HTTP Status 500 - Chapter 3 HFJS

[Varalakshmi Ramanarayan]

Hi Ranchers!!

I am trying to do the program explained in Chapter 3 of HFJS. However I am struck in deployment of version 2. I have created the directoty structure as explained in the book.I have created and compiled the BeerExpert.java file. For BeerSelect.java I have used the following commamd line and it compiles fine.

 C:\Varu\WEBJavaLearning>javac -classpath tomcat\common\lib\servlet-api.jar;classes;BeerV1\classes;. 
-d BeerV1\classes BeerV1\src\com\example\web\BeerSelect.java 

But when I try to deploy it in Tomcat it is giving me HTTP Status 500 error(The form.html page works fine, From that page if I click submit button I get this error). The error statement is as below.

type Exception report
 
message
description The server encountered an internal error () that prevented it from fulfilling this request.
 
exception
javax.servlet.ServletException: Servlet execution threw an exception
 
root cause 
java.lang.NoClassDefFoundError: BeerV1/src/com/example/model/BeerExpert
com.example.web.BeerSelect.doPost(BeerSelect.java:22)
javax.servlet.http.HttpServlet.service(HttpServlet.java:710)
javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
 
note The full stack trace of the root cause is available in the Apache Tomcat/5.5.26 logs. 

On the 22nd line of my BeerSelect.java file is the line -- BeerExpert be = new BeerExpert();

Some one please help me with this!!
Thanks in advance.

BeerV1/src/com/example/model/BeerExpert

Shouldn't that be com/example/model/BeerExpert instead ? In what package is BeerExpert ? And check the import in BeerSelect.java.

Thanks for the help Christophe..

Shouldn't that be com/example/model/BeerExpert instead ?

I am sorry I did not get where should com/example/model/BeerExpert go..
Basically my servlet is not able to find the model(BeerExpert)in my application. I am not able to figure out why..
Here are the details you asked for.

path to BeerExpert.java is
C:\Varu\WEBJavaLearning\tomcat\webapps\Beer-V1\WEB-INF\classes\com\example\model\BeerExpert.java

path to BeerSelect.java is
C:\Varu\WEBJavaLearning\tomcat\webapps\Beer-V1\WEB-INF\classes\com\example\web\BeerSelect.java

Import statment in BeerSelect is import com.example.model.BeerExpert;
Package Statment of BeerExpert is package com.example.model;

Thanks again!!

Mmmh... everything looks fine. Are you sure you did not leave an old .class file in your classes directory ? Try to remove BeerSelect.class and BeerExpert.class, and recompile them.
