这是我第一次使用Java Web Start。这是我的应用程序的演示版本。我已将JAR上传到我的服务器,并创建了一个JNLP文件。当我在本地运行文件时,我得到如下所示的异常。

This是我正在阅读的参考,下面是我的JNLP文件。

DerbyPro.jnlp

<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="" href="">
    <information>
        <title>Derby Pro</title>
        <vendor>Neon Orb</vendor>
        <icon href="http://neonorb.com/images/derby-pro/derby-pro-icon-hd.png"/>
        <offline-allowed/>
    </information>

    <resources>
        <j2se version="1.8+" href=
                "http://neonorb.com"/>
        <jar href="http://neonorb.com/clientportal/derby-pro-demo.jar"
             main="true" />
    </resources>

    <application-desc
            name="Derby Pro"
            main-class="com.neonorb.derbypro.main.DerbyPro"
            width="300"
            height="300">
    </application-desc>

    <update check="background"/>
</jnlp>

这是我的build.gradle文件,如下所示:./gradlew -Pversion=0.0.0 -Pdemo=true fatJar

    outfile = 'DerbyPro.exe'

    companyName = 'Neon Orb'
    productName = 'Derby Pro'
}

//OS X

    bundleJRE = true
    javaProperties.put("apple.laf.useScreenMenuBar", "true")

这是清单目录。

这是明确的内容。

您的jar文件包含重复的条目,这些条目在部署时可能会导致问题。如果对jar文件运行以下命令,则会看到重复的条目:

$ unzip -l derby-pro-demo.jar |grep META
        0  01-26-16 11:47   META-INF/
      116  01-26-16 11:47   META-INF/MANIFEST.MF
      321  06-09-15 18:42   META-INF/LICENSE
      825  06-09-15 18:42   META-INF/NOTICE
...
    11358  06-14-15 12:06   META-INF/LICENSE.txt
      172  06-14-15 12:06   META-INF/NOTICE.txt
...
    11358  04-03-15 14:30   META-INF/LICENSE.txt
      301  04-03-15 14:30   META-INF/NOTICE.txt

问题是由fatJar引起的。请参阅herehere

创建胖罐时,应解决重复的条目。我对gradle没有经验。问题(第一个链接)仍然标记为“打开”,所以我假设可能没有一个简单的修复。作为一种解决方法(如果这可能并且适合您),我可以想象将所有jar内容首先复制到临时目录。这将覆盖重复的条目。然后你可以从临时目录中构建fat jar。但是,我会非常小心。首先,一些重复的类文件可能是相关的,其次是LICENSE,NOTICE等文件肯定会导致许可证问题。

JNLP文件包含一个主类属性,Java Web Start正在尝试使用该主类创建清单。因此,从JNLP文件中删除主类属性允许它运行。
