Hi VivekSharma609055,
I get those error if I am missing the Quotation mark or apostrophe. I have it like the example at: LOGIN Update Command Line Utility
Sample:
java -jar LOGIN_Update.jar -name "LOGIN.TEST*" -u_updloginsrc "['WIN99','WINDOWS','admin']" -u_updlogintrg "['WIN99','WINDOWS','newadmin','password']" -commit
