Signed Applets, JNI and DLLs

I have a question about signed applets and dll's. I'm going to do an applet that uses a bunch of dll's that resides on the harddrive. If my applet is signed and the user agrees to run the applet, will the dll's be able to perform anything?

I was looking for if I might run into any resource/clearance issues if my applet runs the dll's. Basically the dll's are responsible for things like voice recording+voice output (through openAL afaik), and RTP and SIP implementations. So I want to make sure there's no issue with accessing that stuff if my applet is signed and user agrees to run it.

Thanks

Solution

  • These are the requirements :

    • your applet is signed / user aggrees to run it
    • the dlls that do the JNI part must be on the java.library.path
    • your user must have sufficient privileges to run the dlls

    I've done it, so there is no reason you can't do it too
