Put newlines in your query. (At the beginning or end of your strings.)
Print it out or look at it in an editor, especially if it can show
line numbers.
Then you can see where the problem is it will likely be obvious
how to fix it.

Re: SPARQL QUERY STRING VARIABLES
FYI attachments are not permitted on this list
What Chris and Andy are suggesting is that you print out your string after
constructing it e.g.
System.out.println(querys);
Secondly if you follow their suggestions and add new lines to your query
the error message will point you more directly to the point in the query
where the error occurs. Currently your query is one single line hence why
the error message reports an error at line 1, column 331.

Re: SPARQL QUERY STRING VARIABLES
The problem is that when the variables of type String get well, they need
some quotes and to insert them into the query as + b + does not know
how to attach the quotes.
\n FILTER (regex(str(?g),*+g+*)) . +
is
\n FILTER (regex(str(?g),Rodillo)) . +
and shourd be:
\n FILTER (regex(str(?g),Rodillo)) . +
Thank you,

You'll have to put the quotes in yourself.
I suggest writing a method `quote` which quotes strings: to begin with
static String quote(String x) {
return \ + x + \;
}
and then you can write
\n FILTER (regex(str(?g),*+quote(g)+*)) . +
of course this breaks as soon as `g` might contain quotes or
backslashes, in which case I suggest
return \ + FmtUtils(stringEsc(x, true) + \;
which is a method from ARQ that properly quotes strings for SPARQL.
