Is it possible to use JAXP in Applet? Really urgeng.

Question

I need to get String output from a DOM Document using JAXP in Applet. I want the entire XML document in one string .I write the code as following,but it doesn't work. Would you help me to point out the mistake I made in it?
Any help would be appreciated,
Thanks.

try
DocumentBuilderFactory factory= DocumentBuilderFactory.newInstance();
DocumentBuilder db =factory.newDocumentBuilder();
Document m_dDoc = db.newDocument();
Element e1=m_dDoc.createElement("first");
Text tx;
tx=m_dDoc.createTextNode("hi");
e1.appendChild(tx);
m_dDoc.appendChild(e1);
DOMSource doms = new DOMSource(m_dDoc);
Writer out = new StringWriter();
StreamResult result = new StreamResult(out);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();//wrong
transformer.transform(doms,result);
str=result.toString();
catch(Exception e)
e.printStackTrace();
     public void paint(Graphics g)
          g.drawString(str, 50, 60 );
}

The problem is that using the transformer in an applet results in the exception:
The exception is as following:
org.apache.xml.utils.WrappedRuntimeException: Output method is xml could not loa

I am still unclear to the cause, when I create a copy of the output_xml.properties file and put it somewhere in your classpathe (I put mine in a jar that the applet loads) you get:
java.lang.ExceptionInInitializerError

Which leads me to some questions:
What is XMLEntities.res, and how do I get one?
Does anyone know which version of Xalan and JAXP comes with J2SE 1.4.1?
Why the package "org.apache.xalan.Version" is not in the J2SE 1.4.1 release (and should it be?)
