DeclarativeWebScript not working

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

I have written a REST-signin call based on the Alfresco 2.1dev REST-login but when I call it from a browser then I get an exception which says the following:

freemarker.core.InvalidReferenceException: Expression ticket is undefined on line 2, column 11 in com/wannakey/user_signin.get.xml.ftl.

After some hardwork I found out that the setAuthenticationService in the Signin-class is called when Alfresco starts, but the executeImpl is never triggered. Not even when I GET the REST-call.

Alfresco's REST-login works, mine doesn't. What did I miss?


I use the following url:

http://localhost:8080/alfresco/service/user/signin?email=admin&password=admin

Below are the files that are used and they are in an AMP.

I suspect your Spring bean has not been hooked into your Web Script.

If you switch on:

log4j.logger.org.alfresco.web.scripts=debug‍

in

log4j.properties‍

and re-start the server (or 'refresh web scripts' from /alfresco/service/), all registered web scripts are logged including their Spring bean

e.g.

Found Web Script org/alfresco/repository/loginticket.delete (desc: org/alfresco/repository/loginticket.delete.desc.xml, impl: webscript.org.alfresco.repository.loginticket.delete, auth: user, trx: required, format style: any, default format: xml)

If you have:

impl: webscript_default

then your bean is not hooked up.  You need to adjust the id of the Spring bean.
