do classes have properties

Posted: Jun 14, 2002 1:52 PM

I've tried to create a method in my applet that will return the current system time ....

public Long getUsersSystemTime()
{
Long l = new Long( new java.util.Date().getTime() );
return l;
}

... but when my javascript calls it, it gets an object doesn't support this method or property error. I've combed through my java and html code and I can't find any reason why it wouldn't work. So, my only other option I can think of is to have a property in my applet that my javascript can read. I know in C# you can do a get set property block. Is there anything like that in Java that I could do? Thanks.

I don't understand exactly what you mean by having your javascript call your java code. The JSP or Servlet that is writing the page could just put the time somewhere. If you want it more dynamic, javascript can get the time itself by instantiating a Date object, like so:

   var currentTime = new Date();
   document.write( "The current time is " + currentTime );

If you want it to be kept up to date, you could keep updating a form element. Maybe I don't understand what you are trying to do...
