I MAY be able to derive something out of the present example given here : http://blog.codeinmotion.com/index.php/2006/12/22/pdf-generation-in-ruby-on-rails/
but this deals with filling out forms. Is there a simpler example that just allows you to talk to itext , send it some plain text and get back a pdf and then send that pdf to the user as downloadable / renderable data?

No I do not want pdfwriter because I already tried it and it is inadequate. It does not have the capabilities I want like putting pushbuttons on the pdf or encrypting them (pdf writer's encryption is broken and removed) but for starters an example would have been nice.

pdf-writer comes with a chunky bacon example if I recall correctly.
You could always 'post-process' a pdf file with pdftk to encrypt it.
Don't know about pushbuttons in pdf's
As far as I know, the rails wiki page on PDF that I linked in the previous e-mail is the exhaustive resource on integrating PDF's with rails.

Are you following my question ? Or do you like to come up with tangential issues ?
I will write up a simple example and put it up myself

#writer.closeStream = false
document.open()
document.add(par.new("Hello World!", font.new(arial)))
document.add(par.new("Now I run on Rails!", font.new(arial))) document.add(par.new("Юникод пашет!!!!", font.new(arial)))
document.close m.close
Cool that is what I was looking for ... I have some of it abstracted to a java class; Do I send m to the render method ?

RJB cant seem to be able to load iText-2.1.2u.jar; where is this placed? I tried placing it the c:/ruby/lib folder then in the lib folder and then in the folder where I was running irb ; then in the jdk's lib and still was unable to locate this jar. it keeps returning nil;
and when I call chunk for example it gives me classdefnotfound etc.

You expect me to install pdf-stamper even though i am not using pdf stamper? and I should install pdfstamper just so I can get to the itext libraries? I dont think that is a good idea, I dont know what everyone else thinks about this.
I tried putting the jars in rjb's ext folder but that didnt work.
I placed jar in the same folder as script. I think any folder in PATH will do. Does any other java lib working? may be problem in jvm version?
Yes String is working for example from the irb interface. I have placed the jar file in script but when I type Rjb::load('iText-2.1.2u.jar') I get an error saying RuntimeError : unknown error from (irb):2: in 'initialize' from (irb):2: in 'dlopen' from (irb):2: in 'load'

Is there a way of sending this pdf file asdasd.pdf to the browser ; Send binary data to the user as a file download as follows :
send_data(BINARY_DATA,{:filename=>"asasd.pdf",:type=>"application/pdf"})
send_data at :
What is BINARY_DATA below? is it document, m, pwf_writer?
BTW I am still unable to load this jar file using rjb ... you are welcome to see here : http://rubyforge.org/forum/forum.php?thread_id=26875&forum_id=8190

I am still attempting to figure out how to send an Itext generated pdf Document to the browser.
I am looking at the following blog posting where someone is using jruby and iText to create a pdf file and then sending it to the browser : http://codersifu.blogspot.com/2007/06/howto-generate-pdf-files-in-ruby-on.html
Unlike the above example I am using only ruby / on rails.
I would like to do precisely this in ROR and I can get to the second last line of the above blog (that is I can generate the document and even the toByteArray or byte ). As in the example:
document.close // <<<--- I can get this document send_data String.from_java_bytes(m.toByteArray), :type=> "application/pdf", :dispostion=>"inline" // I can call the toByteArray and get the array of bytes byte
but I dont know how to send_data to the browser with the document and byetarraystream available.
I try to do a byte.toString() and send that to send_data but when I get byte.toString() from the java classes I get an error :
No Class DefFoundError (org/bouncycastle/asn1/ASN1OctetString)
Where to go from here?
From the blog : Is there an equivalent to String.from_java_bytes in ruby?

Ok following is a posting on blogger about using itext using ROR:
Is there a better blogging site. I cannot format the code properly on this one?
How do I format it nicer?
