Look carefully in you stateful sessionbean for any non-serializable
field. If you want them there you have to declare them transient and
they will not be passivated which also means that they will loose their
data when passivating.

Hi,
I have an issue regarding the configuration files (specially jboss.jcml) used
with JBoss 2.4.6. The problem is configuration of the pools to the databases,

I'm really sorry for the stupid question, but can someone point me to a

In Tomcat I use the tomcat-users.xml, where is such a file

yeah ReadAheadCache is currently the HotSpot. I think Dain did some
optimizations for that in 3.2 which haven't made it into 3.0 just yet?

Correct!
Now it is split into jasper-compiler.jar and jasper-runtime.jar and
both reside under jetty/ext/.

Yes, that would be really interesting. We really need to find out why going
to the DB (in-VM DB at least... ouf...) is faster than retrieving from
cache.

Hi Stefan,
JBoss uses JAAS.
For a simple file based login module and how it is used have a look at
the jmx-console web application that comes with Jboss.
Have a look at these config files:
Jboss/server/all/conf/login-config.xml (application-policy
jmx-console)
In all jboss 3 and later versions, you can supply the db login credentials
from a jaas login module. This can obtain the credentials from anywhere
you can think of.
I'm not a security expert, but I've always wondered how to make such a
scheme actually secure, since the ways I've thought up
I'll try to get it done in the next day or so.
