.scripting.javascript.allow-native-object" is false)
{
    if (property "com.vmware.scripting.rhino-class-shutter-file" defines a valid file name) {
        load shutters from this file
    } else {
        load shutters from file 'PatternClassShutter.list' // currently, this file contains one line - java.util.*
    }
    Context.getCurrentContext().setClassShutter(shutters loaded above);
} else {
    // no shutters defined
}

Hope this helps,

Ilian

The jarvana website is off-loaded now. If possible, update the link.
