Dear Wiki user, You have subscribed to a wiki page or wiki category on "Jakarta-velocity Wiki" for change notification.
The following page has been changed by WillGlassHusain: http://wiki.apache.org/jakarta-velocity/StdErrLogSystem The comment on the change is: move from contrib to Wiki New page: Contributed by Christoph Reck <[EMAIL PROTECTED]> with the following [edited] message to the user list: For anyone interested, I've created a simple !StderrLogSystem as a drop-in for Velocity - see attachment. Either it can be taken into the velocity contribution section, or put into velocity as the standard logger, or you can change the package name to whatever you want and include it in your distribution. The reason for this is that I do not want stray files created (velocity.log) in my file system when running my Anakia commandline tool. I use it as follows: '''within main()''' {{{ // The classname of the default logger to be used String loggerClass = "StderrLogSystem"; Vector vargs = new Vector(); for( int i = 0; i < args.length; ++i ) { if( args[i].equals("-quiet") ) loggerClass = "org.apache.velocity.runtime.log.NullLogSystem"; else if( args[i].equals("-verbose") ) loggerClass = "StderrLogSystem"; else vargs.add( args[i] ); } }}} '''and for the ve.init():''' {{{ templatePath = new File(templatePath).getCanonicalPath(); velocity = new VelocityEngine(); velocity.setProperty(RuntimeConstants.FILE_RESOURCE_LOADER_PATH, templatePath); velocity.setProperty(RuntimeConstants.RUNTIME_LOG_LOGSYSTEM_CLASS, loggerClass); velocity.init(); }}} '''NOTE: templatePath is "." for my current XmlTransformer batch tool.'''
