I had struggled with this issue and wanted to help provide a unique solution and insight.

Certain AJAX based frameworks will inject javascripts and stylesheets at the beginning of the and doing this seems to prevent the well-established meta tag solution from working properly. In this case I found that directly injecting into the HTTP response header, much like Andras Csehi's answer will solve the problem.

For those of us using Java Servlets however, a good way to solve this is to use a ServletFilter.

public class EmulateFilter implements Filter {

@Override
public void destroy() {
}

@Override
public void doFilter(ServletRequest arg0, ServletResponse arg1,
        FilterChain arg2) throws IOException, ServletException {
    HttpServletResponse response = ((HttpServletResponse)arg1);
    response.addHeader("X-UA-Compatible", "IE=8");
    arg2.doFilter(arg0, arg1);
}

@Override
public void init(FilterConfig arg0) throws ServletException {
}

}
