on the server should be able to catch all exceptions and should return only universal errors. For XML Web Services, you should return SOAP errors with little platform information. You may want to return the data to the user in some way, along with the ID, to compare the errors with the records in the audit log, but place the error details in the audit log instead of the returned SOAP error. It is recommend
felt every time you click the "Next" button in the Wizard, for example, a pause or a more serious program does not respond for a period of time. In fact, for web services, you can set the request XML in each step (this setting is performed locally). After all the steps are completed, then, XML is sent to the server for processing. In this way, operations between each step are performed locally, without any

As loosely coupled computing and XML WEB services continue to grow, organizations increasingly need tools to deliver successf
most basic solution to the implementation of the XML Web service is to provide some basic functional modules for the customer to use. For example, an E-commerce application is challenged by the need to calculate charges for different freight modes. Such applications need to obtain the current shipping cost form from each shipping company in these calculations.
Applications can use standard transport protocols such as HTTP to send a simple xml-based
users, a Web Service is an object/component deployed on the Web. It has the following features:
Sound encapsulation. Since Web services are deployed on the web, they naturally have good encapsulation of objects. for users, you can only view the function

In many previously developed Web API projects, the Controller of the entire Web API is usually placed in the Controllers directory of the base directory for convenience and rapid development. However, as the business becomes more and more complex,

Web services are really exciting parts of. NET-but they are bigger than. Net. The truth is simple. Almost every service you can name has a mechanism for executing server-side code: You enter a URL in the browser's address bar, receive your request, start running something on the server, and then return the results you want with the HTML page. It could be asp,asp.net,servlets, or even Perl, which was trigger

-independent mechanism. The communication of SOAP messages uses XML to describe objects, methods, and parameters for execution. Both the client and the server can implement and use SOAP. In this way, the Soapconnect for LotusScript package makes it easy to use its implementation, and developers can do without processing the underlying XML.
