Problem: Applets cannot Create SOAP Message Objects using JAX Pack

Question

Hi all
I want to invoke a simple webservice located at a url.
I wish to send a SOAP Message . The Message is creating using
javax.xml.soap package
Here is the code
public void init(){
try{
MessageFactory MF = MessageFactory.newInstance();
SOAPMessage message = MF.createMessage();
SOAPPart SP = message.getSOAPPart();
SOAPEnvelope SE = SP.getEnvelope();
SOAPHeader SH = SE.getHeader();
SOAPBody SB = SE.getBody();
Name bodyName = SE.createName
("testString","L","http://tempuri.org/");
SOAPBodyElement SBE = SB.addBodyElement(bodyName);
}catch(Exception e){}
When I run the applet in a browser I am getting ExceptionInInitializerError or NullPointer Exception.
The same application works when i run as a standalone application. But not in APPLET.
Can somebody help me in this regard

Answer 1

Im trying to do the same thing !!, i have a servlet that processes SOAP messages, and return SOAP messages back.
Like you i have a implementation running with a stand alone client instead of an applet, which runs fine (there are several .jar files that have to be included in the jre/lib/ext directory, in total about a meg!).
Im now looking to incorporate this client into an applet, but it moans about cannot find classes (the JAXM and SOAP classes).
Have you found a solution to this yet ?? Surely you cannot expect the user to download all the required jar files along with the applet??
With regards to your problem try setting up a button that fires off the SOAP Msg and processes the response, i read on the Sun Java Applet tutorials that some code should stay out of the init method(its a bit vague about WHAT should stay out..), maybe this is an example.
Thanks,
(i dont really expect a response as you posted this ages ago !!, but it would be nice.)
