I will need a bit more guidance on how to set the value of the field to "new
Packages.java.util.Date()". As there appears to be a few locations that
relate to saving the form and I have only little Java experience. My binding
file is:
---
cocoon.load("resource://org/apache/cocoon/forms/flow/javascript/Form.js");
function form2xml(form) {
var documentURI = cocoon.parameters["documentURI"];
var document = loadDocument(documentURI);
form.load(document);
form.showForm("form-display-pipeline");
form.
form.save(document);
saveDocument(document, documentURI);
cocoon.sendPage("form-success-pipeline");
}
function loadDocument(uri) {
var parser = null;
var source = null;
var resolver = null;
try {
parser =
cocoon.getComponent(Packages.org.apache.excalibur.xml.dom.DOMParser.ROLE);
resolver =
cocoon.getComponent(Packages.org.apache.cocoon.environment.SourceResolver.RO
LE);
source = resolver.resolveURI(uri);
var is = new
Packages.org.xml.sax.InputSource(source.getInputStream());
is.setSystemId(source.getURI());
return parser.parseDocument(is);
} finally {
if (source != null)
resolver.release(source);
cocoon.releaseComponent(parser);
cocoon.releaseComponent(resolver);
}
}
function saveDocument(document, uri) {
var source = null;
var resolver = null;
var outputStream = null;
try {
resolver =
cocoon.getComponent(Packages.org.apache.cocoon.environment.SourceResolver.RO
LE);
source = resolver.resolveURI(uri);
var tf =
Packages.javax.xml.transform.TransformerFactory.newInstance();
if (source instanceof
Packages.org.apache.excalibur.source.ModifiableSource
&&
tf.getFeature(Packages.javax.xml.transform.sax.SAXTransformerFactory.FEATURE
)) {
outputStream = source.getOutputStream();
var transformerHandler = tf.newTransformerHandler();
var transformer = transformerHandler.getTransformer();
transformer.setOutputProperty(Packages.javax.xml.transform.OutputKeys.INDENT
, "true");
transformer.setOutputProperty(Packages.javax.xml.transform.OutputKeys.METHOD
, "xml");
transformerHandler.setResult(new
Packages.javax.xml.transform.stream.StreamResult(outputStream));
var streamer = new
Packages.org.apache.cocoon.xml.dom.DOMStreamer(transformerHandler);
streamer.stream(document);
} else {
throw new Packages.org.apache.cocoon.ProcessingException("Cannot
write to source " + uri);
}
} finally {
if (source != null)
resolver.release(source);
cocoon.releaseComponent(resolver);
if (outputStream != null) {
try {
outputStream.flush();
outputStream.close();
} catch (error) {
cocoon.log.error("Could not flush/close outputstream: " +
error);
}
}
}
}

I guess you mean CForms?

Don't use XSP at all. Add a fd:output with datatype date to your form
definition, but not into the template. Immediately before saving the
form set the value of the field to "new Packages.java.util.Date()".
