Runtime.exec is prohibited by default. Unless the applet is signed, or the local security policy altered, it can't be used in an applet. [ July 18, 2007: Message edited by: Ulf Dittmer ]

Then the applet I'm working on must be signed. But I don't see any warning message like starting WebStart. If I accept the signature, then I can run the application. So the user maybe confused when my applet invokes an OS command. Because he just thinks applet can't do this.
What I expect is maybe I still need to use Runtime.exec do something. But I don't want to let the user be frightened.

Well, the thinking is that the user understands that if he accepts the certificate, then the applet is allowed to do (just about) anything it pleases. So he shouldn't accept a certificate from someone he doesn't trust not to format his hard drive, or email his personal files to random people.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
