Tomcat with scalatra Error - NoSuchMethodError HttpServletRequest.getContentLengthLong

Question

I am getting the following error when I try to run a program in Tomcat:

java.lang.NoSuchMethodError: javax.servlet.http.HttpServletRequest.getContentLengthLong()J
org.scalatra.servlet.HttpServletRequestReadOnly.<init>(HttpServletRequestReadOnly.scala:56)
org.scalatra.ScalatraContext$class.scalatraContext(ScalatraContext.scala:71)

I am using Scalatra and Tomcat 7, and I am trying to do an AsyncResult with (akka actor). I am using maven and my dependencies are the following

    </dependency>

The line code where I am getting the error is

new AsyncResult {
    val is =
      Future {

I tried including dependencies, excluding dependencies, adding dependencies... but I couldn't solve it. Anyone knows how to fix it?

Answer 1

Finally I solved the problem using Tomcat 8, because the javax-servlet including in tomcat 7 didn't work for me.
