Subject Cannot write null body to file - using ftp component
Date Fri, 02 Oct 2015 01:11:11 GMT
All,

I have the following code snippet and exception:

I have a route that has a jetty enpoint which accessed, starts a process
which builds an excel file and stores in in a 
directory.  The next component, file, should pick the file up and pass it to
the ftp component, transferring it to a remote server.

Everything seems to work up to the ftp component.  The .xls files are being
generated to in the X:\xxx\reports\finished\ directory.

Any assistance would be greatly appreciated!

*public class ReportRouteBuilder extends RouteBuilder {

	public void configure() throws Exception {

		final Endpoint jettyEndPoint = configureSslForJetty();
		
		from(jettyEndPoint)
				.process(new Processor() {

					@Override
					public void process(Exchange exchange) throws Exception {
						/*
						 * code to generate .xls document and store on the local file system
						 */
						.
                        .
                        .
						exchange.getOut().setHeader(Exchange.FILE_NAME, outputFileName);
						exchange.getOut().setHeader("status", table.getStatus());
						exchange.getOut().setHeader("CamelFileName",table.getFileName());
						exchange.getOut().setHeader("CamelFileNameOnly",table.getFileName());
						exchange.getOut().setHeader("CamelFileAbsolute","true");
					
exchange.getOut().setHeader("CamelFileAbsolute","X:\\xxx\\reports\\finished\\");
					
exchange.getOut().setHeader("CamelFilePath","X:\\xxx\\reports\\finished\\"+currentPivotTable.getFileName());
						exchange.getOut().setHeader("CamelFileParent","X:\\xxx\\reports\\");
    .
    .
    .
						}
				}).choice().when(header("status").isEqualTo("success")).
			
from("file:X:\\xxx\\reports\\finished?fileExist=Ignore&doneFileName=${file:name}.
				done&delete=true&maxMessagesPerPoll=1")
				to("ftp://ccc.xxx.1.2:21/?username=userx&password=abcd&binary=true")
				;

jettyComponent.createEndpoint("jetty:https://0.0.0.0:1111/exportXls");
