Package:

org.dinesh.softarica.productService.resources

Java File in above Package:

ProductResource.java

package org.dinesh.softarica.productService.resources;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("/products")
public class ProductResource {

@GET
@Produces(MediaType.TEXT_PLAIN)
public String getProducts() {
	return "Welcome Products";
}

}

Note: There are three annotations used in project named “Welcome Products:
@Path(“/products")
@GET
@Produces(MediaType.TEXT_PLAIN)

How it works:

Before you analyze, look at web.xml file.

<web-app..>

<servlet>
    <servlet-name>Jersey Web Application</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>org.dinesh.softarica.productService</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Jersey Web Application</servlet-name>
    <url-pattern>/webapi/*</url-pattern>
</servlet-mapping>

1. First of all tag is used inside . In we have two tags: and

2. The package inside is scanned and find the class called productService which contains one method - getProducts.

3. Finally getProducts method return the String “Welcome Products”.

To see the output, the url will be:

http://localhost:8080/productService/webapi/products
