RE: openMapApplet and .jar data

I don't actually want to have to alter the policy to use the jar file - I
should be able to open data from the jar without that FilePermission, after
all the code is run from the jar without the FilePermission.

Hello Barney,

Have you tried the "policytool" ?

In case you haven't, you could try launching the tool. The tool would search
in default loactions for the java.policy file, ( if you are running Windows
95/98, this location would be C:\Windows ).

You could also need to edit the policy.url parameters in the java.security
file under the lib\security folder to indicate the locations from where you
would want the policytool to load your policy file.

You could then add policies and then add/edit permissions as part of your
policy. For starters you could set "All Permissions", only that would open
up security on your system. Remember to save the file when you are done ...

After that run the policytool again and make sure that your policy file gets
loaded.

Try running the applet after that ...

Hope this helps.

Regards,
Pradeep.
