BeerExpert.java uses unchecked or unsafe operations

[vishwak rajgopalan]

Hello,
I am not sure whether this is the appropriate forum to post this. Please excuse me if I have made an error. I have been using HeadFirst Servlets and JSP and I compiled the BeerSelect.java code (the second version of the controller servlet).
I get the following error message saying that the package com.example.model does not exist. Please help me as I am unsure how to proceed with debugging this issue. I have pasted the error message below


D:\MyProjects\beerV1>javac -d classes src/com/example/web/BeerSelect.java
src/com/example/web/BeerSelect.java:20: cannot access src.com.example.model.BeerExpert
bad class file: .\src\com\example\model\BeerExpert.java
file does not contain class src.com.example.model.BeerExpert
Please remove or make sure it appears in the correct subdirectory of the classpath.
BeerExpert be = new BeerExpert();

Thanks,
Vishwak

Just make sure your pacakge name matches the directory structure that the file is in and that your filename matches the class name of your class's signature.

Looks like you're compiling it as src.com.etc.etc rather than com.etc.etc, as below. Not a stupid question, we've had this question a couple of times so I'll point it out to Bert and Kathy, maybe they can look at polishing these instructions in the next edition!

> cd src
> javac -d ../classes com/example/web/BeerSelect.java
