Java WebService Tutorial - Part 06 ( Using wsimport tool to generate Client and accessing a Webservice )

In this tutorial we will see how wsimport tool can be used to generate java classes from a wsdl and how we can access a webservice easily like normal java applications.

wsimport :

This tool is come along with the jdk.If you have install the JDK properly and your classpath or JAVA_HOME variable is set you can see the list of options provided by this command  by typing wsimport in the command prompt.

For generating Java classess from wsimport the syntax is :

wsimport  wsdl-location-path  -d -keep

The wsdl-location-path : Is the location of wsdl file existence.

-d : specify the directory where all the generated classes should be placed.

-keep : It will keep the java source code of generated classes in the respective directory mentioned.

-extension :allow vendor extension - functionality if not have been specified.

Ex:

wsimport  hello.wsdl   src  -keep

Now we will take the sample webservice of w3schools which has the follwing wsdl location:

http://www.w3schools.com/webservices/tempconvert.asmx?WSDL

Execute the command in DOS Prompt to generate classes from wsdl :

 C:\webservice> wsimport  http://www.w3schools.com/webservices/tempconvert.asmx?WSDL -extension   -keep
 

After execution it will create a folder called org inside the webs service folder.

Now Create a Main class to access these webservice :

 Code:

import org.tempuri.*;

 public class Main {
   
    public static void main(String a[])
    {
        TempConvert convert=new TempConvert();
        System.out.println(convert.getTempConvertSoap().celsiusToFahrenheit("122"));
       
    }
}
   
Save these class inside "webservice" folder .Compile and run it you will see the output as "251.6" returning from web service.

Result :
