的AccessControlException連接到HTTP服務器從Tomcat Servlet時

Question

我試圖讓我的tomcat的servlet下載多個文件，但我有Apache和Tomcat在同一臺服務器上運行，所以我想這就是爲什麼它不工作。我在不運行Apache的服務器上測試過，一切都很好。

這裏的時候我嘗試使用新的網址（fileUrl）.openStream（），我發現了異常：

Opening input stream Attempted to download: http://www.stefankendall.com/files/test.txt java.security.AccessControlException: access denied (java.net.SocketPermission www.stefankendall.com:80 connect,resolve) 

如何通過Tomcat的運行HTTP下載，而在同一時間運行的Apache？我卡住了嗎？

編輯：
無論我做什麼，我都無法超越tomcat。這裏的03catalina.policy：

// ========== CATALINA CODE PERMISSIONS ========================== =============

// These permissions apply to the logging API 
grant codeBase "file:${catalina.home}/bin/tomcat-juli.jar" { 
     permission java.util.PropertyPermission "java.util.logging.config.class", "read"; 
     permission java.util.PropertyPermission "java.util.logging.config.file", "read"; 
     permission java.lang.RuntimePermission "shutdownHooks"; 
     permission java.io.FilePermission "${catalina.base}${file.separator}conf${file.separator}logging.properties", "read"; 
     permission java.util.PropertyPermission "catalina.base", "read"; 
     permission java.util.logging.LoggingPermission "control"; 
     permission java.io.FilePermission "${catalina.base}${file.separator}logs", "read, write"; 
     permission java.io.FilePermission "${catalina.base}${file.separator}logs${file.separator}*", "read, write"; 
     permission java.lang.RuntimePermission "getClassLoader"; 
     // To enable per context logging configuration, permit read access to the appropriate file. 
     // Be sure that the logging configuration is secure before enabling such access 
     // eg for the examples web application: 
     // permission java.io.FilePermission "${catalina.base}${file.separator}webapps${file.separator}examples${file.separator}WEB-INF${file.separator}classes${file.separator}logging.properties", "read"; 
}; 

// These permissions apply to the server startup code 
grant codeBase "file:${catalina.home}/bin/bootstrap.jar" { 
     permission java.security.AllPermission; 
permission java.net.socketPermission "*:80", "connect, resolve"; 
}; 

// These permissions apply to the servlet API classes 
// and those that are shared across all class loaders 
// located in the "lib" directory 
grant codeBase "file:${catalina.home}/lib/-" { 
     permission java.security.AllPermission; 
     permission java.net.socketPermission "*:80", "connect, resolve"; 
}; 

grant codeBase "file:${catalina.home}/webapps/-" { 
permission java.security.AllPermission; 
permission java.net.socketPermission "*:80", "connect, resolve"; 
};

你的問題與在同一個盒子上運行的程序是否存在無關;它擁有了SecurityManager的Tomcat中的存在（這可能意味着你正在運行的是舊版本的Tomcat）做。

下面是詳細的how to configure the Tomcat SecurityManager文檔。在你的情況，你會添加一些行到local.policy文件，沿

grant codeBase "file:${catalina.home}/webapps/-" { 
    permission java.net.SocketPermission "*:80", "connect"; 
};
