How to connect to a .NET Web Service from a J2ME MIDlet using kSOAP 2

Web services had and continue to have a great impact on the development of Web applications because they allow total independence between clients and service providers. The location, the platform, the programming language and the architecture of both the clients and the services has no effect on each other. The Internet technologies and standards that allowed the implementation of Web services are HyperText Transfer Protocol (HTTP), eXtensible Markup Language (XML), Remote Procedure Call (RPC), Web Services Description Language (WSDL), Simple Object Access Protocol (SOAP) and Universal Description, Discovery, & Integration (UDDI).

In this article we will see how to connect to a .NET Web Service from a j2ME MIDlet using kSOAP2 library. The Java 2 Micro Edition (J2ME) Platform offers support for Web Services through the J2ME Web Services API (WSA), JSR 172, which provides two optional APIs: remote service invocation (JAX-RPC) and XML parsing (JAXP). For the next example, we will use the third party kSOAP 2 library because it is lightweight and efficient. The solution is developed in the NetBeans IDE but you could use also Eclipse IDE.
