Java无法使用ProcessBuilder运行Exec Jar

Question

I am running these line of codes to run a Test.jar which is an executable jar

public static void main(String[] args) throws IOException{

        File f = new File("path to exe jar");
        if(f.exists() && !f.isDirectory()) { 
           System.out.println("Valid");
        }else{
            System.out.println("Invalid");
        }


        ProcessBuilder pb = 
                new ProcessBuilder("path to exec jar", "-jar", "Test.jar",
                        "args1","args2","args3","args4");
        pb.directory(new File("path to exec jar"));
        Process p = pb.start();

    }

And I keep getting this error: File is valid though so I think this might be access issues. What do I need to add to get the access needed?

Valid
Exception in thread "main" java.io.IOException: Cannot run program "abc" (in directory "abc"): CreateProcess error=5, Access is denied

Answer 1

"path to exe jar" should be "java" in the constructor for ProcessBuilder . You can't execute a path.
