Fetch Data in JSON Format

As the following sample demonstrates, the fetched resource can return data in JSON format. The data can then be parsed by an SCXML session. Note that in this example the result of the parsing is stored in the Target global variable.

Fetched file content: File http://localhost:9090/strategies/01_BASIC/_aux/GetDate.jsp

<%="{\"year\":2008, \"month\":\"December\", \"date\":25}"%>
