Passing Values from page to other page JSF

Question

I am beginner in java server faces (JSF), I need to pass the content of text input to second page to display it, the same applies for the second page: I want to pass radio buttons values to a third page. I searched and tried a lot without success. For example I tried

 <h:commandButton value="Next" action="#{myBean.execute(input_id.value)}"/>

Execute method is:

public void execute(String value) {
// ...

    try{
         FacesContext.getCurrentInstance().getExternalContext().dispatch("/Quizy.xhtml?faces-redirect=true");
    }
    catch(Exception e){
        System.out.println("err");    
    }  
}

Any suggestions?

There are several ways for doing this, but here is one of them. You will need to save the inputText value into a property of your bean and both your h:inputText and your h:commanButton should be in the same h:form element

Here is a sample code

In your view

<h:form>
    ...
    <h:inputText value={myBean.someValue} />
    ....
    <h:commandButton value="Next" action="#{myBean.execute()}"/>
</h:form>

Your managed bean should be at least session scoped if you want your property (someValue) to be available in different pages. The content of the managed bean should look like this also:

private String someValue;

// Getter and setter for `someValue`

public String execute() {
    // ...
    return "/Quizy.xhtml?faces-redirect=true";
}

In the second page if you want to retrieve that value, just use #{myBean.someValue}
