[jdom-interest] JDOM w/ Apache Axis

[Jerry Jalenak]

Greetings All!

I'm fairly new to using JDOM to generate XML, so bear with me.  I'm in the
processing of writing a web service using Apache Axis.  As part of my
'learning' process, I've been able to have a dotNet client hit my web
service and retrieve a basic String, a basic JavaBean, and an Array object
from the JavaBean.  I'm now trying to generate a XML document using JDOM,
and pass it back to the client.  Here's my basic 'HelloWorld'
implementation:

package ws;

import org.jdom.Element;

/**
 * @author jjalenak
 *
 */
public class HelloWorldImpl implements HelloWorld
{
	/* (non-Javadoc)
	 * @see ws.HelloWorld#hello()
	 */
	public Document hello() throws Exception
	{
		Document _d = new Document();
		
			Element _e = new Element("root");
			_e.setText("Hi There!");

		_d.setRootElement(_e);
		return _d;
	}

	/* (non-Javadoc)
	 * @see ws.HelloWorld#goodbye()
	 */
	public Document goodbye() throws Exception
	{
		Document _d = new Document();
		
			Element _e = new Element("root");
			_e.setText("Good Bye!");

		_d.setRootElement(_e);
		return _d;
	}
}

When I ran the WSDL2JAVA emitter, it created a 'Document' bean in my 'ws'
package, and removed the import for the org.jdom.Document.  The web service
deploys on Tomcat (5.0.18) without any problems.  When I try to call the web
service from my test Java web app, I get the following exception:

exception is (500)Internal Server Error
AxisFault
 faultCode: {http://xml.apache.org/axis/}HTTP
 faultSubcode: 
 faultString: (500)Internal Server Error
 faultActor: 
 faultNode: 
 faultDetail: 
	{}string: return code:  500

Digging into this, I found what I think is the 'true' problem :
java.io.IOException: No serializer found for class org.jdom.Element in
registry org.apache.axis.encoding.TypeMappingImpl at 6c2308.  It appears that
although WSDL2JAVA converted the Document object to a proper bean, it didn't
do the Element object.  I not quite sure where to go from here, so if anyone
has some guidance, I'd sure appreciate it.  Better yet, if someone has a
working example of an Axis-based webservice using JDOM that they can share,
I'd also appreciate being able to get a look at it.

Thanks!
