JBoss AS7

Is a Java application server Java EE 6 Full Profile http://download.jboss.org/jbossas/7.1/jboss-as-7.1.1.Final/jboss-as-7.1.1.Final.zip

Message driven bean (JBoss)

A message-driven bean is an enterprise bean that allows J2EE applications to process messages asynchronously.

Timers annotations

Creating Calendar-Based Timer Expressions http://docs.oracle.com/cd/E19226-01/820-7627/giqlk/index.html

Examples:

Every five minutes, @Schedule(minute = "*/5" , hour="*")
Every twenty minutes from 5 to 21, @Schedule(minute="*/20" , hour = "5-21")
At one AM, @Schedule(hour = "1")
At two AM and five PM, @Schedule(hour = "2,17")

JAAS security JBoss AS7

JAAS (Java Authentication and Authorization Service).

Read http://amatya.net/blog/implementing-security-with-jaas-in-jboss-as-7/

Basic authentication Web application

Add user and roles:

/opt/jboss-as-7.1.1.Final/bin/add-user.sh -a userx passx # add user userx
Files /opt/jboss-as-7.1.1.Final/standalone/application-users.properties and /opt/jboss-as-7.1.1.Final/domain/application-users.properties changed
vi /opt/jboss-as-7.1.1.Final/standalone/application-roles.properties # add primary role
userx=AppXYZUser # in application-roles.properties

Edit web.xml file for the web application:

   1 <web-app>
   2 <!-- other stuff .....-->
   3     <!-- security application realm -->
   4     <security-constraint>
   5         <web-resource-collection>
   6             <web-resource-name>HtmlAuth</web-resource-name>
   7             <description>application security constraints</description>
   8             <url-pattern>/*</url-pattern>
   9             <http-method>GET</http-method>
  10             <http-method>POST</http-method>
  11         </web-resource-collection>
  12         <auth-constraint>
  13             <role-name>AppXYZUser</role-name>
  14         </auth-constraint>
  15     </security-constraint>
  16     <login-config>
  17         <auth-method>BASIC</auth-method>
  18         <realm-name>ApplicationRealm</realm-name>
  19     </login-config>
  20     <security-role>
  21         <role-name>AppXYZUser</role-name>
  22     </security-role>    
  23     <!-- security application realm -->
  24 </web-app>

Edit jboss-web.xml

   1 <?xml version="1.0" encoding="UTF-8"?>
   2 <jboss-web>
   3   <context-root>/AppContextRoot</context-root>
   4   <security-domain>java:/jaas/other</security-domain> <!-- security application realm -->
   5 </jboss-web>

Forms login

The following input fields are posted when a login is attempted:

j_security_check
j_username
j_password

In web.xml:

   1     <login-config>
   2         <auth-method>FORM</auth-method>
   3         <realm-name>AppRealm</realm-name>
   4         <form-login-config>
   5             <form-login-page>/login.html</form-login-page>
   6             <form-error-page>/error.html</form-error-page>
   7         </form-login-config>
   8     </login-config>

JDBC authentication

For this setup the password is in plain text ! It must be improved in order to use hash like MD5 or SHA1.

Create tables on a PostgreSQL server:

psql -U userx -W -d databasex -h 192.168.1.1
\c databasex
create table users (username varchar(128) NOT NULL,password varchar(128) NOT NULL );
create table roles (username varchar(128) NOT NULL,role varchar(128) NOT NULL );
insert into users (username,password) values('userx1','12345678');
insert into roles (username,role) values('userx1','User');
insert into roles (username,role) values('userx1','UserManager');
grant all privileges on database dldserver to dldserver;
alter table users owner to userx;
alter table roles owner to userx;

Add security domain to standalone-full.xml:

   1 <security-domain name="jdbcRealm" cache-type="default">
   2  <authentication>
   3   <login-module code="Database" flag="required">
   4    <module-option name="dsJndiName" value="java:jboss/datasources/ServerDS"/>
   5    <module-option name="principalsQuery" value="SELECT password FROM users WHERE username=?"/>
   6    <module-option name="rolesQuery" value="SELECT role, 'Roles' FROM roles WHERE username=?"/>
   7    <module-option name="unauthenticatedIdentity" value="guest"/>
   8   </login-module>
   9  </authentication>
  10 </security-domain>

Alter jboss-web.xml:

   1 <jboss-web>
   2 <!-- ... -->
   3     <security-domain>java:/jaas/jdbcRealm</security-domain>
   4 </jboss-web>

JBoss5 clustering

http://docs.jboss.org/jbossclustering/cluster_guide/5.1/html/clustering-intro.chapt.html

Clustering allows you to run an application on several parallel servers (a.k.a cluster nodes) while providing a single view to application clients. Load is distributed across different servers, and even if one or more of the servers fails, the application is still accessible via the surviving cluster nodes. Clustering is crucial for scalable enterprise applications, as you can improve performance by adding more nodes to the cluster. Clustering is crucial for highly available enterprise applications, as it is the clustering infrastructure that supports the redundancy needed for high availability.
