Thanks for your response.

I'm not familiar with using a JSP (assume are we talking Java Server
Pages?) in the context of my application.  Mine is a stand-alone Java
GUI application using Swing with the state machine to respond to user
actions and other system actions.  Is there a way to use a dynamic
resource without using JSP?  If so, what would an example look like?

Thanks a bunch,
Cheryl

result in duplicated state names.  I have studied the tutorial in
http://wiki.apache.org/commons/SCXML/Tutorials/Templating, and the very
last paragraph under "A word of caution" I think contains the key to a
solution for me.  It says that the duplicated names "can be avoided by
using a param=value after the URL" as it mangles the URL.  Does anyone
have an example usage of this?

Not sure what the sentence in question on the wiki means either.

However, lets replay the example, say we have this reusable template
(lets call it template.scxml):

template.scxml:
<scxml ...>

    <state id="foo">
    ...
    </state>

    <state id="bar">
    ...
    </state>

</scxml>

where foo and bar do interesting things that we want to reuse in our
main.scxml. If we reference this static document multiple times like
so:

main.scxml:
<scxml ...>

    <state id="s1" src="template.scxml">
    ...
    </state>

    <state id="s2" src="template.scxml">
    ...
    </state>

</scxml>

we'll get ID clashes (for IDs foo and bar, included twice).

However, if we reference a dynamic resource (such as a JSP, lets call
this template.jsp) which allows us to tweak the IDs like the one
below:

template.jsp:
<%@ page info="SCXML template" %>
<scxml ...>

    <state id="foo${param.suffix}">
    ...
    </state>

    <state id="bar${param.suffix}">
    ...
    </state>

</scxml>

and then we reference the reusable pattern like so in our main.scxml:

main.scxml:
<scxml ...>

    <state id="s1" src="template.jsp?suffix=1">
    ...
    </state>

    <state id="s2" src="template.jsp?suffix=2">
    ...
    </state>

</scxml>

we wouldn't get any ID clashes (since we now have states with ID foo1
and bar1 as children of s1 and foo2 and bar2 as children of s2).
