If anyone still wants to know how to properly instantiate ScriptNode from a pure java-backed webscript, here's how:


Context context = Context.enter();
Scriptable scope = context.initStandardObjects();
try
{
     scriptNode = new ScriptNode(nodeRef, services, scope);
}
finally
{
     Context.exit();
}

For more explanation, see https://developer.mozilla.org/en-US/docs/Mozilla/Projects/Rhino/Scopes_and_Contexts

Basically, while the alfresco code supports creating ScripNode instances without a context and scope, many of the ScriptNode methods actually require a context and scope, or they will throw NullpointerExceptions.

This is still true in Alfresco 5
