Dynamic cast at runtime (Here we go again! )

Question

Hy folks,
today I read so many entries about dynamic casting. But no one maps to my problem. For a lot of them individual alternatives were found. And so I hope...
Ok, what's my problem?
here simplified:
I have a HashMap with couples of SwingComponents and StringArray[3].
The SwingComponents are stored as Objects (they are all JComponents).
The StringArray comprised "the exact ClassName" (like "JButton" or "JPanel"),
"the method, who would be called" (like "addItemListener")
and "the ListenerName" (like "MouseMotionListener" or "ActionListener")
At compiletime I don't know, what JCommponent gets which Listener.
So a JPanel could add an ItemListener, another JPanel could add
a MouseListener and an ActionListener.
I get the description of the GUI not until runtime.
The 'instanceof'-resolution is not acceptable, because there are above 50 listener. If I write such a class, I would write weeks for it, and it will be enormous.
Now, my question
I get the class of the Listenertype by
Class c=Class.forName(stringArray[2]);
and the method I'll call
java.lang.reflect.Method method=component.getClass().getDeclaredMethod(s[1],classArrayOfTheParameter[]); //the parameter is not important here
And I have a class, who implements all required ListenerInterfaces: EHP
Now I wish something like this
method.invoke((JPanel)jcomponent,(c)EHP);
Is there anybode, who can give me an alternative resolution
without instanceof or switch-case ?

I see, your right. Thanks. This problem is been solved.
But a second problem is, that jcomponent can be every Swing-Object.
I get the swing-component as Object from the HashMap . And I know
what it is exactly by a String.
What I need here is
method.invoke(("SwingType")swingcomponentObject,Object[] args);
I know, that this doesn't exist. Here my next question
Can I take an other structure than HashMap, where the return value
is a safety type (and not an Object). Or there are some other hints
about similar problems and there resolutions?
I don't like to write 50 (or even more than 50) "instanceOf"-instructions or "equal"-queries. And I'm not really interested in the whole set of java swing elements existing.
I appreciate all the help I can get.
