Hi,

I've created a simple processor in Apache Camel to wrap files as a Binary resource. It works fine if I convert to JSON but the XML version fails 

Binary binaryDoc = new Binary();

// should really make this a little more flexible and get the correct mime type.

binaryDoc.setContentType("application/rtf");

binaryDoc.setContent(payload);

exchange.getIn().setHeader(Exchange.CONTENT_TYPE,"application/xml+fhir");

exchange.getIn().setHeader(Exchange.HTTP_QUERY, "_id="+exchange.getIn().getHeader(Exchange.FILE_NAME, String.class)); //+exchange.getIn().

exchange.getIn().setBody(ctx.newXmlParser().encodeResourceToString(binaryDoc));

                final FhirContext ctx = FhirContext.forDstu2();

byte[] payload = exchange.getIn().getBody(byte[].class);

Binary binaryDoc = new Binary();

binaryDoc.setContentType("application/rtf");

binaryDoc.setContent(payload);

exchange.getIn().setHeader(Exchange.CONTENT_TYPE,"application/xml+fhir");

exchange.getIn().setHeader(Exchange.HTTP_QUERY, "_id="+exchange.getIn().getHeader(Exchange.FILE_NAME, String.class)); //+exchange.getIn().

exchange.getIn().setBody(ctx.newXmlParser().encodeResourceToString(binaryDoc));

Butter fingers caused the first entry to get posted. 

Changing the last line to exchange.getIn().setBody(ctx.newJsonParser().encodeResourceToString(binaryDoc)) works fine. When using XML (need to use XML due to limitations down the line) I get 

the following in the stack. Believe something similar has been found in the android implementation.

Hi Kevin,

That error typically means that Java isn't finding any StAX implementation on the classpath. Do you have the woodstox JAR included in your project?

Cheers,

James

Probably not, been having a 'bundle' of issues.

I've worked around the issue at the moment but will revisit.

Many thanks

Kevin
