Run cmd commands through java processBuilder

Question

I am trying to use ProcessBuild to run the cmd statement.

ProcessBuilder pb = new ProcessBuilder("cmd.exe", "/C", "start");
Process p = pb.start();

However, I can only open the cmd.exe

I do not know how to add statement to the ProcessBuild so that the all the jar in the folder can run. Usually, I open the cmd in the stanford-corenlp-full-2015年12月09日 folder, and add this statement to run: java -mx4g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer
enter image description here

So how to write this statement Run cmd commands through java?? I am getting errors as the statement consists "*". How to edit the ProcessBuilder so that i can run the statement? Thanks a lot

Answer 1

You could set the directory from where the command to be executed

 List<String> cmds = Arrays.asList("cmd.exe", "/C", "start", "java", "-mx4g", "-cp", "*", "edu.stanford.nlp.pipeline.StanfordCoreNLPServer");
 ProcessBuilder builder = new ProcessBuilder(cmds);
 builder.directory(new File("D:/stanford-corenlp-full-2015年12月09日"));
 Process proc = builder.start();

UPDATE as requested in comments

 OutputStream out = proc.getOutputStream();
 new Thread(() -> {
 try (BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(out))) {
 bw.write("[command here]");
 bw.flush();
 } catch (IOException ioe) {
 ioe.printStackTrace();
 }
 }).start();
