Hi All,
I am facing issue in System.console() when i call the executable jar file inside windows batch script. Now what is my use case i am writing windows batch script for my business case and i need to get password of database from the user.
So to mask the password entered by user i try to create a
Java executable and tried calling inside the windows batch file. The problem is if i run my executable directly in command prompt this works fine and the password is masked.
But if i call the same jar inside batch script its not able to get the System.console() i understand if its running inside batch script this should also be in console mode or is it different .
Below is my sample code of java class and the batch script . Can some one help me on this .
Java code :
import java.io.Console;
public class MyPasstesting {
public void passwordExample() {
Console console = System.console();
if (console == null) {
System.out.println("Console is empth ");
System.exit(0);
}
char passwordArray[] = console.readPassword("Enter your secret password: ");
console.printf(new
String(passwordArray));
}
public static void main(String[] args) {
new MyPasstesting().passwordExample();
}
}
Exported the project in to Runnable jar 'test.jar'
Batch script :
@ECHO OFF
@CALL :getPassword pwd
@echo "What i got SCN :" %pwd%
:getPassword
@echo off
setlocal enableDelayedExpansion
for /f "delims=" %%J in ('java -jar test.jar') do (
set "spwd=!spwd! %%J"
)
endlocal & set spwd=%spwd%
@SET %1=%spwd%
@GOTO :eof
