There are people that find the instantiation and startup of Java to take too long so they serialize the whole instantiated GUI and then write that to a binairy blob to the jar file. The client then starts the GUi by deserialising that file and showing it. I think its butt-ugly and feel it does not need to be supported, but there are people out there (mostly companies) that do it. So, now you know :) -- Thomas Zander pgpRuMJXzuoMs.pgp Description: PGP signature ___ Classpath mailing list Classpath@gnu.org http://lists.gnu.org/mailman/listinfo/classpath
pre-GCJ4 support
Hi,
what is the status of the discussion of pre-GCJ4 support in GNU
Classpath. Should we still support GCJ3.4 ('s bugs)? I would vote for
switching to GCJ4 so that accessibility support in Swing can be implemented.
FYI: I've tried to build the current GNU Classpath with both GCJ3.3 and
GCJ3.4 and it fails with 120 errors in the CORBA stuff where jikes
doesn't complain. Don't know if CORBA is important in these respects...

An Eclispe style for GNU
Here is my attempt at expressing the GNU Java formatting style in Eclipse. This is tested in Eclipse 3.1M7. Perhaps we can develop this into a standard GNU/Classpath format - and perhaps have it shipped with Eclipse. I'm not endorsing this as my *preferred* formatting style, but as a modest encoding and fine-tuning of existing styles. (I still mostly use Emacs.) -- --Per Bothner [EMAIL PROTECTED] http://per.bothner.com/ ___ Classpath mailing list Classpath@gnu.org http://lists.gnu.org/mailman/listinfo/classpath

Hi Per, GNU Classpath already ships with an GNU style for Eclipse: scripts/eclipse-gnu.xml. The Eclipse packaged in Fedora Core 4 is bundled with this style. I think it's also been submitted upstream to the Eclipse project, but I don't know any more than that. AG ___ Classpath mailing list Classpath@gnu.org http://lists.gnu.org/mailman/listinfo/classpath
XML strictness
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi.
I got a bug report about our DOM parser which I thought to be valid but
then found something that irritates me.
The following program (probably) demonstrates a problem with Classpath'
DOM parser.
package xmlfilter;
!various imports ommitted!
public class XMLFilter {
public XMLFilter() {
super();
}
public static void main(String[] args) throws Exception {
/*
* parses stdin
*/
Document doc =
DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(System.in);
Element newElement = doc.createElement("new");
// The next line makes it unhappy ...
doc.appendChild(newElement);
/*
* serializes xml file to System.out
*/
TransformerFactory tfactory = TransformerFactory.newInstance();
Transformer serializer = tfactory.newTransformer();
doc.normalize();
serializer.setOutputProperty(OutputKeys.INDENT, "yes");
serializer.setOutputProperty(OutputKeys.ENCODING, "iso-8859-1");
serializer.transform(new DOMSource(doc),
new StreamResult(System.out));
}
}
When run as 'echo "" | jamvm -cp . xmlfilter.XMLFilter' you get the
following exception:
gnu.xml.dom.DomDOMException: The node doesn't belong here.
More Information: document element already present:
gnu.xml.dom.DomElement[a]
Node Name: new
at gnu.xml.dom.DomDocument.checkNewChild (DomDocument.java:294)
at gnu.xml.dom.DomDocument.appendChild (DomDocument.java:317)
at xmlfilter.XMLFilter.main (XMLFilter.java:42)
You get the same message with all proprietary JDKs prior to 1.5 . The
latest incarnation however accepts creating the node and generates
the following XML upon calling 'echo "" |
/opt/sun-jdk-1.5.0/bin/java xmlfilter.XMLFilter':
AFAIK there should/must be only one top-level node which is named .
I am confused ...
Is Sun breaking the rules here?

The "XQuery 1.0 and XPath 2.0 Data Model" is a bit more general: See http://www.w3.org/TR/xpath-datamodel/#DocumentNode Of course an *XML document* is somewhat more restricted, but if you want to use DOM to support XQuery/XPath/XSLT objects it makes sense to allow more generality. -- --Per Bothner [EMAIL PROTECTED] http://per.bothner.com/ ___ Classpath mailing list Classpath@gnu.org http://lists.gnu.org/mailman/listinfo/classpath
