	Deploying Reports in Web Applications		Documented by Luke Shannon

	Description / Goal	How to add reporting functionality to a Web application.
	Since	0.4.4

	Once a report is created the next challenge is to make this available to your report users. This sample reviews embedding a JasperReports template into a Java Application. The technology used are simple Servlets and JSP. This sample also demonstrates: Configuring and using several of the JasperReports exporters Viewing a report in Flash Viewing a report in an Applet Creating and using an XML Datasource Setting Up The Sample Prerequisites Ant is required. By running 'ant --version' you will be able to check if ant is set up on your system (at least version 1.5 is required): C:\>ant -version Apache Ant version 1.8.0 compiled on February 1 2010 You can obtain ant from http://ant.apache.org/, instructions for installation can be found there as well. Also before generating this sample you will need to run the jar ant command in the build file at the in the root of the project. This will generate JasperReports jar files in the dist directory of the root level. These jars are using in the web app sample, the sample will not function without them. Generating the Application Open up a separate command prompt/terminal window and browse to the root directory of the sample. By running 'ant -p' you will be presented with a list of options available. Of interest in this list is all the exporters available for testing. By running the command 'war' the following actions will be performed: All the dependancies will be copied to the WEB-INF\lib directory All required Java classes will be compiled The dependancies, class files and any other files will be packaged into a war file The war file will be generated in the root level of the project. This file can be deployed in a Java application server such as Tomcat (simply place the file in the webapps folder and restart the server). You now have a working version of the app you can review.
