[SCXML] Java-scxml interaction

[Anna Klisiewicz <an...@googlemail.com>]

Hi

I don't know how to make bridging between scxml and java possible.

In my program first I run the state machine. In some of the states, I would
like to ask user questions (together with the transitions) and come back to
the execution of state machine after getting an answer. How to do it?

I tried triggering events, but I am not sure if that's the right way. What
about listener?..

Thank you, Anna

I'm going to remain distracted for another week or so -- and in terms
of the original question(s) in this thread, I'd recommend going back
to the W3C draft, understanding the semantics of the various available
techniques (be it <send>, custom actions, <invoke> etc.) and choosing
one that is appropriate for your needs. From what you've said so far,
invoke seems to have viable semantics for the usecase.

Using <param> is correct, and often the only way to pass data since
the <invoke>'d service executes in its own context (i.e. has a
separate datamodel).

Not actual anymore - I think I have done it with invoker.

By the way, how to get access to datamodel? So far I was doing it in the
same function where I was executing SCXML. now I want use them in conditions
in Invoke function. Shall I send them by "param" or is there more
convienient way, like "getData()" or something

Hello,

I need this this info very much:(... I am trying to do something with
<invoke> now. Is it a good way? If yes, can I please have any examples.
