Yes you do ;-)

Store your own Class in a seperate Java-File

Counter.java :

public class Counter
{
  private int count;    
                         
  public int Value()
  {
     return count;
  }                

  public void Raise()
  {
     count += 1;
  }

  public void Reset()
  {
     count = 0;
  }
}

Compile it an put it into the Classpath of your
Servlet-Engine. Then you can simply use it in

<xsp:page>

     <xsp:logic>

           Counter myCounter = new Counter ();
  
     </xsp:logic>

</xsp:page>

Hi,

I've solved the problem.
I looked at the compiled page in the repository directory. And I
discoverd that the functions are placed within an other class. So that
will never work because creating a variable in a class is one thing. But
you can't directly call a function on that class without doing that in a
function of the class itself. So I made a function around it:

    <xsp:logic>
      private static Counter myCounter = new Counter();

      public static int test() {
        myCounter.Raise();
        return myCounter.Value();
      } 
    </xsp:logic>

Now it all works fine :)

Peter

Hello,

hard to tell. Can you post the Parts of the xsp
where you encounter the Problem ?

I have tried that, and it works fine. Except if I really want to use the
counter...
If I do something like this: myCounter.Reset();

I get the following error message:


Error found handling the request.

  java.lang.Exception: XSP Java Compiler: Compilation failed for
