Information about WSDL, SOAP and WMLScript

[Jesus2]

Our group is making a project on Web services. We have to include three Web Services and we have decided to include WSDL(Web Services Description Language), SOAP and WMLScript. I need to collect information on these three topics. Please provide some information on them along with syntax and examples for the same.

[Katty]

To make it possible for the applications to carryout transaction using the HTTP we use the XML based protocol- SOAP. Thus Web services can be accessed by use of SOAP. The required skill to perceive SOAP are grasping the meaning of XML and XML Namespaces.

[Modifier]

The full form of SOAP is Simple Object Access Protocol. It is designed with the help of XML. It has the capability to access the internet as well. Thus SOAP is considered as communication protocol. So the communication between two application can be carried out by Simple Object Access Protocol

[Reegan]

To design application for Web services and to specify how to access them, the XML-based language 'Web Services Description Language- WDSL' is used. It is designed to describe Web services. The Web Services Description Language is coded using the XML language and therefore is an XML document.

[Praetor]

The web pages which are displayed in the web browser can be created using WML language. The acronym WML is for Wireless Markup Language. It is similar to the Hyper text Markup Language and is considered to be derived from it but it is infact an XML based language. WMLScript is similar to JavaScript language and WML uses this WMLScript to execute code on the client machine.a

[MindSpace]

Following are the syntax for Simple Object Access Protocol.

• The SOAP message should make use of the SOAP Encoding namespace.
• The SOAP message must not include any instruction for XML Processing.
• The encoding for SOAP message is to be done with XML.
• There should not be any reference to DTD.
