Java Application Server PE

If you are trying to use the Flex Data Services Project Template with the Java Application Server PE you might get the following error.

Error: java.security.AccessControlException: access denied (java.lang.RuntimePermission createClassLoader)
Cause: the default settings of the SUN server policy settings does not allow classloaders within webapplications.

Solution: Simply replace the policy file with one that contains the following grant entry:

edit: C:\Sun\AppServer\domains\domain1\config\server.policy

add: This towards the bottom of the policy file.

grant {
// Allow everything for now
permission java.security.AllPermission;
};
