如何在单击"确定"按钮时添加监听器JOptionPane.INFORMATION_MESSAGE.

我的JOptionPane是:

JOptionPane.showMessageDialog(null, "Your password is: " + password, "Your Password", JOptionPane.INFORMATION_MESSAGE);

我们已经安装了我们的应用程序版本(在生成应用程序包之前没有包含任何工具或cobertura jar).

安装完成后,我们使用cobertura对所有jar进行了检测,并在java classpath中包含了cobertura jar文件.但在启动应用程序时它会给出以下错误.

任何输入都会有所帮助,谢谢.

Java版"1.7.0_25"
cobertura ver 1.9.4.1

我在我的Java项目中使用jSch for SFTP.我想获取目录中的所有文件属性.但是有两种方法可以检索文件或目录的文件属性.

1. public SftpATTRS stat(String path)
2. public SftpATTRS lstat(String path)

这两种方法有什么区别？请告诉我有用吗???

我正在使用 Java 制作一个文件上传应用程序jSch。我想根据文件的创建日期等将文件放在不同的目录中。

我有一个主目录"/var/local/recordingsbackup/"，我在其中创建其他目录并将数据放入其中。

为了达成这个：

• 我必须创建 Dir'y 之类的 "/var/local/recordingsbackup/20140207/root/SUCCESS/WN/"并将数据放入其中。

到目前为止我已经尝试过：

private void fileTransfer(ChannelSftp channelTarget, temp_recording_log recObj, String filePath) {

        int fileNameStartIndex = filePath.lastIndexOf("/") + 1;
        String date = new SimpleDateFormat("yyyyMMdd").format(recObj.getCalldate());
        String fileName = filePath.substring(fileNameStartIndex);
        String staticPath = "/var/local/recordingsbackup/";
        String completeBackupPath = staticPath + date + "/" + recObj.getUsername() + "/" + recObj.getStatus() + "/" + recObj.getDisposition() + "/";

        try {
            InputStream get = SourceChannel.get(filePath);
            try {
                channelTarget.put(get, completeBackupPath + fileName);
            } catch (SftpException e) { …

我使用jSch创建了一个简单的程序来打印远程目录中的总文件名.在目录中,只有7个文件,但在我的控制台上,我得到两个额外的文件名.和...

从哪里来的这些文件,或它的垃圾???

我的Java代码:

import com.jcraft.jsch.ChannelSftp;
import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;
import java.util.Vector;

public class DownloadFileSFTP {

public static void main(String[] s){
    String user = "user";
    String password = "1234";
    String host = "remoteIP";
    int port = 22;
    String sourcePath = "/home/remoteSFTP_Files/";
    String destinationPath = "/home/user/SFTP_files/";
    Session session = null;
    ChannelSftp sftp = null;

    try {
        JSch jsch = new JSch();
        session = jsch.getSession(user, host, port);
        session.setPassword(password);
        session.setConfig("StrictHostKeyChecking", "no");
        session.connect();
        System.out.println("Session created");
        sftp = (ChannelSftp) session.openChannel("sftp");
        sftp.connect();
        System.out.println("SFTP …

我正在创建一个Java程序,我将文件上传到特定路径上的服务器.我使用jSch了sftp.

因此,在上传文件之前,我想检查服务器上是否存在给定目录.

if(path exists)
    //upload file to the location
else
    //create the directory and then upload the file.

如何检查路径是否存在？

注意:我正在客户端上执行代码,该代码将检查服务器上是否存在远程目录.所以请不要建议File.exists().

我不明白为什么我得到空列表criteria,我的表中有数据.

我得到List的代码:

hibernateSession_destination = HibernateUtilReports.INSTANCE.getSession();

        Criteria criteria = hibernateSession_destination.createCriteria(nr_rec_backup_rule.class);
        List list = criteria.list();
        System.out.println("List length =======  " + list.size()); // prints size = 0

我的HibernateUtilReports.java:

public enum HibernateUtilReports {
    INSTANCE;
    public static SessionFactory sessionFactory = null;

private synchronized SessionFactory getSessionFactory(){

    if(sessionFactory == null){
        Configuration config = new Configuration();
        config.addAnnotatedClass(contaque_recording_log.class);
        config.addAnnotatedClass(contaque_servers.class);
        config.configure("reportshibernate.cfg.xml"); // is here any error???

        Properties configProperties = config.getProperties();
        ServiceRegistryBuilder serviceRegisteryBuilder = new ServiceRegistryBuilder();
        ServiceRegistry serviceRegistry = serviceRegisteryBuilder.applySettings(configProperties).buildServiceRegistry();
        sessionFactory = config.buildSessionFactory(serviceRegistry);
    }
    return sessionFactory;
}

public Session …

我正在通过JSON数据动态创建一个表,但是将所有<td>元素放在同一个<tr>而不是两个不同的行中.

JavaScript部分:

$('button').click(function() {
var str = '[{"callType":"IN","extension":"150","name":"avis","phoneNumber":"9876541230","skill":"English","status":"INCALL","time":"10:50:23"},{"callType":"OUT","extension":"857","name":"sys","phoneNumber":"9658741235","skill":"Hindi","status":"WAITING","time":"08:40:51"}]';

var list = JSON.parse(str);
for (var i = 0; i < list.length; i++) {

    var tr = $('#t').append('<tr class="laOriginal" value="user"></tr>');
    var radioBtn = $('<input type="radio" name="radioAgent" value="' + list[i].name + '" />"  id="radioAgent' + list[i].name + '"');
    tr.append(radioBtn);
    tr.append("<td>" + list[i].name + "</td>");
    tr.append("<td>" + list[i].extension + "</td>");
    tr.append("<td>" + list[i].skill + "</td>");
    tr.append("<td>" + list[i].phoneNumber + "</td>");
    tr.append("<td>" + list[i].status + "</td>");
    tr.append("<td>" + list[i].callType + "</td>"); …

重新启动雄猫或停止雄猫服务器时，我收到这些警告和错误。它不会干扰我的项目，但我想这是一个严重的问题，没有。的用户增加。

PS我已经使用了hibernate进行数据库连接，使用了显示表的显示标签库，并且使用了jsp / servlet。

我创建了一个名为main的类ArrayProgram,另一个名为Calculator1.

编纂包括:

class ArrayProgram {

    public static void main(String[] shiva) {
        int result[] = Calculator1.generateRandomChar;
        System.out.println(result);
    }
}

class Calculator1 {

    public static char generateRandomChar() {
        int rand = (int) (Math.random() * 52);
        char base = (rand < 26) ? 'A' : 'a';
        return (char) (base + rand % 26);
    }
}

编译和以后运行后,我得到以下错误.

ArrayProgram.java:5: cannot find symbol
symbol : variable generateRandomChar
location : class Calculator1
int result[]=Calculator1.generateRandomChar;

我哪里做错了..？
