Re: openMapApplet and .jar data

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.
