Eclipse e4 应用程序未在 Java Web 启动中启动

Question

我编写了一个 Eclipse E4 应用程序。现在我们需要使用 Java Web Start 将其发布给用户。我在 Eclipse website 上找到了一个 "how to"。项目已正确导出（已签名并创建了 jnlp 文件）。现在，当我使用 Web Start 启动应用程序时，一切看起来都很好，直到应用程序本身需要启动。没有给出错误，也没有在 Web Start 日志中找到任何内容。

这是我们使用的 JNLP 主页：

<?xml version="1.0" encoding="UTF-8"?>
<jnlp 
    spec="1.0+" 
    codebase="http://localhost:80" 
    href="test.jnlp"> <!-- URL to the site containing the jnlp application. It should match the value used on  export. Href, the name of this file -->
  <information>
    <!-- user readable name of the application -->
    <title> Test Application </title>  
    <!-- vendor name -->
    <vendor>My company</vendor>
    <!-- vendor homepage --> 
    <homepage href="My company website" /> 
    <!-- product description -->
    <description></description> 
    <icon kind="splash" href="splash.gif"/>
  </information>

  <!--request all permissions from the application. This does not change-->
  <security>
    <all-permissions/>
  </security>

  <!-- The name of the main class to execute. This does not change-->
  <application-desc main-class="org.eclipse.equinox.launcher.WebStartMain">
    <argument>-nosplash</argument>
  </application-desc>

  <resources>
    <!-- Reference to the launcher jar. The version segment must be updated to the version being used-->
    <jar href="plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.300.v20150602-1417.jar"/>

    <!-- Reference to all the plugins and features constituting the application -->
    <!-- Here we are referring to the wrapper feature since it transitively refers to all the other plug-ins  necessary -->
    <extension 
        name="Wrapper feature"
        href="features/CR_IT_Client_Feature_1.0.0.201608230817.jnlp"/>

    <!-- Information usually specified in the config.ini -->

    <!-- The id of the product to run, like found in the overview page of the product editor -->
    <property 
        name="eclipse.product" 
        value="CR-IT System Platform.product"/>
  </resources>

  <!-- Indicate on a platform basis which JRE to use --> 
  <resources os="Mac">
    <j2se version="1.5+" java-vm-args="-XstartOnFirstThread"/>
  </resources>
  <resources os="Windows">
    <j2se version="1.4+"/>
  </resources>
  <resources os="Linux">
    <j2se version="1.4+"/>
  </resources>
</jnlp>

我做了一些研究，确实找到了 web 启动的日志文件。在日志中，您可以找到错误："Missing Permissions manifest attribute in main jar: http://localhost:80/plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar"。我的清单文件如下所示：

有人知道这个奇怪问题的解决方案吗？

Answer 1

更改了 jar 中的 manefest 文件。这是通过做 jar -ufm

我添加的更改是：权限：所有权限

Codebase: *
Application-Name: <<App name>>
Trusted-Only: true
Trusted-Library: true
