I am a biginner in the FPO arena.
Did you try searching the Apache FOP web site, just a thought, I am sure you did your home work.

Where is WilliamB when we need him?

Sounds like you have a problem with caching to me!

1. Have you tested it with other PC's ?
2. how does your url look like ? does it have a .pdf string at the end ?
3. are you supplying the xml and xsl at the url or inside your java xsl transformation code ?

As I recall, PDF plugins like to have a content-length to work with. It sounds like you are generating PDF output directly to the response stream so you can't set the content-length.

If this was my problem I would write the pdf to a temp file in order to be able to send the content-length correctly. That also helps with debugging the FOP since you can have the server side keep the temp file as you develop the application. I also like to keep the .fo output around during development so you can see what is being generated.

In general, I try to develop servlet applications in parts that can be tested OUTSIDE the servlet environment as much as possible - servlets have so many pitfalls.

Thank you all for the replies.

I am not able to understand why i need to refresh a lot.
I am executing my code through WSAD. The URL is
http://localhost:9080/PDFOutput/TestingServlet
Here is my Servlet code, that is used to generate the pdf document.
Here i am passing xml as String.



And here is my details.xsl file.


Any help would be greatly appreciated

Thanks in Advance.

Add this few lines to your servlet code after the codeline MessageHandler.setScreenLogger(logger);


resp.setContentType("application/pdf");
resp.setHeader("Content-Disposition","inline;filename=details.pdf ");

and see how its works.

Instead of writing it to outputstream, try to write it to a bytearrayoutputstream and then assign it to printwriter. (by this way you can get the content length of your file then you can set the response length using resp.setContentLength(bytearrarycontent.length)
 
Don't get me started about those stupid light bulbs.
