我再次面对这个错误。

这次我无法解决编辑java.policy文件的问题。

java -version的结果：

openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-3ubuntu1~16.04.1-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

我在

中找到了java.policy文件

/etc/java-8-openjdk/security
/usr/java/jdk1.8.0_25/jre/lib/security

他们两个都有一行：

permission java.net.SocketPermission "localhost:1527", "listen,resolve";

我的机器是Linux 16.04.01，服务器是Glassfish4

是否有其他可能的位置来编辑java.policy文件？还有其他可能的原因吗？

Answer 1

首先，运行derby批处理文件sysinfo.bat以确定正在使用哪个JDK / JRE来运行它。如果您无法确定它，请转到计算机的环境变量并检查JAVA_HOME的值。

然后转到JDK / JRE的\jre\lib\security文件夹并添加：

grant {
    permission java.net.SocketPermission "localhost:1527", "listen";
};

Answer 2

来自https://docs.oracle.com/cd/E18930_01/html/821-2418/beabx.html：

每个GlassFish Server域都有自己的全局J2SE策略文件，位于domain-dir / config中。该文件名为server.policy。

java.security.AccessControlException：拒绝访问（＆＃34; java.net.SocketPermission＆＃34;＆＃34; localhost：1527＆＃34;＆＃34; listen，resolve＆＃34;）
