Spring Web MVC - Spring Web Flow Working With JasperReports

Step 1: Creating the structure folders

To do this tutorial quickly and easily, create a Tomcat project called springjasperreports in the webapps folder of your Tomcat installation. I will show you a structure of all folders inside the project (would change according your logic). At first glance it can be a little confusing but later it will be easier to understand.

Step 2: Configuring web.xml

<display-name>springjasperreports</display-name>
	<context-param>
		<param-name>webAppRootKey</param-name>
		<param-value>springjasperreports.root</param-value>
	</context-param>
	<session-config>
        	<session-timeout>60</session-timeout>
	</session-config>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
				/WEB-INF/springjasperreports-servlet.xml		
				/WEB-INF/xml/context/applicationContext-swf.xml			
				/WEB-INF/xml/context/applicationContext-jasperreports.xml
				/WEB-INF/xml/context/applicationContext-jasperreportsengine.xml		
		</param-value>
	</context-param>
	
    <servlet>
    	<servlet-name>springjasperreports</servlet-name>
    	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	    <init-param>
    	  <param-name>detectAllViewResolvers</param-name>
      	  <param-value>false</param-value>
	    </init-param>
  	</servlet>
	
	<listener>
    	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
    <servlet-mapping>
  	  <servlet-name>springjasperreports</servlet-name>
      <url-pattern>*.htm</url-pattern>
  	</servlet-mapping>

  	<welcome-file-list>
	  <welcome-file>index.jsp</welcome-file>
  	</welcome-file-list>
  	
  	<taglib>
		<taglib-uri>/spring</taglib-uri>
		<taglib-location>/WEB-INF/spring.tld</taglib-location>
	</taglib>

An important part would be contextConfigLocation, there you can see

• /WEB-INF/springjasperreports-servlet.xml (for view resolver,url mapping, and some Web MVC beans)
• /WEB-INF/xml/context/applicationContext-swf.xml (for flow configuration)
• /WEB-INF/xml/context/applicationContext-jasperreports.xml (for a controller to handle a request )
• /WEB-INF/xml/context/applicationContext-jasperreportsengine.xml (for our report engine)
