title: Scala Getting class type from string representation
body: <p>I have a class name string representation </p>
  
  <pre><code>val cls = Class.forName("clsName")
  def fromJson[T: Manifest](me: String): T = {
  Extraction.extract[T](net.liftweb.json.parse(me))
  }
  </code></pre>
  
  <p>I would like to use it as T:manifest i.e </p>
  
  <pre><code>JsonConverter.fromJson[cls.type](stringData)
  </code></pre>
  
  <p>this returns an error</p>
  
  <p>tried also  </p>
  
  <pre><code>val t = Manifest.classType(cls)
  JsonConverter.fromJson[t](stringData) // compile error 
  </code></pre>
  
  <p>what is the best way to it ? is there a way to avoid using reflection ? </p>
