title: Rserve connection fails
body: <p>I am using <a href="https://wiki.52north.org/Geostatistics/WPS4R" rel="nofollow noreferrer">WPS4R provided by 52north</a></p>
  
  <p>Up to 3 days ago everything was fine and WPS could connect to R by use of Rserve properly but now this connection can not be made. I uninstalled everything, including Apache Tomcat,R and Java JDK, and then installed everything again. the problem still exists. This is the error that I get when I send the request. I am sure the code I used is correct, because it used to work and I did not chang any thing .</p>
  
  <p>This is the error:</p>
  
  <pre><code> An R Connection Error occoured:
      class org.rosuda.REngine.Rserve.RserveException - eval failed,
      request status: error code: 127 null
  </code></pre>
