使用Eclipse来运行现有的Java Web启动应用程序 [英] Use Eclipse to run an existing Java web start application

问题描述

我可以使用Java Web Start在命令行上启动Swing GUI应用程序：
javaws http：// localhost：7001 / webstart / myapp / launch.jnlp

如何在Eclipse 3.3.2和jdk 6中运行我的应用程序Java网络启动？
我可以在Eclipse中运行我的应用程序，而不需要启动Java Web？怎么样？
单击Eclipse中的launch.jnlp文件只打开文本编辑器。

launch.jnlp文件如下：

 < jnlp spec =1.0+codebase =$$ codebasehref =$$ name> 
 
< information> 
< title> $ {com.prod.my.myapp.common.client.title}< / title>

< / resources> 
 
< application-desc main-class =com.prod.my.myapp.common.framework.applicationmainwindow.gui.myappApplication/ 
 
< / jnlp> 
  

解决方案

Java网络启动没有什么比下载jar在你的JNLP文件中并执行 main-class 确保所有引用的jar都在类路径上，属性通过 -D ... 和 max-heap-size 通过VM参数 -Xmx256m 设置。

如果您有JNLP文件中列出的jars项目作为依赖关系创建运行配置，并将您的主类指定为主班要跑您还应该添加属性来运行配置。通过添加 -Djava.naming.factory.initial = weblogic.jndi.WLInitialContextFactory 等作为命令行参数来执行此操作。

最后添加-Xmx256m作为JVM选项。

祝你好运！ ：）

I can use Java web start to start my Swing GUI application on the command line: javaws http://localhost:7001/webstart/myapp/launch.jnlp

How to run my application inside Eclipse 3.3.2 and jdk 6 with Java web start? Can I run my application inside Eclipse without Java web start? How? Clicking the launch.jnlp file inside Eclipse only open the text editor.

The launch.jnlp file is as follows:

<jnlp spec="1.0+" codebase="$$codebase" href="$$name"> 

  <information> 
    <title>${com.prod.my.myapp.common.client.title}</title> 
    <vendor>I</vendor> 
    <homepage href="http://devzone/english/dev%20template/html_templates/main.asp"/> 
    <description>${com.prod.my.myapp.common.client.description}</description> 
    <description kind="short">${com.prod.my.myapp.common.client.short_description}</description> 
    <icon href="$$context/images/chflag.jpg"/> 
  </information> 

  <security> 
      <all-permissions/> 
  </security> 

  <resources> 

  <java version="1.6.0_05" href="http://java.sun.com/products/autodl/j2se" max-heap-size="256m"/> 

    <!-- myapp Application --> 
    <jar href="myprod.myapp.client.jar"/> 
    <jar href="myprod.reports.jar"/> 

    <!-- TR Client jar --> 
    <jar href="extern.ejb-client.jar"/> 

    <property name="java.naming.factory.initial" value="weblogic.jndi.WLInitialContextFactory"/> 
    <property name="java.naming.provider.url" value="${com.prod.my.myapp.common.client.naming_provider}"/> 
    <property name="weblogic.jndi.enableServerAffinity" value="true" / 

  </resources> 

  <application-desc main-class="com.prod.my.myapp.common.framework.applicationmainwindow.gui.myappAp­plication"/ 

</jnlp> 

解决方案

Java web start does nothing more than it downloads the jars in you JNLP file and execute the main-class ensuring all the referenced jars are on the classpath, properties are set via -D... and max-heap-size is set via the VM parameter -Xmx256m.

If you have a project with the jars listed in the JNLP files as dependencies create a run configuration and specify your main-class as Main Class to be run. You should also add the properties to you run configuration. Do this by adding -Djava.naming.factory.initial=weblogic.jndi.WLInitialContextFactory etc. as command line parameter.

Finally add -Xmx256m as JVM option.

Good luck! :)
