running RabbitMq in CMD - eclipse

Question

I'm currently doing the tutorials that can be found on the rabbitMQ webiste and I've run into problems when running the programs in command prompt (Windows7).
Now I have the client libraries working perfectly in Eclipse i.e. I'm able to send messages between a producer and consumer etc. But if I try to run this program in command prompt I get this:
Worker.java:1: error: package com.rabbitmq.client does not exist
import com.rabbitmq.client.Channel;
^
Worker.java:2: error: package com.rabbitmq.client does not exist
import com.rabbitmq.client.Connection;
^
Worker.java:3: error: package com.rabbitmq.client does not exist
import com.rabbitmq.client.ConnectionFactory;
^
etc...... etc..... (this list goes on)....
Now I have added the necessary library (.jar files) locations to the classpath! and compiling in the command prompt using:
javac -cp rabbitmq-client.jar Worker.java
but i'm still getting these issues. If anyone can help I would be most grateful.
Cheers!

I had a similar problem when trying to get RabbitMQ's sample rabbitmq-java-client running (Netbeans on a linux machine). Even though the code in Netbeans said the packages were there, running mnv install or javac would produce tons of errors like:
Send.java:11: error: package com.rabbitmq.client does not exist import
com.rabbitmq.client.ConnectionFactory;
I solved it fixing the structure of the directories. They should look like this:
my-app
|-- pom.xml
`-- src
|-- main
| `-- java
| `-- com
| `-- mycompany
| `-- app
| `-- App.java
`-- test
`-- java
`-- com
`-- mycompany
`-- app
`-- AppTest.java
Please see: http://maven.apache.org/guides/getting-started/index.html#How_do_I_make_my_first_Maven_project
I think that matches what Maven is looking for.
Also, I rebuilt the pom by hand. The pom in the sample rabbitmq-java-client lacks all this information:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
It just has
<?xml version="1.0"?>
See:
https://github.com/rabbitmq/rabbitmq-java-client/blob/master/pom.xml
Actually, I'm wondering why the poster is doing this in Eclipse.
Now I'm guessing here, but his Worker.java does not need to be edited in an IED. I wonder if we both made the same mistake.
They don't need to be. Just put them in their own directory with these files
commons-cli-1.1.jar
commons-io-1.2.jar
rabbitmq-client.jar
Then
javac -cp rabbitmq-client.jar Worker.java
Open RabbitMQ server (http://localhost:15672/) then
java -cp .:commons-io-1.2.jar:commons-cli-1.1.jar:rabbitmq-client.jar Send
next
java -cp .:commons-io-1.2.jar:commons-cli-1.1.jar:rabbitmq-client.jar Recv

This is from: https://www.rabbitmq.com/tutorials/tutorial-one-java.html
The Java client library
RabbitMQ speaks AMQP, which is an open, general-purpose protocol for
messaging. There are a number of clients for AMQP in many different
languages. We'll use the Java client provided by RabbitMQ.
Download the client library package, and check its signature as
described. Unzip it into your working directory and grab the JAR files
from the unzipped directory:
$ unzip rabbitmq-java-client-bin-.zip $ cp
rabbitmq-java-client-bin-/*.jar ./ (The RabbitMQ Java client is also
in the central Maven repository, with the groupId com.rabbitmq and the
artifactId amqp-client.)
