How to Implementation JSF Chart in JSF
Many times we have requirement of displaying data using charts in our web application. Jsf-comp is a opensource library which I have used in my JSF application. I have used this for simple bar charts and using it is very simple. Below I have explained steps to use it in your application to create a bar chart.
Here I assume you have already had a jsf application running. If you are new to JSF, please read the earlier post JSF tutorial For Beginner .
For the bar chart demo we’ll create a request scoped bean, and a simple jsf view. The data displayed in charts will be some predefined values.
Step 1: Configuration.
Before starting the code download jsf-comp jar file ( jfreechart-1.0.5.jar) from url:
http://sourceforge.net/projects/jfreechart/files/
Copy the jar to web-inf/lib directrory.
Edit your web.xml file to include following:
<servlet>
<servlet-name>Chartlet</servlet-name>
<servlet-class>net.sf.jsfcomp.chartcreator.Chartlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Chartlet</servlet-name>
<url-pattern>*.chart</url-pattern>
</servlet-mapping>
Step 2: Backing bean part.
To create any chart we need object of DefaultCategoryDataset (org.jfree.data.category.DefaultCategoryDataset)
DefaultCategoryDataset categoryDataSet=new DefaultCategoryDataset();
We set graph values in this object using addValue function. The functions is shown below (create a Weather.java and include following function with appropriate getter and setter methods) :
package com.sa.medisys.banamco.chart;
import org.jfree.data.category.DefaultCategoryDataset;
public class Weather {
public Weather(){
}
public DefaultCategoryDataset getGraphData() {
DefaultCategoryDataset categoryDataSet=null;
try{
categoryDataSet = new DefaultCategoryDataset();
Double currentTemperature= 25.3;
//Easy AdSense by Unreal
Double minTemperature=10.2;
Double maxTemperature=45.0;
Double avgTemperature=30.0;
categoryDataSet.addValue(maxTemperature,"","Highest Temperature");
categoryDataSet.addValue(minTemperature,"","Lowest Temperature");
categoryDataSet.addValue(avgTemperature,"","Average Temperature");
categoryDataSet.addValue(currentTemperature,"","current Temperature");
return categoryDataSet;
}catch(Exception sq){
System.out.println("exception2 " +sq);
sq.printStackTrace();
return null;
}
}
}
Define the bean in the faces-config.xml file as Managed Bean:
<managed-bean>
<managed-bean-name>weather</managed-bean-name>
<managed-bean-class> com.sa.medisys.banamco.chart.Weather</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
Now in xhtml file you can use the chart library as follows:
Include tag library definition:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:ch="http://sourceforge.net/projects/jsf-comp">
<ui:composition >
<h:outputText value="chart Display" />
<ch:chart id="pichart" datasource="#{weather.graphData}" type="bar" background="orange" orientation="vertical" is3d="false" title="Compare the Temperatures" xlabel="" ylabel="Temperature" height="300" width="500"></ch:chart>
</ui:composition>
</html>
Run the jsf file to see the chart.

How to configure Session timeout in jsf
How to Configure Session Timeout in jsf
How to Configure Session Timeout in jsf
Step 1.Create Listener Class such as MySessionListener.java
package com.session;
public class MySessionListener implements HttpSessionListener {
public MySessionListener() {
}
public void sessionCreated(HttpSessionEvent event) {
System.out.println("Current Session created : "+ event.getSession().getId() + "at "+ new Date());
}
public void sessionDestroyed(HttpSessionEvent event) {
// get the destroying session…
HttpSession session = event.getSession();
System.out.println("Current Session destroyed :" + session.getId() + "Logging out user");
/*
* nobody can reach user data after this point because session is invalidated already.
* So, get the user data from session and save its logout information
* before losing it.
* User’s redirection to the timeout page will be handled by the SessionTimeoutFilter.
*/
// Only if needed
try {
prepareLogoutInfoAndLogoutActiveUser(session);
} catch(Exception e) {
System.out.println("Error while logging out at session destroyed : " + e.getMessage());
}
}
/**
* Clean your logout operations.
*/
public void prepareLogoutInfoAndLogoutActiveUser(HttpSession httpSession) {
// Only if needed
}
}
Step 2.Create Filter Class SessionTimeoutFilter.java
package com.session;
/**
*When the session destroyed, MySessionListener will do necessary logout operations.
* Later, at the first request of client, this filter will be fired and redirect
* the user to the appropriate timeout page if the session is not valid.
*/
public class SessionTimeoutFilter implements Filter {
// This should be your default Home or Login page
// "login.index" if you use Jboss Seam otherwise "login.jsf" / "login.xhtml" or whatever
private String timeoutPage = "/LOG001.jsf";
public void init(FilterConfig filterConfig) throws ServletException {
}
public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws IOException, ServletException {
if ((request instanceof HttpServletRequest) && (response instanceof HttpServletResponse)) {
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
HttpServletResponse httpServletResponse = (HttpServletResponse) response;
// is session expire control required for this request?
if (isSessionControlRequiredForThisResource(httpServletRequest)) {
// is session invalid?
if (isSessionInvalid(httpServletRequest)) {
String timeoutUrl = httpServletRequest.getContextPath() + "/" + getTimeoutPage();
System.out.println("Session is invalid! redirecting to timeoutpage : " + timeoutUrl);
httpServletResponse.sendRedirect(timeoutUrl);
return;
}
}
}
filterChain.doFilter(request, response);
}
/*
* session shouldn’t be checked for some pages. For example: for timeout page..
* Since we’re redirecting to timeout page from this filter,
* if we don’t disable session control for it, filter will again redirect to it
* and this will be result with an infinite loop…
*/
private boolean isSessionControlRequiredForThisResource(HttpServletRequest httpServletRequest) {
String requestPath = httpServletRequest.getRequestURI();
boolean controlRequired = !StringUtils.contains(requestPath, getTimeoutPage());
return controlRequired;
}
private boolean isSessionInvalid(HttpServletRequest httpServletRequest) {
boolean sessionInValid = (httpServletRequest.getRequestedSessionId() != null)
&& !httpServletRequest.isRequestedSessionIdValid();
return sessionInValid;
}
public void destroy() {
}
public String getTimeoutPage() {
return timeoutPage;
}
public void setTimeoutPage(String timeoutPage) {
this.timeoutPage = timeoutPage;
}
}
Step -3
1. Put jar file commons-lang-2.4 into lib folder
2. Change web.xml file
<filter>
<filter-name>SessionTimeoutFilter</filter-name>
<filter-class>com.session.SessionTimeoutFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>SessionTimeoutFilter</filter-name>
<url-pattern>*.jsf</url-pattern>
</filter-mapping>
<listener>
<listener-class>com.session.MySessionListener</listener-class>
</listener>
