The method that adds objects to the cache requires the keys to be serializable, so a typical usage would be: def key = 22 def someObject = new Object(); cacheService.cache(key, true, someObject) (The boolean param indicates whether the object should be added to a distributed or local cac...

I am new to Java. Its only been six months but I do understand Java. While reading about it sometimes, I come across these terms - Groovy, Grails, Hibernate, JBoss, Jade and many more.

I have a controller that needs to return a 404 page and status code on certain conditions. I can't seem to find out how to do this in Grails. A coworker recommended this method: response.sendError(HttpServletResponse.SC_NOT_FOUND) which works perfectly fine, but it's not very Grails-like. I know Rails' render method take a status argu...
