Question

我在网上搜索过并找不到明确的解决方案，所以请点击：

我创建了一个JNLP文件以在同一文件夹中启动JAR，但它无法启动并提供错误“无法解析启动文件。第0行出错。”

这是DevChat.jnlp：

<?xml version="1.0" encoding="utf-8"?> 
<!-- JNLP to Launch DevChat -->
<jnlp 
    spec="1.0+"
    href="DevChat.jnlp">

    <information>
        <title>DevChat</title>
        <vendor>Dev Team</vendor>
    </information>

    <security>
        <all-permissions/>
    </security>

    <resources>
    <j2se version="1.4.2"/>
        <jar href="DevSuite.jar" main="true" />
    <jar href="commons-net-3.0.1.jar" />
    </resources>

    <application-desc 
    main-class="DevChat"
        name="DevChat"
     </application-desc>

</jnlp>

例外：

JNLParseException[ Could not parse launch file. Error at line 0.]

包装的例外：

从控制台运行根本不显示任何内容。任何帮助将不胜感激！

我猜这个XML格式不正确：

<application-desc 
    main-class="DevChat"
    name="DevChat"
</application-desc>

你需要像这样关闭开放标签：

<application-desc 
    main-class="DevChat"
    name="DevChat">
</application-desc>

Jnlp无法解析启动文件。第0行出错
