Using HornetQ in the CityTech Summit World 2010 App

    Tuesday, June 15, 2010

    So some of the developers here at CITYTECH have been busy putting together an application that will run at this year’s Red Hat Summit/JBossWorld.  I’m sure you’ll hear more about it across the CT blogs (you may have already), but basically it will be a cross platform mobile app that will serve up Red Hat/JBoss trivia questions to conference participants who have downloaded the app and registered.  Users will then accumulate points by answering questions, and there will be a weighted raffle for great prizes at the end. In addition to all of the mobile goodness, the application will feature some cool JBoss projects on the back end including Infinispan, ModeShape and RESTEasy.  Oh, the back end will all run on JBossAS installed on AWS.

    Using Offsets and Sorting with Alfresco/jbpm Pooled Tasks

    Wednesday, January 21, 2009

    Awhile back co-worker Jeff Brown detailed how to extend Alfresco’s jBPM workflow implementation to limit the number of tasks pulled when retrieving ‘All Active Tasks’ (for some more background and implementation details click here).  Unfortunately, these changes don’t apply when retrieving ‘Pooled Tasks’, so more extension is necessary.  Real briefly, what happens when you ask Alfresco for Pooled Tasks and give it an Actor (user or group) is that it tries to figure all out of the groups that apply to this Actor (if its a user it figures what groups the user belongs to, and if its a group it figures out all parent groups).  Then the database is queried for all tasks belonging to these groups and a user ID, if applicable.  So, in a nutshell, it goes through some code the All Active Tasks does not.
