Command Button links to incorrect Path Name in a Spring Web Flow Project

Question

I am trying to add two numbers together and display the output, but I'm having rendering problems.

I get this from the ajax log. (Spaced out for readability)

info [12:44:10.893]: Element error 
<error>
  <error-name>
    class com.sun.faces.context.FacesFileNotFoundException
  </error-name>
  <error-message>
    <![CDATA[/WEB-INF/WEB-INF/intro.xhtml Not Found in ExternalContext as a Resource]]>
  </error-message>
</error>

I do not see where it is getting the two WEB-INF folders in the path name.

The second part of the this question is that I am not sure where calculator.sum should be called at either. This may be effecting the result or need to be in a separate question. #{calculator.sum} is the output that is called when the button is clicked.

This is the form that I am editing.

 <rich:panel id="UserManagePanel" header="Welcome to test">

 <a href="main">Enter The WebFlow</a>
  <br/>
  <br/>
  <br/>
    <h:inputText id="additive1" value="#{calculator.a}"/>
  <br/>
    <h:inputText id="additive2" value="#{calculator.b}"/>
  <br/>
    <a4j:commandButton type="button" id="btn_add" action="#{calculator.sum}" value="Add" reRender="out" execute="@form"/>
  <br/>

  <a4j:outputPanel id="out">
    <h:outputText value="#{calculator.sum}" rendered="true"/>
  </a4j:outputPanel>
  <br/>

  <a4j:log/>

   </rich:panel>
  </h:form>

Answer 1

To get this to work a few things had to happen.

1) WEB-INF/ from the webmvc-config.xml under the flowlistener.
2) and had to be used to at least debug it.
3) The form must be in and tags.
4) The url must use webflow

http://localhost:8080/CLPWeb/spring/grantSearchFlow?test

  rather than

http://localhost:8080/CLPWeb/spring/WEB-INF/templates/views/test.xhtml

Used url's as code to get it to validate.

Answer 2

Since the calculator.sum only returns the number (and doesn't do anything in the background) there is no point calling it when you click the button.

I don't know what causes the error but WEB-INF is for config files and stuff like that. If you have any (x)html pages in there move them out.
