    Default How can I export elements in array to .xhtml

    Hi all,

    I'm working with simple project using JSF is: Brandi's Bagel House. Everything is OK. And now I want to present elements that the user choice like: Bagel, Topping, Coffee... onto Receipt.xhtml. But I don't know how to do because a data type of selectedToppingNames is an Array.
    Please help!

    Here is my code:

    Index.xhtml:

    Default Re: How can I export elements in array to .xhtml

    Here's what is BASICALLY the problem:
    You're having topping point to the array itself, not the items inside of it. Instead of calling indexBean.selectedToppingNames try making a method within your java code to get all of the items in the topping array. Here is an example:

    public String getToppingNames(){
    String toppingNames = "";
    for(int i = 0; i < selectedToppingNames.length(); i++){
    toppingNames+=selectedToppingNames[i]+"\n";
    }

    }

    Hope this helps!

    Thank you upfish... From your ideas I think my problem has solved. I'm try making a method getToppingNames() to get items and value from an array.

    Here is my code in IndexBean.java:
    ........
    ........
    public void setSelectedToppingNames(Topping[] selectedToppingNames) {
    this.selectedToppingNames = selectedToppingNames;
    }

    private double computeTopping() {
    double acc = 0.0;
    for (Topping eachName : selectedToppingNames) {
    acc += eachName.getVal();
    }
    return acc;
    }

    public String getToppingNames() {
    String toppingNames = "";
    for (Topping eachName : selectedToppingNames) {
    toppingNames += eachName.getItems() + "\n" + eachName.getVal() + ";" + "\n" + "\n";
    }
    return toppingNames;
    }

    }

    And... in receipt.xhtml:
    ...........
    ...........
    Bagel :
    <hutputText value="#{indexBean.selectedBagelName.items}"/>
    <hutputText value="#{indexBean.selectedBagelName.val}">
    <f:convertNumber type="currency"/>
    </hutputText>

    Topping :
    <hutputText value="#{indexBean.toppingNames}"/>
    <h:panelGroup/>

    Coffee :
    <hutputText value="#{indexBean.selectedCoffeeName.category}"/>
    <hutputText value="#{indexBean.selectedCoffeeName.prices}">
    <f:convertNumber type="currency"/>
    </hutputText>

    <h:panelGroup/>
    .........
    .........

    And... this my result after click compute Button:
    Receipt
    Bagel : White $1.25
    Topping : Butter 0.25; Peach jelly 0.75;
    Coffee : Decaf Coffee $1.25
    Subtotal : $3.50
    Tax: $0.21
    Total: $3.71

    But how to bring items and value of Topping down the line... like this:
    Bagel : White $1.25
    Topping : Butter 0.25 (And how to attached $ symbol in 0.25 of an array?)
    Peach jelly 0.75
    Coffee : Decaf Coffee $1.25
    Subtotal : $3.50
    Tax: $0.21
    Total: $3.71


    Thank you upfish... And thank you all of you.
