Red Hat technical sesssion Luxembourg, Thursday August 25, 2011

Dear *,

On August 25th we are organizing a special technical afternoon session for our customers and partners. Red Hat can help customers plan their IT infrastructure – from Open Source Software to Virtualization, Cloud Computing and much more. This technical session will inform you about Red Hat Enterprise MRG, CloudForms and JBoss as a Fabric (Openshift). It will also provide you with the possibility to discuss technical issues with Red Hat experts and your peers.

MRG Used by many financial institutes, Red Hat Enterprise MRG is a next-generation IT infrastructure incorporating Messaging, Realtime, and Grid functionality. It offers increased performance, reliability, interoperability, and faster computing for enterprise customers.

CloudForms CloudForms redefines the IaaS cloud market by incorporating both comprehensive application lifecycle management and the ability to create integrated clouds from the broadest range of computing resources with unique portability across physical, virtual, and cloud computing resources.

JBoss as a Fabric (Openshift) At Red Hat, we have been working hard towards a broad and open cloud stack that covers everything from IaaS through PaaS to SaaS. Among these, PaaS will likely be of most interest to the JBoss developer. But what exactly is this “platform”? What am I, as a developer, going to code against? And what am I, with my operator hat on, going to monitor and manage?

We will close this meeting with networking drinks and snacks.

Registration Join us for this exclusive technical session. Spaces are limited so register today to ensure your place. Please send an e-mail with your contact details to redhat@artdcom.com.

We look forward to meeting you on August 25th!

[JBoss] How to restrict access to JSF pages when user are not logged In ?

 

 

 

 

 

 

 

Dear *,

Here was the problem. One our client decided to not use Seam and do everything by himself. – Why reinvent the wheel ? -

Well, so he had an issue with the web page access which needs to have credentials. They were accessible by everyone if you knew the URL.

So the solution was to use servlet filter:

So create the Authentication filter implementation  named Authentication.java for instance :

package com.jboss.eas.project;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

public class Authentication implements Filter {
private FilterConfig customedFilterConfig;

public void doFilter(ServletRequest req, ServletResponse resp,FilterChain chain) throws IOException, ServletException {

if (((HttpServletRequest)req).getSession().getAttribute(Login.AUTH_KEY) == null) {
((HttpServletResponse)resp).sendRedirect(“../Non_Authorized_login.xhtml”);
} else {

chain.doFilter(req, resp);
}
}

public void init(FilterConfig customedFilterConfig) throws ServletException {
this.customedFilterConfig = customedFilterConfig;
}

public void destroy() {
customedFilterConfig = null;
}
}

Then create a login bean or adapt yours – e.g. here Login.java -  :

package com.jboss.eas.project;

import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;

public class Login {
public static final String AUTH_KEY = "username";

private String username;
public String getUsername() { return username; }
public void setUsername(String username) { this.username = username; }public boolean isLoggedIn() {
return FacesContext.getCurrentInstance().getExternalContext()
.getSessionMap().get(AUTH_KEY) != null;
}public String login() {
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put(
AUTH_KEY, username);
return “true”;
}public String logout() {
FacesContext.getCurrentInstance().getExternalContext().getSessionMap()
.remove(AUTH_KEY);
return null;
}
}

 

Then add the following stanzas in your web.xml file :

 

<filter>

  <filter-name>Authentication</filter-name>

  <filter-class>com.jboss.eap.project.Authentication</filter-class>

</filter>

<filter-mapping>

  <filter-name>Authentication</filter-name>

  <url-pattern>/Authorized_Web_Pages_Access_Directory_Path/*</url-pattern>

</filter-mapping>

BTW, the “Authorized_Web_Pages_Access_Directory_Path" is the directory which contains all your protected web pages.

Then create a Error redirection web page in case of an access to a web page without credentials  – here Non_Authorized_login.xhtml -

<html>
<head>

You do not have access to this page. <p></p> You must be registered !

</head>
</html>

 

Finally create your xhtml or jsf page – here AuthenticatedLogin.xhtml -

 

<f:view>

 <h:form> Username:

  <h:panelGroup rendered="#{not login.loggedIn}">

    <h:inputText value="#{login.name}" />

    <h:commandButton value="login" action="#{login.login}" />

  </h:panelGroup> <h:commandButton value="logout" action="#{login.logout}" rendered="#{login.loggedIn}" />

 </h:form>

</f:view>

 

Here should be the result when you try to access a page without successful logged in using its URL  :

[JBoss.org] servlet-api question

Dear *,

Yesterday someone asked me how to include  javax.servlet-3.0.jar in his JBoss AS 7 Project in using Maven.

My answer was to go to the JBoss community repository web interface – see URL below -
and search for the “servlet-api” then insert in his project’s pom.xml the follwoing content under the <dependencies></dependencies> stanzas :

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>3.0</version>

<scope>provided</scope>

</dependency>
