xml document always null?
hi all,
i'm trying to create an xml document but all i get for output is
el.toString = [foo: null]
el.getNodeValue = null
can anyone see what i'm doing wrong?
[code]
import javax.xml.parsers.DocumentBuilder;
import org.apache.soap.util.xml.XMLParserUtils;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
public class XmlTest {
public static void main(String[] args) {
DocumentBuilder db = XMLParserUtils.getXMLDocBuilder();
Document doc = db.newDocument();
Element el = doc.createElement("foo");
el.appendChild( doc.createTextNode("bar") );
System.out.println("el.toString = " + el.toString());
System.out.println("el.getNodeValue = " +
el.getNodeValue());
}
}
[/code]

thanks scott. The DataHandler i am using contains an xml file, a way around using DataHandlers is to put the XML file into a string which can be done using JDOMs XMLOutputter.

Brian.

The whole notion of passing an attachment as a parameter is not universally supported, either. Nor is the WSDL representation of a message with attachments (http://www.w3.org/TR/wsdl#_Toc492291084).
My knowledge of Sun's support for attachments is incomplete. The SAAJ API is what I am familiar with. It is designed to allow you to create and examine SOAP messages that include attachments. Clients using SAAJ build and dissect messages at a low-level and use SOAPConnection for transport. I do not see any way to use JAX-RPC APIs, e.g. javax.xml.rpc.Call provides no access to attachments. As such, I doubt you can expect Sun's code to consume WSDL for a call with an attachment, even if the WSDL includes a MIME description and the attachment is not also a parameter.
So, with JWSDP, I think you are left to use SAAJ to interact with your service.

Subject: namespace errors
Hi All,
I have created a webservice using apache soap. One of the service methods accepts a DataHandler object from the javax.activation package. This appears in the WSDL file as a DataHandler from the http://xml.apache.org/xml-soap This is giving a "model error" when stubs are created from a JWSDP client! Does anyone know why?
Thanks,
Brian.

Apache SOAP includes a class to help serialize a Node. In org.apache.soap.util.xml.DOM2Writer, there is a method
public static String nodeToString(Node node)
to get stringized XML. There is also
public static void serializeAsXML(Node node, Writer writer)
to output to any Writer. I would be interested to hear what you get from nodeToString(doc).

Test it :
el.setNodeValue( "bar");
