我正在尝试在文件夹中创建一个文件但我得到例外

java.security.AccessControlException: Access denied

我在Windows环境中工作.我可以从Windows资源管理器创建一个文件夹,但不能从Java代码创建.

我该如何解决这个问题？

嘿我AccessControlException: access denied在尝试启动我正在编写的RMI应用程序时遇到了问题,如果我在默认端口1099上打开它,或者在另一个动态端口,我的策略文件当前打开它,我无法理解为什么会出现此异常授予一切(在应用完成后会改变).

我被困在哪里出错了,任何帮助都会很有用

我的代码

public class Main {

/**
 * @param args the command line arguments
 */
public static void main(String[] args) throws RemoteException, AlreadyBoundException, MalformedURLException {
     if (System.getSecurityManager() == null)
     {
        System.setSecurityManager ( new RMISecurityManager() );
     }

     CreditCardServer ccs = new CreditCardServer();

     int port = 1099;

     try {
        port = Integer.valueOf(args[0]);
        }
     catch (Exception e)
        {
        System.out.println("Invlaid Port");
        }

     if (((port <= 65535) && (port >= 49152)) || port ==1099)
     {
     System.out.println("Valid Port");

我从Netbeans 6.8中尝试在Tomcat上重新部署webapp时遇到以下错误.它可能与保存和热交换功能的新部署有关.有任何想法如何解决这个问题？

我创建了一个小程序,打开JFileChooser一个文件,点击一下即可选择一个文件JButton.当我在Eclipse中运行它时,它工作正常.当我将它嵌入带有applet标签的HTML页面时,单击按钮时没有任何反应.

任何关于为什么JFileChooser不在浏览器中打开的建议都会受到赞赏,但我的主要问题是如何调试这个？我无法在Google上找到有关如何将Java控制台添加到Firefox 3.6或Chrome的任何内容.有没有办法获得有关JFileChooser无法打开的原因的某种信息？

调试在下面的评论中回答

所以控制台说有一个访问被拒绝的异常,我猜是因为我还没有"签名"applet.在签署applet时,开发过程应该是什么？在我可以在浏览器中测试之前,是否必须使用由有效CA颁发的证书对其进行签名,或者在测试时是否可以执行一些简单的操作？

这是我的代码:

package com.putapplet;

import java.awt.FlowLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
import java.net.URL;

import javax.swing.JApplet;
import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JProgressBar;
import javax.swing.SwingUtilities;


@SuppressWarnings("serial")
public class PutToS3Applet extends JApplet {

    private static long maxFileSizeInBytes = 1048576;

    private static String listenerUrl = "xxx";
    private String listenerQueryString;

    private String signedPutUrl;

    private JProgressBar progressBar;
    private JButton button;
    private JLabel messageField; …

我有一个小Java小程序,我有一个恼人的问题.我使用jarsigner工具(遵循这些说明)使用我自己的密钥库签署了我的JAR .

Java Applet下载已签名的 JAR并尝试使用扩展类URLClassLoader启动它.这个JAR试图执行这行代码:

ClassLoader.getSystemClassLoader().getResource("aResource");

它失败了,堆栈跟踪很大,完成了:

Caused by: java.security.AccessControlException: access denied ("java.lang.RuntimePermission" "getClassLoader")
    at java.security.AccessControlContext.checkPermission(AccessControlContext.java:366)
    at java.security.AccessController.checkPermission(AccessController.java:555)
    at java.lang.SecurityManager.checkPermission(SecurityManager.java:549)
    at java.lang.ClassLoader.getSystemClassLoader(ClassLoader.java:1476)
    at test.SecondJAR.main(SecondJAR.java:8)

(test.SecondJAR的第8行对应于getResource(...)方法

启动Java Applet时,如果用户信任发布者,则会提示用户接受证书:

即使我接受它,也会发生异常.即使我安装了证书,并且自动接受了提示消息,也会发生异常.

我也试过这个:

AccessController.doPrivileged(new PrivilegedAction<Object>() {
    public Object run() {
        ClassLoader.getSystemClassLoader().getResource("aResource");
        return null;
    }
});

它失败了同样的例外.

任何帮助,将不胜感激!

我有一个简单的自签名小程序(用keytool和jarsigner完成):

public class NetAppletLauncher extends JApplet {

    private static final long serialVersionUID = 1L;

    public void init() {
        exec("notepad c:/hello.txt");
    }

    public void exec(String command) {

        try {

            // launch EXE and grab stdin/stdout and stderr
            Process process = Runtime.getRuntime().exec(command);
            //      OutputStream stdin = process.getOutputStream();
            InputStream stderr = process.getErrorStream();
            InputStream stdout = process.getInputStream();

            // "write" the parms into stdin
//          stdin.write(arguments.getBytes());
//          stdin.flush();
//          stdin.close();

            // clean up if any output in stdout
            String line = "";
            BufferedReader brCleanUp = …

我正在编写一个elasticsearch插件,它依赖于从磁盘上的文件中读取数据.当我尝试在我的代码中访问此文件时,我得到以下异常.

有没有推荐的方法来访问elasticsearch插件中的文件？有没有快速的解决方法来访问我的插件中的文件？

我知道这是常见的事情,使用早期版本的chrome我用来设置"C:\ Program Files(x86)\ Google\Chrome\Application\chrome.exe"--args --disable-web-security --user Chrome快捷方式选项卡中的-data-dir,以避免"Access-Control-Allow-Origin"错误.使用最新版本,似乎此修复程序不再起作用.安装最新版本53.0.2785.89 m后,这是控制台中的错误

XMLHttpRequest无法加载https://example.org:15003/apps/services/preview/rr/common/1.0/default/index.html.对预检请求的响应未通过访问控制检查:当凭证标志为真时,不能在"Access-Control-Allow-Origin"标头中使用通配符"*".因此不允许原点' http:// ibm-pb7en65:10080 '访问.XMLHttpRequest的凭证模式由withCredentials属性控制.

我不确定要添加哪些附加属性以避免"Access-Control-Allow-Origin"错误.这有什么办法可以实现吗？

我有一个单元测试,它使用Elasticsearch的集成测试框架.使用Elasticsearch 2.0.0-2.1.2执行时工作正常,但是当我在IntelliJ中运行最新的Elasticsearch 2.2.0时,我得到以下内容,知道需要调整哪些不使用IntelliJ中的安全管理器？
