java.security.AccessControlException : access denied ("java.net.SocketPermission" "localhost:1527" "listen,resolve")

Question

我又不得不面对这个错误。

Fri Sep 16 17:17:29 CEST 2016 : access denied ("java.net.SocketPermission" "localhost:1527" "listen,resolve")

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

他们都在同一行:

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

我的机器是Linux 16.04.01，服务器是Glassfish4

还有其他可能的地方可以编辑 java.policy 文件吗？ 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";
};
