HTTP Status 405 - HTTP method GET is not supported by this URL

estou mandando os códigos

no arquivo web.xml:

[code]

<display-name> GetNpostServlet </display-name>

<description> Testando exemplo core j2me </description>

<servlet>
	<servlet-name>GetNpost Servlet</servlet-name>
	<servlet-class>GetNpostServlet</servlet-class>
</servlet>

<servlet-mapping>
	<servlet-name>GetNpost Servlet</servlet-name>
	<url-pattern>/GetNpostServlet</url-pattern>
</servlet-mapping>

[/code]

depois no arquivo java:

[code]import java.util.;
import java.io.;
import javax.servlet.;
import javax.servlet.http.;
import java.sql.*;

public class GetNpostServlet extends HttpServlet
{
protected void doGET(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
{
String acct = req.getParameter(“account”), pwd = req.getParameter(“password”);
String balance = accountLookup(acct, pwd);
if(balance == null)
{
res.sendError(res.SC_BAD_REQUEST, “Não foi possível localizar a conta…”);
return;
}
res.setContentType(“text/plain”);
PrintWriter out = res.getWriter();
out.print(balance);
out.close();
}

protected void doPOST(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
{
	String acct = req.getParameter("account"), pwd = req.getParameter("password");
	String balance = accountLookup(acct, pwd);
	if(balance == null)
	{
		res.sendError(res.SC_BAD_REQUEST, "Não foi possível localizar a conta...");
		return;
	}
	res.setContentType("text/plain");
	PrintWriter out = res.getWriter();
	out.print(balance);
	out.close();
}

private String accountLookup(String acct, String pwd)
{
	Connection con = null;
	Statement st = null;
	StringBuffer msgb = new StringBuffer("");
	try
	{
		Class.forName("com.mysql.jdbc.Driver");
		con = DriverManager.getConnection(" ", " ", " "); 
		Statement stmt = con.createStatement();
		ResultSet rs = stmt.executeQuery("select balance from acctInfo where account = " + acct + " and password = '" + pwd + " ' ");
		if(rs.next())
			return rs.getString(1);
		else
			return null;
	}
	catch(Exception e)
	{
		return e.toString();
	}
}

public String getServletInfo()
{
	return "GetNpostServlet 1.0 - www.corej2me.com";
}

}[/code]

Severe: Parse Error at line 5 column 17: Document root element ?web-app?, must match DOCTYPE root ?null? Org.xml.sax.SAXParseException: Document root element ?web-app?, must match DOCTYPE root ?null?.

E mais pra frente aparece
