JRE 1.4 Policy File

I've been looking everywhere but can't find a solution to this:

I have an applet that prints to a barcode printer. Unfortunately as
this applet is served from a silverstream (ver 3.7.5) server I can't
just use a jar file and sign it (because silverstream just will not
server the jar file correctly). The applet will run on an intranet
only but I can only get it to work but setting the ploicy file to
AllPermissions. I am a bit loath to do this and would much prefer
just to set Printing permisions in the policy file. Does anyone have
any idea what permissions i would need? or indeed if it is possible?
i am running JRE 1.4.2_04 on the clients.

Sun has a giant list of all permissions you can comb. See the link

I've looked through these docs but there is no mention of the
permissions needed for any class in the Javax.print package. Its not
a major problem (as its my applet running on my intranet), its just I
may need to do this for our web site at some point in the future and
thought i'd try and figure it out before hand.

Thanks for you reply.

Are you getting an exception that mentions a failed permission?

Is the problem in the URL area?

I don't get any exceptions. The java plugin throws up an alert saying
this applet is trying to print do you want to allowit? with Yes/No
buttons. If you click yes the applet carries on executing but
PrintServiceLookup.lookupPrintServices(null, null) always returns a
zero length array. If I set a policy file with AllPermissions then it
all works as it should. As you say it may be somthing to do with url
or maybe sockets as the javax.print package is IP compatible. I don't
have the time to do any testing this week but I'll post anything I
find when I can run some tests.

cheers
