Hi,
I am new to J2ME, just started
working on a project where my J2ME application needs
to receive/send data to .NET web service. I have written a sample
code to test the service. I was able to get the data from the server.
Now, my question here
is:
1. How do I parse and get the data
from the response I got from the server since it contains lot of
things?
2. I have this
XML
<Cust_Appointment><Record><Internal_Cust_Id>1</Internal_Cust_Id><Appointment_Type>1</Appointment_Type><Appointment_Date>5-June-2003</Appointment_Date><User_Id>1</User_Id><Description><![CDATA[Mobile
Demo]]></Description><Active_Date>5-June-2002</Active_Date><Inactive_Date>
5-June-2004</Inactive_Date></Record></Cust_Appointment>
How do I send it to the Server?? I
was able to connect to the server but it returned a Fault as
below:
Buffer:<?xml version="1.0"
encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<soap:Fault>
<faultcode>soap:Client</faultcode>
<faultstring>Server was unable to read request. --> The
&lt;Cust_Appointment&gt; tag from namespace is expected.
Line 1, position 2.</faultstring>
<detail />
</soap:Fault>
</soap:Body>
</soap:Envelope>
Here is the sample I am using
right now for reading/sending data from/to the
server:
