很抱歉这篇文章很长,但我想彻底解决这个问题。其他人已经提出了这个问题,但我相信我遵循了所有发现的here指令,并阅读了已经提出的所有其他问题。下面是jnlp文件内容和html文件(没有真实地址),后面是异常和包装器异常(我确实得到了最新版本的java并验证了它的工作原理)。我是一个相对较新的JNLP和webstart,所以我不确定所有东西是如何组合在一起的。
JNLP内容:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<jnlp codebase = "http://example.com/index.html" href="launch.jnlp" spec="1.0+">
<information>
<title>Online Time Clock</title>
<vendor>Kevin</vendor>
<homepage href="www.google.com"/>
<description>Online Time Clock</description>
<description kind="short">Online Time Clock</description>
</information>
<update check="always"/>
<resources>
<j2se version="1.8+"/>
<jar eager="true" href="Online_Time_Clock.jar" main="true"/>
</resources>
<application-desc main-class="online.time.clock.forms.form">
</application-desc>
</jnlp>
HTML内容:
head>
<meta charset="utf-8">
<title>Homepage</title>
<style type="text/css">
@import url("indexcss.css");
#Container2 {

}
</style>
</head>

答案 0 :(得分:1)
在你的jnlp文件中,代码库是“http://example.com/index.html”,但代码库必须是目录,而不是文件。相反,你应该有这样的东西:
<jnlp codebase = "http://example.com/" href="launch.jnlp" spec="1.0+">
以上假设你的jnlp在这里:http://example.com/launch.jnlp
