Java + PDFBox not working on linux server

Question

I use the library PDFBox(2.0.0) to convert pdf to png in a web app. The librairy works when I'm working locally on Mac OSX 10.10 but not when I deploy my web app on remote server "Ubunto 14.04"

docPDF  = PDDocument.load(new File(pathFPdf));
PDFRenderer pdfRenderer = new PDFRenderer(docPDF);
docPDF.getNumberOfPages();
BufferedImage bim = pdfRenderer.renderImageWithDPI(0, 300, ImageType.RGB);                                                  
ImageIOUtil.writeImage(bim, pngPreviewPath, 300);

Any help is appreciated.

What is the value of `pathFPdf`? Is there an error or exception? — Ken Brittain, Apr 27 '16 at 11:13
I tested the file (new File(pathFPdf)) exists, no error. Thanks — Camille Sochon, Apr 27 '16 at 11:57

I would give `-Djava.awt.headless=true` a try: http://askubuntu.com/questions/34480/exception-on-desktopsic-sun-awt-x11graphicsenvironment — Ken Brittain, Apr 27 '16 at 15:46
But PDFRenderer does use awt, so I wonder if this will work. Btw you're not checking the result of ImageIOUtil.writeImage. — Tilman Hausherr, Apr 27 '16 at 16:06
Thanks. I changed -Djava.awt.headless=true... I have new exception : java.awt.AWTError: Can't connect to X11 window server using ':1.0' as the value of the DISPLAY variable — Camille Sochon, Apr 28 '16 at 08:51

problem is solved

I use this parameter in tomcat startup bash : export DISPLAY=:0 -Djava.awt.headless=true

Java Can't connect to X11 window server using 'localhost:10.0' as the value of the DISPLAY variable

Thanks!!
