     FileDrop.java   FileDropBean.java

The implementation class of the Java Bean

     oracle.forms.gp.FileDropBean

The event fired by the Java Bean


 DROP


The full filemane is transmitted in the EVENT_MSG parameter.

DECLARE
 l_eventName varchar2(30) := :system.custom_item_event;
 l_eventValues ParamList;
 l_eventValueType number;
 l_event_msg VARCHAR2(255);
BEGIN
   IF l_eventName = 'DROP'
   THEN
      l_eventValues := get_parameter_list(:system.custom_item_event_parameters);
      get_parameter_attr(l_eventValues,'EVENT_MSG',l_eventValueType, l_event_msg);
      IF :system.record_status <> 'NEW'
      THEN
         create_record;
      END IF;
      :ctrl.file_location := l_event_msg;
   END IF;
END;

The sample dialog

     . Download the filedrop.zip file

Hi there,

I know this is an old post, but I was hoping you might be able to help with something.
I was using the bean with forms 11g. After an upgrade to 12c the bean no longer works. The drop square seems completely inactive and nothing happens.
Do you perhaps have any ideas?

Thank you!

Sorry, but it is a long time I stopped working whith that... I ha no idea. Display the Java console at runtime. Maybe it is related to new Java Applet policies...

Hi,

I can't run in administrator mode, is there any restrictions or suggestions?

Thanks in advance!

Hi,


I was really interested by your Java Bean ... but I have this error message, could you help me ?


error java.lang.UnsupportedClassVersion ....


 


Thanks

This means that the Bean was compiled with a more recent version than the JRE you use to run Form. Maybe you're still using the old JInitiator. Upgrade to a more recent JRE.

Hi Geert,


 


I'm having trouble with the filedropper: the demo fmb is ok but when I enhance it to have a base tabled block to store Blobs using webutil it freezes the application and the file explorer (during
the communication with the bean in th WCIE).  Can you help me ?

Gert has no access to my blog, so I suggest you to ask that question on the Forms.PJC.Bean forum.
Choose one of the first two sub-forums (PJC or JavaBean)  ;-)

Hello,


Regarding the FileDropBean:


Am I right to conclude that only the file-name is send from applet to the Forms runtime (connected and running frmweb.exe) on server?


In other words: no bytes are transfered to the server?


Thanks, regards, Stephan

Yes, you are right.
