Web Service Development Based on JAX-WS on myeclipse6.5

JAX-WS (Java API for XML-Web Services)

Environment Description:
Myeclpose 6.5 blue milestone-1
JDK 1.6.0 _ 15
Tomcat 6.0

Create and publish server applications

1. Create a Web Service Project.
Set as shown in.


2. Create an implementation class with the following code:

 

Package Net;

Public ClassAddimpl {
Public DoubleAdd (DoubleNum1,DoubleNum2 ){
ReturnNum1+Num2;
}
}

 

Here, you only need to implement the class, and do not need an interface like xfire.

PS: Web services can be implemented by a single Java class, but it is best to use the "interface + Implementation" method.
3. Create a webService
Select a project name and click the new Web Service button in the toolbar.

Then configure as follows:

Next (enter the name of the implementation class in Java Bean and select generate WSDL in project ):

After you click Finish, the package contains an additional proxy class addimpldelegate. Java for this implementation class.

4. Import package
Project-properties-build path-add library-myeclipse libraries import the following two packages:

If the two packages are missing, the following error occurs during Tomcat startup:

 

Severe: Error Handling application listener Class Com. Sun. xml. ws. Transport. http. servlet. wsservletcontextlistener
Java. Lang. classnotfoundexception: COM. Sun. xml. ws. Transport. http. servlet. wsservletcontextlistener

 

5. Start tomcat, verify and obtain the WSDL File

After Tomcat is started, enter http: // localhost: 8080/jaxws_src/addimplport in the browser and click the link on the page to view the WSDL file. If the file is correctly displayed, the server is declared successful.
The URI of the WSDL file isHttp: // localhost: 8080/jaxws_src/addimplport? WSDL (You may ask where the addimplport in Uri comes from. In fact, this name is set by the Service port in Figure 4)

 

PS: The following classes are available in Web. xml. You can see the role of this/addimplport.

Code

  < Servlet >
< Description > The JAX-WS endpoint-addimplservice </ Description >
< Display-name > Addimplservice </ Display-name >
< Servlet-name > Addimplservice </ Servlet-name >
< Servlet-class >
Com. Sun. xml. ws. Transport. http. servlet. wsservlet
</ Servlet-class >
< Load-on-startup > 1 </ Load-on-startup >
</ Servlet >
< Servlet-Mapping >
< Servlet-name > Addimplservice </ Servlet-name >
< URL-Pattern > /Addimplport </ URL-Pattern >
</ Servlet-Mapping >

 

 

Create a client call:

(Do not close tomcat, otherwise .....)
1. Create a Java project and create a package (package name Security Requirements). Net.
2. Select the package point new Web Services Client (refer to the second figure in this article)
PS: Do not use xfire. The client is not necessarily a web services client of the same type as the server. It can be a common project and OK !!
3. Specify the file path of the URI or WSDL of the WSDL (see above ).
The program generates some classes in the net package.

PS: The Add. Java in the figure is a JavaBean. You should know how it works !!
4. Create a new test class:

 

Package Com;

ImportNet. addimpldelegate;
ImportNet. addimplservice;

Public   Class Test {
Public   Static   Void Main (string [] ARGs ){
Addimplservice Service = New Addimplservice ();
Addimpldelegate d = Service. getaddimplport ();
Double Result = D. Add ( 15.6 , 12.5 );
System. Out. println (result );
}
}

 

OK! You are done !!
