problem in aggregation

[vasukfuse <va...@gmail.com>]

Hi All

i have to aggregate two XML files which are available at different 
times.but i am getting error in out put file.

here i am providing my code error details

 public void configure() {
				  try {
				            DataFormat bindy = new
BindyCsvDataFormat("com.softedge.dto");
				            DataFormat bindy1 = new
BindyCsvDataFormat("com.softedge.dto");
				                  from("file://TEST?fileName=order.csv&noop=true").
				                  unmarshal(bindy).
				                  marshal().
				                  xstream().
				                  to("file://TESTOUT?fileName=order.xml");
				                  from("file://TEST?fileName=order_line.csv&noop=true").
				                  unmarshal(bindy1).
				                  marshal().
				                  xstream().
				                  to("file://TESTOUT?fileName=orderLine.xml");
				                  Thread.sleep(1000);
				                  from("file://TESTOUT?idempotent=true")
				                  .aggregate(body(),new MyAggregationStrategy())
				                      .completionTimeout(30000)
				                     // .batchSize(2)
				                  .to("file://TESTOUTA?fileName=aggregate.xml");
				                 



the out put file should contain the data from Order.xml, OrderLine.xml 

but the output file aggregate.xml  contains only orderline out put and it is
showing the error 

"Only one top level element is allowed in an XML document. Error processing
resource"

pls help me out

Hi,
Can you add some debug statements to your aggregator:

          newIn.setBody(oldBody + newBody); 

For example, what is oldBody and what is newBody?  Based on the error you
are receiving, you might be concatenating two XML documents like this:

<document1/>
<document2/>

This will not create a valid XML document because there will be two top
level elements.  You might try something like:

   newIn.setBody("<wrapper>" + oldBody + newBody + "</wrapper>");

Then you can strip the wrapper off in an XSLT or processor and combine the
two docs as they should be.

Thanks,
Yogesh
