Problem with the import of packets in antlrworks

Have to create a package defined by me, containing some of the classes, and I recall that package in a file .java created of the program AntlrWorks in which i did the import. Package named "com.project开发者_运维技巧.redfox" . I compiled the code with the command: "javac Test.java provaParser.java provaLexer.java" but I get the error that not exist the package.

In the grammar have added :

grammar prova;

@hader{
      import com.project.redfox;
}
....something......

I created the package "com.project.redfox" within of the project redfox developed in NetBeans, therefore the directory com/project/redfox is in the directory redfox.

how can I solve this problem?

To formally answer your question: javac can't find the package com.wikirates which you are probably using in com.project.redfox.

Note that I assumed redfox is a class. If it's a package, you need to import all classes from it like this: import com.project.redfox.*; instead of import com.project.redfox; (assuming that there are classes in com.project.redfox...).
