title: Spring WebFlow: How to get request parameters in JSP?
body: <p>I'm using Spring WebFlow together with Spring MVC. When i request page for example <code>http://localhost:8080/testapp/index.html?param=100</code> WebFlow make redirect to <code>http://localhost:8080/testapp/index.html?execution=e3s1</code> and can't get <code>param</code> in jsp, <code>param</code> lost somewhere. How to get this working ?</p>
  
  <p>Another example of this situation - Spring Security configured like below:</p>
  
  <pre><code>&lt;security:form-login authentication-failure-url="/login.html?loginfail=1" login-page="/login.html" /&gt;
  </code></pre>
  
  <p>When login fail, i can't get <code>loginfail</code> parameter in <code>login.jsp</code>.</p>
  
  <pre><code>&lt;c:if test="${!empty param.loginfail}"&gt;Login error!&lt;/c:if&gt;
  </code></pre>
  
  <p>I can access request parameters in flow, but... Do i have to set view/flowScope variables for all my request parameters like below ?</p>
  
  <pre><code>&lt;set name="viewScope.loginfail" value="requestParameters.loginfail" /&gt;
  </code></pre>
