Hi Bruce,
Its seems that the fully qualified Class name is being broken into individual
tokens, which is why (eventually) order is returned as a keyword in an
unexpected location.
I got mine to work (seems ok so far but I haven't completed testing it) by
continuing to consume characters until I encounter a whitespace or its the
end of the query string . I modified the identifier method of the Lexer class
since the idea (i guess) is to identfiy tokens based on word boundries.
So for example my query was broken down into the following tokens
===original===
select
o
from
nz
co
softmetaware
commerce
bo
order <--- and there in lies the problem
o
====modified===
select
o
from
nz.co.softmetaware.commerce.bo.order
o
which seems to work fine. Oh and I had the Class name wrong in the example I
sent below, sorry :-)
