Hum, as far as I understand the id is considered private in javacc and the code is supposed to perform instanceof checks instead. From what I can see in the code, SimpleNode.getType() is used in a couple of places as an alternative to an instanceof check against the parsed node. So, either of the following could work: - really do perform instanceof checks in the code instead of relying on getType - implement a int getType(Node) utility method that does the instanceof needed and returns the type of the node As a further alternative, you can use reflection to force your way into the id field (you can access private fields by forcing their Field visibility to true at runtime), this would only work in an enviroment where the security manager is not set (or allowing that kind of trickery).
