hELLO erik,
ok i got it by using ant:filterchain in a sample defined..
i used as substitution file for properties my project.properties..
i was curious on one thing though it could be off-topic since it's ant-related
question..
seems to me that filterchain works only when you copy files
if i put a token @DB_DRIVER@ in my source java file, will ant replace it
althought i am not copying files?
thanks and regards
marco
