Hello Team,
I followed the instructions in the how-to section to create a form to be able to upload and download files.
It works very good. However, it does not work for html files.
I have done that before using PL/SQL outside HTMLDB and I remember that this involved the creation of a table: ****PORTAL_CONTENTSPART which is equivalent in structure to the table WWV_FLOW_FILE_OBJECTS$PART.
So now how this table can be used to store HTML contents.
Thank you and appreciate your help in advance.
