Unexpected Invocation Exception

Hi,

I'm trying to convert one of the samples (the StockQuote) in the Apache 
SOAP distribution to work as a Java applet. I have setup the class file as 
a OBJECT tag in the HTML file and reference all the required JAR files in 
the codebase. However, I keep getting the exception "Unexpected Invocation 
TargetException" for "java.lang.reflect.InvocationTargetException". This is 
caused by the

  Call call = new Call();

line in the example since a trace just before this line works fine. It is 
not a problem with applet security since the applet and the JAR files are 
hosted on the server which I will connect to and a simple socket connection 
works fine. Also, I make sure that the Xerces is the first entry in the 
CLASSPATH and I tried 1.4.4 as well as 2.0.0. Am i missing any other JAR 
file ? I'm attaching a copy of my HTML page. Just for simplicity, the 
getquote function in the Java file takes no parameters.

<body onLoad="runquote()">

Any thoughts ?
