RuntimeExecutableContentTransformer missing?

[oneporter]

Hi, I'm trying to set up a content transformation, and before really getting started I decided to pull one straight off of the wiki to test it out.  I created the file custom-context.xml and put it in <classpath>/alfresco/extension and filled it with:

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>

This comes straight from http://wiki.alfresco.com/wiki/Content_Transformations#RuntimeExecutableContentTransformer.

Starting Alfresco tells me that the class isn't found:

Did I set something up wrong or is the class just missing?  I'm using Labs 3.2preview.  Is there another way to use an external program for transformations?  Thanks a lot.

[oneporter]

I just downgraded to 3.0 stable, and it works fine.  It seems that the class is missing from the svn and 3.2pre

[mwildam]

I have a similar problem in the attempt to replace pdfbox with pdftotext - I was not able to get it to work so far using the pdftotext. I get this error with seems to be similar to yours - I am using 3.2 release:

I don't know

[mwildam]

I created a new issue as it seems that nobody has reported that to JIRA yet:
https://issues.alfresco.com/jira/browse/ALFCOM-3288

[cmgray]

I think the last item in this wiki page: http://wiki.alfresco.com/wiki/Upgrading_to_Alfresco_Community_Edition_3.2 explains what changes need to be made to any RuntimeExecutableContentTransformer declarations.

I've done that, however, and I'm getting errors

[cmgray]

Figured it out.  You need to add a mimetypeService property to the declaration

<property name="mimetypeService">
         <ref bean="mimetypeService" />
      </property>
‍‍‍‍

you can check the delivered swf-transform-context.xml for an example.

Hi
i have the same problem,in v3.0 i can transform my transformation but in v3.2 i can't set RuntimeExecutableContentTransformer to work.
Here is my xml:
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>
        <bean id="transformer.linklistxml" class="org.alfresco.repo.content.transform.ProxyContentTransformer"
              parent="baseContentTransformer">
                <property name="worker">
                        <ref bean="transformer.worker.linklistxml"/>
                </property>
       </bean>

These bean should make transformations,what is the right syntax?

<bean id="transformer.worker.linklistxml" class="org.alfresco.repo.content.transform.RuntimeExecutableContentTransformerWorker">
<entry key="Linux">
<value>/opt/Alfresco/Alfresco/bin/linklistxml ${source} ${target} >/dev/null </value>
</entry>
</bean>

</beans>

Some ideas.
Tnx

If you look at https://issues.alfresco.com/jira/browse/ETHREEOH-2704 - this is still an open bug. However, your pre-poster seemed to be able finding a workaround - I didn't try that.
