Trouble with Selenium (XercesImpl) and Google App Engine

I downloaded selenium-java-2.0b3.zip from the Selenium Downloads page. I unzipped it and added all the .jars to the build path of a simple Eclipse project:

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;


public class Main {
    public static void main(String[] args) {
        WebDriver driver = new HtmlUnitDriver();
        driver.get("http://www.google.com");
        System.out.println(driver.getPageSource());
    }
}

This works fine. I then try to do add all the libraries to the build path of a GWT/GAE project. Without adding any code that references the libraries, I see these errors when I try to run the project:

What am I doing wrong?

Copy all the jars in the Selenium download to war/WEB-INF/lib and add them to the build path.
