How to install install and configure SSL on JBoss 5.1

The reason for installing SSL (Secure Socket Layer) is to protected the data received and sent to be read in clear text and instead received and sent encrypted.

The first you need is a Server Certificate. You can get a valid Certificate from Certification Authority (CA) like Thwate, Verisign and many more. But here I will use a self-signed certificate but the process is quite similar for the ones from a Certification Authority (CA). Remember that the first and last name should be either your domain address or machine name.

And to view your self-signed certificate: Now you need configure your HTTPS Connector.

$JBOSS_HOME/server/$JBOSS_CONF/deploy/jbossweb.sar/server.xml: There are several more configuration for the Connector which you can read more about here for JBoss 5.1:
http://docs.jboss.org/jbossweb/2.1.x/config/http.html

And the latest documentation is found here:
http://docs.jboss.org/jbossweb/latest/config/http.html

The last thing we need is a test application I will leave that as a practice, but I will show one interesting part and that is the web.xml

Now open you web browser and test your application. To do the same for Tomcat is quite similiar, read more about it in my next blog - http://magnus-k-karlsson.blogspot.se/2012/06/how-to-install-install-and-configure.html.
