org.xml.sax.SAXParseException: The root element is required in a well-formed document

[mskendrick]

I'm getting the following error on WebSphere 6.1 running Spring WS RC2:

Here is my SOAP message request:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns="urn:ListCodeValues/1.0">
   <soapenv:Header/>
   <soapenv:Body>
      <ns:ListCodeValuesRequest>
         <ns:UserId>skendr</ns:UserId>
         <ns:Password>tester78</ns:Password>
         <ns:CodeCategory>BU</ns:CodeCategory>
      </ns:ListCodeValuesRequest>
   </soapenv:Body>
</soapenv:Envelope>

Any ideas?
Thanks in advance,
Shannon Kendrick

I have no idea. Is this the first time you've deployed to WebSphere, or did you try it before (using RC1 or earlier) successfully?

I have the same problem in WAS 6.0.2.15, seems to me that it is due to the saaj implementation of WAS. Is there another way of parsing the soap message instead of saaj?

btw, isn't WAS 6.1 java 5 ? You can then run the sun saaaj impl (that is also used in the examples) and use the PARENT_LAST loader to ensure that it is loaded before the ibm implementation..

Anyone else succesfully running this on WAS

I have found the problem:

Axis1 (and I believe this is what the core saaj implementation of websphere is based on) caches the InputStream for later use.

When calling the MessageFactory.createMessage(mimeHeaders,InputStre am) the implementation of Axis1 (and websphere) caches the inputstream.

In AbstractWebServiceConnection.receive however, the inputstream is closed after creating the message. Causing Axis to lose the message contents and thus a SAXParseException later on in the process

I have implemented my own version of the MessageFacroryImpl that convert the inputstream to a byte[].. Hopefully this problem can be solved within Spring-WS.. Maybe not closing the InputStream?

Hope this helps

I've created SWS-150, which will be fixed for 1.0.

Thanks for the investigation!

[Arjen Poutsma]

It's fixed. Unfortunately, I could not reproduce it, but at least the ServletInputStream is not closed anymore in AbstractWebServiceConnection.receive().

Could you try one of the nighly builds starting tomorrow and see whether it works?

On websphere 6.1.0.9, we are getting this error:

Is this caused by the same reason as the above posts, if so, how can we get a copy of the nighly build of 1.0.1-SNAPSHOT. We can't get it from the Spring site.

This is just saying that the server couldn't parse the XML - there may in fact be nothing wrong with the XML at all. Check your server logs rather than the client ones, I've often found the problem being due to missing jar files on the server.

[java123]

Thanks for all of your responses. We changed to use Spring-ws 1.0.0 which fixed the problem.
