hi 2 all,
I have made a simple LoginServlet, which just call a method validate() of a class Customer. Although that class Customer is placed in the lib folder of my web application as a jar file .
But when i try to use this class in that servlet LoginServlet, it shows an error that message.
" The server encountered an internal error () that prevented it from fulfilling this request. "
javax.servlet.ServletException: Invoker service() exception
at org.apache.catalina.servlets.InvokerServlet.serveRequest(
at org.apache.catalina.servlets.InvokerServlet.doGet(
at javax.servlet.http.HttpServlet.service(

root cause :
java.lang.NoClassDefFoundError: com/retail/controller/Customer
Although jar file of complete package which contains class Customer is placed in the lib of web-inf of my web application.
I think that servlet container is not able to load that jar file. But how this problem could be solved?
Plz reply me ASAP.
