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

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">
Enter The WebFlow
<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>

Java class Calculator.java
package demo;
import javax.faces.bean.*;
import org.springframework.stereotype.Component;
#ManagedBean
#Component
#ViewScoped
public class Calculator implements java.io.Serializable{
private static final long serialVersionUID = -3832235132261771583L;
private int _a;
private int _b;
public int getA() { return _a; }
public void setA(int a) { _a = a; }
public int getB() { return _b; }
public void setB(int b) { _b = b; }
public int getSum()

return _a + _b;
}
}
Libraries I'm Using:
Using Richfaces 4.3.4
Spring Security 3.1.3
JSTL 1.2.1
Spring 3.2.0.RELEASE

Answer 1

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.

Answer 2

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.
