We are using the released version which has Attribute.getBooleanValue().
We use this method to get  the HTML radio button values.  We based our
design on the published javadocs and the published code.

Please do not remove existing functionality.

  JDOM ignores 0 & 1 now in the same way as "true" and "false".
getBooleanValue() was removed a *long* time ago.  You should update your
version of JDOM  :-)

    Hi. JDOM newbie here. :)

    I'm using JDOM in a servlet project and I was about to change all my
True/False type attributes in the XML to be 0 / 1 when I decided to peek at
the JDOM source to see just what kind of values were considered boolean. To
my surprise, 0 and 1 wasn't on the list. Was this an intention omission? It
seems to be a fairly common representation. I did a quick search through the
archives and didn't see anything on the topic.

    Loving JDOM so far!


    For convenience I've copied the source (beta6) below:

        public boolean getBooleanValue() throws DataConversionException {
            if ((value.equalsIgnoreCase("true")) ||
                (value.equalsIgnoreCase("on")) ||
                (value.equalsIgnoreCase("yes"))) {
                return true;
            } else if ((value.equalsIgnoreCase("false")) ||
                       (value.equalsIgnoreCase("off")) ||
                       (value.equalsIgnoreCase("no"))) {
                return false;
            } else {
                throw new DataConversionException(name, "boolean");
