Getting below exception while authenticating oauth url in quick book.It's a probably a Jdk issue my version of JDK 1.6.19 release. I m read some java forum or doc find a solution. Problem in some JDK realese (1.6.17 ,18 , 19). When i am upgrade to 20+ release everything goes well.

After spending few hour to know reason but not find any relevant solution below is my EmployeModule Entity:-

package com.javastoreroom.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

/**
 * @author Arun
 * 
 */
@Entity
@Table(name = "module")
public class EmployeModule
{
  private Integer eId;
  private boolean status;
  private String docUrl;


//Generate getter setter property 

 }

Change to this :-

package com.javastoreroom.entity;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;

/**
 * @author Arun
 * 
 */
@Entity
@Table(name = "module")
public class EmployeModule
{
  private Integer eId;
  private Boolean status;
  private String docUrl;


//Generate getter setter property 

 }

Reading first line of exception find solution it says i am assign a null value to primitive data type. Here is boolean primitive type and i am assign a null to status. When i change boolean to Boolean wrapper class it working fine. :)

Toggle image in jquery , jquery - toggle arrow

If you want to toggle between 2 images either on click show or hide content arrow up or down below is a sample to do this :-

JavaScript

Css

.trigger {
background: url(http://etc-mysitemyway.s3.amazonaws.com/icons/legacy-previews/icons-256/3d-transparent-glass-icons-arrows/006768-3d-transparent-glass-icon-arrows-arrows-up-down1.png) 0px -20px no-repeat;
    cursor: pointer;
    height: 95px;
    left: -77px;
    position: absolute;
    top: 36px;
    width: 15%;
}

Add Above css and js in imagetoggle.jsp

imagetoggle.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
 pageEncoding="UTF-8"%>







Is it possible to make an down arrow image (class of .trigger) change to an image of an
up-arrow when clicked? Basically, I'm using an image with the class of
.trigger to toggle the div of .links, and when .links is revealed
(slided down), I want the arrow to face up instead of down to show that
users can click it again to hide .links again. Once the user hides links
by clicking the UP arrow, I want it to change to the down arrow again.
It's a lot of explaining for a simple task, but hopefully you guys
understand what I'm asking. The toggle code:

while running above jsp you get below output :-

click on above image you get final output and image toggle effect :-

Struts2- Gson Response Example

Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object.Download Google Gson Jar either add maven dependency:-

pom.xml

 com.google.code.gson
 gson
 2.2.4

Two Main method we use for conversion :-

1. toJson(Object src) 
   //This method serializes the specified object into its equivalent Json representation.
2. fromJson(JsonElement json, Class XXXX)
   //This method deserializes the Json read from the specified parse tree into an object of the specified type.

Gson Goals or benefit:-

1:- Provide simple toJson() and fromJson() methods to convert Java objects to JSON and vice-versa
2:- Allow pre-existing unmodifiable objects to be converted to and from JSON
3:- Extensive support of Java Generics
4:- Allow custom representations for objects
5:- Support arbitrarily complex objects (with deep inheritance hierarchies and extensive use of generic types)

Here is Sample Code how to work :-
