When I run my Servlet in Eclipse , this error occurs:
"The type java.io.ObjectInputStream can not be resolved. It is indirectly referenced from required .class files"
For the web application to be executed, I downloaded Apache-Tomcat 7.082 and added it to Eclipse , I use the Eclipse for Java EE , I have the JRE 8.151 .
The code is as follows:
import java.io.PrintWriter;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
* Servlet implementation class Mostrarunmensaje
*/
@WebServlet("/Mostrarunmensaje")
public class Mostrarunmensaje extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public Mostrarunmensaje() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head></head>");
out.println("<body>");
out.println("<h1>Probando un servlet</h1>");
for(int f=1;f<=10000;f++) {
out.println(f);
out.println(" - ");
}
out.println("</body>");
out.println("</html>");
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}
}
Thank you very much
