function updateServerList() {
    var i;

    for (i=0; i < servers.length; i++) {
     var server = servers[i];
     var ip = server['serverIp']


     var html = constructServer(i);
     var divId = '#server' + ip.replace(new RegExp("\\.", "mg"), "-");
     var visible = $(divId).find(".server_body").is(":visible");
     var div = $(divId);
     div.html(html);

     // Set div class.
     var prevState = div.attr('class').substring(7)
     if (prevState != server['state']) {

         if (server['state'] == 'ok') {
         console.debug(server);
         div.slideUp('fast', function(server) {
             $(this).removeClass();
             $(this).addClass('server_ok');
             var id = ipToId[server['serverIp']];
             console.debug(id);
             if (id == 0) {
             adjacentIp = servers[1]['serverIp'];
             adjacentDivId …

我有一个看起来像这样的流(除了更多东西):

<ret:EditUse>Broadcast</ret:EditUse>
<EditUse>Movie</EditUse>

我正在尝试使用sed清理它的XML:

sed "s_</?(ret:)?EditUse>__"

我已经使用RegexPal测试了正则表达式,但它似乎不适用于sed.关于什么是错的任何想法？

出于以下情况,这是重用section矢量的首选方式？

Iterator<Vector> outputIter = parsedOutput.iterator();

while(outputIter.hasNext()) {
    Vector section = outputIter.next();
}

要么

Vector section = null;

while(outputIter.hasNext()) {
    section = outputIter.next();
}

我的问题是,getInputStream()当我在发布到服务器后尝试打开流时挂起.用python编写的服务器给出了一条错误消息,让我相信它无法正确解析我的查询字符串.请帮我诊断一下这个问题.

我使用以下代码发布到Web服务器:

String boundarySolo = "--158211729626281";
String boundary = boundarySolo + "\r\n";
String contentHeader = "Content-Disposition: form-data; name=\"";
URL requestUrl;
URLConnection connection;
String queryString = new String();

try{
    requestUrl = new URL(config.getServerUrl());
    connection = requestUrl.openConnection();
    connection.setReadTimeout(1000);
    connection.setDoOutput(true);
    connection.setDoInput(true);

    connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundarySolo);

...

    outStream = new DataOutputStream(connection.getOutputStream());

    System.out.println("Writing bytes...");
    outStream.writeUTF(queryString);
    System.out.println("Bytes written");
    outStream.flush();
    System.out.println("Buffer flushed.");
    outStream.close();
    System.out.println("Stream closed.");

    try{
    inStream = new DataInputStream(connection.getInputStream());
    String buffer;

    System.out.println("Entering the loop.");

    while((buffer = inStream.readLine())!= null)
        System.out.println(buffer);

    System.out.println("Leaving the loop.");

    } …

如果我通过SSL或TLS连接到邮件服务器但使用PLAIN身份验证,那是否安全？

我正在尝试在java中调试Null Pointer Exception,但堆栈跟踪无益.它不能指向任何特别的东西:

 [exec] Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
 [exec]     at core.InputPanel.<init>(Unknown Source)
 [exec]     at core.Main.<init>(Unknown Source)

我怎样才能缩小这个空指针的位置？
