title: request.getparameter not working on multiple servlets
body: <p>When the user fills the Sign up form(on page <code>Reg.jsp</code>) the data is successfully forwarded to the servlet(<code>Regi.java</code>) and when i use <code>&lt;%=request.getParameter("username")%&gt;</code> on one of my jsp pages(<code>Imgu.jsp</code>-which asks user to upload image) it works fine but when the same data is requested on another servlet(<code>imgup.java</code>) the value of parameter username is null.</p>
  
  <p>I cannot understand why this happens i have tried creating a session but it did not work.</p>
