in config.groovy

grails.web.url.converter = 'hyphenated' 

// grails-app/conf/spring/resources.groovy

beans = {     "${grails.web.urlconverter.bean_name}"(com.myapplication.myurlconverterimpl) } 

in when trying character in small letter below url

e.g :abc.com/newuser/viewuser/4

its working fine

but when add underscore in between 2 character below url

e.g :abc.com/new_user/view_user/4

its gives error 404.. please me out. if have other option change url welcome..

thank

one of easiest way achieve requirement urlmappings.groovy

"/new_user/view_user/$id"(controller: 'newuser', action: 'viewuser')
