使用 JNLP 文件启动应用程序
我有一个 jsp 页面为：
<html>
<head>
<title>Try in JNLP</title>
<script src="http://www.java.com/js/deployJava.js"></script>
<script>
var dir = location.href.substring(0, location.href.lastIndexOf('/')+1);
var url = dir + "try.jnlp";
deployJava.createWebStartLaunchButton(url, '1.6.0');
</script>
<noscript>JavaScript is required for this page.</noscript>
</head>
<body>
</body>
</html>
并有一个 jnlp 文件为：
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="http://localhost:8080/try/" href="try.jnlp">
<information>
<title>TRY JNLP</title>
<vendor>TRY JNLP</vendor>
</information>
<resources>
<!-- Application Resources -->
<jar href="TryJNLP.jar" main="true" />
</resources>
<application-desc name="Try JNLP" main-class="tryjnlp.TRYJNLPApp">
</application-desc>
<update check="background"/>
</jnlp>
所有 jar 都在各自的目录中，但是当我双击 jnlp 文件时，它向我显示一个错误：
java.lang.NoClassDefFoundError: org/jdesktop/application/SingleFrameApplication
及其完整的错误堆栈。
就好像我只是通过双击来运行我的 swing 应用程序（TryJNLP.jar）一样，它运行得很好。
请帮我。

and have a jnlp file as :
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="http://localhost:8080/try/" href="try.jnlp">
<information>
<title>TRY JNLP</title>

</resources>
<application-desc name="Try JNLP" main-class="tryjnlp.TRYJNLPApp">
</application-desc>
<update check="background"/>
</jnlp>
All jars are in their respective directories but when I double click the jnlp file it shows me an error saying :
java.lang.NoClassDefFoundError: org/jdesktop/application/SingleFrameApplication
with the its full error stack.
where as if I simply runs my swing application(TryJNLP.jar) by double clicking, it runs perfectly.
Please help me.

由于此代码似乎依赖于 JSR 296，因此需要将
ApplicationFramework-.jar 添加到应用程序的运行时类路径（在JNLP）。Since this code seems to depend on JSR 296, it will be necessary to add the:
ApplicationFramework-<version>.jarto the run-time class-path of the application (in the resources section of the JNLP).
