Does anybody know how to change the log level to debug ?

i am trying to figure out the problem related to the "render" of document ("The preview could not be loaded from the server").

I am sorry for my "easy" question but alfresco is a huge world to learn ..

thanks

I had the same problem on OpenSuse 11.3 64 Bit.

The solution was to install some missing 64Bit C++ library. You can check the path of pdf2swf in alfresco-global.properties. Then execute this command in a shell and see if it works fine. I my case, it printed out the name of the missing library.

Hope this helps.

It's so simple,

1. Install swftools (in ubuntu: sudo apt-get install swftools)
2. locate pdf2swf (usually in /usr/sbin/pdf2swf)
3. open your /opt/alfresco-x.x.x/tomcat/shared/classes/alfresco-global.properties

edit your default setting to something like this:

ooo.enabled=true
swf.exe=/usr/sbin/pdf2swf

save and then restart the alfresco : alfresco.sh restart

It works for me

I discovered this also with a fresh install of alfresco-3.4.d.

My resolution was slightly different; following the above instructions I located the path to pdf2swf, and upon attempting to execute it was presented with the following error:
/opt/alfresco-3.4.d/common/bin/.pdf2swf.bin: error while loading shared libraries: /opt/alfresco-3.4.d/common/lib/libstdc++.so.5: file too short

libstdc++.so.5 files:
-rw-r–r– 1 root root 23 Nov 29 23:42 libstdc++.so.5
-rw-r–r– 1 root root 710608 Nov 29 23:42 libstdc++.so.5.0.3

investigation found the libstdc++.so.5 file contained the following:
# cat libstdc++.so.5
link libstdc++.so.5.0.3

So by removing the dud 'link', and creating a proper one:
rm -f libstdc++.so.5
ln -s libstdc++.so.5.0.3 libstdc++.so.5

Now running pdf2swf from the cli now gives me a list of parameters + options, and the flash preview works perfectly.

Hope this helps others.

Hi,

rm -f libstdc++.so.5
ln -s libstdc++.so.5.0.3 libstdc++.so.5

this was very helpful, thanks a lot!
