It looks like you might be trying to set-up a SOAP method using SOAP RPC or SOAP document-style encoding. That is, the input is an XML tree in String form. If that's true then the output should also be a String, even if it contains an XML tree. Most XML libraries give you a method to output an XML tree as a String. For example, in JDOM you would use:
DOMOutputter do = new DOMOutputter() String myxmltree = do.output( element ) Hope this helps. -Frank -- Frank Cohen, Founder, http://www.PushToTest.com, phone: 408 374 7426 PushToTest offers free open-source test software and global services solutions that test, monitor and automate Web Service systems for functionality, scalability and performance. > From: "Ghershony, Arie" <[EMAIL PROTECTED]> > Reply-To: [EMAIL PROTECTED] > Date: Tue, 11 Feb 2003 15:13:46 -0500 > To: "'[EMAIL PROTECTED]'" <[EMAIL PROTECTED]> > Subject: return value as an XML document > > Hi, > Can any one tell me why do I receive the following error while compling:" > Incompatible types found: > org.w3c.dom.Element > required: java.lang.String > return result > ^ > > 1 error. > > This is the relevant code: > > import org.apache.axis.client.Call; > import org.apache.axis.client.Service; > import org.apache.axis.message.SOAPEnvelope; > import org.apache.axis.message.SOAPBodyElement; > import org.apache.axis.utils.XMLUtils; > > import org.w3c.dom.Document; > import org.w3c.dom.Element; > import org.w3c.dom.Node; > import org.w3c.dom.NodeList; > > ... some code here > > it works when I am using command line argument: > public static void main(String [] args) throws Exception { > > but not if I pass a String array to a function: > > public String getBattleService(String[] uniqb) throws Exception { > > DocumentBuilderFactory documentBuilderFactory = null; > DocumentBuilder parser = null; > > // We need a namespace-aware parser > documentBuilderFactory = DocumentBuilderFactory.newInstance(); > documentBuilderFactory.setNamespaceAware(true); > parser = documentBuilderFactory.newDocumentBuilder(); > > // We create the document for the request (the XML document that will > // be embedded inside the SOAP body). > Document document = parser.newDocument(); > Element element = document.getDocumentElement(); > > // The <portfolio/> element is the root of our document; > Element requestElement = document.createElementNS(nameSpaceURI, > orderbattleTag); > // Element command = document.createElement(args[0]); > Element command = document.createElement(uniqb[0]); > requestElement.appendChild(command); > > // We add the list of ticker symbols > for(int index = 1; index < uniqb.length; index++) { > Element ticker = document.createElement(tickerTag); > > // ticker.appendChild(document.createTextNode(args[index])); > ticker.appendChild(document.createTextNode(uniqb[index])); > command.appendChild(ticker); > } > > // Unless the command is a get, we add the get command > if(!uniqb.equals(getCommand)) { > requestElement.appendChild(document.createElement(getCommand)); > } > > Element result = null; > boolean local = false; // set to true for local test (inproc) > > if(local) { > // Local test, no SOAP > result = orderbattle(requestElement, > (Element)requestElement.cloneNode(true)); > } else { > // We create a SOAP request to submit the XML document to the > > // server.
