I'm getting the following exception when the convert method in Prince is being invoked...

Prince.convert(xmlInput, pdfOutput);

Here, the input is actually HTML and hence I have used the property setHTML(true) to instruct the Prince to consider the input stream as HTML.

It runs perfectly in my local Windows machine, but the below error appears in the (Linux server)Distributed environment only. Though I could see no reason for this failure with the environment... I'm still not sure of the problem...

java.io.IOException: PDF header signature not found.
at com.lowagie.text.pdf.PRTokeniser.checkPdfHeader(Unknown Source)
at com.lowagie.text.pdf.PdfReader.readPdf(Unknown Source)

Has anyone come across this issue? How to overcome this...?. Thanks...

This exception is not coming from Prince, it is coming from whatever tool you are using to try to read the generated PDF file. Is convert() returning false? Can you call setLog() to specify a log file to see if Prince is producing any error or warning messages?

Mike,

As you said, I verified the IsConvert method - It does returns False. Moreover I added the setLog() file and I could see the following error;

Fri Nov 11 15:42:09 2011: Converting document...
Fri Nov 11 15:42:09 2011: warning: no glyphs for character U+0043, fallback to '?'
Fri Nov 11 15:42:09 2011: internal error: no available fonts
Fri Nov 11 15:42:09 2011: ---- end

We are using UTF-8 for HTML encoding, Does it have something to do with this error?
If so, What type of Encoding is supported for PRINCE in Linux ? Thanks in advance for your help...

The "no available fonts" error is the main problem: you need to install some fonts on your Linux server, such as the Microsoft Core Fonts (msttcorefonts) or DejaVu fonts, as described here.

Mike,
We installed the required fonts and its Working now!!! Thanks for your timely support...
