Please help me to resolve this problem

Hi divya,

Do you have package com.example.model in your application?
Do you have class BeerExpert? If so, where it is located?

This is a javac/classpath issue.
The best place to go for help with such issues is the Java In General (Beginner) forum.

Moving...

It would be helpful if you replied to Ludmila's questions first.

"Please reply to resolve the problem"

How about answering Ludmila's questions, so that we can help you further.

Yes , I do have a "BeerExpert"
Path : C:\Java Prog\Servlet\MyProject\beerV1\src\com\example\model\BeerExpert.java

and it code is on my last post

Thanks
Divya

We also would appreciate it if you would list the source of where this code came from. Aside from copywrite issues, it's just plain polite. Especially since many of those authors hang out here.

I'm pretty sure this code came from the "Head First" book, yes?

Is the 'C:\Java Prog\Servlet\MyProject\beerV1\src' directory in your classpath ?

thanks for you reply...

Well Yes this is a code from HEAD First Servlet.

Well That's the path where the "BeerExpert.java" saved

ClassPath :.;C:\j2sdk1.4.2_13\lib
Java_home : C:\j2sdk1.4.2_13
Path :.;C:\j2sdk1.4.2_13\bin

Thanks
Divya

Joanne Neal: "Is the 'C:\Java Prog\Servlet\MyProject\beerV1\src' directory in your classpath ?"

divya sharma: "ClassPath :.;C:\j2sdk1.4.2_13\lib"

Put C:\Java Prog\Servlet\MyProject\beerV1\src in the CLASSPATH as Joanne suggests.

Well it still not work... same error after putting same path on ClassPath

first compile BeerExpert.java and then compile the servlet

I have done the same. No error while complieing "BeerExpert" but while compling "BeerSelect" it show an error coz it's unable to call BeerExpert.

navigate to your "src" folder and ,try compliing with this command

javac -classpath . com/example/web/BeerSelect.java
