title: Can't find Vaadin ClassResource
body: <p>I'm trying to use the Vaadin ClassResource class to load my database connection properties from a file that will be deployed with the WAR, but I can't seem to find the file.  I am using Vaadin 6.5.2, Tomcat 7.0.6, and I've placed my "app.properties" file in the same package as my Application main file.</p>
  
  <p>My code is in Scala. Here's what I try:</p>
  
  <pre><code>val cr = new ClassResource("app.properties",this) // "this" is the application
  debug("resource mimeType = {}",cr.getMIMEType)
  debug("resource bufferSize = {}", cr.getBufferSize)
  debug("resource cacheTime = {}",cr.getCacheTime)
  debug("resource fileName = {}", cr.getFilename)
  val ds = cr.getStream
  if (ds != null) {  
    debug("download stream bufferSize = {}", ds.getBufferSize)
    debug("download stream cacheTime = {}",ds.getCacheTime)
  
    val is = ds.getStream // get InputStream
  
    if (is != null) {
      val props = new Properties
      props.load(is)
      val dbHost = props.get("db.host").asInstanceOf[String]
      val dbName = props.get("db.name").asInstanceOf[String]
      val dbPort = props.get("db.port").asInstanceOf[String]
      val dbUser = props.get("db.user").asInstanceOf[String]
      val dbPass = props.get("db.pass").asInstanceOf[String]
      val dbUri = props.get("db.uri").asInstanceOf[String]
    } else {
      debug("Input stream was null")
    }
  } else {
    debug("Download stream was null")
  }
  </code></pre>
  
  <p>And here is the result:</p>
  
  <pre><code>08:51:59.617 ["http-bio-8084"-exec-11] DEBUG c.sentientswarm.propdesk.AppConfig$ - resource mimeType = application/octet-stream

  08:51:59.621 ["http-bio-8084"-exec-11] DEBUG c.sentientswarm.propdesk.AppConfig$ - Input stream was null
  </code></pre>
  
  <p>I've tried placing the config file in various locations including the top of src, inside the top of the VAADIN folder that holds themes, and where it currently is (in the same package as the main Application), but the results are always the same.  Can anyone tell me what I'm doing wrong???</p>
