title: Clientsided data-cleaning and analysis with sturts2
body: <p>right now I'm trying to implement a webapp that does data cleaning and analysis and I have already a prototype written in Java. For the analysis part I tend to use WEKA (http://www.cs.waikato.ac.nz/ml/weka/). Because of performance reasons I thought it might be a good idea to let the client do most of the work. I started to learn struts2 and I have no experience using JavaScript. My questions are:</p>
  
  <ol>
  <li><p>Is struts2 the right choise for this task?</p></li>
  <li><p>Should I write a Java Applet or can it also be done by Java Script?</p></li>
  </ol>
  
  <p>I don't have enough experience nor have I found a good solution searching the internet. Can you perhaps post some tutorials or websites that might help me with my questions?</p>
