Problem with DispatchPtr

Hi,

The main method of the sample code in the package is

public static void main(String[] args) {
   try {
 DispatchPtr app = new DispatchPtr("Word.Application");
 app.put("Visible", true);}
   catch (Exception e) {
      e.printStackTrace();}
}

and the code works well.  Within my project I need to invoke the COM-object
methods WITHOUT a DispatchPtr.  Therefore I tried the following:

public static void main(String[] args) {
   try {
 _Application app = new _Application();
 app.HelpTool();}
   catch (Exception e) {
      e.printStackTrace();}
}

which should be okay because the class _Application was generated by Jawin.
 The method HelpTool() is defined in _Application.  The debugger told me
that the new object app has been created, but once app.HelpTool() is being
compiled, there occurs this error:

compile:
org.jawin.COMException: 8000ffff: NULL GIT peer
    at org.jawin.marshal.GenericStub.dispatchInvoke0(Native Method)
    at org.jawin.marshal.GenericStub.dispatchInvoke(GenericStub.java:84)
    at org.jawin.DispatchPtr.invokeN(DispatchPtr.java:473)
    at org.jawin.DispatchPtr.invokeN(DispatchPtr.java:433)
    at com.jawin.demo.doc._Application.HelpTool(_Application.java:1479)
    at com.jawin.demo.main.Main.main(Main.java:41)
debug:
BUILD SUCCESSFUL (total time: 17 seconds)

So my question is this:  Is there a way to implement this without a
DispatchPtr, and if yes, how??

Thanks,
Tobias
