Ans.) No Need to write any object model code............................
Just use existing webservices in sharepoint.
Create a new web services application.
Add web references for the Sharepoint site which you want to write you custom services.
Ex:http://[SERVER:Port]/_vti_bin/usergroup.asmx
http://[SERVER:Port]/_vti_bin/lists.asmx
MOSS 2007 web services

If you want do list related custom code, use "Lists.asmx"...........
Here i am going to write a custom code to upload a attachment in the list.
[WebMethod]
public void Upload(string ListName,byte[] bytestream,string ListItemID, string FileName)
{
try
{
Lists.Lists ListsWebService = new Lists.Lists();
ListsWebService.Credentials = new NetworkCredential("USERID", "PASSWORD", "DOMAIN");
ListsWebService.AddAttachment(ListName, ListItemID, FileName, bytestream);
}
catch (Exception ex)
{
throw ex;
}
}
