在Sun Java System Application Server （8.2）版本 会发生

java.security.AccessControlException

解决办法

进入/config目录 修改 server.policy 文件 增加

grant codeBase "file:${com.sun.aas.instanceRoot}/applications/J2EE-modules/jreport/-"{
??? ?permission java.util.PropertyPermission "*", "read,write";
??? ?permission?? java.security.AllPermission "*", "read,write";
};

注意：jreport 问要部署的war包

or
grant{
??? ?permission java.util.PropertyPermission "*", "read,write";
??? ?permission?? java.security.AllPermission "*", "read,write";
};
