Use of WSS web service for List/Library content updates

Problem:
WSS 3.0 (Windows SharePoint Services) and MOSS 2007
(Microsoft Office SharePoint Server)supports interoperability and remote operations through a set of web services.
There are number of approaches for programmatic access to SharePoint, such as the object model, web services, RPC over HTTP, as well as WebDAV.
All of these have their pros and cons depending on the needs of the application. The SharePoint RPC protocols can be useful and powerful and it certainly has its strengths,
especially when it comes to adding content. The object model is much more robust and feature rich than the web services, but it does not offer support for remote operations,
so in order to leverage the object model your code must be running on the SharePoint server, and you must be writing .NET code in order to leverage it. There are a number of different
reasons for working with SharePoint data remotely, be it administrative scripts or the need to work with SharePoint content such as tasks in an application running on a client machine,
or non-SharePoint applications in the enterprise. The SharePoint web services are built on top of the object model and expose a subset of features available in the object model, and
allow for remote operations and the use of any language and platform that supports the consumption of web services. For most tasks the web services that ship in SharePoint are
adequate, but you may find needed operations in the object model that have not been surfaced in the web services, which will require extending the web services with a custom web
service implementation. In this article we will take a look at available web services and an example on how to use it.

Solution:

If your site is up and running, you would see that it opens a page withing the frame and at the right it says.. “1 Service Found”. Give a Web Reference Name and Click on “Add Referece”.
