from local server to remote server
Hi, I am develop an small app in servlets an d it works in local with derbi, but now I want work in a remote server then I have upload the app and I have change the nameClass in my DAO file. The thing is that in the web.xml I have write the code below:

<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<servlet-name>ServletTienda</servlet-name>
<servlet-class>controlador.ServletTienda</servlet-class>
</servlet>

and when I run the remote server I get the next trace:

Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

Most likely cause is that the class file is missing.
