Android Prevent Screen From Turning Off

So I saw that you can make an xml that does LinearLayout like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:keepScreenOn="true">
</LinearLayout>

My question is: I am doing a jQuery Mobile app, and I thought I could just put this in my web.xml file. However, I keep getting errors when I try to do so. Here is my web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<!-- The definition of the Root Spring Container shared by all Servlets 
    and Filters -->
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring/root-context.xml,
        /WEB-INF/spring/appServlet/security-context.xml</param-value>
</context-param>

<!-- Creates the Spring Container shared by all Servlets and Filters -->

<listener>
    <listener-class>org.springframework.security.web.session.HttpSessionEventPublisher</listener-class>
</listener>

        <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>
<filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

Is there an easier way to make it so my Android tablet will not turn off the screen while I am in the web application? Like I said, I tried just putting the LinearLayout code into my web.xml, and it gave me a ton of errors. Thanks.

It is not possible. In fact, it would be seriously disturbing if an arbitrary Web site could affect a device that way.

If you elect to create a native app, or perhaps even a PhoneGap app, then you can consider trying to control whether or not the screen turns off.
