Error in opening pdf through jsp

[siddharth paul]

In my application when a button is clicked in jsp to open a pdf file,
adobe reader returns the following error -
'There was an error opening the document. The file is damaged and could not be repaired.'


note:- Some time the pdf luckly goes open at 3/10 attempts ratio.

Is this a bug in adobe or any point our application is missing?
Whether this can be a result of load on server?

Use a servlet not a JSP. JSPs are meant to server text resources not binary.

Please read this article for why.

Thanks for the wonderfull article.

I read the part

"Why does everyone tell me to use a servlet to send binary data to the browser? I wanna use a JSP!"

The problem is i can't change the application model because of insufficiant access only can fix the bugs.
Can we sure it's because application is sending binary data to the browser in a jsp?

PDFs are binary, so yes.

Hi,

Go through below links.

An example of using iText to generate a PDF file can be found at http://www.avajava.com/tutorials/lessons/how-do-i-write-to-a-pdf-file-using-itext.html.

An example of serving up a PDF file from a servlet can be found at http://www.avajava.com/tutorials/lessons/how-do-i-serve-up-a-pdf-from-a-servlet.html.

He's not generating PDFs -- just serving existing ones.

The issue is the inappropriate use of JSP to server binary data.
