Running a rule on a schedule?

drakee — Mon, 11 May 2009 20:32:45 GMT

I am new to using Alfresco, but I have searched unsuccessfully for documentation on how to do the following: I would like to create a simple rule that Publishes documents at a specific time interval (e.g. every week on Sunday at midnight). So, for example, this rule would move any documents in the '

OK, I think I figured out how this is supposed to work. In ${ALFRESCO_HOME}/tomcat/shared/classes/alfresco/extension/scheduled-actions-services-context.xml, I have:

On startup, this should initiate a schedule for moving a test image from the company home into the Published directory, every 5 minutes. However when starting Alfresco I get the error:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'templateActionModelFactory' is defined

Is this a known issue? I found one reference on the Internet:

But I didn't get any clues from that post. Thanks!

I figured out what was missing. In the scheduled-actions-services-context.xml file, I needed to include the following:


    <bean id="templateActionModelFactory" class="org.alfresco.repo.action.scheduled.FreeMarkerWithLuceneExtensionsModelFactory">
        <property name="serviceRegistry">
            <ref bean="ServiceRegistry"/>
        </property>
    </bean>
‍‍‍‍‍‍‍

After fixing that, I was finally able to get the scheduled action to work - but only after fixing a few other issues:

I had to comment out the "deep-copy" entry in the parameterTemplates map in scheduled-actions-services-context.xml

In CronScheduledQueryBasedTemplateActionDefinition.java:229 I had to print out the variable templateService and the result of getTemplateActionModelFactory() to avoid a NullPointerException.

In SimpleTemplateActionDefinition.java:202 I had to print out the variable dictionaryService and the variable paramName to avoid a NullPointerException

The last two fixes required downloading the Alfresco source from svn (version 3.2), altering the source code, and running ant to compile everything. I took the newly compiled classes and substituted them for the originals in ${ALFRESCO_HOME}/tomcat/webapps/alfresco/WEB-INF/lib/alfresco-repository.jar.

Hope this helps someone!
