So, here's what the VCO 4.1 developer's guide says about accessing java classes from Orchestrator's javascript...
h5. Accessing Java Classes from JavaScript
By default, Orchestrator restricts JavaScript access to a limited set of Java classes. If you require JavaScript
access to a wider range of Java classes, you must set an Orchestrator system property to allow this access.
By default, the Orchestrator JavaScript engine can access only the classes in the java.util.* package.
The Orchestrator administrator can allow access to other Java classes from JavaScript functions by setting a
system property. See the VMware vCenter Orchestrator Administration Guide for information about setting system
properties.
(http://vmware.ie/pdf/vco_410_developers_guide.pdf, pp. 115).
This is less-than helpful as it doesn't actually say how to use java classes from javascript.
After following the instructions for access java classes from javascript in the VCO administrator's guide (http://vmware.ie/pdf/vco_410_admin_guide.pdf, pp. 67) I am still unable to use standard java classes. Does anyone have any examples of how to do this? I've tried "inetAddress = java.net.InetAddress.getByName(serverAddress);" and I get the error "TypeError: getByName is not a function, it is org.mozilla.javascript.NativeJavaPackage." I've also tried using Rhino's importPackage function and it doesn't seem to be recognized.
