MOSS 2007 Web Services

MOSS 2007 web services are actually ASP.NET Web Services (ASMX). The physical files for these ASMX web services are located in the IIS virtual directory "_vti_bin" which physically maps to the folder "%Program Files%\Common Files\Microsoft Shared\web server extensions\12\ISAPI" through SharePoint metadata and HttpModules. Following are a few out of the box services available with MOSS 2007:

Search - spsearch.asmx
Lists - Lists.asmx
List Data Retrieval  - DspSts.asmx
People - People.asmx
Permissions - Permissions.asmx













spsearch service and methods


The admin web service for "Central Administration" is located in IIS virtual directory "_vti_adm" which physically maps to the folder  "%Program Files%\Common Files\Microsoft Shared\web server extensions\12\ADMISAPI."

Each one of these services consist of a *.wsdl.aspx file and a *.disco file too besides .asmx files for the service WSDL (Web Services Description Language), and  the service discovery implementation.

The URL for the Admin.asmx web service:
http://:portnumber/_vti_adm/Admin.asmx

The URL for all other services is:
http:///_vti_bin/.asmx

Differences between interface and abstract class

The interfaces and abstract classes, both can't be instantiated. While an abstract class contains both implemented and non-implemented methods, an interface contains only abstract methods.

INTERFACE

• An interface is pure contract
• Interface must be public
• It may be left unused after declaration
• When used, Implementing class must override all methods provided by that interface.
• It contains only unimplemented methods and no function definitions
• Variable must be abstract and final
• Methods take abstract as default.
• A single class can implement multiple interfaces.
• Interface properties are included with "implements" key word

ABSTRACT CLASS

• Abstract class must contain at least one abstract method
• It can contain function body
• It contains both implented and unimplemented method.
• It allows both abstract and non abstract methods.
•  It must be used if declared, otherwise compiler gives an error.
• It may be public or protected.
• Only one class can extend abstract class.
• Abstract properties are included with extends keyword.
