Re: XLANG, WSFL response on solicit-response and output-only

Dear all experts:
 
 I am currently investigating a new technology to compose several other
web services. I know that both XLANG and WSFL are standard
specifications which can be used for our purpose.  Could any of you
point out which software (tools ) can provide a work environment so that
I can compose a workflow model and run it?  Is it possible to monitor
the states of execution and interact with the workflow during the run?
 
 I really appreciate it whatever help you can provide.
