Tomcat web service release tutorial

I have been preparing for a job these days. I learned some basic content about Web Service and encountered many problems. Now I will share with you what I have learned. As I am a beginner, please correct me for any errors. Thank you ~~!!

1. Download the Jax-ws dependency package

Because Tomcat does not have the dependent environment required by Jax-WS, the first step is to download the Jax-ws Ri, that is, the Jax-ws reference implemantation, address: http://jax-ws.java.net.

2,Install JAX-WS Ri On the Tomcat server

First download ant and Tomcat and set Environment VariablesAnt_home and catalina_home, and then introduce their respective bin directories under pathOpen the command prompt and run ant install in the directory of the Jax-ws Ri package.

This command will directly import the required package to the $ {Tomcat} \ shared \ lib directory, in fact, the package under jaxws Ri Lib is copied to shared \ Lib under the tomcat installation directory.

3,Set tomcat in eclipse

Because eclipse is a custom tomcat configuration file, you need to add something to add shared \ Lib,Open the ctalina. properties file.

Find the common. loader configuration item and add$ {Catalina. Home}/shared/Lib/*. Jar, $ {Catalina. Home}/shared/lib These two paths are enough.

4. Create a project

Create a web project, webservice_web. The directory structure is as follows:

 

Helloservice. Java is an interface that provides Web Services,CodeAs follows:

Package com. zxuqian. WebService; import javax. JWS. webmethod; import javax. JWS. WebService; @ webservicepublic interface helloservice {@ webmethod string greetings (string name );}
 

Helloserviceimpl. Java is an implementation class and the code is as follows:

 
Package COM. zxuqian. webService. impl; import javax. JWS. webService; import COM. zxuqian. webService. helloservice; @ WebService (endpointinterface = "com. zxuqian. webService. helloservice ") public class helloserviceimpl implements helloservice {@ override Public String greetings (string name) {return" Hello: "+ name ;}}
 

5. Add sun-jaxws.xml

The sun-jaxws.xml is a Web-based Web Service Application description file, the content is as follows:

 

 
<? XML version = "1.0" encoding = "UTF-8"?> <Endpoints xmlns = "http://java.sun.com/xml/ns/jax-ws/ri/runtime" version = "2.0"> <endpoint name = "helloworld" implementation = "com. zxuqian. webService. impl. helloserviceimpl "url-pattern ="/Hello "/> </endpoints>
 

 

For more information about each node, see the docs document in the jaxws Ri package.
The interface and implementation class of the web service and its URL relative path

6. Configure web. xml

the content is as follows:

 
   
   
   
     webservice_web 
    
   
     COM. sun. XML. WS. transport. HTTP. servlet. wsservletcontextlistener 
     
   
     Hello 
    
   
     COM. sun. XML. WS. transport. HTTP. servlet. wsservlet 
    
   
     1 
     
    
    
      Hello 
      
     
      /Hello 
      
    
    
   

7. Test

Start Tomcat and enter the Web service address http: // localhost: 8088/webservice_web/hello in the browser. The Tomcat port number is 8088. Modify the port number accordingly.
