将Java Applet嵌入网页中

Question

I've built a java applet and am trying to embed it into an HTML file on my server. 我已经构建了一个Java小程序，并试图将其嵌入到服务器上的HTML文件中。 When I access the page, the applet tries to load but then crashes with a ClassNotFoundException on .applet.BookingApplet.class (which is the name of the applet, where applet is the name of the package the applet is in.) 当我访问该页面时，该applet尝试加载，但随后在.applet.BookingApplet.class上发生ClassNotFoundException崩溃（这是applet的名称，其中applet是该applet所在的包的名称。）

   <body>
    <script src ="http://java.com/js/deployJava.js"></script>
    <script>
        var attributes = {
        codebase: '/webapp/HelpSessions.jar', 

       code: '/webapp/HelpSessions.jar/applet/BookingApplet.class',
       archive: '/lib/javax.persistence.jar, /lib/javax.validation-1.0.0.GA.jar, /lib/joda-time-2.1.jar, /lib/mail.jar, /lib/mysql-connector-java-5.1.23-bin.jar',
       width: 800, 
       height: 600        
        };
        var version = "1.6"
        deployJava.runApplet(attributes, version);
        </script>
</body>

This is the first time I've tried to do anything like this, so I'm sure this is just a syntactical error with the way I'm referring to the class files in the HTML. 这是我第一次尝试做这样的事情，所以我确定这只是我在HTML中引用类文件的方式上的语法错误。 I can post any other code if needed, but I don't think its relevant because the applet runs fine in AppletViewer. 如果需要，我可以发布任何其他代码，但是我认为它无关紧要，因为applet在AppletViewer中运行良好。

I'm not going to sleep tonight till I get this thing running... 直到我让这个东西运行起来，我今晚才睡觉。

EDIT: To simplify things, I tried moving everything into one folder so I wouldn't have to deal with the codebase. 编辑：为简化起见，我尝试将所有内容移动到一个文件夹中，因此我不必处理代码库。 Here's what it looks like now: 这是现在的样子：

<html>
<head>
    <title>Schedule a Help Session</title>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
<body>
    <script src ="http://java.com/js/deployJava.js"></script>
    <script>
        var attributes = {

       code: '/applet/BookingApplet.class',
       archive: '/lib/javax.persistence.jar, /lib/javax.validation-1.0.0.GA.jar, /lib/joda-time-2.1.jar, /lib/mail.jar, /lib/mysql-connector-java-5.1.23-bin.jar',
       width: 800, 
       height: 600        
        };
        var version = "1.6"
        deployJava.runApplet(attributes, version);
        </script>
</body>

and I'm getting the same ClassNotFoundException. 和我得到相同的ClassNotFoundException。 Also, I can see an InterruptedException in the details on the java console, but it doesn't tell me where (if anywhere) in my code the exception is being caused. 另外，我可以在Java控制台的详细信息中看到InterruptedException，但是它没有告诉我在代码中的什么地方（如果有的话）引起了异常。

Change the code attribute to be "applet/BookingApplet.class". 将code属性更改为“ applet / BookingApplet.class”。 Currently you are using "/applet/BookingApplet.class". 当前，您正在使用“ /applet/BookingApplet.class”。

When Java reads a URL, it converts any '/':s to '.':s. Java读取URL时，会将任何'/'：s转换为'。'：s。 That will make the URL "/applet/BookingApplet.class" ".applet.BookingApplet.class". 这将使URL“ /applet/BookingApplet.class”“ .applet.BookingApplet.class”。 "applet/BookingApplet.class" will become "applet.BookingApplet.class", which is the correct one. “ applet / BookingApplet.class”将变为“ applet.BookingApplet.class”，这是正确的。

Just remember to set codebase to point to the directory where the "applet" directory is located. 只要记住将codebase设置为指向“ applet”目录所在的目录即可。
