Jboss + Tomcat and Database Stored Sessions

Hugo Kotsubo

2004-02-12




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

  The default value, "instant", synchronously replicates changes

  The "interval" mode, in association with the "SnapshotInterval"
