+================
+
+This demo showcases the integration with XML technologies in the service assembly.
+
+Note: The live currency exchange rate RSS feed and the live stock quote web service are not always running.
+When this happens, the demo code uses historical data instead of live data.
+
+To run the demo, do the following:
+
+cd xml-bigbank
+ant run
+
+You should see output similar to the following:
+
+Buildfile: build.xml
+
+run:

+ Ideally we would obtain the WSDL from the remote server using <wsdl:import location="..."/>, but this
