布局未显示在前端模块magento上

在magento模块中，布局没有用前端加载时出现了一些问题。

config.xml

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Way_SaleWithus>
            <version>1.0.0</version>

            </reference>
        </SaleWithus_index_index>
    </layout>

SaleWithus.phtml定位应用程序/design/frontend/base/default/template/SaleWithus.phtml

<div>
<h4>Hello World!!</h4>
</div>

IndexController.php

<?php
class Way_SaleWithus_IndexController extends Mage_Core_Controller_Front_Action
{
    public function indexAction()
    {
//         if ($this->_getSession()->isLoggedIn()) {
//            $this->_redirect('*/*/');
//            return;
//        }
//        $this->getResponse()->setHeader('Login-Required', 'true');
//        $this->loadLayout();
//        $this->_initLayoutMessages('customer/session');
//        $this->_initLayoutMessages('catalog/session');
//        $this->renderLayout();
        $this->loadLayout();
            $this->renderLayout();
            echo "subhash";
    }
    protected function _getSession()
    {
        return Mage::getSingleton('customer/session');
    }
}
?>

代码哪里出了问题？
