java – JNLP,Webstart和Maven

前端之家收集整理的这篇文章主要介绍了java – JNLP,Webstart和Maven前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我创建了一个简单的Hello World Swing应用程序,它可以在 Eclipse中编译和运行.我现在正在尝试将此应用程序转移到Maven包结构并将其作为Java Web-Start应用程序运行,这让我感到非常痛苦.运行“mvn clean install”后,javaws似乎加载了几秒钟然后退出.

以下是一些可供参考的内容.我(非常简单)的项目应该是完全可重现的:

谢谢.

PS:我正在使用的项目来自Shaun Abram的网站上的一个例子,这里是:http://www.shaunabram.com/swing-webstart-maven-example/.它被设计为与tomcat接口并在服务器上运行但我觉得我应该能够让它在本地工作.我只是使用SwingWebstartMaven-Client分支并忽略SwingWebstartMaven-Web分支.

PPS:我觉得我应该可以重命名包结构,但由于某种原因我不能.每当我尝试用目录结构中的姓氏替换shaunabram,我的java文件和pom.xml文件中的包声明时,它会抱怨:

[ERROR]   The project com.kothur.swingwebstartmaven:SwingWebstartMaven-Client:1.0 (/media/reivei/New Volume/Project Files/SwingWebstartMaven/SwingWebstartMaven-Client/pom.xml) has 1 error
[ERROR]     Non-resolvable parent POM: Failure to find com.kothur.swingwebstartmaven:SwingWebstartMaven:pom:1.0 in http://repo.maven.apache.org/maven2 was cached in the local repository,resolution will not be reattempted until the update interval of central has elapsed or updates are forced and 'parent.relativePath' points at wrong local POM @ line 6,column 13 -> [Help 2]

编辑:问题与这个问题相同:I am not able launch JNLP applications using “Java Web Start”?除了在Ubuntu机器上.我很难理解作者的解决方案将如何转换为Ubuntu(我尝试将JAVAWS_HOME设置为我的jre bin并重新运行javaws但它给了我同样的问题(即Java 6启动画面启动然后停止,没有程序是发现)).双击launch.jnlp在Java 7中运行它(不是我想要的)并吐出

"Error: Unable to load resource: http://localhost:8080/SwingWebstartMaven-Web/webstart/launch.jnlp."

在那之后,我尝试了其他一些事情.主要的pom.xml有tomcat插件,我没有使用它,所以我尝试删除它,它没有做任何事情.然后我尝试创建一个tomcat服务器并将项目文件夹放在/ var / lib / tomcat7 / webapps /中.这也不会改变错误.

解决方法

阅读Web Start的实际内容;它是一种读取描述符(例如,填充的template.vm)并从中下载并启动常规Java应用程序(与applet相对)的机制.如果你从命令行运行并且已经有了jar,那就多余了.如果你真的想玩它,你需要将template.vm编辑成指向本地代码库的 a valid JNLP descriptor file,然后使用javaws heet.jnlp.请参阅javaws的手册页及其包含的链接.

至于你的Maven问题,你似乎没有安装引用的父POM,因此Maven不知道从哪个继承.您需要在父POM上执行相同的更改,安装,然后处理子POM.
