java.security.AccessControlException: access denied (java.io.FilePermission

I have a third party service which is being invoked from my J2ee Web application. I have created a remote client class to invoke this service but I am getting  the folllowing exception while trying to access the Remote Client from Weblogic 11 G Server.

Fix: It can be fixed by providing security policy in the Java Options in your setDomainEnv file under bin directory of web logic installation:

I placed a policy file with grant all security level and set its location in the java options.

1. Place grant_all.policy in your config folder:

 grant {
  permission java.security.AllPermission;
};

2.  Add the following in JAVA_OPTIONS in setDomainEnv.

-Djava.security.policy=C:\weblogic\testdomain\config\grant_all.policy
