Checked & Unchecked Exceptions

|

Checked Exceptions
  • are subclasses of java.lang.Exception
  • need to be declared in a method or constructor's throws clause
Unchecked Exceptions
  • are subclasses of java.lang.RuntimeException
  • do not need to be declared in a method or constructor's throws clause

In the context of common transaction APIs, such as JTA or Spring transaction APIs;
any RuntimeException triggers rollback, and any checked Exception does not rollback the transaction.

Dependency Injection In Java and CDI

|
Dependency injection(DI) is one of the key techniques that enables a class or module to be injected into another, which also enables us to apply the principal of seperation of concerns via enabling a way of entity association and making wiring easy.

Along with Java EE 5, dependency injection was made of a part of the specification with JSR 250 (Common Annotations). For basic usages of injection, it has been a good start for Java platform especially with the annotations; @ManagedBean and @Resource.

Since Java EE 6, JSR 330 (Dependency Injection for Java) was introduced and the frequently used annotations like @Inject and @Named were made available. And ultimately, Contexts and Dependency Injection was also introduced with Java EE 6 which is built on top of JSR 330. Comparing to DI, CDI additionally provides an easy to use event mechanism, decorators and interceptors to add functionality to beans.

Since Java EE 5 with the EJB 3.0 specification, Java EE also provides injection for EJBs whic…

Servlet

In Java EE world, Servlet simply is a web technology with which we can receive and handle the HTTP requests, create HTTP response and return that response back to the client.

Servlet technology makes a basis for other Java web technologies on top of which other frameworks put their extensions. For example JSP, JSF, Spring MVC are such technologies which are uses Servlet technology at behind. 

Servlets run on a web container such as Tomcat which provides the services on Java EE technology stack. 
What is a servlet ?Servlet simply makes an object having HTTP-server functionality when its class extends HttpServlet class.
A servlet is mapped to a URL to which clients requestHTTP requests made to the URL is directed to the corresponding Servlet objectServlet implementation receives the request in the form of GET, POST, PUT or DELETEServlet implementation runs a business logic and prepares an HTTP response and sends it back to the client just an HTTP server doesLifecycle of the servlet is manag…

Spring Components & Auto Scanning & Configuration

|
Spring managed beans are declared with the stereotype annotations specialized from @Component or with the @Component annotation itself.
When you declare a class with @Component[+derived] annotations, that bean is detected by Spring, via component scanning or explicitly wiring,
and put into the ApplicationContext.
1. Component ScanningIn a Spring application, you can declare your beans manually inside the bean configuration file,
but most probably, auto scanning of components is the preferred way of registering your beans into the application context.

You can configure auto scanning in bean configuration file or with the annotation.
1.1 Enable Auto-Scanning in Bean Configuration FileThis is available since Spring 2.5:
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframe…
