Greetings Guys.
I am using Rhino as part of my HttpUnit. Pretty much I just started this testing effort on an already developed and production J2EE project.

Here is the Exception

org.mozilla.javascript.EcmaError: TypeError: Cannot find function createElement.

(httpunit#418)

Our JSPs have pretty good bunch of java scripts. In this particular case, I have a JSP including another jsp. This included JSP has few scripts, some of them are triggered on body onload event. Now, when I get to this page response through HttpUnit Request/Respnses, I am getting this exception.

The script extract:
function appInfoUserSelections()
{
------
var element = document.*createElement*("option");
-----
}

This line is throwing this exception.

I have seen somewhere Rhino supports Javascript Standards... I do not see this _createElement _method in any of these Javascript (ECMA) standards. However, this method is introduced into DOM level1. Does Rhino supports DOM-flavored Javascripts?

If it supports, then can anyone help me pass through this Exception?
If not, any suggestions is appreciated. Since I am stuck here for about couple days besides doing some other work.


Testing/Dev Environment:
Downloaded HttpUnit a month ago, using Eclipse 3.2 IDE, created TestCases through this; I have the following jars in the testing project library: junit3.8.1.jar, httpunit.jar, js-1.6R5.jar, nekhohtml-0.9.5.jar, xercesImpl-2.6.1.jar, xmlParserAPIs-2.6.1.jar. Out of which junit3.8.1.jar comes with Eclipse testing plugins itself I believe.

Thanks for your time.
