RMI with JMF - Pls help

Question

Hi all,
I am trying to develop some program to allow user to activate video recording over the network. The basic idea of what I am doing is this: I have implement a Object to handle recording from a web cam. The recording work fine on a single JVM. The code follows
// Get the processor's output, create a DataSink and connect the two.
DataSource outputDS = processor.getDataOutput();
try {
MediaLocator m2 = new MediaLocator("file://c:"+fileName+"." +"avi");
datasink = Manager.createDataSink(outputDS, m2);
datasink.open();
datasink.start();
In order to achieve the remote invocation of the method, I expose the method as an RMI interface. However an exception : java.lang.RuntimeException: No permission to write files from applets is thrown when the program attempts to execute datasink.open().
The policy file that was use is as follows
grant {
permission java.security.AllPermission;
Any advise is appreciated. Thanks in advance
Regards

Answer 1

In the Sun Java control panel, in the runtime parameters box, type
-Djava.security.policy=c:\mypolicy.policy
where c:\mypolicy.policy is the policy file you are using.
Warning : your setting of
grant { permission java.security.AllPermission; };
will allow all applets, even ones from the Internet, full access to your machine.
At least put machine specific permissions in.

Owen
