serving a static html page

[Tommy Chheng]

I have a static html page in webapp/WEB-INF/views/dashboard.html

How can I render this in a get handler?

I tried both these but get null pointer exceptions. How should i be referencing the path correctly?

  get("/dashboard"){

    contentType = "text/html"

    val path = "/views/dashboard.html"

    new java.io.File( getServletContext().getResource(path).getFile )

  }

  get("/dashboard"){

    contentType = "text/html"

    val path = "/views/dashboard.html"

    val input = getServletContext().getResourceAsStream(path)

    org.apache.commons.io.IOUtils.readLines(input).mkString("")

  }

If it's returning nulls, sounds to me like it's not finding that
file. I forget what the root of of ServletContext.getResource() is -
I'm using to having things in WEB-INF/classes to read them off the
classpath.
I believe you might need to put the "/WEB-INF" as part of your path,
like "/WEB-INF/views/dashboard.html".
However, if you're just serving a static file, why have it in WEB-
INF? That directory's more for code things. ScalatraServlet has a
handler that will serve a static file in the top-level of your webapp
if no route is defined for it:
https://github.com/scalatra/scalatra/blob/develop/core/src/main/scala/org/scalatra/ScalatraServlet.scala#L65
That's the default behaviour for Filters, as well.

If you really do need to muck with the request / response
programaticlly, yes, you can return a File reference, and Scalatra
will serve it, with the code here:
https://github.com/scalatra/scalatra/blob/develop/core/src/main/scala/org/scalatra/ScalatraServlet.scala#L65

The ServletContext is available for you as a variable called
"servletContext":
http://www.scalatra.org/2.1/book/#ServletContext
So returning new File(servletContext.getResource("/WEB-INF/views/
dashboard.html")) should work.
You can also add to that renderPipeline, perhaps something that will
turn URLs into Files for you, and do the same thing.

You can move the file out of the WEB-INF directory

so instead of webapp/WEB-INF/views/dashboard.html it should be
webapp/views/dashboard.html


and things should be served automatically

Thanks for the informative post! I ended up using the past tip.
