我有一个通过 PHP 脚本创建的 JNLP 文件。它输出类似于以下文件的内容：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<jnlp codebase="/" spec="1.0+">

应用程序加载并最初打开正常，但是应用程序很慢且无响应，在查看我的 apache 访问日志后，似乎发生了一些奇怪的事情，首先，它成功加载了所有 jar：

请注意 /getjava/libs/lib 已更改为 /getjava/jar/lib
这是怎么回事？JVM 从哪里得到这个 URL？
更重要的是，为什么 JVM 一遍又一遍地请求同一个文件？
编辑 - 更多信息
我想我已经把问题缩小了一点。我很确定这与Netbeans有关。我正在使用版本 7.2.1。
似乎额外库请求的 URL 来自META-INF/MANIFEST.MF主应用程序 Jar 中的文件。在那里我可以看到以下内容：
Class-Path: lib/commons-codec-1.6.jar lib/commons-logging-1.1.1.jar li
b/fluent-hc-4.2.3.jar lib/httpclient-4.2.3.jar lib/httpclient-cache-4
.2.3.jar lib/httpcore-4.2.2.jar lib/httpmime-4.2.3.jar
这将解释修改后的 URL 和随后的 404 响应，因为这些文件在该 URL 上不可用。
我不明白为什么 Netbeans 会创建这些文件路径。我的印象是 Java Webstart 使用 JNLP 文件下载其资源，并且在该<resources>节点中？
我怎样才能停止 netbeans 添加这个Class-Path属性，因为我相信这是我的问题的根源。
进一步更新
我通过破解文件找到了解决此问题的方法。如果我取出这条线：
<attribute name="Class-Path" value="${jar.classpath}"/>
从这个文件：
nbproject\build-impl.xml
然后 Netbeans 为 Webstart 应用程序正确编译 Jar。它不会在 Jar 内的文件中创建Class-Path属性。META-INF/MANIFEST.MF删除此应用程序后，该应用程序工作得非常好，没有挂起，也没有对不存在的文件的虚假请求。
现在我想问题是，Netbeans 为什么要这样做？是否有适当的解决方法，而不是我破解 XML 配置文件？请记住，我已经使用 Java 大约一周了。我真的对 ANT/Java 一无所知。
