How to create a new User remotely using Poweshell from inside a java program?I am getting following error

I want to run a PowerShell command for create user using Java on a remote windows machine, I am writing this code in eclipse.
And below is the output, tried every reference and forms to resolve this issue can someone help me with this.
The command works on PowerShell command line, but it is not working in Java.
public class PowerShellSession {
private static String subModule = "PowerShellSession";
String targetIpAddress;
String username;
String password;
public static Object connectPShellLock = new Object();

//String ex = "New-LocalUser -Name \"User02\" -Description \"Description of this account.\" -NoPassword";
String ex = credentials +" Invoke-Command -ScriptBlock {" + cmd + "} -ComputerName " + targetIpAddress +" -Credential $mycred";
String[] args = new String[] { "powershell", ex};
try {
execRemote(args);
} catch (IOException e) {
e.printStackTrace();
}
}
public void close() {
String command = "Exit-PSSession";
String[] args = new String[] { "powershell", command};
try {
execRemote(args);
} catch (IOException e) {
e.printStackTrace();
}
}

//creds += "$session = New-PSSession -ComputerName " + domain + " -Credential $mycred;";
String[] args = new String[] { "powershell", creds};
execRemote(args);
return creds;
}
private void execRemote(String[] arguments) throws IOException {
ProcessBuilder builder = new ProcessBuilder(arguments);
builder.redirectErrorStream(true);
Process process = builder.start();
doProcessIO(process);
}
// Do the IO for a passed process
private void doProcessIO(Process p) throws IOException {
p.getOutputStream().close();
String line;
System.out.println("Output:");
BufferedReader stdout = new BufferedReader(new InputStreamReader(
p.getInputStream()));
while ((line = stdout.readLine()) != null) {
System.out.println(line);
}
stdout.close();
System.out.println("Error:");
BufferedReader stderr = new BufferedReader(new InputStreamReader(
p.getErrorStream()));
while ((line = stderr.readLine()) != null) {
System.out.println(line);
}
stderr.close();
System.out.println("Done");
}
public static void main(String[] args) throws IOException {
String ip_add = "192.168.193.101";
String user = "gs-259412";

PowerShellSession psSession = new PowerShellSession();
String credentials = psSession.getCredentials(ip_add, user, pass);
psSession.targetIpAddress = ip_add;//;

if(!credentials.equals("")) {
psSession.exec(cmdd, credentials);
System.out.println("Finished PowerShell remote session.");
}
psSession.close();
}
}
Output of this program :

runtime.exec(batchCommand) - Issues with Space in folder

Below method return me below path
Output - "C:\ProgramData\MySQL\MySQL Server 5.5\bin\"
private String getPath() {
String mysqlpath = "";
try {
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection(dbUrl, user, password);
Statement stmt = con.createStatement();
ResultSet res = stmt.executeQuery("select ##datadir");
while (res.next()) {
mysqlpath = res.getString(1);
}
mysqlpath = mysqlpath.replace("\\Data", "\\bin").replace("\\", "\\\\");
System.out.println("Mysql path is :" + mysqlpath);
} catch (Exception ee) {
System.out.println(ee);
}
return mysqlpath;
}
Now i run below command to export mysql dump.
Runtime runtime = Runtime.getRuntime();
Process p = runtime.exec(batchCommand);
batchCommand - "C:\ProgramData\MySQL\MySQL Server 5.5\bin\mysqldump" -h localhost --port 3306 -u root --password=root123 --add-drop-database -B accountingbook -r "E:\softwares\Tomcat_accountingBook\webapps\accountingbookaccountingbook-localhost-(02-08-2017).sql"
Exception - java.io.IOException: Cannot run program ""C:\ProgramData\MySQL\MySQL": CreateProcess error=2, The system cannot find the file specified
I also tried below, but same issue:-
1.) Process p = runtime.exec(batchCommand.split(" "));
2.) Adding double quotes like "C:\ProgramData\MySQL\MySQL Server 5.5\bin\"
Problem is it breaks as soon as it encounters space.

