Thread: how to write jeresy web applications code using @POT, @PUT @DELETE

Hello every Body,

i am just new with jeresy web applications (restfull applications), so now i know how deal with @Get, but the problem how to make it with @put, @post, and @ delete
i will write a very simple example.

import java.util.ArrayList;
 
public class ArrList1 {
 
protected static ArrayList col1 = new ArrayList();
 
 
	public  void arrList() {
		col1.add("hallo");
		col1.add(2);
		col1.add(3);
		col1.add(4.0);
		col1.add(5.25);
		col1.add(6);
}
}

Now the Jeresy Code

import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;
 
@Path("/ArrayList2Jersy")
public class RestfullJersy extends ArrList1{
	@GET
	public Response arrList() {
 
		ArrList1 read = new ArrList1();
		read.arrList();
 
//print the value of the cells which is stored in the the Arraylist
	    System.out.println("");
	    for (int i = 0; i < col1.size(); i++){
	    Object item = col1.get(i);
	    	}
 
		        String result = " Output: \n\nArrayList Output: \n\n" + item ;
		        return Response.status(200).entity(result).build();
 
	}
}

web.xml

HTML Code:

  <servlet>
    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
            
	    <init-param>
		<param-name>com.sun.jersey.config.property.resourceConfigClass</param-name>
		<param-value>com.sun.jersey.api.core.PackagesResourceConfig</param-value>
	    </init-param>
        <init-param>
          <param-name>com.sun.jersey.config.property.packages</param-name>
          <param-value>pal.restfulservice</param-value>
        </init-param>
    
    <load-on-startup>1</load-on-startup>
  </servlet>
  
  <servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/jeresy/*</url-pattern>
  </servlet-mapping>
  
  <session-config>
    <session-timeout>30</session-timeout>
  </session-config>
</web-app>

http://localhost:8080/RestFul/jeresy/ArrayList2Jersy and i will get all element in the arraylist (where RestFul is the name of the Project)

now all what i want how to write code to add new element in the arraylist @POST or update it @PUT or remove it @DELETE

for example if i want to add new element col1.add(34); how to write it with @POST and what should the URL to call it?
