Re: Payload: .No message body writer found for response class :
ArrayList.
Posted by Sergey Beryozkin <se...@iona.com>.
This is probably because the XML document is broken, you output multiple
fragments but the resulting doc has no root element.
So in your custom provider just write directly into the stream something
like
out.write("<files>")
// write individual files here
out.write("</files>")
Alternatively rather than doing it all yourself just return
List<JAXBElement> with JAXBElements being initialized from the files. In
this case You'll need to configure JAXBElementProvider to wrap the
collection.
Or just return a List<InputStream> rather than reading into XML and then
writing into output stream.

Re: Payload: .No message body writer found for response class :

Posted by Parimal Dhinoja <pd...@gmail.com>.
Hi,
As you see in following code, My requirement is to send one or more XML
files in response stream. I have done following to accomplish my
requirement:
1. Resource class method returns ArrayList which contains XML file objects.
2. I have created custom MessageBodyWriter, which modify the response, by
getting files from Arraylist and write it into Response Stream.
I am accessing my service from Browser with url :
http://localhost:443/application/service?x=fileDir
I have checked that I have got all the files in response body with 200Ok
code, but browser shows XML parsing error as shown below.
"XML Parsing Error: junk after document element"
so is it problem from CXF side or it is browser error? any idea? Please note
that if I send single xml file with same code, it returns successfully and
browser display that file properly. I guess that because there are multiple
files one after another, browser is not able to parsing it? is that true?
Please note, I need to send multiple files in response stream as it is third
party client requirement.
Regards,
Parimal
