解决方法：

一般问jes环境权限错误，

/export/home/sun_app_data/domains/domain3/config/server.policy

增加以下权限

grant {
permission java.lang.reflect.reflectpermission "suppressaccesschecks";
};
grant {
permission java.lang.runtimepermission "setContextClassLoader";
};
grant {
permission java.lang.RuntimePermission "getProtectionDomain";
};
