Question

我正在尝试通过Java Web Start运行这个Java应用程序（jar），并且遇到了非常困难的时间。

这是我目前的JNLP来源：

<?xml version="1.0" encoding="utf-8"?> 
<jnlp spec="1.0+" codebase="http://localhost:8080/" href="Test.jnlp">
    <information>
        <title>Jnlp Testing</title>
        <vendor>YONG MOOK KIM</vendor>
        <homepage href="http://localhost:8080/" />
        <description>Testing Testing</description>
    </information>
    <security>
        <all-permissions/>
    </security>
    <resources>
        <j2se version="1.6+" />
        <jar href="TestJnlp.jar" />
        <jar href="lib/appframework-1.0.3.jar"/>
        <jar href="lib/junit-4.7.jar"/>
        <jar href="lib/org.eclipse.swt.win32.win32.x86_64_3.100.0.v4233d.jar"/>
        <jar href="lib/org-netbeans-modules-java-j2seproject-copylibstask.jar"/>
        <jar href="lib/sqlite-jdbc-3.7.2.jar"/>
        <jar href="lib/swing-worker-1.1.jar"/>
    </resources>
    <application-desc main-class="proteotypic.ProteotypicQuantificationApp" />
</jnlp>

运行JNLP文件后，出现以下错误：

JNLPException[category: Launch File Error : Exception: null : LaunchDesc:

我签署了除lib/org.eclipse.swt.win32.win32.x86_64_3.100.0.v4233d.jar以外的所有邮箱 - 如果我也签了那个，我会得到一个不同的例外：

在执行“javaws -viewer”并重新运行JNLP后，我得到：

Answer 1

所有jars 在一个jnlp 中需要使用相同的签名进行签名，使用带有自己的jnlp的扩展名来存放由第三方签名的jar。

有些jar使用jar中的原始签名进行加密（SQL服务器的JDBC驱动程序），其他人在重新签名时不起作用（javahelp.jar）

您还可以通过将其包含在应用程序的jnlp：

中来节省签名的麻烦

<extension name="javahelp" href="javahelp.jnlp"/>

Answer 2

您必须签署jar文件。您可以使用keytool自行完成此操作，但如果您打算部署此功能，我建议您使用Verisign或类似公司进行签名。

如果您只需要临时修复，signing it yourself进行测试就可以了。

这是一款易于使用的tutorial。

Answer 3

所有罐子必须使用相同的签名进行签名。

Java Web Start Jar签名问题？
