Getting NoClassDefFoundError running java on command line

Trying to run a java program from the command line on windows 7. Here's the back file I'm using:

set javahome=C:\progra~1\java\jdk1.6.0_18
set classpath=.;%javahome%;C:\dev\java\ServiceTest\com\roeschter\jsl
set PATH=%PATH%;%javahome%\bin
java -classpath "%classpath%" TelnetEcho

My current directory is c:\dev\java\ServiceTest which contains the compiled file TelnetEcho.class. Here is the full error message:

C:\dev\java\ServiceTest>java -classpath ".;C:\progra~1\java\jdk1.6.0_18;C:\dev\j
ava\ServiceTest\com\roeschter\jsl" TelnetEcho

Additional info:

There is a package line in the TelnetEcho.java file -
package com.roeschter.jsl;

I tried having the TelnetEcho.class file in both of the following directories:

C:\dev\java\ServiceTest
&
C:\dev\java\Service\Test\com\roeschter\jsl

But to no avail.

You need

set classpath=.;C:\dev\java\ServiceTest

I tried adding C:\dev\java\ServiceTest to the classpath but still getting same error. I didn't think it would make a difference since I'm running the java command from C:\dev\java\ServiceTest and that directory is already covered in the classpath with the dot(.).

C:\dev\java\ServiceTest>java -classpath ".;C:\dev\java\ServiceTest;C:\progra~1\j
ava\jdk1.6.0_18;C:\dev\java\ServiceTest\com\roeschter\jsl" TelnetEcho

Yup I needed to prepend the class name with com.roeschter.jsl.
