Question

我是JNLP的新手。我一直试图解决这个问题直接2天......我不知道...... 我在eclipse中有一个动态的web项目。我想在html中添加一个Applet。它工作正常，如果我不使用jnlp追加它。但如果我使用jnlp，它会抛出异常...... 请帮我.... 这是我的包结构：

  DaaS
DaaS\WebContent
\WebContent\AppletToJS.html
\WebContent\appletToJS.jnlp
\WebContent\FirstApplet.jar

“FirstApplet.jar”包含Applet类 - AppletToJS.java

这是我的jnlp文件：

<?xml version="1.0" encoding="UTF-8"?>     
<jnlp href="appletToJS.jnlp">
 <information>
    <title>Dynamic Tree Demo</title>
    <vendor>Dynamic Team</vendor>
 </information>
<resources>
    <!-- Application Resources -->
    <j2se version="1.6+" href="http://java.sun.com/products/autodl/j2se" />

    <jar href="FirstApplet.jar" main="true" />
</resources>
<applet-desc
     name="Applet To JS"
     main-class="acid.AppletToJS"
     width="300"
     height="300">
 </applet-desc>
 <update check="background"/>
</jnlp>

这是我的html文件：

<html lang="en-US">
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"/>

<body>
  <script src="http://www.java.com/js/deployJava.js"></script>
  <script>
    var attributes = { code:"acid.AppletToJS",  width:100, height:100} ;
    var parameters = {jnlp_href: "appletToJS.jnlp"} ;
    deployJava.runApplet(attributes, parameters, "1.6");
  </script>

  <!-- <applet codebase="./jars" archive="FirstApplet.jar" Code="acid.appletToJS.class" width=200    Height=100></applet> -->

<p id="summary"/>
  </body>
</html>

当我运行我的html页面时，我收到了以下错误：

 exception: Unable to load resource: http://localhost:8080/jars/FirstApplet.jar.

的http：//本地主机：8080 /瓶/ FirstApplet.jar

我真的不明白地狱“/罐子”来自???
我的项目名称是“DaaS”，我的jar，html页面和jnlp页面位于同一目录中。我正在tomcat-7服务器上运行我的html页面。

获取JNLP错误：“异常：无法加载资源：...”
