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](http://codersifu.blogspot.com/2007/06/howto-generate-pdf-files-in-ruby-on.html)

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 :

```
document.close <<<--- I can get this document and the m

```

bytearraystream  
send\_data String.from\_java\_bytes(m.toByteArray),  
:type=\> “application/pdf”, :dispostion=\>“inline”

## but I dont know how to send\_data to the browser with the document and byetarraystream available.

is there an equivalent to String.from\_java\_bytes in ruby?

I think I may have figured this out.

to pass data to the send\_data method you just need to send it the  
.toByteArray() output and no need to do a String.from\_java\_bytes!!

So I can bypass the from\_java\_bytes in my case…
