if you are thinking OCR, then there is maybe not opensource but free on windows .

http://wiki.alfresco.com/wiki/Tiger_OCR_integration works great.

Vividata ( not open source but works ).

if not ocr, then can not help you , because I do not know eather.

Class missing: org.alfresco.repo.content.transform.RuntimeExecutableContentTransformer

put this class instead org.alfresco.repo.content.transform.RuntimeExecutableContentTransformer .

hope this helps.

Thanks for your reply, can you please tell me the steps, how to do this ?

check if alfresco repo .jar is missing

Re: Scanner open-source integration

savic_prvoslav — Tue, 25 May 2010 22:05:49 GMT

ps : maybe we have version difference ,
see instruction hire

http://wiki.alfresco.com/wiki/Content_Transformations

as you can see it uses different class : <bean id="transformer.worker.dwg2pdf" class="org.alfresco.repo.content.transform.RuntimeExecutableContentTransformerWorker"> … I guess this is solution to your problem . sorry for previous mislead .

Re: Scanner open-source integration

joe_l3 — Wed, 26 May 2010 17:28:58 GMT

Hi aman79,

Intelliant OCR-AlfrescoTM Bundle 1.1 was originally released for Alfresco 3.0. In the old version, Alfresco used a single class "org.alfresco.repo.content.transform.RuntimeExecutableContentTransformer" to perform content transformations by executable commands (such as intelliant ocr.exe). Now, from 3.2 up, Alfresco uses 2 classes:
1. "org.alfresco.repo.content.transform.ProxyContentTransformer" as a "proxy" to allows separation between the content transformer registry and the various third party subsystems performing the transformation
2. "org.alfresco.repo.content.transform.RuntimeExecutableContentTransformerWorker" as a configurable wrapper to execute any command line transformation that accepts an input and an output file on the command line ( ocr.exe –replace –language fr –pdf –output-file "${target}" "${source}" ).
For this reason, Spring fails to create the bean 'transformer.Ocr.Tiff2Pdf' on Alfresco 3.3. All that appears on the log you posted:

09:40:05,109 ERROR [org.springframework.web.context.ContextLoader] Context initialization failed
org.springframework.beans.factory.BeanCreationException: …….Initialization of bean failed; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [org.alfresco.repo.content.transform.RuntimeExecutableContentTransformer] for bean with name 'transformer.Ocr.Tiff2Pdf' defined in file [C:\Alfresco\tomcat\shared\classes\alfresco\extension\ocr-transformers-context.xml]; nested exception is java.lang.ClassNotFoundException: org.alfresco.repo.content.transform.RuntimeExecutableContentTransformer….

Now, you must change the bean declaration in ocr-transformers-context.xml file on all transformers. Here an example for TIFF to PDF transformer:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>
<beans>
<!– ************ –>
<!– TIFF to PDF  –>
<!– ************ –>
   <!– Define ProxyContentTransformer –>
   <bean id="transformer.Ocr.Tiff2Pdf"  class="org.alfresco.repo.content.transform.ProxyContentTransformer"  parent="baseContentTransformer">
       <property name="worker">
            <ref bean="transformer.worker.Ocr.Tiff2Pdf" />
       </property>
   </bean>
   <!– Define RuntimeExecutableContentTransformerWorker –>
   <bean id="transformer.worker.Ocr.Tiff2Pdf" class="org.alfresco.repo.content.transform.RuntimeExecutableContentTransformerWorker" >
      <property name="mimetypeService">
         <ref bean="mimetypeService" />
      </property>
     <property name="explicitTransformations">
         <list>            
            <bean class="org.alfresco.repo.content.transform.ExplictTransformationDetails" >
               <property name="sourceMimetype"><value>image/tiff</value></property>
               <property name="targetMimetype"><value>application/pdf</value></property>
            </bean>
         </list>
      </property>
      <property name="checkCommand">
         <bean class="org.alfresco.util.exec.RuntimeExec">
            <property name="commandMap">
               <map>
                  <entry key=".*">
                     <value>ocr.exe –about</value>
                  </entry>
               </map>
            </property>
            <property name="errorCodes">
               <value>1,2</value>
            </property>
         </bean>
      </property>      
      <property name="transformCommand">
         <bean class="org.alfresco.util.exec.RuntimeExec">
            <property name="commandMap">
               <map>
                  <entry key="Windows.*">
                     <value>
                        ocr.exe –replace –language fr –pdf –output-file "${target}" "${source}"
                     </value>
                  </entry>
               </map>
            </property>
            <property name="errorCodes">
               <value>1,2</value>
            </property>
         </bean>
      </property>
      
   </bean>
……. and so on…..‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

GOOD luck
