How to Setup seam3-Security in JBoss 7

Introduction

Recently, I've done some research on several Java Security Frameworks that can perform authentication, authorization and cryptography.

I've worked with Apache Shiro, it's really good and complete but I've found several problems like there's no default implementation for CDI interceptor for security annotations. Here's a sample implementation and setup that I did long ago.

And long time ago, I've used seam2-security and now I'm trying with seam3, here goes.

  1. I started by creating a javaee6 project generated from jboss maven archetype (ear type). This could also be done on a war type project of course (where the ejbs are in ejb project).
  2. In your main project maven's dependencyManagement section, add:
    <dependency>
     <groupId>org.jboss.seam</groupId>
     <artifactId>seam-bom</artifactId>
     <version>3.1.0.Final</version>
     <scope>import</scope>
     <type>pom</type>
    </dependency>

    This will ensure that we are using the correct seam-jar versions across our projects.

  3. And in the ejb project maven's dependencies section, add seam3-security dependency:
    <dependency>
     <groupId>org.jboss.seam.security</groupId>
     <artifactId>seam-security</artifactId>
     <scope>compile</scope>
    </dependency>
  4. In web project, create a beans.xml file in WEB-INF folder. This file is also required for CDI to work. And here we define the interceptor:
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns:s="urn:java:ee" xmlns:security="
     urn:java:org.jboss.seam.security"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
     http://jboss.org/schema/cdi/beans_1_0.xsd">
    
     <interceptors>
      <class>org.jboss.seam.security.SecurityInterceptor</class>
     </interceptors>
    
     <security:IdentityImpl>
      <s:modifies />
      <security:authenticatorClass>com.czetsuya.security.Authenticator
      </security:authenticatorClass>
     </security:IdentityImpl>
    
    </beans>
  5. Then we have to define the interceptor class:
    package com.czetsuya.security;
    
    import javax.enterprise.inject.Model;
    import javax.inject.Inject;
    
    import org.jboss.seam.security.BaseAuthenticator;
    import org.jboss.seam.security.Credentials;
    import org.picketlink.idm.impl.api.PasswordCredential;
    import org.picketlink.idm.impl.api.model.SimpleUser;
    
    @Model
    public class Authenticator extends BaseAuthenticator {
     @Inject
     Credentials credentials;
    
     public Authenticator() {
    
     }
    
     @Override
     public void authenticate() {
      System.out.println("logging in: " + credentials.getUsername());
    
      if ("demo".equals(credentials.getUsername())
        && credentials.getCredential() instanceof PasswordCredential
        && "demo".equals
        (((PasswordCredential) credentials.getCredential()).getValue())) {
    
       setStatus(AuthenticationStatus.SUCCESS);
       setUser(new SimpleUser("demo"));
    
      }
    
     }
    
    }
  6. To hide a component in the UI, you can use identity.hasPermission or identity.hasRole.
  7. You can download the source code from Google code.

As a programmer, I've worked on a wide variety of software development projects that had been deployed on different platforms (web, mobile, desktop). Although I learned and use an array of programming languages such as JavaEE6, asp.net, seam, php, android, xcode, etc. It's always been my favorite and priority to work with JavaEE6 and asp.net with the latest development they have (JavaEE6, MVC3, EF4). My expertise lies not only in programming but on software and database design as well, this is because I've been involved in the design of several custom software applications from scratch. Over the years I've worked on different positions like Developer, Software Engineer, Team Lead, Technical Lead and Project Manager, these experiences made me flexible and effective in the IT Industry.
