prawnto with jruby && env[SERVER_PROTOCOL] == nil

Reported by hnguyen (at co.brazos.tx) | March 31st, 2009 @ 02:36 PM

I was testing on loading a prawn page under jruby and i get this error

ActionView::TemplateError (undefined method downcase' for nil:NilClass) on line [#1](/projects/23449/tickets/1 "Ticket #1") of app/views/questions/download_pdf.pdf.prawn: 1: pdf.font "#{Prawn::BASEDIR}/data/fonts/comicsans.ttf" 2: pdf.text "hello" 3: pdf.text "hello"

vendor/plugins/prawnto/lib/prawnto/template_handler/compile_support.rb:34:in `ssl_request?'

gems/gems/actionpack-2.2.2/lib/action_view/base.rb:256:in `render'

so in vendor/plugins/prawnto/lib/prawnto/template_handler/compile_support.rb file i commented out set_pragma and set_cache_control under the set_header method and voila it works. the error is coming from ssl_request?. it cannot get the environment variable. o and i was using ssl on a j2ee server

    just letting you know i changed the ssl_request? method to this so that i can still have it working without me commenting out the code.

    def ssl_request? if defined?(JRUBY_VERSION)

    @controller.request.env['javax.servlet.request.cipher_suite'].nil?

    else

    @controller.request.env['SERVER_PROTOCOL'].downcase == "https"

    end end memoize :ssl_request?

    it checks if it is running on jruby and if it does then glassfish would set the javax.servlet.request.cipher_suite env variable to any ssl cipher if using ssl, else it would not exist. im not sure if other j2ee servers do it differently.

    I noticed that rack.url_scheme is set to https instead, so here is what worked for me:

    def ssl_request?
  is_ssl_protocol_var_set = @controller.request.env['SERVER_PROTOCOL'] || @controller.request.env['rack.url_scheme']
  is_ssl_protocol_var_set and is_ssl_protocol_var_set == "https"
end

    correction:

    def ssl_request?
  ssl_protocol_var_set = @controller.request.env['SERVER_PROTOCOL'] || @controller.request.env['rack.url_scheme']
  ssl_protocol_var_set and ssl_protocol_var_set.downcase == "https"
end
