For example, I need an evaluator that I could use to show an action in Share. If the current user is the author of the document, I will show the action.
The structure of the project is presented below ( alf221-action-share):

tkbbank-exclude-participant-16.png
In the class, UsersCompareEvaluatorI'm just trying to determine the current user:
package com.tkbbank.alfresco.alf221.evaluators;
import org.alfresco.web.ui.common.component.evaluator.BaseEvaluator;
import org.springframework.extensions.surf.RequestContext;
import org.springframework.extensions.surf.support.ThreadLocalRequestContext;
import org.springframework.extensions.webscripts.connector.User;
public class UsersCompareEvaluator extends BaseEvaluator {
@Override
public boolean evaluate() {
RequestContext requestContext = ThreadLocalRequestContext.getRequestContext();
User user = requestContext.getUser();
System.out.println("CURRENT USER IS ... " + user.getName());
return true;
}
}
My alf221-action-share-slingshot-application-context.xml:
<?xml version='1.0' encoding='UTF-8'?>

The yar file that I posted on the following path: /opt/tomcat7/webapps/share/WEB-INF/lib
Everything works fine except for my custom evaluator. Share does not work in this configuration ... In the logs, I see the following:
[aleksey@alfresco01 tomcat7]$ sudo vi share.log

If in the evaluator I implement the interface ActionEvaliatorand try to identify the current user as follows:
public class UsersCompareEvaluator implements ActionEvaluator {
private Map<Object, Object> registeredBeans =
Context.getProcessEngineConfiguration().getBeans();
private ServiceRegistry registry =
(ServiceRegistry)registeredBeans.get(ActivitiConstants.SERVICE_REGISTRY_BEAN_KEY);
private AuthenticationService authenticationService =
registry.getAuthenticationService();
@Override
public boolean evaluate(Node node) {
System.out.println("CURRENT USER IS ... " +
authenticationService.getCurrentUserName());
return true;
}
@Override
public boolean evaluate(Object object) {
if(object instanceof Node) {
return evaluate((Node)object);
}
return false;
}
}
