How can I set bean property in JSF page?!

[Pavels Hlopoks]

Hello!

I have

    
 
public class HeaderBacking {
    private String secondLevel = null;
 
           public HeaderBacking(){
        
        secondLevel = new String("--- first---");
     
    }
 
        public void setSecondLevel(String secondLevel) {
        this.secondLevel = secondLevel;
    }
 
    public String getSecondLevel() {
        return secondLevel;
    }
}
 

have jsp page

   
 
   <h:outputText value="#{headerBacking.secondLevel}"/>
    
    <c:set target="headerBacking" scope="request"  property="secondLevel" value="-----yeeee-----"/>
    <h:outputText value="#{headerBacking.secondLevel}"/> 

and have faces.xml

    
<managed-bean>
    <managed-bean-name>headerBacking</managed-bean-name>
    <managed-bean-class>lt.it.webforce.framework.backing.header.HeaderBacking</managed-bean-class>
    <managed-bean-scope>request</managed-bean-scope>
</managed-bean>

when I run it, get in output

"
--- first---
--- first---
"
I other words JSTL <c:set /> is not working... Why?

Please help me...

I do not know if the JSTL "set" will work with JSF. However, can't you just use another variable for the second level output? If you are looking to have both of the values appear on the same page then you would be making a cleaner solution by using two separate variables in my opinion.

Josh, thanks for your response ;)

But I really need to set managed bean property from jsf page. In our architecture it is required for menu...

Sombody can answer me - how can set managed bean property from JSF page?

Dear Pavels,

If you don't force to use JSTL , you can set the bean properties by JSF easy.
Look:

UserBean bean = new UserBean(); // your bean class

ExternalContext context =
FacesContext.getCurrentInstance().getExternalContext();
HttpServletRequest request =
(HttpServletRequest)context.getRequest();

String fullName = request.getParameter("form1:fullName");
bean.setFullName(fullName);

you can do this in utility class.

I hope it can help you.

    UserBean bean = new UserBean(); // your bean class
 
ExternalContext context =
FacesContext.getCurrentInstance().getExternalContext();
HttpServletRequest request =
(HttpServletRequest)context.getRequest();
 
String fullName = request.getParameter("form1:fullName");
bean.setFullName(fullName); 

Hmmm ... For example managed bean in faces config looks like :

    
<managed-bean>
    <managed-bean-name>userBean</managed-bean-name>
    <managed-bean-class>bean.UserBean</managed-bean-class>
    <managed-bean-scope>request</managed-bean-scope>
</managed-bean>

How I can get it from request?

Why you wrote: String fullName = request.getParameter("form1:fullName");

Why "form1:fullName"??

[zohreh talebi]

Ok ,

How I can get it from request?
By this:

ExternalContext context =
FacesContext.getCurrentInstance().getExternalContext();
HttpServletRequest request =
(HttpServletRequest)context.getRequest();

Why you wrote: String fullName = request.getParameter("form1:fullName");

beacuase of this is for example your JSP :

<h:form id="form1" >
First Name :
<h:inputText id ="fullName" value="#{dbBean.fullName}"/>

        HttpServletRequest request1 = (HttpServletRequest) fc.getRequest();
        
        lt.it.webforce.framework.backing.header.HeaderBacking 
        hb  = (lt.it.webforce.framework.backing.header.HeaderBacking) request1.getAttribute("headerBacking");
        
        
        java.util.Enumeration en = request1.getAttributeNames(); 
        //java.util.Enumeration en = request1.getAttributeNames();
        
        for ( ; en.hasMoreElements() ;) {
         System.out.println(en.nextElement());
 
        }
        
        System.out.println("---------------- bean from Request = " + hb);
        
        if (hb==null){
            hb = new lt.it.webforce.framework.backing.header.HeaderBacking();
        }
        
        hb.setSecondLevel("second");
        
        System.out.println("from JSF = " + hb.getSecondLevel()); 
    </jsp:scriptlet>
    
    <h:outputText value="#{headerBacking.secondLevel}"/>
    
    <c:set target="${sessionScope.headerBacking}" property="secondLevel" value="second"/>
    
 </f:subview>
 
</jsp:root>

how can see i try get bean from request...

    <managed-bean>
    <managed-bean-name>headerBacking</managed-bean-name>
    <managed-bean-class>lt.it.webforce.framework.backing.header.HeaderBacking</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
    
  
</managed-bean>

And I have some bean - how Can I get HeaderBacking from request?

when I try get all RequestParemeterNames - I can't see my "headerBacking", like in faces config...

jspx is jsp page in xml syntax.
