title: Converting RxJava to RxScala
body: <p>Is there a way to use both <em>RxJava</em> and <em>RxScala</em> in one project? </p>
  
  <pre><code>import rx.lang.scala.{Observable =&gt; ScalaObservable}
  import rx.{Observable =&gt; JavaObservable}
  </code></pre>
  
  <p>We have a module written in Java that is using the <code>JavaObservable</code> (<em>RxJava</em>). And then we have a Scala module that is supposed to use the Java module but is written in Scala.</p>
  
  <p>Are there convenient methods to transform these into the other?</p>
