Re: [Info-gnuprologjava] few questions about your package

[Daniel Thomas]

How exactly is it not working properly?

I won't compile as 'label.getText()"."' is invalid and you don't need to
add in "." like that which might be the problem you are getting when you
create the goalTerm as you put a . in when you don't need to. The the
CompoundTerm is not being correctly constructed as the first argument is
the functor and so should just be "read_words" without any brackets or
arguments - that is what args is for.

I hope that helps,

Daniel
