Twitter demo throwing exception when visited in web browser

[sanity]

I follow the instructions in the readme, but when I visit http://localhost:8080/ I get the following error:

HTTP ERROR 500

Problem accessing /. Reason:

    javax.servlet.http.HttpServletResponse.getStatus()I

Yeah I noticed this as well. Scalatra seems to have changed somewhat more significantly than the other dependencies. I'll try and get this working real quick.

[seregasheypak]

I get the same when trying to run simple scalatra project. Are there any ideas what's wrong?

[earldouglas]

I can't get it to complete a connection at all to localhost:8080. The error looks like Scalatra is expecting a different version of the servlet api.

What if you change the following in Build.scala:

val servletApi = "javax.servlet" % "servlet-api" % "2.5"

to:

val servletApi = "javax.servlet" % "javax.servlet-api" % "3.0.1"

I've used maven instead of sbt. I'm new to Scala, so I decided to acquire new knowledge in several steps. It was typical jar hell and open-source "naming conventions" :) If someone needs, I can share pom.xml with latetest version which are compatible.
