ActionServlet return a pdf document
Hello,
I am trying to generate a PDF document on the fly based on dynamic jsp
generation comming from BroadVision.
I am making use of an struts action class,which genreates the required PDf
file.When i try to open the PDF file I get the error as
There was an error opening this document.Could not repair this file
If i run the same application in Tomcat it works fine.
This is by java code.
public class PDF extends Action
{
public ActionForward perform(ActionMapping mapping, ActionForm
form,HttpServletRequest request,HttpServletResponse response) throws
IOException, ServletException
{
try
{
Document document = new Document();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PdfWriter.getInstance(document, baos);
document.open();
document.add(new Paragraph(Hello World));
document.close();
response.setContentType(application/pdf);
response.setContentLength(baos.size());
ServletOutputStream out = response.getOutputStream();
baos.writeTo(out);
out.flush();
}
catch (Exception e2)
{
System.out.println(Error in +getClass().getName()+\n+e2);
}
return null;
}
}//end of class
Please look into this matter.
Thanks regards
Arun

ActionServlet return a pdf document
Hi,
I am trying to generate a PDF document on the fly based on dynamic html
generation comming from BroadVision.
I am using a tool called HTMLDOC that can use as input parameter a html file
or a URL.
If i used this tool directly from the command line,
htmldoc URL -f result.pdf
then, the pdf generation is fine, includig images.
But if i called this via an action, and i get the ouput of the tool and send
it to the response, the pdf result is not displayed if i used the image tag
in the HTML.
This is the java code for my action :
Process process;
Runtime runtime;
java.io.InputStream input;
byte buffer []; // Buffer for output data
int bytes; // Number of bytes
command = the called to my tool with the options and the URL :
/opt/htmldoc http://www.myfile.jsp
runtime = Runtime.getRuntime();
try
{
process = runtime.exec(command);
input = process.getInputStream();
buffer = new byte[8192];
while ((bytes = input.read(buffer)) 0)
outputStream.write(buffer, 0, bytes);
return (process.waitFor());
Any idea or suggestion ???
Thanks in advance
Regards,
ignacio

Just handle the output of the pdf by yourself and return null for your
Action.

RE: ActionServlet return a pdf document
Hi,
i return null for the action, i did not paste the complete code for the
action.
What do you mean by handling the output of the pdf by myself?
I don't want to save the pdf file into the file system, i want to send
directly to the response the output of the call the the tool.

RE: ActionServlet return a pdf document
I'm looking for an HTML to PDF tool that I can run Server-side from a
Servlet. It needs to take an HTML page and create a PDF.
I checked out HTMLDOC but I don't think the command line version is free.
Are there any others available for free?

hi,
i think that htmldoc is free of charge

you could also use Html2pdf_asp

Re: ActionServlet return a pdf document
Hi,
I had a similar problem with an RTF document generation on the fly.
The only thing it is working fine for Netscape but the IE is not opening it
as word
document because of extension it has got. .do
I eliminated it by introducing another mapping similar to .do as .rtf
in Web.xml
Hopefully you also create the similar mapping and call the action as
action.pdf instead
of action.do

Re: ActionServlet return a pdf document
I am about to do a similar thing Rendered JPEG images. Sending back binary content should be possible from Struts Action. In the action perfrom() you return `null' to signify that you handling the response by yourself. Generating custom response is the same, then, as a Java Servlet. You have to set content type. For you it would be response.setContentType(text/pdf) or whatever the MIME type is pdf is. Then you have to get reference to the ServlketOutputStream ServletOutputStream out = response.getOutputStream(); Buffer it up and send your binary (PDF) stream down stream. Dont forget to flush(). That should be it unless any body knows otherwise. -- Peter Pilgrim ++44 (0)207-545-9923 //_\\ Mathematics is essentially the study of islands of === disparate subjects in a sea of ignorance. || ! || Andrew Wiles _ Message History From: IZAGA,IGNACIO (HP-Germany,ex1) [EMAIL PROTECTED] on 14/11/2001 13:01 CET --MCIT Hi, I am trying to generate a PDF document on the fly based on dynamic html generation comming from BroadVision.
