OCX内嵌

我这里用的是SWT/JFace开发application，SWT自带的org.eclipse.swt.ole.win32 包可以支

持内嵌OLE和ActiveX。
具体用法如下：
//创建一个OleFrame做为OLE（或ActiveX）的框架
OleFrame oleFrame = new OleFrame(this, SWT.NONE);
//创建ActiveX的容器，其中的classID是ActiveX的claid,在注册表中可以找到
OleControlSite oleControl = new OleControlSite(oleFrame, SWT.NONE, “classID”);
//OleAutomation类用来执行ActiveX中的方法
OleAutomation oleAutomation = new OleAutomation(oleControl);
//将ActiveX显示在application中
oleControl.doVerb(OLE.OLEIVERB_SHOW);

调用AcitveX中方法的具体过程：
1、不带参数的方法调用
//获取Method Name的ID，Method Name为ActiveX中具体的方法名
int[] regspid = oleAutomation.getIDsOfNames(new String[] { "Method Name" });
int dispIdMember = regspid[0];
//方法调用
oleAutomation.invoke(dispIdMember);

2、带参数的方法调用
//获取Method Name的ID，Method Name为ActiveX中具体的方法名
int[] regspid = oleAutomation.getIDsOfNames(new String[] { "Method Name" });
int dispIdMember = regspid[0];
//设置方法的具体参数。Variant数组的长度为Method Name方法参数的个数
//假设有四个参数
Variant[] rgvarg = new Variant[4];
rgvarg[0] = new Variant(fileID);
rgvarg[1] = new Variant(itdsURL);
rgvarg[2] = new Variant(idType);
rgvarg[3] = new Variant(reportURL);
//方法调用
oleAutomation.invoke(dispIdMember, rgvarg);


调用OLE Exemple：Java程序内嵌Word应用程序

package geftest.swt;

import java.io.File;

import org.eclipse.swt.SWT;
import org.eclipse.swt.graphics.Point;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.ole.win32.OLE;
import org.eclipse.swt.ole.win32.OleClientSite;
import org.eclipse.swt.ole.win32.OleFrame;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Composite;
public class ActiveXTest
{

private Shell sShell = null;
private Button button = null;
private OleClientSite clientSite;
public static void main(String[] args)
{

Display display = Display.getDefault();
ActiveXTest thisClass = new ActiveXTest();
thisClass.createSShell();
thisClass.sShell.open();

while (!thisClass.sShell.isDisposed())
{
   if (!display.readAndDispatch())
    display.sleep();
}
display.dispose();
}

/**
* This method initializes sShell
*/
private void createSShell()
{
GridData gridData = new GridData();
gridData.horizontalSpan = 2;
GridLayout gridLayout = new GridLayout();
gridLayout.numColumns = 3;
sShell = new Shell();
sShell.setText("Shell");
sShell.setLayout(gridLayout);
sShell.setSize(new Point(800, 600));
OleFrame frame = new OleFrame(sShell, SWT.NONE);
button = new Button(sShell, SWT.NONE);
button.setLayoutData(gridData);
button.setText("Save");
button.addSelectionListener(new org.eclipse.swt.events.SelectionAdapter() {
   public void widgetSelected(org.eclipse.swt.events.SelectionEvent e)
   {
    clientSite.save(new File("d:/test.docx"),true);
   }
});
frame.setSize(800,600);
clientSite = new OleClientSite(frame, SWT.NONE,"Word.Document.8");
clientSite.setSize(400,400);
clientSite.doVerb(OLE.OLEIVERB_SHOW);
}

}

  请问OCX回调的方法要怎么处理
