SecurityException in my Applet

Question

I'm not good with Java but when I run my Applet in a simple HTML page, occurs the following error

SecurityException: Trusted loader attempted to load sandboxed resource from file : C:/Users/lucas/teste.jar

Edited: policy tool

I follow the tutorial but in the step 7, i got the following error

enter image description here

Translated:

Could not open file policy C:\Program Files\Java\jdk1.7.0_05\bin\raystore: sun.security.provider.PolicyParser$ParsingException line 1: expected [;] found[pípí]

Show the complete line you used to sign the jar with jarsigner. If the path has spaces you may want to add "" around it. — Sully, Jul 16 '12 at 15:18

Applets run in a sandbox with limited permissions.

http://docs.oracle.com/javase/tutorial/deployment/applet/security.html

You can sign your Applet as detailed below if you want to override these default permissions.

When I create the policy file, I can't load him. Error: Found (some strange caracteres) Expect(;) – Lucas_Santos Jul 16 '12 at 15:54
Digital signing means the policy file is not needed. Don't waste more time with policy files. – Andrew Thompson Jul 16 '12 at 23:27

jarsigner is in JDK, not in JRE. Check you have that in your path.

Alternatively write all the command path e.g. %PROGRAMFILES%\Java\jdk1.7.0_01\bin\jarsigner.exe
