Scott and CAS Development Team,
We are using org.jasig.cas.ticket.registry.JBossCacheTicketRegistry in a
clustered environment. The underlying tree cache is from
JBossCache-1.4.1.SP3. Our jbossCache.xml is listed below (which is
virtually identical to the cas server release provided sample).
We are having no problems running cas-server.3.0.7 out of the box with
this configuration.
However, during Spring Framework based cas login web flow, when we
attempt to add our own login ticket (a class or our own making which
extends org.jasig.cas.ticket.AbstractTicket and implements
org.jasig.cas.ticket.TicketGrantingTicket in like manner to
org.jasig.cas.ticket.TicketGrantingTicketImpl) to the jboss cache (as in
org.jasig.cas.ticket.registry.JBossCacheTicketRegistry.addTicket(loginTi
cket)), the method throws the java.lang.RuntimeException: "failure to
marshal argument(s)".
In addition, if we remove from the jboss cache ticket registry (as in
org.jasig.cas.ticket.registry.JBossCacheTicketRegistry.deleteTicket(tick
etGrantingTicketId)) an already successfully added ticket granting
ticket (as in
org.jasig.cas.CentralAuthenticationService.createTicketGrantingTicket(cr
edentials)), and then attempt to add it back (as in
org.jasig.cas.ticket.registry.JBossCacheTicketRegistry.addTicket(ticketG
rantingTicket)), we get the same exception.
Note that this exception is thrown regardless of whether or not the
jbossCache.xml UseMarshalling attribute is set to true of false.
What is the explanation for this and how can we achieve adding
org.jasig.cas.ticket based classes of our own making to the jboss cache
ticket registry?
Thanks very much.
Lee
