-------------------------------------
I'm going to close this as it so old and the test case is pretty complicated.
> javax.xml.stream.XMLStreamException: problem accessing the parser
> -----------------------------------------------------------------
>
> Key: XMLBEANS-266
> URL: https://issues.apache.org/jira/browse/XMLBEANS-266
> Project: XMLBeans
> Issue Type: Bug
> Components: Binding
> Affects Versions: Version 2.1
> Environment: Windows XP, Eclipse w/ MyEclipse plugin, Tomcat
> Reporter: Wesley King
> Priority: Major
>
> 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.
