    Can you cluster an application that uses servlets, POJOs and

    a pan Newbie

      Hi I am writing a server application that uses servlets, Java Objects and database based logging.

      How can I use JBOSS to do clustering and load balancing? Or should I just use TOMCAT server. My opinion about tomcat is you can not cluster more than 2 or 3 servers as its memory requirement goes too high as it has to duplicate httpsesession to rest of the server every time servlet serves the request.

      Any suggestions? THanks,

          Ashish,
          You can use JBoss bundled TC instances to do clustering. I suggest you to do the following:
          a) Have a look at the Clustering Document written by Sacha Labourey which describes clustering for HTTP. [This document should be part of the free documentation].
          b) Have a look at the following wiki:
          http://www.jboss.org/wiki/Wiki.jsp?page=JBossHA

          JBoss clustering will be based on JBossCache over JGroups. Very soon(within a fortnight), you will have TreeCache/TreeCacheAop enabled for greater performance.

          With JBoss clustering, you can configure what session information you want replicated (all put_attribues, all gets, all sets etc). This way, syncronization between nodes and memory requirements is less. Have a look at the document I mentioned.
