Java calls third-party WebService application instances

There are many free webservice services on the Internet, and we can call these free webservice services to integrate content information from some other sites into our web apps.

Links to some of the commonly used WebService websites: HTTP://WWW.TUICOOL.COM/ARTICLES/IIFQMA

One: Call free Web service to get weather forecast information

1. Third party service address

Http://www.webxml.com.cn/WebServices/WeatherWebService.asmx

http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl

2. Generate local piles (automatically generate client code with the Wsimport command tool)

Open a command line window, switch to the project's SRC directory, execute "wsimport-keep http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx?wsdl" to generate the client code, As shown in the following:

Running results show that using the Wsimport tool to generate the client code directly throws an exception, unable to generate the client code, Just because the webservice we're going to call is written in. NET, this is the problem with the Java call Net WebService, the solution to this problem is as follows:

1. Save the corresponding WSDL document to a local

　　

2. Modify part of the WSDL document: replace <s:element ref= "S:schema"/><s:any/> with <s:any minoccurs= "2" maxoccurs= "2"/>

　　

Execute the Wsimport generated code again, this time using a local weatherws.wsdl file to generate it, as shown in:

　　

From the execution results show, this time can generate code normally, refresh the SRC directory, you can see the generated code, as shown in:

　　

3. Write the request code with the generated code
