[JBoss-user] [Clustering/JBoss] - Re: Session not replicated in JBoss 3.2.6
Yes, that was the problem. In order to have the same information in the session, I have to use sticky sessions (so only one JBoss instance is used for a certain session). But having in mind that I want to have the same session data on both JBoss instances, I had to upgrade to JBoss 4.0.2 (which can do this, so now everything I wanted is working great). Thank you Ben for your answers.

[JBoss-user] [Clustering/JBoss] - Re: Session not replicated in JBoss 3.2.6
Hi Ben, and thank you for your answer.
I have a load balancer in front of the cluster. Using Apache 2.0.54 with mod_jk
1.2.12, and this is my configuration:
jk.conf:
| LoadModule jk_module modules/mod_jk.so
|
| # The workers.properties
| JkWorkersFile conf.d/workers.properties
|
| # The log files
| JkLogFile logs/mod_jk.log
|
| # Set the jk log level
| JkLogLevel info
|
| # Select the log format
| JkLogStampFormat {%a %b %d %H:%M:%S %Y}
|
| # JkOptions indicate to send SSL KEY SIZE
| JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
|
| # JkRequestLogFormat set the request format
| JkRequestLogFormat %w %V %T
|
| JkShmFile /usr/local/apache/logs/shm
|
| JkMount /test* loadbalancer
|
| #Add jkstatus for managing runtime data
| Location /jkstatus/
|JkMount jkstatus
|Order deny,allow
|Allow from all
| /Location
|
and workers.properties:
| # Define the first node...
| worker.node1.port=8009
| worker.node1.host=192.168.1.254
| worker.node1.type=ajp13
| worker.node1.lbfactor=1
| #worker.node1.local_worker=1
| worker.node1.cachesize=10
|
| # Define the second node
| worker.node2.port=8009
| worker.node2.host=192.168.1.2
| worker.node2.type=ajp13
| worker.node2.lbfactor=1
| #worker.node2.local_worker=1
| worker.node2.cachesize=10
|
| # Now define the load-balancing behaviour
| worker.loadbalancer.type=lb
| worker.loadbalancer.balanced_workers=node1,node2
| worker.loadbalancer.sticky_session=1
| #worker.loadbalancer.local_worker_only=1
|
| # Define the status worker
| worker.jkstatus.type=status
|
| worker.list=loadbalancer,jkstatus
|
As I said before, I made a simple application to test the session replication.
It contains a servlet and a jsp. The servlet contains this code:
| Hello world JSP on %= new java.util.Date() %
|
| br
|
| The session date is: %= request.getSession().getAttribute(date) %
|
and the servlet is this:
| protected void doGet(HttpServletRequest request,
| HttpServletResponse response) throws IOException {
| response.getWriter().println(Hello world on + new Date());
|
| String newDate = (new Date()).toString();
| System.out.println(Storing date: +newDate);
|
| request.getSession().setAttribute(date, newDate);
| }
|
I noticed something very interesting. If I start both JBosses and the very
first thing I call is the servlet, the attribute date is set on both JBosses,
so everything works fine (if I refresh the JSP page, because of the load
balancer settings it goes to a different JBoss each time, and the date is there
and it is the same for both). Now, I call again the servlet and from now on,
the date is set only on the JBoss where I called the servlet (so the session is
not replicated anymore from now on). The same happens (session attribute not
set on both JBoss) if the first thing I call after starting JBosses is the JSP
page. If I do this, the session attribute is only set on the JBoss I call the
servlet.
Perhaps I should mention that the Apache server is located on the same computer
with one of my JBoss instanced (192.168.1.254). The other JBoss instance is
located on another computer (192.168.1.2).
Another thing I noticed is that I have this in the JBoss logs:
[STDOUT] Can't find resource org.jboss.web.tomcat.session.LocalStrings [EMAIL
PROTECTED]
[STDOUT] [Ljava.net.URL;@117ee94
but I readed on another post that this is harmless.
Any idea is welcome. Thank you.

[JBoss-user] [Clustering/JBoss] - Re: Session not replicated in JBoss 3.2.6
Perhaps I should mention that I'm using Fedora Core 2. Could this be a problem ? (I readed somewhere that nobody made a cluster work on FC3. I don't know if this is true or false and if it also apply for FC2 ).

Hello everybody, I hope somebody can help me solve this problem. I'm using Jboss 3.2.6 in a clustered environment.

[JBoss-user] [Clustering/JBoss] - Re: Tomcat-LoadBalancer-Jboss problem
Hello, maybe you can check your mod_jk log (I assume you have mod_jk for Apache - Tomcat load balancer). I think it would be useful if you post the jk.conf, workers.properties and the mod_jk log file.
