[iText-questions] PdfReader error
I'm trying to take a pdf that I have stored in an oracle database and to then use iText to alter the pdf then output it as stream to a web client. I'm trying to do this without using any files, only streams. The problem I have is that although I appear to be getting the stream of the oracle blob; when I try to convert it to a byte[] I get this error: java.io.IOException: PDF startxref not found. at com.lowagie.text.pdf.PRTokeniser.getStartxref(Unknown Source) at com.lowagie.text.pdf.PdfReader.readXref(Unknown Source) at com.lowagie.text.pdf.PdfReader.readPdf(Unknown Source) at com.lowagie.text.pdf.PdfReader.init(Unknown Source) at Test.main(Test.java:197) and these are the last few lines when I print the output of the pdf: /CreationDate (D:20020506141920) /Producer (Acrobat Distiller 4.05 for Windows) /ModDate (D:20020506163216-04'00') endobj xref 0 3 00 65535 f 013590 0 n 013654 0 n trailer /Size 3 /ID[fd410d69fcd8f410ab0eb70c99931970fd410d69fcd8f410ab0eb70c99931970] startxref 173 %%EOF It looks to me as if this is the line its looking for but can't find for some reason.

[iText-questions] File does not begin with %PDF
Hey, has anyway encountered the specifics to the following error which happens with IE when streaming back a generated pdf file: File does not begin with %PDF. There is no problem with Netscape, Mozilla, or Opera, strictly IE on various versions of Windows. I am using iText to generate the PDF on the fly and stream it back over an SSL enabled connection. I have downloaded the file and verified that it is formatted correctly, and have also opened the same file directly in IE from my harddrive to ensure that IE does correctly recognize the file which it does. I have seen through several news groups that others have had the same problem, but no one has actually posted a workaround. I know that it is directly related to the web integration with Acrobat Reader, but disabling web integration is not an issue. Anyone encounter this?

I'll tell you what I think Bruno might say: Make two Cells, one left-aligned, the other right-aligned.

Re: **SPAM** [iText-questions] File does not begin with %PDF
I know this problem well (I spend 3 full days trying to track it down). My guess is that you are using IE 5.5. The problem is with the browser not iText and not the version of windows. There is a problem with IE 5.5 (works fine in IE 5 and IE 6) that it tries to download pdf's into its local cache and load them from there. At least in tomcat 4 (I haven't tried other app servers), servlet content gets marked no-cache to keep proxy servers from caching it. So this no-cache header tells IE not to cache the file, but then IE 5.5 goes ahead and tries to load it from the cache anyway. The File does not begin with %PDF is true because what IE just loaded was a file that did not exist (it loads it as zero bytes) so clearly it doesn't start with anything. The solution: upgrade IE 5.5 to the latest service pack or upgrade to IE 6. (or maybe try a different app server if you are using tomcat 4--the bug could be in the tomcat 4/ie 5.5 combination--though the fact that ms fixed this problem in a service pack points heavily to the problem being their's). --jim - Original Message - From: Fred Boulos [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, June 13, 2002 10:11 AM Subject: **SPAM** [iText-questions] File does not begin with %PDF Hey, has anyway encountered the specifics to the following error which happens with IE when streaming back a generated pdf file: File does not begin with %PDF.

Re: [iText-questions] PdfReader error
iText searches for the startxref in the last 1K of the file. See if the array has the size of the PDF. A common problem is to get the blob from the database as text and not as binary. Are you sure that if you get the PDF from the database and then save it to a file it still opens?
