[org.xml.sax.SAXParseException: Content is not allowed in prolog.]

[Former Member]

Hi,

I am using Version 12.1.5 Build(77)

My scenario is XML payload messages are received at XMIIlistener and i am able to use the Query action block read the message received. After that when i use the repeater and Read message action block to read the message payload (using messageId ) i am getting the following error

ERROR] Error found trying to execute action 'Read_Message_0' Exception: [Content is not allowed in prolog.]

[WARN] [Read_Message_0] Skipping execution of output links due to action failure.

[ERROR] [Read_Message_0] Action: Runtime threw an exception. Exception: [org.xml.sax.SAXParseException: Content is not allowed in prolog.]

[DEBUG] [Read_Message_0]: Finished[ <1 ms] Succeeded: false

I have validated the XML document payment with the Eclipse . The payload seems to be perfectly alright. But i am still getting the following error.

Any tips / suggestions please.

Thanks

For some reason when i use the Http post

under document to post, the message is not getting inserted into the JCOmessages table .

When Read query action runs it try to read the empty string and hence it was throwing this error

I used SOAPUp to post the xml document to resolve this issue

Hi,

please check if there is any character at the beginning of the XML. Maybe you have to use a Hex-Editor. The error seems to be caused if there are characters before the "<?xml" tag of a xml document. There may be [Byte Order Marks|http://en.wikipedia.org/wiki/Byte_Order_Mark] for example.

If you use

<?xml version="1.0" encoding="utf-8"?>

you may also try to omit the UTF and check if it works (see following [discussion|http://stackoverflow.com/questions/649209/content-not-allowed-in-prolog-exception]).
