HTML is not PDF. Just because you tell the browser that you're sending it PDF, isn't going to transform HTML into PDF. You need to generate a real PDF format. There are a number of 3rd party libraries to do this. Do a google search for them.

And just to make it abundantly clear, a PDF is a binary document rather than a text one.

As such requests for PDF documents should be handled by a servlet rather than a JSP, as the JSP will add whitespace into the response potentially corrupting it.

Hi i wrote the coding with the help of "IText", a free java library which i got from internet....

the code now i am using is...




This is working fine...but while using this code the pdf documnet get created and stored in the location which i specified..

PdfWriter.getInstance(document,new FileOutputStream("C:/palanivelrajan/ValidData.pdf"));

but what my actual need is to create document and to ask user "save or open"....we have to give the option for storing the document where he needs to save..

what to do for that....

  • The iText version you're using (iText 5) is covered by the GNU Affero license, which makes it non-free for most business uses. Make sure you (and your company's lawyer) understand what that means.
  • You should not use JSPs for doing this kind of stuff; that's what servlets are for. Java code has no place in JSPs.
  • You need to stream the PDF data to the client in order to get the Save/Open option; search for "streaming binary data from a servlet" or some such phrase. This has been discussed multiple times in these forums.

    The advice given by Bear, Stefan and Tim is spot on: 1) Don't use JSPs for stuff like this, because it's really bad design. 2) Don't use JSPs for stuff like this, because it is very likely not to work.
