Hi Tonie,

A newbie like u here i had the same problems when i started........i found out that it is beacause of the directory structure and the package statement.If you have the statement:

package antlr;

There has to be a corresponding directory 'antlr' which the classes will be placed when they are being compiled. so to compile you should give the command 'javac *.java -d antlr' and it should work.

Hope That helps,

Nur
