NAMESPACE_ERR on invoking SOAPBodyImpl SOAPBodyElement addDocument(Document doc) with a document composed of ElementImpl nodes. ------------------------------------------------------------------------------------------------------------------------------- Key: JBWS-1863 URL: http://jira.jboss.com/jira/browse/JBWS-1863 Project: JBoss Web Services Issue Type: Bug Security Level: Public (Everyone can see) Components: jbossws-jaxws Affects Versions: jbossws-1.2.1 Environment: Windows XP. Java version "1.5.0_10". JBossAS 5.0.0.2 Reporter: Eddie Waner When creating a SOAP response for a web service following the @WebServiceProvider pattern, documents that are composed of ElementImpl nodes rather than ElementNSImpl nodes cause Xerces to throw a NAMESPACE_ERR exception. JBoss WS assumes that nodes coming in on the document are ElementImplNS nodes. If a document composed of ElementImpl nodes is passed to SOAPBodyElement addDocument(Document doc) the qualified name ends up being null in the call to Xerces ElementNSImpl setName(String namespaceURI, String qname). Thus the name space error... See stack trace and detail below. I ran into this problem using the Castor framework. This framework only creates ElementImpl nodes. I also reproduced the problem with simple cases. See below. Details: SOAPBodyImpl SOAPBodyElement addDocument(Document doc) creates a soapFactory and begins the copy of elements from the document into the soapBody with the default as deep through soapFactory.createElement(rootElement). In SOAPFactoryImpl createElement(Element domElement, boolean deep) an assumption is made that the element passed in is an ElementNSImpl (has a localName). SOAPFactoryImpl ... public SOAPElement createElement(Element domElement, boolean deep) throws SOAPException { if (domElement == null) throw new IllegalArgumentException("Source node cannot be null"); if (domElement instanceof SOAPElement) return (SOAPElement)domElement; String localName = domElement.getLocalName(); String prefix = domElement.getPrefix() != null ? domElement.getPrefix() : ""; String nsURI = domElement.getNamespaceURI() != null ? domElement.getNamespaceURI() : ""; ... In the case of an ElementImpl the localName is null as well as the prefix, ElementImpl will have the field name set. Thus when DOMUtils createElement(String localPart, String prefix, String url) is called the localPart == null but the prefix is an empty string. DOMUtils ... public static Element createElement(String localPart, String prefix, String uri) { Document doc = getOwnerDocument(); if (prefix == null || prefix.length() == 0) { log.trace("createElement {" + uri + "}" + localPart); return doc.createElementNS(uri, localPart); } else { log.trace("createElement {" + uri + "}" + prefix + ":" + localPart); return doc.createElementNS(uri, prefix + ":" + localPart); } } ... So the call into Xerces for createElementNS fails on setName(String namespaceURI, String qname) in ElementNSImpl as noted in the comment in the Xerces code: //NAMESPACE_ERR: //1. if the qualified name is 'null' it is malformed. //2. or if the qualifiedName is null and the namespaceURI is different from null, // We dont need to check for namespaceURI != null, if qualified name is null throw DOMException. ElementNSImpl.java private void setName(String namespaceURI, String qname) { String prefix; // DOM Level 3: namespace URI is never empty string. this.namespaceURI = namespaceURI; if (namespaceURI != null) { //convert the empty string to 'null' this.namespaceURI = (namespaceURI.length() == 0) ? null : namespaceURI; } int colon1, colon2 ; //NAMESPACE_ERR: //1. if the qualified name is 'null' it is malformed. //2. or if the qualifiedName is null and the namespaceURI is different from null, // We dont need to check for namespaceURI != null, if qualified name is null throw DOMException. if(qname == null){ String msg = DOMMessageFormatter.formatMessage( DOMMessageFormatter.DOM_DOMAIN, "NAMESPACE_ERR", null); throw new DOMException(DOMException.NAMESPACE_ERR, msg); } Stack Trace:
