RESTful Web Services with Java (JAX-RS) using DELETE Method


RESTful Web Services Using DELETE Method Using Jersey
 
If we are use DELETE method then need a client to run application . you have any client then ok.if you have not any idea about client then you first learn about client. There are many client postman,rest console etc. But I have use rest console client , for rest console client tutorial click here

So now i consider that you can use rest console client .

now follow these step for make a rest application using put method

Step 1: create handle class and define path , method and response.

UserHandler.java

package com.javaproficiency.jerseydemo.demo;


import javax.ws.rs.DELETE;
import javax.ws.rs.Path;
import javax.ws.rs.core.Response;
import javax.ws.rs.core.Response.Status;

@Path("/user")
public class UserHander {

    /*

     Use @DELETE annotation here

        */
  
    @DELETE
    public Response getMessage(){
        String message="Jersey Hello By Java Proficiency";
        return Response.status(Status.OK).entity(message).build();
    }
  
}


Step  2. configure web.xml file as

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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
  <display-name>JerseyDemo</display-name>
    <servlet>
        <servlet-name>RestServices</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

        <init-param>
            <param-name>jersey.config.server.provider.packages</param-name>
            <param-value>com.javaproficiency.jerseydemo.demo</param-value>
        </init-param>

        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>RestServices</servlet-name>
        <url-pattern>/rest/*</url-pattern>
    </servlet-mapping>
</web-app>

Step 3. Add dependency in pom.xml file as bellow.
pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    </dependencies>

</project>

Step 4:   Project Structure





 Step 5: Run Project and Hit url
