Forms 9i FRM-40738 Hyperlink Bean problem

Question

Hello,
I've this error coming please help me.
I needed to see, how a bean is integerated in Forms 9i. I was
searching through the example at metalink and it gave me a
paper
"How to Integerate HyplerLink Bean in forms 9i", what steps
i followed are given in that paper.
Now when i run the form, it gaves me the error
FRM-40738 Argument to Built in SET_CUSTOM_PROPERTY CANNOT BE NULL.
the steps i followed are
1- I created a form called hyperlink.fmb
2- Then i created a ON LOGON trigger at this form
3- I opened the canvas and draw a Bean Area on it
4- Then i renamed that Item to Hyperlink by Property Plattelete
5- I named the canvas CONTROL
6- Then at module level i created a TRIGGER WHEN_NEW_FORM_INSTANCE and put following PL.SQL code in it
DECLARE
hHyperlink ITEM := FIND_ITEM('CONTROL.HYPERLINK');
BEGIN
FBEAN.Register_Bean( hHyperlink, 1, 'oracle.forms.demos.beans.Hyperlink');
FBean.Invoke( hHyperlink, 1, 'setURL', 'http://otn.oracle.com/products/forms');
FBean.Invoke( hHyperlink, 1, 'setLabel', 'Forms on OTN');
FBean.Enable_Event( hHyperlink, 1, 'actionListener', true );
END;
7-Then i created a Trigger at CONTROL.HYPERLINK, that was
WHEN_CUSTOM_ITEM_EVENT and put the following code in it
DECLARE
vcEventData varchar2(256);
BEGIN
vcEventData := Fbean.Invoke_Char('CONTROL.HYPERLINK', 1, 'getURL');
WEB.SHOW_DOCUMENT(vcEventData, '_blank');
END;
Then did the following steps of the locating the bean by the
JAR method.
Method 1 - The JAR Method:
a. Locate the hyperlink.jar file located in D:\9iDS\forms90\demos\hyperlink\classes.
b. Move the hyperlink.jar file to 9iDS_HOME\forms90\java.
c. Find the formsweb.cfg file in 9iDS_HOME\forms90\server.
d. Add the following configuration section to the file:
[hyperlink]
archive_jini=f90all_jinit.jar,hyperlink.jar
width=675
height=480
separateFrame=false
splashScreen=no
lookAndFeel=oracle
colorScheme=blue
The archive_jini parameter pointing to hyperlink.jar is the most important part
of this configuration.
e. Now go into Form Builder and accomplish the following:
Edit->Preferences->Runtime Tab
Add the config parameter to your "Application Server URL". It should look
something like this:
http://machine.domain:port/forms90/f90servlet?config=hyperlink
Then i compiled it and ran it, Now it gives this error
FRM-40738 Argument 1 to built in SET_CUSTOM_PROPERTY cannot
be null.
P.S I have set the implementation class property but, still i don't know
whats the problem, and where i am making mistake, please help me.
Please any help will be appreaciated.
Sincerely
