Problema deploy tomcat servlets

Olá a todos. Procurei por problema parecido com o meu e não achei a solução…

Seguinte, estou tentando fazer o deploy de uma aplicação em uma máquina teste aqui, mas não está funcionando.

Quando tento acessar http://localhost:8080/first-web-study/teste dá HTTP Status 500.

Exception:
javax.servlet.ServletException: Wrapper cannot find servlet class java.com.FirstServlet or a class it depends on

Estou usando uma task ant para a tarefa… Segue o web.xml e o build.xml que estou usando

</project>

Alguém sabe qual é o problema ai?

Código da servlet

package java.com;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class FirstServlet extends HttpServlet {
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {

		PrintWriter out = resp.getWriter();

		out.println("<HTML>");
		out.println("<BODY>");
		out.println("<h1> TESTE</h1>");
		out.println("First exercise with servlets");
		out.println("</BODY>");
		out.println("</HTML>");
	}
}

Desde já obrigado!!
