Solution and cause -:

Cause-:This error will occur if security is violated as the user does not have the necessary permissions to load the applet.

See the line -:
Caused by: java.security.AccessControlException: access denied (java.util.PropertyPermission http.keepAlive write)


Solution-:

Edit and append the snippet below, to the end of the policy file (The typical location of your policy file is C:\Program Files\Java\jre1.5.0_16\lib\security\java.policy). If you are running a different JRE (i.e. 1.6), then the folder name 'jre1.5.0_16' will obviously reflect your version of the java runtime environment.

grant codeBase "http://localhost/-" {
permission java.security.AllPermission;
permission java.io.FilePermission "<<ALL FILES>>", "read";
permission java.io.FilePermission "<<ALL FILES>>", "write";

};
