In
this example we are going to show generating XML response
Steps:
1. WEB.xml :
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<display-name>com.tushar.jersey.Project</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>jersey-serlvet</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>com.tushar.jersey.Project</param-value>
</init-param>
<init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>jersey-serlvet</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>

2. Create Service class
package
com.tushar.jersey.Project;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import
javax.ws.rs.PathParam;
import
javax.ws.rs.Produces;
public class XMLResponse {
@GET
@Produces("application/xml")
public String convertCtoF() {
Double fahrenheit;
Double celsius = 36.8;
fahrenheit = ((celsius * 9) / 5)
+ 32;
String result = "@Produces(\"application/xml\")
Output: \n\nC to F Converter Output: \n\n"
+ fahrenheit;
return "<ctofservice>" + "<celsius>" + celsius + "</celsius>"
+ "<ctofoutput>" + result + "</ctofoutput>" + "</ctofservice>";
}
@Path("{c}")
@GET
@Produces("application/xml")
public String convertCtoFfromInput(@PathParam("c") Double c) {
Double fahrenheit;
Double celsius = c;
fahrenheit = ((celsius * 9) / 5)
+ 32;
String result = "@Produces(\"application/xml\")
Output: \n\nC to F Converter Output: \n\n"
+ fahrenheit;
return "<ctofservice>" + "<celsius>" + celsius + "</celsius>"
+ "<ctofoutput>" + result + "</ctofoutput>" + "</ctofservice>";
}
}
|
3. Execute the Code
http://localhost:8080/com.tushar.jersey.Project/rest/xmlResponse
Output
