我正在尝试从 java 应用程序运行 .exe,但收到以下错误消息:
Java Virtual Machine Launcher(title) 发生 Java 异常。
我努力了:
try {
Runtime rt = Runtime.getRuntime();
Process p = rt.exec("C:\\PathToExe\\MyExe.exe");
InputStream in = p.getInputStream();
OutputStream out = p.getOutputStream();
InputStream err = p.getErrorStream();
} catch (Exception exc) {}
和:
try {
Process process = new ProcessBuilder("C:\\PathToExe\\MyExe.exe").start();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
}
} catch (IOException ex) {
Logger.getLogger(ScannerUI.class.getName()).log(Level.SEVERE, null, ex);
}
当我尝试运行像 uTorrent 这样的其他东西时,它们都可以工作,但是当我尝试运行我必须运行的 .exe 时它会失败。
此外,这个 .exe 在一个文件夹中,如果我尝试单独运行这个 .exe(在它的文件夹之外),它会返回相同的错误消息。
我不认为上面的代码是错误的,但它缺少能够运行我的 .exe 的东西。
新代码:
try
{
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec("C:\\PathToExe\\MyExe.exe");
InputStream stderr = proc.getErrorStream();
InputStreamReader isr = new InputStreamReader(stderr);
BufferedReader br = new BufferedReader(isr);
String line = null;
System.out.println("<ERROR>");
while ( (line = br.readLine()) != null)
System.out.println(line);
System.out.println("</ERROR>");
int exitVal = proc.waitFor();
System.out.println("Process exitValue: " + exitVal);
} catch (Exception e)
{
e.printStackTrace();
}
新输出:
