关于JAVA中的jacob的问题

docs 这个变量时Object类型的

Dispatch.invoke()第一个参数需要Dispatch类型的

把docs和doc都申明为Dispatch类型的，或者强制转化。

你不用IDE工具的吗？用eclipse的话这段话都有错误提示的，一看就知道了。

如何利用Java-JACOB操作WORD文档

1. 初始化com的线程，非常重要，否则第二次创建com对象的时候会出现can’t co-create object异常 （参见jacob的帮助文档），完成操作com组件后要调用 realease方法

ComThread.InitSTA();// 初始化com的线程，非常重要！！使用结束后要调用 realease方法

2. 初始化word应用程序，新建一个空白文档，取得文档内容对象//Instantiate objWord //Declare word object

ActiveXComponent objWord = new ActiveXComponent("Word.Application");

//Assign a local word object

Dispatch wordObject = (Dispatch) objWord.getObject();

//Create a Dispatch Parameter to show the document that is opened

Dispatch.put((Dispatch) wordObject, "Visible", new Variant(true));// new Variant(true)表示word应用程序可见

Tip:设置一个对象的属性的时候，利用Dispatch的put方法，给属性赋值。上面这行语句相当于vb的 wordObject.Visible = true 语句

//Instantiate the Documents Property

Dispatch documents = objWord.getProperty("Documents").toDispatch(); //documents表示word的所有文档窗口，（word是多文档应用程序）

//Add a new word document, Current Active Document

Dispatch document = Dispatch.call(documents, "Add").toDispatch(); // 使用Add命令创建一个新文档，用Open命令可以打开一个现有文档

Tip:调用一个对象的方法的时候，利用Dispatch的call方法，上面的语句相当于vb的document = documents.Add() 语句。

Dispatch wordContent = Dispatch.get(document, "Content").toDispatch(); // 取得word文件的内容

Tip:取得一个对象的成员变量（属性）时利用Dispatch的get方法，上面的语句相当于vb的wordContent = document.Content语句

3. 取得word文档的内容后，可以对其内容进行操作

Dispatch.call(wordContent, "InsertAfter", "这里是一个段落的内容");//插入一个段落

4. 设置刚插入的段落的文字格式

Dispatch paragraphs = Dispatch.get(wordContent, "Paragraphs").toDispatch(); // 所有段落

int paragraphCount = Dispatch.get(paragraphs, "Count").toInt(); // 一共的段落数

// 找到刚输入的段落，设置格式

Dispatch lastParagraph = Dispatch.call(paragraphs, "Item",

new Variant(paragraphCount)).

toDispatch(); // 最后一段

Dispatch lastParagraphRange = Dispatch.get(lastParagraph, "Range").

toDispatch();

Dispatch font = Dispatch.get(lastParagraphRange, "Font").toDispatch();

Dispatch.put(font, "Bold", new Variant(true)); // 设置为黑体

Dispatch.put(font, "Italic", new Variant(true)); // 设置为斜体

Dispatch.put(font, "Name", new Variant("宋体")); //

Dispatch.put(font, "Size", new Variant(12)); //小四

注意：如果想插入一个新的空白行，也需要设置段落的文字格式，否则新插入行的文字格式会于刚插入的段落的格式相同。

5. 将当前文档保存

Dispatch.call(document, "SaveAs", new Variant("C:

abc.doc")); // 保存一个新文档

6. 释放COM线程

ComThread.Release();//释放com线程。根据jacob的帮助文档，com的线程回收不由java的垃圾回收器处理

完整测试代码：（StudyJacob.java 附件中有本文章和java源文件）

import com.jacob.activeX.ActiveXComponent;

import com.jacob.com.Dispatch;

import com.jacob.com.Variant;

import com.jacob.com.ComThread;

public class StudyJacob {

public static void main(String[] args) {

ComThread.InitSTA();// 初始化com的线程，非常重要！！使用结束后要调用 realease方法

//Instantiate objWord //Declare word object

ActiveXComponent objWord = new ActiveXComponent("Word.Application");

//Assign a local word object

Dispatch wordObject = (Dispatch) objWord.getObject();

//Create a Dispatch Parameter to show the document that is opened

Dispatch.put((Dispatch) wordObject, "Visible", new Variant(true));// new Variant(true)表示word应用程序可见

//Instantiate the Documents Property

Dispatch documents = objWord.getProperty("Documents").toDispatch(); //documents表示word的所有文档窗口，（word是多文档应用程序）

//Add a new word document, Current Active Document

Dispatch document = Dispatch.call(documents, "Add").toDispatch(); // 使用Add命令创建一个新文档，用Open命令可以打开一个现有文档

Dispatch wordContent = Dispatch.get(document, "Content").toDispatch(); // 取得word文件的内容

Dispatch.call(wordContent, "InsertAfter", "这里是一个段落的内容");//插入一个段落

Dispatch paragraphs = Dispatch.get(wordContent, "Paragraphs").toDispatch(); // 所有段落

int paragraphCount = Dispatch.get(paragraphs, "Count").toInt(); // 一共的段落数

// 找到刚输入的段落，设置格式

Dispatch lastParagraph = Dispatch.call(paragraphs, "Item",

new Variant(paragraphCount)).

toDispatch(); // 最后一段

Dispatch lastParagraphRange = Dispatch.get(lastParagraph, "Range").

toDispatch();

Dispatch font = Dispatch.get(lastParagraphRange, "Font").toDispatch();

Dispatch.put(font, "Bold", new Variant(true)); // 设置为黑体

Dispatch.put(font, "Italic", new Variant(true)); // 设置为斜体

Dispatch.put(font, "Name", new Variant("宋体")); //

Dispatch.put(font, "Size", new Variant(12)); //小四

Dispatch.call(document, "SaveAs", new Variant("C:

abc.doc")); // 保存一个新文档

ComThread.Release();//释放com线程。根据jacob的帮助文档，com的线程回收不由java的垃圾回收器处理

}

}

java中使用jacob怎么读取word里的部分内容，以字符串形式返回

FileInputStream in = new FileInputStream("D://22.doc ");

WordExtractor extractor = new WordExtractor();

String str = extractor.extractText(in);

int start = str.indexOf("AA");

int end = str.indexOf("BB");

System.out.println(str.substring(start, end));

记得导入tm-extractors-0.4.jar 包

java用jacob操作word的问题

MSWordManager msWord_Open = new MSWordManager(false);

如果这个类是可以共用的话，可以声明为一个实例变量。不然的话，你可以选择每个按钮的监听事件里new一个这个对象

java 操作 word jacob

这是word模板替换。这样做，你先把那个word复制下来，然后在清空目标，然后在粘贴。我们用POI，jacob没用过，具体思想是这样。。
