用jacob时错误。

[dylsz]

在网上找了这样一个程序：
import java.io.File;
import com.jacob.com.*;
import com.jacob.activeX.*;
/**
* Title: pdf extraction
* Description: email:[e-mail]
* Copyright: Matrix Copyright (c) 2003
* Company: Matrix.org.cn
* @author chris
* @version 1.0,who use this example pls remain the declare
*/
public class FileExtracter{
public static void main(String[] args) {
ActiveXComponent component = new ActiveXComponent("Word.Application");
String inFile = "c:\\test.doc";
String tpFile = "c:\\temp.htm";
String otFile = "c:\\temp.xml";
boolean flag = false;
try {
component.setProperty("Visible", new Variant(false));
Object wordacc = component.getProperty("document．").toDispatch();
Object wordfile = Dispatch.invoke(wordacc,"Open", Dispatch.Method,
new Object[]{inFile,new Variant(false), new Variant(true)},
new int[1] ).toDispatch();
Dispatch.invoke(wordfile,"SaveAs", Dispatch.Method, new Object[]{tpFile,new Variant(8)}, new int[1]);
Variant f = new Variant(false);
Dispatch.call(wordfile, "Close", f);
flag = true;
} catch (Exception e) {
e.printStackTrace();
} finally {
component.invoke("Quit", new Variant[] {});
}
}
}

编译时发生下面这样的错误：
F:\java>javac Test.java

F:\java>java Test
Exception in thread "main" java.lang.UnsatisfiedLinkError: no jacob in java.libr

请问这是怎么回事？

你加载jacob包了么

[dylsz]

加了阿.

[zmybest]

你的jacob包放到哪个目录里了？是否设置了jacob包的classpath

[疯癫行者]

运行时应该这样：
F:\java>java -Djava.library.path=somepath Test
其中somepath替换成，jacob所在的目录。

[疯癫行者]

不好意思，更正一下:
其中somepath替换成，jacob.dll所在的目录。

[tonee]

jacob.dll放到你设置的环境变量的path指定的任何一个目录下就可以了

1.加载JACOB的包
2.把JACOB.DLL放到系统目录下面（比如C:\WINDOWS\SYSTEM32\目录下面）
