142747 - Setting the response content type in a jsp to application/pdf shows only an empty page.

Status: RESOLVED WORKSFORME

(Core Graveyard :: Plug-ins, defect, P3)

Description

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.0rc1)

If I set the content type of the response object in a jsp to application/pdf and
send a pdf through the response's outputstream, mozilla starts the acrobat
plugin but does not display any content.
The same jsp worked with the 0.9.9 release of mozilla.

Reproducible: Always
Steps to Reproduce:
1.response.setContentType("application/pdf");
2.response.setContentLength(result.length);
3.response.getOutputStream().write(result); // result is byte[]
4.response.getOutputStream().flush();

Actual Results:  Acrobat plugin is loaded but neither the plugin nor any other
content appears on the page.

Expected Results:  Acrobat plugin appears and displays the pdf.

Clicking on a link to a PDF works as one might expect it.

Is there a publicly accessible link where this could be tested, by chance?

Attachment: Logfile produced with NSPR_LOG_MODULES="nsHttp:5" and NSPR_LOG_FILE=... set.

The important part is at the bottom of the file: SupplierProfile.jsp
It is loaded for a first time to display a form, the form is submittet and the
same page reloads, checks for the conditional whether a pdf was requested and
if so uses a <jsp:forward page="./SupplierProfilePDF.jsp"> that serves the
generated PDF.

OK, I attached the dump to the bug.

Ralf, how big is the PDF?  Is the "Content-Length: 4213" correct?

Comment 5

[Ralf Steppacher]

Yes, that is the length of the byte array.

to plugins as a first guess... no idea what could be going wrong here.
