Exception in thread "main" java.lang.NoClassDefFoundError:

[Vallone, Philip Mr CTR USA AMC]

Hi List,

I am trying to compile and run the ReplaceString.java example. When I
try to run the jar I get the following message:

 Exception in thread "main" java.lang.NoClassDefFoundError:

Here is my java [comments remove for posting]:
