Thanks Julian for your quick response.

I have got to admit I have the terrible mania to do the things on my own.
So I have resolved the issue.

But now it is time to complicate the app adding all the JSP files.

Best Regads,
Jose

I am trying the tutorial of DZone but I degrade to NB 6.7.1 with JSF 1.2 and EJB 3.0.
And the webapp works fine but I can not merge no customer because, in my opinion,
the jsf page CustomerDetails.xhtm is not well build.

That is my opinion because it does not merge the customer. I have tried this,

<h:form>
<h:panelGrid columns="2" bgcolor="#eff5fa">
<h:outputLabel value="Customer ID:"/>
<h:inputText id="customerId" value="#{customer.details.customerId}" disabled="true"/>
<h:outputLabel value="Customer Name:"/>
<h:inputText id="customerName" value="#{customer.details.name}"/>
<h:outputLabel value="Credit Limit:"/>
<h:inputText id="creditLimit" value="#{customer.details.creditLimit}"/>
<h:outputLabel value="Discount Code"/>
<h:selectOneMenu id="discountCode" value="#{customer.details.discount}">
<f:selectItems value="#{customer.discountCodes}"/>
</h:selectOneMenu>
<h:outputLabel value="Email:"/>
<h:inputText id="email" value="#{customer.details.email}"/>
<h:outputLabel value="Phone:"/>
<h:inputText id="phone" value="#{customer.details.phone}"/>
<h:outputLabel value="Fax:"/>
<h:inputText id="fax" value="#{customer.details.fax}"/>
<h:outputLabel value="Address (Line 1):"/>
<h:inputText id="address1" value="#{customer.details.addressline1}"/>
<h:outputLabel value="Address (Line 2):"/>
<h:inputText id="address2" value="#{customer.details.addressline2}"/>
<h:outputLabel value="State:"/>
<h:inputText id="state" value="#{customer.details.state}"/>
<h:outputLabel value="City:"/>
<h:inputText id="city" value="#{customer.details.city}"/>
<h:outputLabel value="Zip:"/>
<h:inputText id="zip" value="#{customer.details.zip.zipCode}"/>
</h:panelGrid>
<h:commandButton id="back" value="Back" action="#{customer.list}"/>
<h:commandButton id="update" value="Update" actionListener="#{customer.update}">
<f:attribute name="attName" value="#{customerName}" />
<f:attribute name="attCreditLimit" value="#{creditLimit}" />
<f:attribute name="attDiscountCode" value="#{discountCode}" />
<f:attribute name="attEmail" value="#{email}" />
<f:attribute name="attPhone" value="#{phone}" />
<f:attribute name="attFax" value="#{fax}" />
<f:attribute name="attAddressline1" value="#{address1}" />
<f:attribute name="attAddressline2" value="#{address2}" />
<f:attribute name="attState" value="#{state}" />
<f:attribute name="attCity" value="#{city}" />
<f:attribute name="attZip" value="#{zip}" />
</h:commandButton>
</h:form>

What I am trying to do is passing the value of the inputText tags identified by its id
to the attribute tags putting in the value those id. But it does not work. Those values
are all of them null. The backing bean responses to the request ok, no problem. The
mistake is in the jsf page.

So how do I have to do?

Thanks in advance
Jose

Hello Jose

you can try this:
In index.jsp there is a panel grid with the customer info and you're going to need a h:commandLink tag to get the current customer info and display it in the next jsp. So, we use the h:commandLink and the f:param tags in index.jsp

<h:commandLink action="#{BackingBean.showInfo}" >
<f:param id="id" value="#{item.customerId}" />
<h:outputText value="#{item.customerId}" />
</h:commandLink>

Now in the BackingBean

@EJB
private YourEJBInterface ejb;
private Customer customer;

public String showInfo() {
String action = "show";
//get the parameter value from the link
String customerId = FacesContext().getExternalContext().getParameterMap().get("id");
this.setCustomer(ejb.getCustomerById(customerId));
return action;
}

//getter and setter for Customer object

public Customer getCustomer() {
return customer;
}

public void setCustomer(Customer customer) {
this.customer = customer;
}

Finally in your EJB
@PersistenceContext
EntityManager em;

public Customer getCustomerById(String id) {
Query query = em.createNamedQuery("customer.getCustomerById");
query.setParameter("customerId", Integer.parseInt(id));
Customer customer = (Customer) query.getSingleResult();

return customer;
}

Now, you have the Customer object in your Backing Bean and can display the object's attributes in customerDetails.jsp
like this

<h:panelGrid columns="2" bgcolor="#eff5fa">
<h:outputLabel value="Customer ID:"/>
<h:inputText id="customerId" value="#{BackingBean.customer.customerId}" disabled="true"/>
<h:outputLabel value="Customer Name:"/>
<h:inputText id="customerName" value="#{BackingBean.customer.name}"/>
<h:outputLabel value="Credit Limit:"/>
<h:inputText id="creditLimit" value="#{cBackingBean.customer.creditLimit}"/>
<h:outputLabel value="Discount Code"/>

and so on

Hope this helps

Hi,

Sorry for the late reply because I was trying to whip up the application to share here. Please find in the attached.

The way to do this in NB6.7.1 with JSF1.2 will be slightly different from the article in DZone which is using NB6.8 with JSF2. The way I do it here is as follows:

1) Uses JSPs
2) One Backing Bean for each view and playing around with the Scopes: Application, Session and Request

Your feedback are welcome and hope this helps.

Best regards,

Christopher Lam

I don't have this problem, did you remember to change the TextMessage to ObjectMessage at the sending side? Anyway, you can refer to the attached project, see how it's different from mine.

Hi folks,

I was having problems on update the Customer, but I have resolved.
This is my code snippet,

<h:form>
<h:panelGrid columns="2" bgcolor="#eff5fa">
<h:outputLabel value="Customer ID:"/>
<h:inputText id="customerId" value="#{details.customer.customerId}" disabled="true"/>
<h:outputLabel value="Customer Name:"/>
<h:inputText id="customerName" value="#{details.customer.name}"/>
<h:outputLabel value="Credit Limit:"/>
<h:inputText id="creditLimit" value="#{details.customer.creditLimit}"/>
<h:outputLabel value="Discount Code"/>
<h:selectOneMenu id="discountCode" value="#{details.selectedItem}"
converter="myDiscountCodeConverter">
<f:selectItems value="#{details.selectItems}"/>
</h:selectOneMenu>
<h:outputLabel value="Email:"/>
<h:inputText id="email" value="#{details.customer.email}"/>
<h:outputLabel value="Phone:"/>
<h:inputText id="phone" value="#{details.customer.phone}"/>
<h:outputLabel value="Fax:"/>
<h:inputText id="fax" value="#{details.customer.fax}"/>
<h:outputLabel value="Address (Line 1):"/>
<h:inputText id="address1" value="#{details.customer.addressline1}"/>
<h:outputLabel value="Address (Line 2):"/>
<h:inputText id="address2" value="#{details.customer.addressline2}"/>
<h:outputLabel value="State:"/>
<h:inputText id="state" value="#{details.customer.state}"/>
<h:outputLabel value="City:"/>
<h:inputText id="city" value="#{details.customer.city}"/>
<h:outputLabel value="ZipCode:"/>
<h:inputText id="zipCode" value="#{details.customer.zip.zipCode}"/>
</h:panelGrid>
<h:commandButton id="back" value="Back" action="#{details.list}"/>
<h:commandButton id="update" value="Update" action="#{details.update}"/>
</h:form>

Update method in CustomerDetails backing bean is,

public String update()
{
System.out.println("###UPDATE###");
customer = customerSessionBean.update(customer);
FacesContext context = FacesContext.getCurrentInstance();
context.addMessage(null, new FacesMessage(FacesMessage.SEVERITY_INFO,
"Sucessful", "Record successfully saved!"));
return "SAVED";
}

where the constructor is,

public CustomerDetails() {
try {
InitialContext ic = new InitialContext();
customerSessionBean = (CustomerSessionLocal)ic.lookup("java:comp/env/ejb/CustomerSessionBean");
} catch (NamingException ex) {
Logger.getLogger(ApplicationMBean.class.getName()).log(Level.SEVERE, null, ex);
}
if (customerId == null) {
this.setCustomerId((Integer)FacesUtil.getSessionMapValue("appBean.customerId"));
}
this.fillDiscountCodes();
this.getDetails();
}

This let me call the customer from the jsf instead of details and update.

What I am thinking is in the way to set the dropdown list up exactly on the corresponding value for the selected customer.
I mean if Discount% for Livermore Enterprises is 11.00, in the Customer Detais the ddl must be set on [M(11%)]

I think this is done using javascript. I have to investigate in google.

Regards,
Jose
