That there are friends I have a problem with Tomcat when trying to run a Servlet where I have a query for a shopping cart send me the following error
java.lang.UnsupportedOperationException: Not supported yet.
Modelo.DetalleVenta.<init>(DetalleVenta.java:20)

Controlador.ServletControlador.processRequest(ServletControlador.java:40)

This is my code in html and it's fine that I think, and I guess it's the server's problem they could help me.
