java - Unable to use Scala and Spring MVC 3 to return JSON -

-

i converting java spring controller classes scala. in java, controller method returned json defined this:

@requestmapping(value = "/search", method = requestmethod.get) public @responsebody string[] searchfoods(@requestparam("term") string searchterm, principal principal) { ... }

this works expected. same method in scala looks this:

@requestmapping(value = array("/search"), method = array(requestmethod.get)) def searchfoods(@requestparam("term") searchterm: string, principal: principal): java.util.list[string] @responsebody = { ... }

however, time path requested following exception:

2011-10-09 09:06:19.980:warn::/searchpath/search.html javax.servlet.servletexception: not resolve view name 'searchpath/search' in servlet name 'dispatcher' @ org.springframework.web.servlet.dispatcherservlet.render(dispatcherservlet.java:1029)

and web server returns http 500 error. possible use scala , spring mvc 3 return json?

looks putting @responsebody in wrong place. needs appear before method definition:

@requestmapping(value = array("/search"), method = array(requestmethod.get)) @responsebody def searchfoods(@requestparam("term") searchterm: string, principal: principal): java.util.list[string]  = { ... }

i had tried before, forgot clean project. after moving annotation correct location, cleaning , rebuilding, working again. thanks!

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
