能否编程对其他JAVA窗口应用程序中的控件进行操作

不可以，最多只能在当窗口获得焦点的时候通过后台程序模拟键盘和鼠标操作。操作控件是不可以的

java web项目调用ocx控件

是的，ocx插件就是必须每台使用的电脑都必须安装ocx插件，所以你需要提供一个ocx插件的下载地址，让每个使用的用户下载这个插件；而且ocx插件的局限性不仅于此，ocx插件对浏览器也有限制，比如：ocx插件只支持系统自带的IE低版本的浏览器，其他厂商的浏览器基本都不支持

如何设置java控件的位置和大小

把java控件所在的容器(比如:JFrame,JPanel)的布局设为空布局。(比如：jp.setLayout(null);

然后用java控件的setBounds函数设置java控件的位置和大小。(比如：JTextField jtf=new JTextField(5); jtf.setBounds(100,100,30,20);//100,100是在容器中的相对位置坐标x和坐标y

30,20是Java控件的大小，30是长，20是高。)

我给你个Java语言的例子,你看看吧。

import javax.swing.JButton;

import javax.swing.JFrame;

public class B {

 B(){

  JFrame jf=new JFrame();

  jf.setLayout(null);

  JButton jb=new JButton("确定");

  jb.setBounds(25, 20, 60, 20);

  jf.add(jb);

  jf.setSize(200,100);

  jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

  jf.setVisible(true);

 }

 public static void main(String[] args) {

  new B();

 }

}

运行结果：

JAVA怎么调用OCX控件

需要通过Jacob这个开源组件与OCX控件进行通讯，Jacob下载地址：引用相应的包后就能ActiveXComponent app = new ActiveXComponent("Word.Application");以这种方式访问ActiveX对象
