Oracle Forms

Hi,
I can't import java class in the form.
I have been reading through most of the forums and
I have followed the instruction and followed the sample form from OTN (http://otn.oracle.com/sample_code/products/forms/content.html the importing of security.jar, which is similar to what I am about to do)

Ok, this is what I did and tell me what I did wrong.

1. I need a security.jar that my co-worker wrote. So I copied the jar files into c:\project.
In it there are a bunch of jar files
(he uses jdk.1.4, I am not sure if this might cause the problem).

2. on the CLASSPATH in CONTROL PANEL -- System icon,
i have following:
c:\project\security.jar;c:\program files\java\jre1.4.0_01\bin;C:\oracle\orads9i\jlib\bigraphbean.jar;C:\oracle\orads9i\jlib\LW_PfjBean.jar;C:\oracle\orads9i\jlib\bigraphbean-nls.zip

BTW, my form version is 9.0.2.11.0, in windows environment.


thank you soo much for your help.

3. then I launched the forms, and tried to import java classes, it took about 2 minutes to pop up the window and it gives me an error:
PDE-PER001 Internal error (depjv1).

4. then I closed it and tried to import java classes again, and this second time didn't give me any error, but it gives me a blank selection.

Can anyone tell me what I did wrong? please?
and also can anyone tell me what's the different between the CLASSPATH in control panel and in regedit, under ORACLE, i also have a classpath set.
This is what I have set under my oracle registry.
c:\program files\java\j2re1.4.0_01;c:\project\security.jar;C:\oracle\orads9i\jlib\bigraphbean.jar;C:\oracle\orads9i\jlib\LW_PfjBean.jar;C:\oracle\orads9i\jlib\bigraphbean-nls.zip


Then I read one of the forum, and it says that I need to put the path under FORMS90_BUILDER_CLASSPATH
so this is what I have under it:
c:\project\security.jar;C:\oracle\orads9i\jlib\importer.jar;C:\oracle\orads9i\jlib\debugger.jar;C:\oracle\orads9i\jlib\utj90.jar;C:\oracle\orads9i\jlib\dfc90.jar;C:\oracle\orads9i\jlib\help3.jar;C:\oracle\orads9i\jlib\help3-nls.jar;C:\oracle\orads9i\jlib\oracle_ice5.jar;C:\oracle\orads9i\jlib\ewt3.jar;C:\oracle\orads9i\jlib\share.jar

Then I re-launched the form again and tried to import the java classes, but it gives me the same error:
PDE-PRE001 Internal error(depjv 1).


Please tell me what I did wrong?
thank you very much.
