Eclipse validating cancel requested
Welcome to the Part 2 of 7-part series where we will explore the world of Struts 2 Framework.
In previous article we went through the basics of Struts2, its Architecture diagram, the request processing lifecycle and a brief comparison of Struts1 and Struts2.
I assume you have already configured Tomcat in eclipse. A good application always show proper error messages to user.
All you need to do: Open Server view from Windows - Run on Server (Shortcut: Alt Shift X, R) But there is one small problem. But when user enters wrong credential, she is redirected to Login page. So we must display an error message when user authentication is failed.
Login page Welcome page Login page with error Source Code without JAR files (9 KB) Source Code with JAR files (3 MB) Now that we have created our first webapp using Struts2 framework, we know how the request flows in Struts2. In this application we implemented a preliminary form of validation.
In next part we will learn more about Validation Framework in Struts2 and implement it in our example.
Our Login Action contains the method execute() which is the default method getting called by Sturts2. authenticate(); then we should specify the method name in We are almost done with the application.
The Text Provider interface defines several method that we must implement in order to get hold on get Text() method. We just have to extend our Login Action class with this class and directly use methods such as get Text(), add Action Errors() etc.
First of all click on New Project and the Dynamic Web Project.
This will create a web project in Eclipse which can be exported as war file and run on Tomcat 6 server. The following jar files should be added to the project for successful deployment of struts project : We have registered Action Servlet class in for the url “*.do” , that means every url that ends with “.do” will be taken care by Struts.
We will define an Application Resources.properties file for our application.
This property file should be present in WEB-INF/classes folders when the source is compiled.

If you have not gone through the previous article, I highly recommend you to do that before starting hands-on today. Once this is done, select the target runtime environment (e.g. This is to run the project inside Eclipse environment. Once the project is created, you can see its structure in Project Explorer.