From the Exception, it looks like JVM is not able to find MYSQL executable file at the location given.
This can be due to "\" file separator. Try using "\\" to separate your paths. Then your path would be : "C:\\ProgramData\\MySQL\\MySQL.

use java to dump mysql database

I am using Ubuntu. I want to use java application to dump the MySQL database. Below are my code:
String userName = "root";
String userPassword = "root";
String oldDatabaseName = "testing";
String executeCommand = "";
executeCommand = "mysqldump -u "+userName+" -p"+userPassword+" --no-data "
+OldDatabaseName+" > testingbackup.sql";
Process runtimeProcess = Runtime.getRuntime().exec(executeCmd);
int processComplete = runtimeProcess.waitFor();
if(processComplete == 0){
System.out.println("Backup successful.");
}else{
System.out.println("Backup failed.");
}
But, when I run the above program, I always get the "Backup failed" message.
Am I writing the wrong code? And what library/file I need to include in my java application? Any help please.

This is working fine in my windows machine.
package org.some.test;
import java.io.File;
public class dateformat {
private static final String dbUserName = "root";
private static final String dbPassword = "manager";
private static final String dbName = "opencms";
public static void main(String[] args){
try {
File path =new File("D:\\dump1.sql");
String[] executeCmd = new String[]{"C:/Program Files/MySQL/MySQL Server 5.6/bin/mysql", "--user=" + dbUserName, "--password=" + dbPassword,""+ dbName,"-e", "source "+path};
Process p = Runtime.getRuntime().exec(executeCmd);
int processComplete = p.waitFor();
if (processComplete == 0)
{
System.out.println("Restore created successfully");
//return true;
}
else
{
System.out.println("Could not restore");
}
} catch (Exception e) {
e.printStackTrace();
}
}
}

It seems to me you omitted a space between -p and quote:
-p "+userPassword+
^-- insert space here

There's a tutorial that shows you without using Runtime.exec() function and uses specifically java.util.prefs.WindowsPreferences.

How to insert and retrieve key from registry editor

I am new to cryptography. I have to develop project based on cryptography..In part of my project I have to insert a key to the registry and afterwards I have to retrieve the same key for decryption.. I done until getting the path of the registry ..
Here I am showing my code:
import java.io.IOException;
import java.io.InputStream;
import java.io.StringWriter;
public final class Project {
public static final String readRegistry(String location, String key) {
try {
// Run reg query, then read output with StreamReader (internal class)
Process process = Runtime.getRuntime().exec("reg query " +
'"' + location + "\" /v " + key);
StreamReader reader = new StreamReader(process.getInputStream());
reader.start();
process.waitFor();
reader.join();
String output = reader.getResult();
// Output has the following format:
// \n<Version information>\n\n<key>\t<registry type>\t<value>
if (!output.contains("\t")) {
return null;
}
// Parse out the value
String[] parsed = output.split("\t");
return parsed[parsed.length - 1];
} catch (Exception e) {
return null;
}
}
static class StreamReader extends Thread {
private InputStream is;
private StringWriter sw = new StringWriter();
public StreamReader(InputStream is) {
this.is = is;
}
public void run() {
try {
int c;
while ((c = is.read()) != -1) {
System.out.println("Reading" + c);
sw.write(c);
}
} catch (IOException e) {
System.out.println("Exception in run() " + e);
}
}
public String getResult() {
System.out.println("Content " + sw.toString());
return sw.toString();
}
}
public static boolean addValue(String key, String valName, String val) {
try {
// Run reg query, then read output with StreamReader (internal class)
Process process = Runtime.getRuntime().exec("reg add \"" + key + "\" /v \"" + valName + "\" /d \"\\\"" + val + "\\\"\" /f");
StreamReader reader = new StreamReader(process.getInputStream());
reader.start();
process.waitFor();
reader.join();
String output = reader.getResult();
System.out.println("Processing........ggggggggggggggggggggg." + output);
// Output has the following format:
// \n<Version information>\n\n<key>\t<registry type>\t<value>
return output.contains("The operation completed successfully");
} catch (Exception e) {
System.out.println("Exception in addValue() " + e);
}
return false;
}
public static void main(String[] args) {
// Sample usage
JAXRDeleteConcept hc = new JAXRDeleteConcept();
System.out.println("Before Insertion");
if (JAXRDeleteConcept.addValue("HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\ComDlg32\\OpenSaveMRU", "REG_SZ", "Muthus")) {
System.out.println("Inserted Successfully");
}
String value = JAXRDeleteConcept.readRegistry("HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\ComDlg32\\OpenSaveMRU" , "Project_Key");
System.out.println(value);
}
}
But i dont know how to insert a key in a registry and read the particular key which i inserted..Please help me..
Thanks in advance..

It would be a lot easier to use the JRegistry library to edit the registry, rather than execute commands.
