Class Not found error

Hi,

I am following instructions for example wordcount version 2 execution on Hadoop installed
under Cygwin. The quick start example worked fine. But word count version 2 is giving following
error:

java.lang.ClassNotFoundException: org.myorg.WordCount
 at java.net.URLClassLoader$1.run(URLClassLoader.java:200)

 at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:79)
 at org.apache.hadoop.mapred.JobShell.main(JobShell.java:68)

I checked all files many times in HDFS. They are all in there.

Please help..
