I downloaded the Apache James mailing server Apache-james-3.0-beta4-app . I tried to run it on Windows 7 ultimate by clicking on run.bat file inside following directory
C:\Users\Jack\Desktop\New folder\Servers\MailServer\apache-james-3.0-beta4-app\apache-james-3.0-beta4\bin.
Command prompt started for a while and it is getting disappeared. I am not able to read the error on the command prompt as it is so quick. Any kind of suggestion would be appreciated. When I am running telnet command in command prompt it is showing that command not recognized. I don't know how to turn it on in Windows.
