Apache SOAP client in IE Browser
Hello,
We are planning a process control system using a
standard browser for the user interaction. To enhance
the functionality of this browser, we plan to send it
an initial page and then keep that page up-to-date
using DHTML. Thus the user will see incremental
changes in the brower window as the process proceeds
but will not be confronted with the full page replots
that a CGI implementation would require. We are
excited about the possibility of using SOAP to
exchange information between the broswer and a web
server connected to the computers on which the process
is occurring.
Our proposed configuration is this:
* Server: Apache with mod-perl using either soap.pm or
soap-lite.pm. Perl fits with our other efforts on this
computer and is a natural for obtaining and processing
the kind of information we need. We have demonstrated
that this side can be done.
* Browser: The DHTML work will be in Javascript. We
anticipate updating the system information around once
a second so will need to do this interaction in a
different thread. Here we believe a Java SOAP applet
is a natural.
My problem is that I haven't succeeded in pasting
together the right sequence of calls etc. to make this
happen. The parameters required for input are
particularly puzzling.
Does somebody have a simple working applet example
(preferably one that connects to an existing web-based
service so that we can work on one side at a time)?
Thanks,
Keith

Keith,
Here is a sample, but it looks just like the AddressBook sample code. The
only thing different is the standard Java Applet setup. I am using a Java
Servlet setup on the server side.
Cory
/* Build the SOAP call.*/
soapCall = new Call();
soapCall.setTargetObjectURI("urn:XmldsTestQuery");
soapCall.setMethodName("runQuery");
soapCall.setEncodingStyleURI(Constants.NS_URI_LITERAL_XML);
/* Invoke the SOAP call.*/
try
{
soapResponse = soapCall.invoke(url, "");
}
catch (SOAPException e)
{
System.err.println("Caught SOAPException (" +
e.getFaultCode() + "): " +
e.getMessage());
return;
}
/* Get the SOAP Response.*/
if (!soapResponse.generatedFault())
{
soapReturn = soapResponse.getReturnValue();
...process the response
}
else
{
Fault fault = soapResponse.getFault();
System.err.println("Generated fault: ");
System.out.println (" Fault Code = " + fault.getFaultCode());
System.out.println (" Fault String = " + fault.getFaultString());
}
