Hello All , I am a newbie to the Tomcat and Tomcat clustering environment .I was just going through some posts on this forum for reference . I wish to deploy the classic JPetStore application which comes with the Spring framework in the clustered environment involving 2 machines
For this, I installed Apache 2.2 , Tomcat 6.0.18 and mod_jk on each of these machines . I configured mod_jk load balancer for sticky session and deployed JPetStore on either of them . But once I start tomcat and apache on either machine and try to do some transactions , I cannot see any sessions being exchanged between the two members of the cluster. The JPetStore application also uses a database (hsqldb) and its necessary to start one on either machine (it is not a shared one). I was reading some documentation regarding if the session attributes are to be implemented from serializable interface...but I see they already have been in the source code . I will be greateful if anyone could help me out and give a good insight on where I am going wrong ? I have attached the server.xml , workers.properties and catalina.out for the two nodes in the attached file. Any help is deeply appreciated ! Best Regards !!
