Wing Yew Poon commented on XMLBEANS-266:
----------------------------------------

Wesley,
the normal channel for user questions and issues is the user mailing list \
(user@xmlbeans.apache.org). Bugs and enhancements may be filed in JIRA. When filing a \
bug in JIRA, it is helpful to attach repro data (xml schema/instance, java program) \
                as files (rather than in the text body).

> javax.xml.stream.XMLStreamException: problem accessing the parser
> -----------------------------------------------------------------
> 
> Key: XMLBEANS-266
> URL: http://issues.apache.org/jira/browse/XMLBEANS-266
> Project: XMLBeans
> Type: Bug

> Components: Binding
> Versions: Version 2.1
> Environment: Windows XP, Eclipse w/ MyEclipse plugin, Tomcat
> Reporter: Wesley King

> 
> I have an soap message receiver class that extends \
> AbstractInOutSyncMessageReceiver.  I use this class to handle my web service \
> requests.  Inside the invokeBusinessLogic(MessageContext, MessageContext) method, I \
> am attempting to parse the envelope header first and then the body.  The header \
> contains an element called MultiSpeakMsgHeader and the body contains an element \
> called PingURL.  All the XML objects were created using XMLBeans.  The web service \
> works fine if I only attempt to parse the body's first element creating the \
> PingURLDocument.  If I try to parse the header's first element creating the \
> MultiSpeakMsgHeaderDocument, that works fine, but right afterwards if I try to \
> parse the body's first element I get an exception: XMLStreamException: problem \
> accessing parser. Am I doing something wrong?  If so, any help would be \
> appreciated.  If not, is this a known bug/issue?  And is there a work around?  Also \
> I wasn't sure if this is the right place to submit questions.  What is the normal \
> procedure for submitting questions or possible bugs? Include below are three files \
> that may or may not be helpfull.  (1) The AbstractInOutSyncMessageReceiver java \
> file.  (2) The skeleton java file that handles the service.  And (3) the xml I'm \
> sending to the server.  As I mentioned above, everything works fine if I don't \
> attempt to read the header.  As a side note, the reason I need to read the header \
> is to check for a valid user id and password.  If there is another way to \
> check/validate header information, I'm open to suggestions. \
