Java Bean does not display in Forms 9i

Question

Hi,
I created a Java bean taht would not display in a Forms 9i application. I do not get any error messages, just nothing seem to happen. I did the following:
1. Created a Java Bean with az Init() public function, packed it into a jar file and put it into <9iASHome>\forms90\java
2. Added the jar file to the formsweb.cfg file's archive_jini.
3. Created a Form with a Java Bean item on a canvas.
4. Set the implementation property of the bean item to the full java 'direcotry' path of the class.
5. Created the WHEN-NEW-FORM-INSTANCE trigger and put this code into it:
fbean.register_bean('BLOCK3.BEAN_AREA4',1,'geoifsweb.ifsframe');
After deploying the form to 9iAS and running it nothing seems to happen, only the place of the Java Bean appears on the Form. Teh Java Bean class extend a JFrame class, so I would expect it to appear on the screen.
What am I missing? Thank you for any help or hint in advance.

When using fbean.register_bean you don't need to set the implementation class of the bean at design time.
You must however supply the full package and class name in the register_bean call.
Do you get any exceptions in the Java console?
I'd also switch logging on (see FBEAN.Set_Logging_Mode)
