For savtey issue you cannot load/save files from an applet
You should have two "java.policy" files on your HD. Here You should give
additional permission rights
Example File location:
c:\java\jre\lib\security\java.policy
c:\programs\java\jre1.4.1\lib\security\java.policy
adding this line will work, but is very insecure:
permission java.util.PropertyPermission "<ALL_FILES>", "read";
for a complet documentation: search the web.
