Error starting Sun's native2ascii: In Grails

groovy with eclipse: first install testng plugin ; then groovy plugin; set grails_home path; run it as s java application. ------------------------------------- If you run app in Grails and get this error message and app cannot run.This happened sometimes because you want to use i18n feature in your application. Then try this method: Copying %Java_Home%/lib/tools.jar to %Java_Home%/jre/lib/ext/tools.jar fixed this problem. (a better approach is to set up JRE path to the directory JDK) http://grailslog.blogspot.com/2008/09/error-starting-suns-native2ascii-in.html
