Document Previews Not Working

[anuvatec]

I get the "This document can't be previewed" error message when viewing a document on Alfresco Share (even with .TXT files). I checked the log file and it says:

13:49:03,797 ERROR [org.alfresco.repo.content.transform.RuntimeExecutableContentTransformerWorker] Failed to start a runtime executable content transformer:

The weird thing is I configure ImageMagick, convertd, pdf2swf, etc. in /opt/Alfresco/tomcat/webapps/alfresco/WEB-INF/classes/alfresco/repository.properties but the paths to those programs in the errors log are different.

How do I fix this issue? Am I configuring the wrong config file?

Yes you are configuring the wrong file.   You should never touch any of the the files within the WEB-INF folder.

First of all, never modify the .properties files within the WEB-INF folder directly - they'll get overwritten next time you upgrade or Tomcat re-deploys the war file.

As of v3.2, all customisation is via the alfresco-global.properties file. Please see this wiki article for more information.

Thanks,
Mike

I am running alfresco on centos 5. I have check the path for ImageMagick, convertd, pdf2swf in global properties and they are all correct. Yet the document preview is not working. All the pre-requisite i.e latest flash player, are fulfilled by the client system for running alfresco. Would really appreciate if anyone can reply soon.
