Hi Q,
I am thinking of using Scala with WebObjects...yes.
Typically deadlocks are more likely to be caused by your own code, rather than the underlying frameworks.
This assumes you're using Wonder/WO/EOF in a thread-safe manner.
i.e you are taking the necessary precautions for EOF (like turning off shared EOs, auto lock/unlocking of ECs, etc).
Broadly speaking, Scala is safer to use than Java for developing a concurrent request handling app because of its lack of static variables and methods, use of separate mutable/immutable datatypes and collections, etc.
Using Ajax (i.e asynchronous communication) with WO is where the need for concurrent request handling and better thread-safety come in...
Thanks,
Ravi
