小编Qua*_*dir的帖子

我在Vista 64位上使用Java 6 64位和STANDALONE Tomcat 6.0.18.我正在使用struts 1.3.10和tile进行Web应用程序.现在,当我对java或jsp文件进行更改时,在重新加载页面时它们不可见.我必须在Tomcat Manager中手动重新加载Web应用程序才能查看更改.我的网络应用配置如下:

$CATALINA_BASE/conf/Catalina/localhost/dashboard.xml

<Context docBase="D:/mydata/projects/PatchworkSystems/development/Dashboard/webapp"
         path="/dashboard"
        reloadable="true" antiJARLocking="true" antiResourceLocking="true" debug="1" />

任何帮助是极大的赞赏.

谢谢Quadir

我正在尝试使用ProcessBuilder和Process执行命令(例如ps -ef | grep apache).只要'ps -ef'的输出很小,代码就可以工作.但如果输出太大,程序就会挂起.有没有办法来解决这个问题？这是基于[ http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html]的代码

#### Program.java ####
    import java.io.BufferedOutputStream;
    import java.io.File;
    import java.io.IOException;
    import java.io.OutputStreamWriter;
    import java.io.PrintWriter;

    import java.util.ArrayList;
    import java.util.Collections;
    import java.util.List;
    import java.util.Map;

    public class Program {

        private List<String> command;

        public Program(String commandString) throws IOException {
            this(commandString, null);
        }

        public List<String> getCommand() {
            return this.command;
        }

        private void setCommand(String filename, String location, String commandString, List<String> parameters) throws IOException {
            if(filename != null) {
                commandString = new File(location, filename).getCanonicalPath();
            }

            this.command = 
                Collections.synchronizedList(new ArrayList<String>());

            this.command.add(commandString); …

在下面的代码中,我试图通过产生优先级较低的线程来获得更高优先级的线程.但它似乎不起作用,优先级较低的线程似乎在较低优先级的线程完成后运行.谁能解释我做错了什么？

import java.util.ArrayList;
import java.util.List;

public class TestThreadPriority extends Thread {

    static List<String> messages = new ArrayList<String>();

    public void run() {
        Thread t = Thread.currentThread();
        int priority = t.getPriority();
        String name = t.getName();
        messages.add(name + ":" + priority);        
        Thread.yield();
        messages.add(name + ":" + priority);
    }

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Thread t = Thread.currentThread();
        t.setPriority(MIN_PRIORITY);
        int priority = t.getPriority();
        String name = t.getName();
        messages.add(name + ":" + priority);

        Thread tp1 = new TestThreadPriority();
        tp1.setPriority(MIN_PRIORITY); …
