Description

Hi,

We have created a simple camel route -

@Override@Override public void configure() throws Exception { from("file://C:/in/?fileName=Input_UTF8.txt") .process(exchange ->

{           System.out.println("Headers after in: "+ exchange.getIn().getHeaders());     }

)         .onCompletion()           .process(exchange -> {                 sendFooter(exchange);                 System.out.println("Headers after Footer: "+ exchange.getIn().getHeaders());           })                   .end()                      .process(exchange -> {  sendHeader(exchange);  System.out.println("Headers after header: "+ exchange.getIn().getHeaders());        }) .split(body().tokenize(lineSeperator)) .streaming()   .to("file://C:/out/?fileName=Output.txt&fileExist=Append") .process(exchange -> {           System.out.println("Headers after each record: "+ exchange.getIn().getHeaders());     }); } private void sendHeader(Exchange exchange) { ProducerTemplate template = getContext().createProducerTemplate(); template.sendBodyAndHeaders("file://C:/out/?fileName=Output.txt&fileExist=Append","header1,header2",exchange.getIn().getHeaders());    } private void sendFooter(Exchange exchange) { ProducerTemplate template = getContext().createProducerTemplate();               template.sendBodyAndHeaders("file://C:/out/?fileName=Output.txt&fileExist=Append","footer",exchange.getIn().getHeaders()); }

 

CamelFileNameProduced header is not coming when there is no data in the file (header and footer will be there) although it is creating a file in the destination directory.
