How to Start Jersey Api Framework

 1. How to Use 

Jersey Hibernate File

step 1: Open dilsecodie

step 2: Rest Api section goto jersey part 

step 3: copy hibernate code in hibernate.cfg.xml 

step 4: use for session factory connection from the database any database  like Mysql,SQL , oracle 

step 5: the table should be mapped in hibernate file as an entity class.

From Jersey Framework we can develop any restful API structure 

To start with Jersey project, add jersey dependencies to pom.xml file in any dynamic 

projects mainly jersey dependency depend on these dependencies you can add these in your project.  

<dependency>

    <groupId>com.sun.jersey</groupId>

    <artifactId>jersey-json</artifactId>

    <version>1.19.4</version>

</dependency>

 <dependency>

    <groupId>com.sun.jersey</groupId>

    <artifactId>jersey-atom</artifactId>

    <version>1.19.4</version>

</dependency>

<dependency>

    <groupId>com.sun.jersey</groupId>

    <artifactId>jersey-fastinfoset</artifactId>

    <version>1.19.4</version>

</dependency>

 <dependency>

    <groupId>com.sun.jersey.contribs</groupId>

    <artifactId>jersey-multipart</artifactId>

    <version>1.19.4</version>

</dependency>

Now can add some changes in web.xml file 

<servlet>

  <servlet-name>s1</servlet-name>

  <servlet-class>

 org.glassfish.jersey.servlet.ServletContainer</servlet-class>

  <init-param>

  

  <param-name>jersey.config.server.provider.packages</param-name>

  <param-value>resource</param-value>

  

  

  </init-param>

 <init-param>

    <param-name>jersey.config.server.provider.classnames</param-name>

    <param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>

</init-param>

  <load-on-startup>1</load-on-startup>

  </servlet>

  <servlet-mapping>

  <servlet-name>s1</servlet-name>

  <url-pattern>/rest/*</url-pattern>

  </servlet-mapping>

  <welcome-file-list>

<welcome-file>

index.jsp

</welcome-file>

  </welcome-file-list>

So when any request comes to action class it is 1st call servlet where the rest as URL,

then its search endpoint  for API where its map its end from scanning param value 

packages to get all URLs 

ServletContainer is a servlet class that loads all packages which have URLs endpoint.

These are the import packages required for the jersey action class

import javax.servlet.http.HttpServletRequest; - for request handler 

import javax.ws.rs.GET;

import javax.ws.rs.Path;

import javax.ws.rs.Produces;

import javax.ws.rs.core.Context;

import org.apache.wink.json4j.OrderedJSONObject;

import org.hibernate.Session; - to start hibernate session 

@Path("/demoList") - its for end point for API .
