    stamper.close
  end
end

Pdf.write

in jRuby and i want to translate to Ruby, using rjb

anyone nows how can i do that?

Solution

It's possible to use libraries like iText from regular Ruby via "RJB", the Ruby-Java bridge. I do not know the proper sequence of calls in RJB to make that happen, but it is possible and I know of folks doing it.

An alternative would be to use the pure-Ruby "prawn" library, which would work the same on both JRuby and Ruby
