Hello everyone,

Oracle forms 11g 11.1.2.0.0
OS: Oracle Linux

We use webutil to upload files to the application server from the client machine, and stores them in a folder named JOB_DOCS on the application server (This folder is created as a databse directory too). File types are JPEG, GIF, PDF, TXT, BMP, DOC, XLS etc...
At a later stage when the user tries to view the uploaded documents, this was not getting displayed on the screen

on our windows server, when the user clicks on the print button we copy the file from the JOB_DOCS folder to the forms\java folder using the below command

HOST('COPY ' ||d:\JOB_DOCS\test.pdf||' '||'c:\oracle\middleware\as\forms\java\test.pdf ,NO_SCREEN);

once the file is under the forms\java folder then it is getting displayed on the screen to print or save, and later we remove the file from forms\java folder.

But my problem here is, recently we have installed our application on Oracle Linux server, and we have JOB_DOCS folder there, and the users can upload files to this folder also. How can we copy the file test.pdf from JOB_DOCS to forms/java in linux?
And what could be the reson for the document cannot be accessed from the folder where it is saved? We tried giving folder permissions, adding the folder to PATH variable etc.
