File Upload Pluggable Java Component / Java Bean

Question

Dear Colleague,
I integrated the File Upload java bean into one of my Forms 9i forms. I also had it up and running (!!!), but after I rebooted the machine, I no longer receive the File Upload dialog window as I did originally. When I press the button which starts the File Upload, it never displays the window to select a file. My trigger is as follows:
begin
     /* Initialize the Java Bean */
     FileUploader.init('DOCU_BLOCK.FILE_UPLOADER','LOAD_CALLBACK_TRIGGER');
     /* Make sure the file is compressed on upload */
     FileUploader.setCompressed(true);
     /* Do the load to the c:\rolic\RKMS_documents\ directory on the server */
     FileUploader.UploadFile (:PARAMETER.file_destination);
/* Error Handling */
exception
when FileUploader.FileUploaderEx then
message (FileUploader.GetError);
end;
I have the "uploadclient.jar" file in my folder: C:\oracle9iDS\forms90\java
I list the "uploadclient.jar" file in the forms config file, formsweb.cfg as follows:
archive_jini=f90all_jinit.jar, uploadclient.jar, RKMS_images.jar
and I reference the uploadserver.jar in the default.env file as part of the CLASSPATH as follows:
CLASSPATH=c:\oracle9iDS\jlib\debugger.jar;c:\oracle9iDS\jlib\ewt3.jar;c:\oracle9iDS\jlib\share.jar;c:\oracle9iDS\jlib\utj90.jar;C:\oracle9iDS\forms90\java\UploadServer.jar
=========================================================
- Why did this work before I rebooted and now no longer???
- Any tips? Ideas?
=========================================================
The uploadclient.jar file also successfully loads as shown in the Java Console:

HI,
I'm facing nearly same problem.
When i press a button in my form to enable client to select image from there local computer, following code executes ( WHEN-BUTTON-PRESSED)
declare
     exSetup EXCEPTION;
     hButton ITEM := Find_Item('UPLOAD.SELECT');
begin
if (:upload.output_dir is null) then
MsgBox.Show(MsgBox.STOP_ALERT,FileUploader90,'Error: A output directory on the middle tier must be specified');      
raise exSetup;
end if;
FileUploader.UploadFile(:UPLOAD.output_dir);
/* (:UPLOAD is a control block and output directory is a text field char 1000 having initial property = D:\IMAGE) */
exception
When FileUploader.FileUploaderEx then
     MsgBox.Show(MsgBox.STOP_ALERT,FileUploader90,'Error During Upload: '||FileUploader.getError);      
When exSetup then
null;
end;
There is no compiliation error.
Runtime error is " Error During Upload: Desitnation directory does not exists or is not writeable ".
Infact destination directory D:\IMAGE exists and is readable/writable to any one ??
Any Help possible
