OpenKM 1.5.9 document any type preview doesn't work

[melal]

I'm configuring at the moment OpenKM 1.5.9 on Fedora 16. Everything is OK, OpenKM just a perfect system, but only one issue can't be solved by me. When I'm trying click "Preview" tab for documents of the following types, for example: pdf, png, jpg etc. - I see only "There was a problem with the conversion generation. Please, contact your OpenKM administrator." Of course, there is a problem with LibreOffice, but it's not important fro me now as soon there is a problem at the level of DocConverter initially. Obviosly there exists a bug for LibreOffice at jodconverter but this quietsion will be for another topic, as now I need help for graphics and PDF files only.

My settings:
system.ghostscript.ps2pdf String /usr/bin/ps2pdf
system.imagemagick.convert String /usr/bin/convert
system.ocr String /usr/bin/tesseract
system.openoffice.path String /usr/lib/libreoffice
system.openoffice.port Integer 2002
system.openoffice.tasks Integer 200
system.previewer String zviewer
system.swftools.pdf2swf String /usr/bin/pdf2swf

Installed software:
swftools-0.9.1-5.fc16.i686
ImageMagick-6.7.0.10-4.fc16.i686

Trying acces a graphics file I see in my server.log:

Code: Select all

OK, the problem is solved partially. Just have changed setting for pdf2swf inside admin panel from:

Code: Select all

system.swftools.pdf2swf	String	 /usr/bin/pdf2swf

to

Code: Select all

system.swftools.pdf2swf	String	 /usr/bin/pdf2swf ${fileIn} ${fileOut}

and therefore I can preview PDF files now. But still have problem with another graphics files: jpg, png, etc., server.log gives the following error:

Problem is solved. I have stopped jboss server, purged cache directory manually and started jboss again.

Topic is closed.

Hi
I have the same problem with openkm 6.3.2. Can you say me how can i restart JBOSS?

Thanks in advance!

This kind of error happens when you have complex documents with a lot of layers, take a look here https://docs.openkm.com/kcenter/view/ok ... leshooting

Hi!
Thanks for the answer but have you an idea how I can start Jboss server and purge the caches?
Thanks in advance!

Why are you still running this old OpenKM version 1.5.9 it's very very old, that is totally unsupported. When you are trying to preview a document should be some error, take a look at server.log file and share it with us ( please only the section with log error ).
