[jbossws-issues] [JBoss JIRA] Commented: (JBWS-3095) WRONG_DOCUMENT_ERR when accessing SOAPMessage DOM using WebServiceProvider and Provider<SOAPMessage>

[Ray Cardillo (JIRA)]

    [ https://jira.jboss.org/browse/JBWS-3095?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12543422#action_12543422 ] 

Ray Cardillo commented on JBWS-3095:
------------------------------------

FYI, after much experimentation, a workaround is to copy the message.  I tried this after seeing other (older) reports that something in DOMUtils was causing similar problems in the past because it uses a Thread local variable to keep tract of the Document instance (or something like that).  So presumably copying the entire incoming SOAPMessage Document and then using the resulting Nodes puts everything in the right context (as opposed to trying to use the Nodes from the incoming Document directly).  This is not a satisfying solution because it requires us to copy every incoming message, and some can be large, but it does seem to be a functional workaround otherwise.

> While converting some code from JBossWS-Metro to JBossWS-Native, we have been working through a bug that seems to be related to XML parsing inconsistencies due to the different DOM implementations that are used by the two technologies.  We have a web service that is using the @WebServiceProvider feature of JAX-WS to create a custom Provider<SOAPMessage> so we can parse the XML directly.  However, any time we try to extract the XML, in any number of ways, it causes an internal "expandToDOM" to be called that ends up failing due to a WRONG_DOCUMENT_ERR.  At first we thought we were doing something incorrectly, but after careful analysis, and experimenting with many different ways of getting elements from the incoming SOAPMessage, we see this same stack trace in each case.  So it looks like there is a bug in the internal expansion.
