Using Xfire to develop WebService on eclipse

Finally, using Java to complete a webservice example, one of the very small problems that has plagued me for nearly a day. The steps below show how to develop WebService on the Java platform.

Tools used: Eclipse3.1.2 + Tomcat5.5 + XFire1.1. Using Xfire development WebService should be said to be very easy, just follow the steps in the following example:

(1) Create a new dynamic Web Project in Eclipse, assuming the name Xfirezhuweitest.

(2) Import the Xfire user library. The library should contain Xfire-all-1.1.jar files in the xfire-1.1 directory, and all files in the Xfire-1.1\lib directory.

(3) Copy all the files in the Xfire user library to the Webcontent\web-inf\lib directory of the Xfirezhuweitest project.

(4) Modify the contents of the Webcontent\web-inf\web.xml configuration file, the following is modified Web.xml:

<?xml version= "1.0" encoding= "UTF-8"
<web-app id= "webapp_id" version= "2.4" xmlns= "http://" Java.sun.com/xml/ns/j2ee "xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance "xsi:schemalocation=" http:// JAVA.SUN.COM/XML/NS/J2EE http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd "
<display-name>
XFire Zhuweitest</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome -file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</w Elcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>defaul T.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-li St>

<servlet>
<servlet-name>xfireservlet</servlet-name>
; servlet-class>
Org.codEhaus.xfire.transport.http.XFireConfigurableServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>xfireservlet</servlet-name>
<url -pattern>/servlet/xfireservlet/*</url-pattern>
</servlet-mapping>

<servlet-mapp Ing>
<servlet-name>xfireservlet</servlet-name>
<url-pattern>/services/*& Lt;/url-pattern>
</servlet-mapping>

</web-app>

The servlet mappings added in web.xml indicate that all matches "/services/*" URL request all to Org.codehaus.xfire.transport.http.XFireConfigurableServlet to deal with.

(5) Write Java classes that need to be published as WebService, a very simple mathservice.java in this example.

package　com.zhuweisky.xfireDemo;
public　class　MathService
{
　　　　 public　int　Add(int　a　,int　b)
　　　　 {
　　　　　　　　 return　a+b　;
　　　　 }
}

(6) Create a new Xfire folder in the Webcontent\meta-inf directory, and then add a Xfire profile services.xml in the Xfire directory that reflects which Java classes to publish as Web services. The services.xml in this example reads as follows:

<?xml　version="1.0"　encoding="UTF-8"?>
<beans　xmlns="http://xfire.codehaus.org/config/1.0">
　　　　 <service>
　　　　　　 <name>MathService</name>
　　　　　　 <namespace>http://com.zhuweisky.xfireDemo/MathService</namespace>
　　　　　　 <serviceClass>com.zhuweisky.xfireDemo.MathService</serviceClass>
　　　　 </service>
</beans>
