Thanks, that goes some way...but not all the way though. A common situation where a dynamic page displays 0....n items with different identifiers. For example, an item list is fetched from database, and page contains delete buttons for items 23, 67, 101 and 128. I do not think you can use this approach to solve that problem. You would have to magically create getDeleteItem23, getDeleteItem67....methods in your class.
How about this, Janne:
public final class ButtonCommand {
private ButtonCommand() {
} public final static String getCommand(HttpServletRequest request) {
Enumeration enum = request.getParameterNames();
String parameterName = null;
while(enum.hasMoreElements()) {
parameterName = (String)enum.nextElement();
if(parameterName.endsWith(".x")) {
return parameterName.substring(0,parameterName.indexOf('.'));
}
}
return parameterName;
}
}Now, you just dynamically make your name attribute of the <input type='image'> button, or the property attribute of your <html:image> button be whatever command you want on a dynamic or static basis. You can deal with the logic of what to do with your commands:
String command = ButtonCommand.getCommand(request);
anyway you see fit. I don't use buttons with indexed (0, 1, 2, ... , n) values, so I don't need to worry about that. That is easy to do, of course.

Cool, eh?
