标题Re: [问题] Java Web Start 执行 Java 视窗程式的问题
时间Mon Dec 20 13:21:52 2010
※ 引述《linus (天使不见了)》之铭言：
: 请教一下, 我写了一个 JFrame 的Java视窗程式,
: 已封装成 jar档,
: 看一本书上说写一个 .jnlp档案,放在tomcat的web执行目录下,
: 建立一个html档去开启.jnlp,
: jnlp档的内容指定要执行的jar档,
: 我把.jar,.jnlp还有那个html都放在同一个web根目录下,
: 开启html档点那个jnlp的连结後确实启动了java web start,
: 但是却出现错误, "无法启动应用程式"
: 当中有发现有例外讯息,
: java.lang.ClassNotFoundException: TestWindowWs
: at java.net.URLClassLoader$1.run(Unknown Source)
: at java.security.AccessController.doPrivileged(Native Method)
: at java.net.URLClassLoader.findClass(Unknown Source)
: at com.sun.jnlp.JNLPClassLoader.findClass(Unknown Source)
: at java.lang.ClassLoader.loadClass(Unknown Source)
: at java.lang.ClassLoader.loadClass(Unknown Source)
: at com.sun.javaws.Launcher.doLaunchApp(Unknown Source)
: at com.sun.javaws.Launcher.run(Unknown Source)
: at java.lang.Thread.run(Unknown Source)
: 这是为什麽呢?
: 我直接用 java -jar 的指令可以执行那一个 .jar档,
: 可是用这种方式就失败了,
: 我把那本书的范例(透过jnlp呼叫.jar)copy到网页根目录去执行也都成功,
: 我以为是我的class没有import java.net 和 com.sun的内容,
: 但是把范例的java档打开看也没有import java.net 和 com.sun 的东西,
: 还请高手指点一下迷津, 谢谢. Orz
: 附上 jnlp档内容...Test04.jar 的main class 是 TestWindowWs
: <?xml version="1.0" encoding="UTF-8"?>
: <!-- JNLP File for Application -->
: <jnlp
: spec="1.0+"
: codebase="http://localhost:8080/JavaWebStart"
: href="JNLPTest.jnlp">
: <information>
: <title>JNLP Test</title>
: <vendor>Linus Li</vendor>
: <description>JNLP Test</description>
: <description kind="short">JNLP Test</description>
: <offline-allowed/>
: </information>
: <resources>
: <j2se version="1.6.0+"/>
: <jar href="Test04.jar"/>
: </resources>
: <application-desc main-class="TestWindowWs"/>
: </jnlp>
继耍笨的问题解决之後,
新的问题产生....
call web service的时候发生以下错误....

... 50 more
多到爆炸....不过绝大部分是因为call service 写在按钮的事件里...
所以才这麽多吧?
我想问的是, 直接执行.jar档就不会发生这些错误,
透过java web start去执行就会这样....??
问题在哪里??
请高手指点....谢谢.
