Adding a content transformer - NOT working

On Debian I have written a shell script(works perfectly when called on terminal),
that converts scanned PDF to PDF with computer text
and I want to include this transformation in Alfresco.
Since I have never tried adding a new content transformer, I started
with only adding a pdf to tiff transformer in alfresco(the first step
in my transformation from scanned PDF to PDF with text)

I did the following:

  - Added a tiff mimetype, to the mimetypes shown in transform content to image:
 
  <config evaluator="string-compare" condition="Action Wizards">
      <image-transformers>
    <transformer name="image/tiff"/>
      </image-transformers>
   </config>

  - Applied the rule on a space for the transformation of inbound content from pdf to tiff.

  - Added a transformer in the folder tomcat/shared/classes/alfresco/extension with the following code

I can do all this without alfresco complaining, but when I try to add a pdf file to the folder,
I get the following error( from alfresco.log file)

What did I do wrong ?
And do I have any other options to include a transformation with shell code in alfresco?
thanks for any answers.
