Difference between autowire byName and byType in Spring

Spring framework provides the way to inject the bean dependencies using the autowire functionality. By default autowire functionality is disabled in spring framework. A developer explicitly define the autowiring configuration in spring configuration xml file. And this point is to remember that autowiring is only supported for object dependencies.
The difference between byType and byName autowiring is as follows :

1. Autowire byType will search for a bean in configuration file, whose id match with the property type to be wired whereas autowire byName will search for a bean whose id is matching with the property name to be wired.
2. As a syntax wise difference is as follows:
   package com.evon;
   

   public class Company {    private Employee emp;    public String setEmp(Employee emp) {     this .emp = emp;     }          }

Java connectivity JDBC driver

Hi Friends,
This article will help you to identify basic connectivity using JDBC driver in Java. There are only four categories of JDBC driver provided by SUN, Type 1, 2, 3, and 4, which is explained below −



Type 1: JDBC-ODBC (Bridge Driver)
In a Type 1 driver, a JDBC bridge is used to access ODBC drivers installed on each system. One can configure ODBC on his system in a DSN ( Data Source Name) which will represent target of that database.
It was mostly used driver as it configures database in Access. But nowadays it is used only for test purpose besides that other DBMS drivers are being used.



Type 2: JDBC-Native API Driver
In a Type 2 driver, JDBC API calls are converted into native C/C++ API calls, which are unique to the database. These drivers are basically provided by the database vendors only and used in the same manner as the JDBC-ODBC Bridge. So vendor specific driver needs to be used on user system.

Registering Service using value in angularJS

A service is created by a service factory and service factories are functions which are created by a service provider(constructor function).

When instantiating service provider, there must be a property named $get, which holds service factory logic.
The $provide provide helping method for registering services with the help of $injector.

When we talk about registering a service using value, here value is nothing more than a simple injectable value. The value can be a string, number, array, function, object. The difference between value and constant is, it can not be injected into configuration. It accepts two parameters, that are: name and value. Syntax is:

value(name, value);

JSP Life Cycle

JSP is a server side scripting language. JSP is used to develop web applications. We can do everything on JSP which we can do with Servlet. In JSP we can add the Java code inside the HTML tags.


There are three service methods provided by JSP:

1. public void jspInit()
2. public void _jspService(HttpServletRequest request, HttpServletResponse response)
3. public void jspDestroy()
   

Following is the Life-cycle of JSP :

1. Parsing JSP : JSP page is first compiled for the syntax or other errors.
2. Translation from JSP to Servlet : After successfully parsing, the JSP is translated to the Servlet or Java file.
3. Compiling the Servlet : In this phase converted Servlet is compiled to class file.
4. Class Loading : Loading the Servlet class into memory.
5. Installation : Creating Servlet instance in memory.

Validations in Angular JS

Hello all,
We usually validate our HTML form before submitting it as it's a good practice to do that and to validate the HTML form we can use JavaScript Validation in client side, or we can also use custom JQuery code where we can apply different type logics and Regex to validate the form.
As an example we have following code packet which demonstrate the Validation feature of AngularJS :

<body ng-app="myApp">    <div class="container signInMainDiv">        <div class="table-responsive form-group">            <div ng-controller="AddUserController">                <form name="htmlForm" id="htmlForm" role="form" style="border:none; box-shadow:none;" ng-submit="htmlForm.$valid && addFormDetails(formDetails)">
