Runtime.getRuntime().exec() java.io.FilePermission denied

[moongeegee]

I can execute Runtime.getRuntime().exec() correctly without any
probelm.
After I convert to Applet, I got the following error:
java.security.AccessControlException: access denied
(java.io.FilePermission <<ALL FILES>>

I could not access server configure file to grant permission. Please
help me. What should I do? Thanks a million.

"An applet cannot start any program on the host that is executing it."
Imagine how unsafe it would be if this were permitted.

In production the applet will be running on the client computer not on
your server. If you are trying to access a file on the server, you need
to access the file with a server side process and then pass the data to
the applet. If you are trying to access a file on the client, you need
to sign your applet.

Don't cross post - you're just clogging the system and making it less
likely that you will get an answer.

Sorry for multiple post.

I need to use Runtime.getRuntime()exec(ln -s xxx xxx) for linking a
file.
Would anyone give me other alternative way to solve this issue ?
Thanks.

Whenever applets do anything interesting, such as call exec, they
have to be signed.

Whenever applets do anything bizarre, such as exec("ln -s"), one has to question
the wisdom of the intent...

Better than multi-posting ...
