Hi, This is a getting started tutorial for struts-2. Struts-2 is similar to struts-1 but there are certain changes in terms of functionality and syntax. The main components needed to create the demo application are as follows: 1. Eclipse indigo. 2. Struts-2 distribution:- To download struts-2 distribution go to 'http://struts.apache.org/download.cgi#struts238-SNAPSHOT' and download 'Full Distribution: struts-2.3.7-all.zip (76mb) [ PGP ] [ MD5 ] ' 3. Tomcat 7. That is all you need to create a struts application. Application Structure: The demo application that we are going to create using struts-2 is a login application. The application will be having following components: 1. index.jsp 2. HelloWorld.jsp 3. error.jsp 4. HelloWorldAction.java Now the application proceeds as follows: 1.

So we will be using the base domain URL as ' http://localhost:8080/ '.

Step 1 (Eclipse setup): a. Create a 'Dynamic Web Project' in eclipse indigo. Let us say that thi

This is again a "getting started tutorial" of how to start using XML parsing concepts in java. For further details of using XML parsing please refer tutorials at : http://docs.oracle.com/javase/tutorial/jaxp/sax/index.html . The program presented here is a simple demonstration of how to parse an XML document using SAX-XML parser for java. For demonstration purpose a sample .xml file is also included. temp.xml : <?xml version="1.0"?> <company>     <staff department="information security">         <firstname>FIRST NAME-1</firstname>         <lastname>LAST NAME-1</lastname>         <nickname>STUDENT-1</nickname>         <salary>100000</salary>     </staff>     <staff>         <firstname>FIRST NAME-2</firstname>         <lastname>LAST NAME-2</lastname>         <nickname>STUDENT-2</nickname>         <salary>200000</salary
