应用jtidy的问题，高手请进
请问应用jtidy为什么一直出错？程序如下：
import java.net.URL;
import java.io.*;
import org.w3c.tidy.Tidy;

public class TestHTML2XML {
private String url;
private String outFileName;
private String errOutFileName;

public TestHTML2XML(String url, String outFileName, String errOutFileName) {
this.url = url;
this.outFileName = outFileName;
this.errOutFileName = errOutFileName;
}

public void convert() {
URL u;
BufferedInputStream in;
FileOutputStream out;

Tidy tidy = new Tidy();

//Tell Tidy to convert HTML to XML
tidy.setXmlOut(true);

try {
//Set file for error messages
tidy.setErrout(new PrintWriter(new FileWriter(errOutFileName), true));
u = new URL(url);

//Create input and output streams
in = new BufferedInputStream(u.openStream());
out = new FileOutputStream(outFileName);

//Convert files
tidy.parse(in, out);

//Clean up
in.close();
out.close();

} catch (IOException e) {
System.out.println(this.toString() + e.toString());
}
}

public static void main(String[] args) {
/*
* Parameters are:
* URL of HTML file
* Filename of output file
* Filename of error file
*/
TestHTML2XML t = new TestHTML2XML(args[0], args[1], args[2]);
t.convert();
}
}
编译没有问题，但是一运行就报错，
E:\> java TestHTML2XML E:\testhtml\test.html E:\testhtml E:\testhtml
TestHTML2XML@b6ece5java.io.FileNotFoundException: E:\testhtml (拒绝访问。)
请问高手如何解决？

[解决办法]
E:\> java TestHTML2XML E:\\testhtml\\test.html E:\\testhtml E:\\testhtml这样试试
