Re: refering a web app file with FileRepresentation

Hello,

>what that result.tmpl file contains?
actually, result.tmpl intends to be a freemarker template.

Hi,

what that result.tmpl file contains? is there a way to load ftl files using CLAP, from web application context, like i am planning to store files either in WEB-INF or classes folder.

Thanks for your help.

    I don't think a java.io.File can be instantiated with a CLAP URI
    (CLAP is a pure Restlet concept). I just suggested you to create a
    FileRepresentation from either a CLAP or a WAR URI in order to
    return a Representation of a file.

    If you want to build your HTML representations with Freemarker,
    you can
    either:
     - create a TemplateRepresentation with it's template name, which
    requires you to set up the Freemarker configuration as you do but
    with a
    standard directory => File templateDir = new
    File("c:/temp/template");
     - or create a TemplateRepresentation from a Representation of the
    template. For example:
    result = new TemplateRepresentation(new
    FileRepresentation("war:///items/result.tmpl",MediaType.TEXT_HTML),
    configme(), getItem(), MediaType.TEXT_HTML );

    I hope this will help you.

    Best regards,
