Use the valditor's message in HelloWorld in SE Hello World Example ------------------------------------------------------------------ Key: WELDX-76 URL: https://jira.jboss.org/jira/browse/WELDX-76 Project: Weld Extensions Issue Type: Feature Request Components: Weld Extensions Environment: n/a Reporter: Wolfgang Frech It looks like an incomplete refactoring: The CommandLineArgsValidator creates an error message, but the HellWorld class does not read the message from the validator, but prints its own (identical) message. Use for (String message: argsValidator.getErrors()) System.out.println( message ); instead of System.out.println( "Please provide just one argument: your first name" ); in printHello by the way - cosmetic: use emptyList instead of deprecated EMPTY_LIST in CommandLineArgsValidator in SE Hello World Example -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
