openKM File Preview

[maverick757]

Hello everyone

I have a problem with my openKM configuration. I am running openKM on a Centos 6.3 x86_64 machine. I want to use preview for the file types .doc(x), xls(x), ppt(x), txt and pdf. I installed OpenOffice 3.4.1 from the RPM which wasn't to easy since CentOS decided to remove OpenOffice from the repo and add LibreOffice instead. I also installed pdf2swf and added the following to the openKM Config (in the adminstration Panel):

Code: Select all

system.swftools.pdf2swf /usr/bin/pdf2swf
system.openoffice.path /opt/openoffice3.org

File preview isn't working yet. Befoce I installed OpenOffice and added the pdf2swf file path, there was an error report when I clicked on Preview. Now there is only an Popup saying:

Code: Select all

"The system has generated an error - Conversion". Thats everything.

Could you please help me to get the file preview running? I don't really care wether OpenOffice or LibreOffice is used for file conversion, I just want it to work.

Kind regards

I'm using LibreOffice instead of OpenOffice.org, without any shortcommings. You do not need to install pdf2swf manually, it's already inside bin-folder in your OpenKM installation; to correctly call pdf2swf you have to add some commandline parameters, have a look inside the wiki!

To test OpenOffice you can upload a .odt file and try downloading it as pdf, there's only OpenOffice involved. If this works, then pdf2swf is at fault.

Thanks for the reply. Do I have to do anything besides telling openKM where it finds OpenOffice? I read something about a start script running OO in headless mode.

I think I will set up the server new in a few weeks (it was just for testing atm). I think I'll use LibreOffice, too then, because it's a lot easier to install using yum.
How did you go on ahead after the installation of openKM (Installation of LibreOffice and configuration in openKM?)

Kind Regards

I installed OpenKM on Ubuntu 12.04. I had LibreOffice installed through apt-get install, then i entered the path to soffice.bin in OpenKM, and that's it. I did not configure any special startup-scripts, afaik OpenKM will start OpenOffice / LibreOffice automaticly. I think you also need to install java for OpenOffice to run properly, at least i did so anyway.

[maverick757]

Okay, I'll give that a try.
By the way: I tried to download a .odt as .pdf, that did not work. Astonishingly downloading a .docx file as .pdf worked (Not as well as aspected, font style and a few other things were a bit messy).
I don't really want to reinstall the server now because I am just testing openKM and playing around.
Seems like OpenOffice is working or what do you think?
Where exactly in the wiki can I find the part about the pdf2swf configuraion?

Kind regards

Nope, there's something wrong with OpenOffice! It should be able to convert .odt to .pdf - if it is not, you might miss some essential part of OpenOffice. Did you install java jdk?

[maverick757]

Yes, right after I installed OpenOffice. How can I check whether OpenOffice is installed properly?

[macjaeger]

Sorry, can't help you there - OpenOffice always worked for me out of the box. But since you can convert some files but not others, it seems OpenOffice is only "a little broken". Maybe un- and re-installing would help (at least that's the windows' way to do it... *g*).

Installation for CentOs is not as easy as Ubuntu , sorry for my english !!
CentOs 5 or 6 x64 are my favorite distros but it's not very easy to install OpenKM on it. The best is running with VirtualBox and take a snapshot at each step. I did a lot of tests and here is the recipe :

So you need to install your CentOs in minimal without Gnome destop.

I test it with openkm-6.0.1-linux-x64-installer I have some problem with 6.2.4 may be an error I will wait next week. Don't add rpm forge , or disabled them BEFORE install and configure Open KM. Don't start OpenKM.

You need to install manually Open Office I give you the info for French version 3.4.1:

Code: Select all

source :  http://www.if-not-true-then-false.com/2010/install-openoffice-org-on-fedora-centos-red-hat-rhel/ 

First we remove some old package if they exist

Code: Select all

yum remove openoffice.org* libreoffice.org*
wget Apache_OpenOffice_incubating_3.4.1_Linux_x86_install-rpm_fr.tar.gz
tar -zxvf Apache_OpenOffice_incubating_3.4.1_Linux_x86_install-rpm_fr.tar.gz
cd fr
rpm -Uvh RPMS/*.rpm

We need to exclude upgrade for now

Code: Select all

nano -w /etc/yum.conf

## Add exclude row
exclude=openoffice.org-ure* libreoffice-ure*

Code: Select all

cd 
updatedb
locate soffice.bin
/opt/openoffice.org3/program/soffice.bin
so you need to put /opt/openoffice.org3 to the setting 
system.openoffice.path	String 	/opt/openoffice.org3 

For sftools , you can take the one inside opt/instalaltion path/tomcat/bin. Or you can compile it and add the librairies:

Code: Select all

sources : http://wiki.openkm.com/index.php/Third-party_software_integration:_SWFTools

http://www.myfotoblast.com/blog/?p=153

Code: Select all

yum install tcl tcl-devel libpng-devel libjpeg-devel libpaper-devel giflib giflib-devel ghostscript-devel bzip2-devel freetype-devel libtiff-devel zlib-devel gcc gcc-c++ make autoconf libtool automake
wget http://www.swftools.org/swftools-0.9.2.tar.gz
tar -xzvf swftools-0.9.2.tar.gz
mv swftools-0.9.2 swftools
cd swftools 
wget ftp://ftp.foolabs.com/pub/xpdf/xpdf-3.03.tar.gz
cd lib/pdf
tar –xzvf xpdf-3.03.tar.gz
cd ..
cd ..
./configure -prefix=/usr
make 
cd swfs

We need to edit Makefile and remove two lines with rm -o (CTRL+K on each line + CTRL+WX to save and exit)

Code: Select all

nano Makefile
rm -f $(pkgdatadir)/swfs/default_viewer.swf -o -L $(pkgdatadir)/swfs/default_viewer.swf
rm -f $(pkgdatadir)/swfs/default_loader.swf -o -L $(pkgdatadir)/swfs/default_loader.swf

cd ../
updatedb 
locate pdf2swf
/usr/bin/pdf2swf

for setting
system.swftools.pdf2swf you need to put :

Code: Select all

/usr/local/bin/pdf2swf –T 9 -f -t -G -s storeallcharacters ${fileIn} -o ${fileOut} 

for ImageMagick just:

Code: Select all

yum install ImageMagick*
which convert

for setting system.imagemagick.convert you need to put

Code: Select all

/usr/bin/convert 

So start OpenKM and try to upload an jpeg, and PDF file, also .doc (not docx or save them in word 97 format) and .odt file.
It should work

Give us feedback to help users and OpenKM's team

The real problem is on some linux distribution is difficult install some packages. For example for backup you can use rdiff-backup that's on official ubuntu or debian repos but on redhat / centos can be more difficult than make yum install rdiff-backup ( that's the different, if you have good control of redhat / centos distribution there's no major problem ).

For CentOS minimal instal 64 bit, after installing LibreOffice you need to add headless code

Code: Select all

yum install libreoffice-headless.x86_64

This solved my preview problem.
