I just downloaded JBoss 4.0.5 and thought I would try, yet again, to get
non-sticky-session load-balancing working, but alas, I have failed again, for
the 93rd time!
I'm running 4.0.5 in the "all" configuration on two machines (my PowerBook and
a Solaris 10 x86, not that it matters) on the LAN here. I have turned on using
mod_jk in the Tomcat jboss-service.xml and enabled JBoss clustered SSO in the
server.xml (as well as added jvmRoute to the Engine element). Then I tweaked
tc5-cluster.sar to do REPL_SYNC and turned on buddy replication. The two
servers find each other just fine and all my jars and wars are deployed across
the cluster.
When I try to log into the web app, though, it prompts me to log in twice, then
gives me a 404 error. So, obviously, session replication is not happening
(prompting me to log in once per node--last time I tried this with 4 nodes and
I was prompted to log in 4 times) and there's something odd going on with the
404 error, given the URL I'm accessing is a virtual one and is recognized only
by the servlet in my webapp. I know my webapp is being deployed, because the
TomcatDeployer says so and it recognizes that I have "distributable" set in the
web.xml.
Any help you can give here would be greatly appreciated! I've included relevant
snippets from my config files below:
from jbossweb-tomcat55.sar/META-INF/jboss-service.xml...
<attribute name="UseJK">true</attribute>
jbossweb-tomcat55.sar/server.xml...
<Engine name="jboss.web" defaultHost="localhost" jvmRoute="172.16.10.22">

| worker.router.balance_workers=localhost,portalvm
| worker.router.sticky_session=false

Everything else is stock.
Thanks!
