exe无法运行

Question

I used the following Java code for move the file form one directory to another, then execute the file in the destination directory. My code is

import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import java.io.IOException;

import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFileChooser;
import javax.swing.JFrame;


import org.apache.commons.io.FileUtils;
public class JFileChooserTest {
  public static void main(String[] args) {
        String filelocation="C:\\Users\\FSSD\\Desktop\\OutPut\\Target";
        File trgDir = new File(filelocation);
        System.err
                .println("file location>>>>>>>>>>>>>>>>>>>"
                        + filelocation);
        File desDir = new File(
                "C:\\Users\\FSSD\\IndigoWorkSpace\\Swing\\test");

        try {
            FileUtils.copyDirectory(trgDir, desDir);
            // FileUtils.copyDirectory(srcDir, trgDir);
        } catch (IOException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }

        Runtime rt=Runtime.getRuntime();
        try {
            Process p=rt.exec("test\\setup.exe");
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
  }
}

While i executing this code, the file was successfully moved by i execute this code i got the following error.

java.io.IOException: Cannot run program "test\setup.exe": CreateProcess error=740, The requested operation requires elevation
    at java.lang.ProcessBuilder.start(ProcessBuilder.java:460)

    ... 4 more

Here i used "setup.exe" . It is an executable file. while i execute at run time i got the above error. Why it will happens, is any possible to resolve it. Thanks in advance..

Answer 1

我猜您正在使用Windows 7，当您运行批处理过程以启动JFileChooser测试时，右键单击并选择“以管理员身份运行”。

Answer 2

The requested operation requires elevation

You do not have the rights to execute this setup. Probably UAC blocks it.

Use the runas command with Runtime#exec in Java.
