New client class

Of course, you can also create a new web project to write client code. This time, the client service can be placed under the same project

In the bin folder of the JDK, there is a wsimport Exe, this tool generates corresponding class files according to WSDL files. With these class files, you can call the methods provided by WebService like calling local classes. The tool can be used for non Java servers, such as web services written in c# and generating java client implementations through wsimport.
