[WS] Using axis to publish simple Web Services

Using axis, it is very simple to publish a web service. Although the process and relatedCodeLong. I used these software in this post: Axis 1.1, eclipse 2.1, and eclipse Tomcat plug-in 2.2 (sysdeo Tomcat plugin ). The release method is as follows:

The service I want to publish is a library store. The publishing methods include adding books addbook, listbooks, and deletebook. For the sake of simplicity, only one method for adding books is released, because the release of other methods is similar.

1. Create a tomcat project named bookstore in eclipse. Note that this option is available only when the Tomcat plug-in mentioned above is installed. If there is no installation, you can create a Java project, then manually create the necessary directory structure (WEB-INF, etc.), and manually add the <context> item corresponding to the project in Tomcat server. xml.

2. Create a library class (COM. Bookstore. model. Book). The book has three attributes: name, ISDN number, and page number. This is a bean class. The Code is as follows:

 Package  Com. Bookstore. model;  Public   Class  Book {  Private String name;  Private  String ISDN;  Private   Int  Page;  Public  String getisdn (){  Return  ISDN ;}  Public  String getname (){  Return  Name ;}  Public   Int Getpage (){  Return  Page ;}  Public   Void  Setisdn (string) {ISDN = String ;}  Public   Void  Setname (string) {name = String ;}  Public   Void Setpage ( Int I) {page = I ;}} 

3. Create a class (COM. bookstore. booksvc), this class is the actual function class, which has only one public addbook () method, and only one of its parameters is the book to be added. The Code is as follows:

 
PackageCom. Bookstore;ImportCom. Bookstore. model. Book;Public ClassBooksvc {Public VoidAddbook (Book ){//Here you save a book into databaseSystem. Out. println ("book has been added .");}}
 

4. Now, extract the downloaded axis to a folder, which is assumed to be removed to c: \ axis-1_1. Copy all. Jar files under the c: \ axis-1_1 \ webapps \ axis \ WEB-INF \ lib directory to your web applicationProgramUnder the WEB-INF \ Lib, then copy the Web. xml under the c: \ axis-1_1 \ webapps \ axis \ WEB-INF directory to the WEB-INF of your web application. This step is equivalent to configuring axis in your web application.

5. To let axis know which services you want to publish, you have to create a file named WEB-INF under the server-config.wsdd with the following content:

 <?  XML version = "1.0" encoding = "UTF-8"  ?>  <  Deployment  Xmlns  = "Http://xml.apache.org/axis/wsdd"  Xmlns: Java  = "Http://xml.apache.org/axis/wsdd/providers/java" >   <  Globalconfiguration  >    <  Parameter  Name  = "Adminpassword"  Value  = "Admin"  />    <  Parameter  Name  = "Attachments. directory"  Value = "C: \ eclipse \ workspace \ bookstore \ WEB-INF \ attachments"  />    <  Parameter  Name  = "Attachments. Implementation"  Value  = "Org. Apache. axis. attachments. attachmentsimpl"  />    <  Parameter  Name  = "Sendxsitypes"  Value  = "True" />    <  Parameter  Name  = "Sendmultirefs"  Value  = "True"  />    <  Parameter  Name  = "Sendxmldeclaration"  Value  = "True"  />    <  Parameter Name  = "Axis. sendminimizedelements"  Value  = "True"  />    <  Requestflow  >     <  Handler  Type  = "Java: org. Apache. axis. Handlers. mongoshandler"  >      <  Parameter  Name = "Scope"  Value  = "Session"  />     </  Handler  >     <  Handler  Type  = "Java: org. Apache. axis. Handlers. mongoshandler"  >      <  Parameter  Name  = "Scope" Value  = "Request"  />      <  Parameter  Name  = "Extension"  Value  = ". JWR"  />     </  Handler  >    </  Requestflow  >   </ Globalconfiguration  >   <  Handler  Name  = "Localresponder"  Type  = "Java: org. Apache. axis. Transport. Local. localresponder"  />   <  Handler  Name  = "Authenticate"  Type  = "Java: org. Apache. axis. Handlers. simpleauthenticationhandler" />   <  Handler  Name  = "Urlmapper"  Type  = "Java: org. Apache. axis. Handlers. http. urlmapper"  />   <  Service  Name  = "Version"  Provider  = "Java: RPC"  >    < Parameter  Name  = "Allowedmethods"  Value  = "Getversion"  />    <  Parameter  Name  = "Classname"  Value  = "Org. Apache. axis. Version"  />   </  Service  >  <  Service  Name  = "Booksvc"  Provider  = "Java: RPC"  >    <  Parameter  Name  = "Allowedmethods"  Value  = "*"  />    <  Parameter  Name = "Classname"  Value  = "Com. Bookstore. booksvc"  />   </  Service  >   <  Service  Name  = "Adminservice"  Provider  = "Java: MSG"  >    <  Parameter Name  = "Allowedmethods"  Value  = "Adminservice"  />    <  Parameter  Name  = "Enableremoteadmin"  Value  = "False"  />    <  Parameter  Name  = "Classname" Value  = "Org. Apache. axis. utils. admin"  />    <  Namespace  > Http://xml.apache.org/axis/wsdd/ </  Namespace  >   </  Service  >   <  Transport  Name  = "Local" >    <  Responseflow  >     <  Handler  Type  = "Localresponder"  />    </  Responseflow  >   </  Transport  >   <  Transport Name  = "HTTP"  >    <  Requestflow  >     <  Handler  Type  = "Urlmapper"  />     <  Handler  Type  = "Java: org. Apache. axis. Handlers. http. httpauthhandler"  />   </  Requestflow  >   </  Transport  >  </  Deployment  > 

This file contains three services: version, adminservice, and booksvc. There is another way to generate this file, as if axis recommends using this generation method, it is to write a deploy in the same directory. WSDD file (skip to the next step if you do not want to view it). The content is as follows:

 <  Deployment  Xmlns  = "Http://xml.apache.org/axis/wsdd"  Xmlns: Java = "Http://xml.apache.org/axis/wsdd/providers/java"  >   <  Service  Name  = "Booksvc"  Provider  = "Java: RPC"  >    <  Parameter  Name  = "Classname"  Value  = "Com. Bookstore. booksvc"  />   <  Parameter  Name  = "Allowedmethods"  Value  = "*"  />   </  Service  >  </  Deployment  > 

That is to say, deploy. WSDD contains only the description of our service, confirm that tomcat has been started, and then generate the server-config.wsdd file with the following command in the same directory:

Java org. Apache. axis. Client. adminclient-lhttp://Localhost: 8080/bookstore/services/adminservice deploy. WSDD
 

Bookstore is the virtual path of my web application.

6. Restart Tomcat and access the path http: // localhost: 8080/bookstore/services. You can see that three Web services are released, for example. Click the WSDL link after each service to view the corresponding WSDL description.
