Hosting a web service is of no use until it becomes usable by a client. In this example we shall learn how to write JAX-WS client for a SOAP web service.<\/p>\n

Writing JAX-WS Client is easy. But we shall start our example by first creating a web service and then writing a client for the same.<\/p>\n

1. Writing server for web service<\/h2>\n

1.1 Writing Service Endpoint Interface<\/h3>\n

First step in writing web service server is to write the interface called Service Endpoint Interface that describes the methods that shall be exposed by web service.<\/p>\n

CalculatorI.java<\/em><\/span><\/p>\n

\r\npackage com.javacodegeeks.examples.jaxws;\r\n\r\nimport javax.jws.WebMethod;\r\nimport javax.jws.WebService;\r\nimport javax.jws.soap.SOAPBinding;\r\nimport javax.jws.soap.SOAPBinding.Style;\r\n\r\n@WebService\r\n@SOAPBinding(style = Style.RPC)\r\npublic interface CalculatorI {\r\n\t@WebMethod\r\n\tint add(int a, int b);\r\n\r\n\t@WebMethod\r\n\tint subtract(int a, int b);\r\n\r\n\t@WebMethod\r\n\tint multiply(int a, int b);\r\n\r\n\t@WebMethod\r\n\tint divide(int a, int b);\r\n}\r\n<\/pre>\n
1.2 Writing Service Implementation Bean<\/h3>\n
Next step is to write Service Implementation Bean. This is the implementation of Service Endpoint Interface.<\/p>\n
CalculatorImpl.java<\/em><\/span><\/p>\n
\r\npackage com.javacodegeeks.examples.jaxws;\r\n\r\nimport javax.jws.WebService;\r\n\r\n@WebService(endpointInterface = \"com.javacodegeeks.examples.jaxws.CalculatorI\")\r\npublic class CalculatorImpl implements CalculatorI {\r\n\r\n\t@Override\r\n\tpublic int add(int a, int b) {\r\n\t\treturn a + b;\r\n\t}\r\n\r\n\t@Override\r\n\tpublic int subtract(int a, int b) {\r\n\t\treturn a - b;\r\n\t}\r\n\r\n\t@Override\r\n\tpublic int multiply(int a, int b) {\r\n\t\treturn a * b;\r\n\t}\r\n\r\n\t@Override\r\n\tpublic int divide(int a, int b) {\r\n\t\treturn a \/ b;\r\n\t}\r\n\r\n}\r\n<\/pre>\n
1.3 Publishing the web service<\/h3>\n
And now comes the time to publish the web service. Here, we shall be using JAX-WS’s Endpoint<\/code> API to publish the web service or in other words publish the endpoint.<\/p>\n
CalcPublisher.java<\/em><\/span><\/p>\n
\r\npackage com.javacodegeeks.examples.jaxws;\r\n\r\nimport javax.xml.ws.Endpoint;\r\n\r\npublic class CalcPublisher {\r\n\r\n\tpublic static void main(String[] args) {\r\n\t\tEndpoint ep = Endpoint.create(new CalculatorImpl());\r\n\t\tep.publish(\"http:\/\/127.0.0.1:10000\/calcServer\");\r\n\t}\r\n\r\n}\r\n<\/pre>\n
In the above program, we are trying to publish the endpoint at URL: http:\/\/127.0.0.1:10000\/calcServer<\/code>.<\/p>\n
<\/a>1.4 Verify the web service<\/h3>\n
To verify if the web service has been properly published, we shall try to access the WSDL file from the browser. The URL shall be like: http:\/\/127.0.0.1:10000\/calcServer?wsdl<\/code>.<\/p>\n
Upon hitting this URL we will be able to see the WSDL file which describes the web service.<\/p>\n
Let’s copy the content of this file into calculator.wsdl<\/code>.<\/p>\n
calculator.wsdl<\/em><\/span><\/p>\n

2. Writing JAX-WS Client<\/h2>\n
2.1 Generating client code from WSDL<\/h2>\n
The first step to writing JAX-WS Client is to generate client support code. Java provides wsimport<\/code> utility that helps in generating this client support code using the WSDL document.
 
<\/div> <\/div><\/p>\n
On command prompt, enter following command at it will show the usage of this utility:<\/p>\n
$wsimport<\/code><\/p>\n
Now, let’s take the WSDL file that was saved in step 1.4<\/a>, browse to the saved directory using command prompt, and execute the following command:<\/p>\n
$ wsimport -keep -p client calculator.wsdl<\/code><\/p>\n
Alternatively, we can also specify the URL of WSDL file in the wsimport command:<\/p>\n
$ wsimport -keep -p client http:\/\/127.0.0.1:10000\/calcServer?wsdl<\/code><\/p>\n
Output of this command shall be like:<\/p>\n
\r\nparsing WSDL...\r\n\r\n\r\n\r\nGenerating code...\r\n\r\n\r\nCompiling code...\r\n<\/pre>\n
For the above example, it shall generate 2 java source files and 2 compiled files in the subdirectory client.<\/p>\n
\"Generated<\/a>
Generated Client Code<\/figcaption><\/figure><\/p>\n
Now, let’s breakdown the command that we used to generate client support code. Option -p<\/code> specifies the java package in which generated files are to be placed, in this case it was client. -keep<\/code> option is a flag that represents that generated files are to be kept. There are many other options which can be looked into by just writing wsimport<\/code> in the command prompt as mentioned above.<\/p>\n
2.2 Analyzing the client support code<\/h3>\n
Now let’s see the source files that wsimport<\/code> has generated for us. After that we shall analyze these.<\/p>\n

Points to be noted here:<\/p>\n
    \n
  1. wsimport<\/code> generated CalculatorI<\/code> contains the same methods as the original CalculatorI<\/code> at server side had.<\/li>\n
  2. CalculatorImplService<\/code> has a no-argument constructor that shall construct the Service<\/code> object.<\/li>\n
  3. CalculatorImplService<\/code> has a method getCalculatorImplPort()<\/code> that returns instance of CalculatorI<\/code> on which service methods shall be invoked.<\/li>\n<\/ol>\n
    2.3 Invoking the web service<\/h3>\n
    The last step to this tutorial is invoking the web service. To do this let’s first create a new java project and then copy the client support code into it.<\/p>\n
    You might want to change line#32 in CalculatorImplService<\/code> that mentions the URL to the HTTP URL instead of file path if you need it. In this case the updated CalculatorImplService<\/code> shall be like:<\/p>\n
    CalculatorImplService.java<\/em><\/span><\/p>\n
