JavaWeb启动在构建JFrm时挂起

java-web-start jframe java

dacwe · 技术社区 · 14 年前

在用Java Web start启动程序时,我需要帮助。

我从主页启动我的程序,程序在进程处理程序中挂起一个javaw进程。当我使用jvisualvm转储线程时,我看到它挂在“awt-eventqueue-0”线程中(构建我的jframe时):

"AWT-EventQueue-0" prio=6 tid=0x02da7c00 nid=0x1414 runnable [0x0367f000]
    java.lang.Thread.State: RUNNABLE
        at sun.awt.windows.WToolkit.getScreenInsets(Native Method)
        at sun.awt.windows.WToolkit.getScreenInsets(Unknown Source)
        at java.awt.Window.init(Unknown Source)
        at java.awt.Window.<init>(Unknown Source)
        at java.awt.Frame.<init>(Unknown Source)
        at javax.swing.JFrame.<init>(Unknown Source)
        at se.testing.Application$2.run(Application.java:170)
        at java.awt.event.InvocationEvent.dispatch(Unknown Source)
        at java.awt.EventQueue.dispatchEvent(Unknown Source)
        at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source)
        at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source)

主要是这样的:

public static void main(String... args) {

    ....

    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            JFrame f = new JFrame("Test");
            ...
        }
    });
}

更新 :这是JNLP文件:

<?xml version="1.0" encoding="utf-8"?>
<jnlp spec="6.0+" 
      codebase="http://localhost/archive/Application-1.0.0/"
      href="application.jnlp">

    <jar href="wsdl4j-1.6.2.jar"/>
  </resources>
  <application-desc main-class="se.testing.Application">
  </application-desc>
</jnlp>

可能有什么问题?! (这是我触摸图形用户界面的第一个地方,我在Windows XP上。)

另外,我注意到我有另一个awt线程(??!?!)也悬挂在不同的地方:

从第一次跑步开始,我就把它挂在这里:

"AWT-EventQueue-1" prio=6 tid=0x03448800 nid=0x152c runnable [0x036cf000]

从运行2:

尝试设置 f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

如果有人找到另一个解决方案,我直接接受它! 我不轻视当前的解决方案…

似乎只有在使用英特尔高清图形系统(我的系统是核心i3 Clarkdale)时才会发生这种情况。

可能的解决方案已测试!:

使用Windows默认驱动程序(~vga驱动程序)
新图形卡

看起来像是图形驱动程序和Java的一些问题。

看看是否 this link to Java 2D system settings 帮助。

您试过在主线程中构建GUI吗?事件处理线程if-处理事件:-)

试试这个代码:

public static void main(String... args) {
    JFrame f = new JFrame("Test");
    f.setVisible( true );
}
