---------------------------------------------------------------------------------------------------

1. 新建 OleView:

package hellorcp.ole;

import org.eclipse.jface.action.IMenuManager;
import org.eclipse.jface.action.IToolBarManager;
import org.eclipse.swt.SWT;
import org.eclipse.swt.ole.win32.OleFrame;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.ui.part.ViewPart;

public class OleView extends ViewPart {
	public OleFrame frame;

	public static final String ID = "hellorcp.view.OleView"; //$NON-NLS-1$

	/**
	 * Create contents of the view part
	 * 
	 * @param parent
	 */
	@Override
	public void createPartControl(Composite parent) {
		// 创建OleFrame对象
		frame = new OleFrame(parent, SWT.NONE);

		//
		createActions();
		initializeToolBar();
		initializeMenu();
	}

	/**
	 * Create the actions
	 */
	private void createActions() {
		// Create the actions
	}

	/**
	 * Initialize the toolbar
	 */
	private void initializeToolBar() {
		IToolBarManager toolbarManager = getViewSite().getActionBars()
				.getToolBarManager();
	}

	/**
	 * Initialize the menu
	 */
	private void initializeMenu() {
		IMenuManager menuManager = getViewSite().getActionBars()
				.getMenuManager();
	}

	@Override
	public void setFocus() {
		// Set the focus
	}

}

2. 新建 OpenFileAction:

package hellorcp.ole;

import org.eclipse.jface.action.IAction;
import org.eclipse.jface.viewers.ISelection;
import org.eclipse.swt.SWT;
import org.eclipse.swt.ole.win32.OLE;
import org.eclipse.swt.ole.win32.OleAutomation;
import org.eclipse.swt.ole.win32.OleClientSite;
import org.eclipse.swt.ole.win32.Variant;
import org.eclipse.ui.IViewPart;
import org.eclipse.ui.IViewReference;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.IWorkbenchWindowActionDelegate;

public class OpenFileAction implements IWorkbenchWindowActionDelegate {
	IWorkbenchWindow window;

	public void dispose() {
		// TODO 自动生成方法存根
	}

	public void init(IWorkbenchWindow window) {
		this.window = window;
	}

	public void run(IAction action) {
		IViewReference[] vfs = window.getActivePage().getViewReferences();
		IViewPart vw;
		for (int i = 0; i < vfs.length; i++) {
			vw = vfs[i].getView(false);
			if (vw.getTitle().equals("使用Active X控件")) {
				OleClientSite client = new OleClientSite(((OleView) vw).frame,
						SWT.NONE, "Shell.Explorer.2");
				client.doVerb(OLE.OLEIVERB_SHOW);
				OleAutomation oa = new OleAutomation(client);
				Variant str = new Variant("http://www.iteye.com/");
				oa.invoke(104, new Variant[] { str });
			}
		}
	}

	public void selectionChanged(IAction action, ISelection selection) {
		// TODO 自动生成方法存根
	}

}

3. 修改 Perspective.java, 修改后：

package hellorcp;

import org.eclipse.ui.IPageLayout;
import org.eclipse.ui.IPerspectiveFactory;

public class Perspective implements IPerspectiveFactory {

	public void createInitialLayout(IPageLayout layout) {
		// FirstView
		String editorArea = layout.getEditorArea();
//		layout.addView("hellorcp.view.FirstView", IPageLayout.RIGHT, 0.2f,
//				editorArea);

		// SecondView
//		layout.setEditorAreaVisible(false);
//		layout.addView("hellorcp.view.SecondView", IPageLayout.RIGHT, 0.5f,
//				editorArea);
		
		// OleView
		layout.addView("hellorcp.ole.OleView", IPageLayout.RIGHT, 0.5f,
				editorArea);
	}

}

4. 配置 plugin.xml:

1) action 配置片段：

          	<action
				class ="hellorcp.ole.OpenFileAction" 
             	icon ="icons/alt_window_16.gif" 
             	id ="hellorcp.ole.OpenFileAction" 
          	    label ="Ole菜单项" 
				menubarPath ="hellorcp.firstmenu/additions" 
              	style ="push" 
                toolbarPath ="additions" 
               	tooltip ="Ole菜单项" />

2) view 配置片段：

         <view
         	class="hellorcp.ole.OleView"
         	id="hellorcp.ole.OleView"
         	name="使用Active X控件" />

5. 保存，运行（点击工具类第1个图标），效果如下：
