    Multiple domain names (Virtual Domain names) on JBoss AS

    Jonathan Ekwempu Newbie

      Hi All,

      I have done an extensive research/search on the
      internet but did not get a suitable solution on how to
      configure multiple domain names (Virtual Domain names)
      on JBoss AS (running Tomcat) in a Linux environment. I
      do not want to use multiple IPs on the same server.

      Essentially, I have two domain names MyDomain1.com and
      MyDomain2.com. I want to be able to deploy different
      ear applications on the server so that clients of
      MyDomain1.com can enter http://www.MyDomain1.com in a
      browser and start Application1. Similarly, clients of
      MyDomain2.com can enter http://www.MyDomain2.com in a
      browser and start Application2. Application1 is
      completely independent of Application2 and belong to
      two different organizations.

      I have already set up a DNS server that resolves the
      two domains to the same Ip address.

      Has any body done anything like that? Is it even
      possible to do so in a JBoss (with Tomcat) AS?

      If you have a solution, kindly let me know how you did
      it or you could point me to a good reference document.

      I am using JBoss 4.0.2 and Fedora Linux kernel 2.4.26
      in a dedicated server hosted by an ISP.

      Thanks,

      Jonathan

          Thanks to all.

          This setup has been tested on Apache2+JBoss+mod_jk-1.2.14_for MacOSX. And am sure it will work on other platforms as well. This setup also handles Apache related webapps..

          Make the required entries in the DNS

          webapp.war: Extract the war file using zip and rename the folder
          with .war extension. Please put it in your deployment folder.

          mod-jk.so: Obtain the modjk.so library file from www.apache.org and place then in the modules folder.
