What version java are you using? What OS?

Assuming Unix/Linux

# java -classpath $WHERE_BE_ANTLR/antlr.jar antlr.Tool t.g

should work.

Also if you have compatilility problems, do

# find antlr -name "*.class" -exec rm {} \;
# javac -g `find antlr -name "*.java" -print`
# jar cvf myAntlr.jar antlr

and then 

# java -classpath $WHERE_BE_ANTLR/myAntlr.jar antlr.Tool t.g

One caveat:

If you use Ric Klaren's version and get an error , then delete the file
