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。我找到了一个＆＃34;如何＆＃34;在Eclipse website上。项目已正确导出（已创建签名和jnlp文件）。现在，当我使用Web Start启动应用程序时，一切都看起来很好，直到应用程序本身需要启动。没有给出错误，也无法在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，确实发现了一个web start的日志文件。在日志中，您可以在主jar中找到错误：＆＃34; Missing Permissions清单属性：http://localhost:80/plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar＆＃34;。我的清单文件如下：

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

我添加的更改包括：权限：所有权限

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