"java.lang.NoClassDefFoundError" is logged in Streaming Integrator Tooling M4 and M7 packs when trying out XML custom mapping

[RukshiW]

Description:

The following are the steps followed:

1. Create an XML file with the following content:

   <?xml version="1.0" encoding="UTF-8"?>
   <flights>
    <flightevent>
       <flight>QR-1405</flight>
       <details>
          <destination>lisbon</destination>
          <passengers>200</passengers>
          <duration>6 35m</duration>
       </details>
    </flightevent>
    <flightevent>
       <flight>QR-0273</flight>
       <details>
          <destination>amsterdam</destination>
          <passengers>220</passengers>
          <duration>7h 40m</duration>
       </details>
    </flightevent>
    <flightevent>
       <flight>QR-1019</flight>
       <details>
          <destination>amsterdamn</destination>
          <passengers>210</passengers>
          <duration>7h 35m</duration>
       </details>
    </flightevent>
   </flights>

Save it is a preferred location (e.g., /Users/foo directory).

2. In the Streaming Integrator Tooling milestone pack, create and save the following Siddhi application.

   @App:name('ConvertXMLFormatApp')
   
   @App:description('Description of the plan')
   
   @source(type = 'file', file.uri = "file:/users/foo/flights.xml",
       @map(type = 'xml', enclosing.element = "/flights/flightevent", enclosing.element.as.event = "true",
           @attributes(flight = "flight", destination = "details/destination", passengers = "details/passengers", timeDuration = "details/duration")))
   define stream FlightInfoStream (flight string, destination string, passengers int, timeDuration string);
   
   @sink(type = 'file', file.uri = "file:/users/foo/formatttedflights.xml",
       @map(type = 'xml'))
   define stream FormattedFlightInfoStream (flight string, destination string, passengers int, timeDuration string);
   
   @info(name = 'Publish formatted events')
   from FlightInfoStream 
   select * 
   insert into FormattedFlightInfoStream;

3. Start the Siddhi application. An error log appears and it includes the "java.lang.NoClassDefFoundError" error. The complete error log is attached.
