Jboss + Tomcat and Database Stored Sessions

[Hugo Kotsubo <hu...@tendencies.com.br>]

Hi!

I'm using Jboss  3.2.1 with Tomcat 4.1.24, and Tomcat is running as a 
Jboss MBean.

I want to control the number of sessions each application can have. To 
do this, I'm trying to store
sessions in a postgresql database, and use the Tomcat PersistentManager 
Implementation.

The tomcat configuration is under the Jboss deploy directory, at the 
following path:

/opt/jboss/server/default/deploy/jbossweb-tomcat.sar/

In this directory I have all the jar files needed by tomcat, a web.xml 
file and a META-INF directory, with a manifest file and a jboss-service.xml file (shown below)

I guess that something is wrong with one of the xml files.
Can anyone help me?

thanks

     In order to activate HTTP Session clustering for Tomcat
     make sure you run JBoss's "all" configuration i.e.
     "run -c all"
     (the default configuration doesn't contain clustering)
     Furthermore, you may change SnapshotMode and
     SnapshotInterval attributes below to indicate when to
     synchronize changes with the other node(s).
     If you use Apache+mod_jk(2) you will most probably use
     the AJP1.3 connector below. Thus, if you so wish,
     you may comment (i.e. deactivate) the HTTP connector
     as it won't be used anymore.

     If you are using clustering, the following two attributes
     define when the sessions are replicated to the other nodes.
     The default value, "instant", synchronously replicates changes
     to the other nodes. In this case, the "SnapshotInterval" attribute
     is not used.
     The "interval" mode, in association with the "SnapshotInterval"
     attribute, indicates that Tomcat will only replicates modified
     sessions every "SnapshotInterval" miliseconds at most.
