It sounds to me like the app is using servlet instance variables instead of method
variables for holding the userid.

Out of curiosity, what sort of things are you trying to accomplish via this
"scheduled" servlet invocation? Scheduling work to be done on a periodic basis is the
sort of thing that EJB 2.0 Message Driven Beans are good for.

If I am reading the spec correctly, you can initialize all of your properties
individually prior to setting them from the request params. I believe that the line
you quoted from the spec only applies when setting properties from request params.

Yes, MA88 supplies all you would need to use either the JMS api or the

You are correct. You can do the instantiation in a synchronized method to avoid the
issues with the static MQEnvironment variables.
However, I prefer to avoid synchronized methods when at all possible.

There are no apis in the servlet spec that allow a piece of code to see all the
