J2ee Architecture

J2ee is a java core architecture.It is a famous technology for the enterprise application.Consider about j2ee there are lot of technology.
  • Jsp
  • ejb
  • Servlet
  • Jms
These are the main technologies in J2ee.These are introduced by Sun micro system.There are lot of design patterns in j2ee.I,m familiar with MVC design pattern.Lot of application developed using MVC architecture.M-model, V-view, C-control .




jsp
jsp is the main client side component in j2ee. There are two way to design jsp pages

  • Scriplets
  • Tag libraries
Scriplets
Scriplet mean we can write java code in HTML page using <% %>,<%= %> tags. Using this pattern we can design very easily.But not efficient. Because if we are using scriplet code in jsp page.This code execute on the client side that is the reason.
Tag libraries
Tag Libraries mean we can write jsp page using tags.There are standard tag libraries in j2ee and we can define our own tag libraries.It is efficient war to developing jsp pages

How to enable proxy service security in ESB 4.9.0?

These specifications define a behavior model for web services. Proxy service security requirements are different from each others. WSO2 ESB providing pre-define commonly used twenty security scenarios to choose based on the security requirements. This functionality is provided by the security management feature which is bundled by default in service management feature in ESB. This configuration can be done via the web console until ESB 4.8.1 release, but this has been removed from the ESB 4.9.0. Even though this feature isn't provided by the ESB web console itself same functionality can be achieved by the new WSO2 Dev Studio. WSO2 always motivate to use dev studio to prepare required artifacts to the ESB rather than the web console. Better way to explain this scenario is by example. Following example …

How SSL Tunneling working in the WSO2 ESB

This blog post assumes that the user who reads has some basic understanding of SSL tunneling and the basic message flow of the ESB.

It is maintaining status (REQUEST_READY, RESPONSE_READY .. ,etc) based on the events which fired by the IOReactor and executing relevant methods. As the example if a response which is coming from the backend side hits to the ESB, IOReactor fire the responseRecived method in the targetHandler side. Followings are the basic methods contain in the target handler and their responsibilities.
