Xalan Extensions


I have problems with my first extension for Xalan-Java 1

I wrote a simple java class that uses the SimpleDateFormat-class. It has
only one method that returns the formated date as a String.

My XSL-stylesheet should just call the method and return it  in a
xsl:variable. I looked at the examples on the xalan home page, but I just
don't get it. Where do I create an instance of my class? How do I call a
method?

Thanks for any help!

  public String getFinnishDate()
  {
    Date now = new Date();
    String finnishDate = finnishFormat.format(now);
    return finnishDate;
  }

You should really upgrade to XalanJ2.  XalanJ1 is going away.

Use the java: prefix on your xsl:value-of element.  You do not have
date: namespace prefix defined.  Your .new call created a new instance
of the class.
