The console below is always null, where would be the problem? Only when I am in eclipse, I can run the application properly with java MainDocument

import java.io.Console;
import java.sql.SQLException;


public class MainDocument {
  public static void main(String[] args) throws ClassNotFoundException, SQLException {
    Console console = System.console();
    if (console == null) {
      System.err.println("sales: unable to obtain console");
      return;
    }

    console.printf("%s ", "string");
  }
}

result=> sales: unable to obtain console


I have set the path X:\Sun\sdk\jdk\bin to no avail.
I guess there is something wrong with classpath or whatsoever... but not sure how to setup.... could anyone help me out?
Any suggestions?

I'm not sure if that's an Eclipse problem. From reading Console (Java Platform SE 6) it seems it will return null if no console device is available.

Thanks for your reply. What strange to me is that I can't run/debug all applications as "Debug as Application" that used to run fine before I re-install xp, some can be run using "debug as applet"..... The console thing is okay when I run on the command prompt..... but maybe you're right
Thanks

I wonder if you've got the same JRE/JDK setup in Eclipse that you are using on the command line?

I have been trying the settings all night. But this is very discouraging, I couldn't achieve anything... What settings can I look into?
Thanks in advance

Check Window/Preferences/Java/Installed JREs and check that the JRE that you are using is the same as that on the command line.

I'm going to try this out from my own machine now and will let you know

Hey Jack

Well it looks like it can't work in Eclipse - I tried it, got the same as you, and read about it:

EclipseZone - System.console() doesn't in Eclipse ...

So, you won't be able to use the Console inside Eclipse, but when you deploy this program outside of Eclipse, it should work fine.

Maybe you can work around this and use some approach other than Console?

At least this puts an end to your searching :-)

It is called jre1.60_06....
The zip file I have is java_ee_sdk-5_04-windows
And also how can I tell which version I am using on the command prompt?
Thanks
