Question

我正在尝试在firefox上的网页中查看.doc / .docx微软word文件。当所有失败时，我尝试创建一个applet，它将包含一个Word OLE实例来查看文档。

我使用：org.eclipse.swt.ole.win32.OleClientSite创建了applet，并且在eclipse中它工作正常，我可以在里面看到Word。

我创建了一个.jar文件，我试图在firefox的网页中使用applet。小程序启动但我看不到任何内容。

这是我的applet代码：

import java.applet.Applet;
public class JWordViewer  extends Applet {
  org.eclipse.swt.widgets.Display display;
  org.eclipse.swt.widgets.Shell swtParent;
  java.awt.Canvas awtParent;

  public void init() {
    Thread thread = new Thread(new Runnable() {
      public void run() {
        setLayout(new java.awt.GridLayout(1, 1));
        awtParent = new java.awt.Canvas();
        add(awtParent);
        display = new org.eclipse.swt.widgets.Display();
        swtParent = org.eclipse.swt.awt.SWT_AWT.new_Shell(display,
            awtParent);
        swtParent.setLayout(new org.eclipse.swt.layout.FillLayout());
        org.eclipse.swt.ole.win32.OleFrame frame = new org.eclipse.swt.ole.win32.OleFrame(
            swtParent, org.eclipse.swt.SWT.NONE);
        org.eclipse.swt.ole.win32.OleClientSite site;
        try {
          site = new org.eclipse.swt.ole.win32.OleClientSite(frame,
              org.eclipse.swt.SWT.NONE, "Word.Document");

        } catch (org.eclipse.swt.SWTException e) {
          String str = "Create OleClientSite Error" + e.toString();
          System.out.println(str);
          return;
        }
        setSize(500, 500);
        validate();
        site.doVerb(org.eclipse.swt.ole.win32.OLE.OLEIVERB_SHOW);

        while (swtParent != null && !swtParent.isDisposed()) {
          if (!display.readAndDispatch())
            display.sleep();
        }
      }
    });
    thread.start();
  }

  public void stop() {
    if (display != null && !display.isDisposed()) {
      display.syncExec(new Runnable() {
        public void run() {
          if (swtParent != null && !swtParent.isDisposed())
            swtParent.dispose();
          swtParent = null;
          display.dispose();
          display = null;
        }
      });
      remove(awtParent);
      awtParent = null;
    }
  }
}

`

知道为什么不起作用？

这是Java控制台所说的内容：

basic: Told clients applet is started Exception in thread "Thread-11" java.lang.ExceptionInInitializerError at org.eclipse.swt.widgets.Display.<clinit>(Display.java:130) at JWordViewer$1.run(JWordViewer.java:17) at java.lang.Thread.run(Unknown Source) Caused by: java.security.AccessControlException: access denied (java.util.PropertyPermission sun.arch.data.model read) at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPropertyAccess(Unknown Source) at java.lang.System.getProperty(Unknown Source) at org.eclipse.swt.internal.Library.loadLibrary(Library.java:167) at org.eclipse.swt.internal.Library.loadLibrary(Library.java:151) at org.eclipse.swt.internal.C.<clinit>(C.java:21) ... 3 more

在我告诉它相信这个小程序之后......

Answer 1

答案是：它需要在光盘上读取和执行的权限。一种选择是签署.jar文件。另一种选择是授予光盘权限。

我用于测试第二个选项：我修改了java.policy文件： ` grant codeBase“http://localhost/-”{ permission java.io.FilePermission“＆lt;＆gt;”，“读，写，执行，删除”; 权限java.net.SocketPermission“”，“接受，连接，听，解决”; permission java.util.PropertyPermission“”，“读，写”; permission java.lang.RuntimePermission“*”; permission java.awt.AWTPermission“showWindowWithoutWarningBanner”; };

这就解决了。
