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:
   Java

   <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:
   Java

   <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:
   Java

   <?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:
   Java

   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.
