在Java程序中运行批处理文件

Question

There is batch file that contains a jar file. I want to run a batch file in a java program in netbeans. I used this code:

Process p=    Runtime.getRuntime().exec("cmd /c  start  \"C:\\Users\\123\\Desktop\\New folder (6)\\Browser.bat\"");

But by running this code, a cmd windows in open and below address is shown and batch file doesn't run.

C:\Users\123\Documents\NetBeansProjects\JavaApplication19

That is different from the address of batch file.

batch file contains:

java -jar -Xms32m -Xmx512m Browser.jar

using ProcessBuilder: the jar file runs.

ProcessBuilder pb = new ProcessBuilder("java.exe", "-jar","-Xms32m", "-Xmx512m", "C:\\Users\\123\\Desktop\\New folder (6)\\Browser.jar");
  pb.directory(new File("C:\\Windows\\System32"));
  Process p = pb.start();

using ProcessBuilder for batch file: program runs successfully but jar file not execute.

ProcessBuilder pb = new ProcessBuilder("java.exe", "-jar","-Xms32m", "-Xmx512m", "C:\\Users\\Saeedeh\\Desktop\\New folder (6)\\FarsNetBrowser.jar");
pb.directory(new File("C:\\Windows\\System32"));
Process p = pb.start();

Answer 1

I think there's an extra start in your command line. It should work by just using

cmd /c "C:\Users\123\Desktop\New folder (6)\Browser.bat"

and I would let Java escape argument instead of hardcoding the string:

new ProcessBuilder("cmd", "/c", PATH_OF_THE_BAT_FILE);

Answer 2

Process p = Runtime.getRuntime().exec("cmd /c start \"C:/Users/123/Desktop/New folder (6)/Browser.bat\"");
