Error converting from PDF to DOC

[nlcom]

Hello, I am using Debian with TomCat to run Alfresco Community 2.1.0 build484 and OpenOffice 2.0.4

When I try to transform PDF files to DOC we get the following error:
Anyone know what this could be ?

Here is a log file from Alfresco itself:

Hi,

No transformation exists between mimetypes application/pdf and application/msword

None of the built-in transformation engines are able to accurately transform a document from PDF to Word.  You could try to build a complex transformer that does PDF->Html->Doc or some other combinations, but be prepared for humourous results.  Otherwise find a command line utility that does the job and register a tranformer for it.

This is also happening when going from DOC to PDF.
Also tried DOC to HTML and it also fails with the same error 😕

I've been searching on the forum and came across this: http://forums.alfresco.com/viewtopic.php?t=8467&highlight=transformation+exists

Also why is the rule present if it doesn't work properly?
Do I need to install something else to make it work? Could you be a bit more specific about this, what I need to do ?

[derek]

The rule is to convert to a particular format.  There are hundreds of possible input formats, so it is up to you to taylor the rule to suit the server's capabilities.

Are there any startup warning or error message related to Open Office?

Regards

Hi,

Try upgrading to the lastest version of Open Office if you are not already using that, and during installation, install into a directory that doesnt have spaces in the name eg c:\OpenOffice if you are running Windows. Then also check the files <Alfresco-Root>\tomcat\shared\classes\alfresco\extension\bootstrap\openoffice-startup-context.xml and <Alfresco_root>\alfresco.bat and make sure that the path to the Open office soffice program is correct. Restart Alfresco.
