I need some assistance in applet development. Here is a brief description of
a system I'm attempting to design.

 I'm using applets imbedded in web pages to display database records
(therefore read from the database) and also to allow additions of records
(therefore write to the database). The webpages are all displayed via a
company Intranet which can be accessed by the company sites all around the
world. All of the web pages, the applets and the database reside on a single
company Web Server in one location. Reports may be generated via the applets
which are in the form of a text file which is temporarily saved to the Web
Server to allow for immediate printing. The text file is read from the Web
Server and displayed in a separate applet frame. The text file may then be
printed to a printer local to the company site viewing the information via
selecting a Print Menu Item.

Do these applets required to be digitally signed to allow read/write access
rights? I am guessing not because all the reading and writing of files is
from the one hard drive (the Web Server) which is where all files reside.
Could someone confirm this?

Also, my biggest query, do the applets need to be digitally signed to allow
the displayed text file to be printed to a non-local (not the Web Server)
printer? Could anyone point me in the direction of how to create code to
allow the printing of the text file to a non-local printer?

Thanks in advance.

If I have understood your question :

You need digitally signed applets to read/write at the client machine.
To display(at client) / update database (at the server), you could
aswell use servlets in combination with applets which will server the
functionality. You may also need to consider the authentic machanisms
like password based or certificate based.

I do not think you can print from the applet on the server from which
it is downloaded.  You can  instead invoke a servlet from that applet
and ask it print. @see ToolKit class.

Hope you get some sort of inertia from this .

Good luck!.

Hi
The best to print is to convert the html in xml and then to pdf.
You can�t do this with fop of apache.
