title: A problem with jsp requested parameters in tomcat
body: <p>I've created a JSP project with netbeans 7.0 and tomcat 7.0 too with no problem.</p>
  
  <p>When I export it to a WAR and deploy it into my Tomcat server this line doesn't work:</p>
  
  <pre><code>&lt;% if (request.getParameter("submit").contains("اضافه")) { ...
  </code></pre>
  
  <p>but these ones works:</p>
  
  <pre><code>&lt;% if (request.getParameter("emplist") != null) { ...
  </code></pre>
  
  <p>How is this problem caused and how can I solve it?</p>
