HELP !!! Very simple code, but failure !!!

hi, i'm a VERY beginner with Httpunit. I was trying to getResponse from 
a site (i.e. www.paypal.com). But it turned out to be a failure :(. I 
think it might have something to do with the javascript (below is the code).

try {

    WebConversation wc = new WebConversation();
    WebResponse   resp = wc.getResponse("http://www.paypal.de");       

} catch (IOException ioe) {
} catch (SAXException se) {}

the error messsage is 'org.mozilla.javascript.EcmaError: TypeError: 
Cannot read property "currentStyle" from undefined (httpunit#16)'.

i use httpunit v.1.7.

thanks in advance,
ferry
