java - What package do I import to use the Play Framework javaextensions? specifically 'since()' -

edit:

this code:

public string tminus(long id) {    plan myentity = entity.find.byid(id);    string timeago = myentity.checkintime.since();     return "timeago"; } 

i'm getting error when try use since() method:

cannot find symbol [symbol: method since()] [location: class java.util.date] 

are talking playframework 1.x? if case can use java extensions in groovy template:

${mydate.since(...)} 

you can use java extensions in rythm template if use rythm plugin:

@mydate.since(...) 

if want use java extensions in java program, have way:

templates.javaextensions.since(mydata, ...)
