I have a working JSF application that allows a user to enter their name, press the Submit button, and they are presented with a page that welcomes them.

The structure is very simple, there is a Person bean that has a setter and getter for a name, and the textfield sets the name, and the welcome page gets the name from the bean to present it on the welcome page.

My question is can I invoke java methods from XHTML when the user presses the Submit button, because I need to open a connection to the database. The code for the first page of the application looks like this in the xhtml file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html">

<h:head>
 <title>JSF 2.0 Hello World</title>
</h:head>
<h:body>
 <h3>JSF 2.0 Hello World Example - hello.xhtml</h3>
 <h:form>
  <h:inputText value="#{helloBean.name}"></h:inputText>
  <h:commandButton value="Welcome Me" action="welcome"></h:commandButton>
 </h:form>
</h:body>
</html>

So it looks like when they hit Welcome Me, the welcome.xhtml file is called up and the bean is passed to it. But I also need to execute some code to open the database when the Welcome Me button is pressed, how can I do this?

    For that, the action attribute of the command button should be bound to the action method of the bean.

    <h:commandButton value="Welcome Me" action="#{helloBean.submit}" />

    In the method you’ve all the freedom to write down Java code which should be executed when the button is pressed.

    public String submit() {
    // ...

    return "welcome";
}

    The returned string will be used as navigation outcome. If you return null or void, it will return to the same view.
