OpenXava 4.8 Released: Open Source Framework for WebSphere development

OpenXava 4.8 has many new interesting features

OpenXava is an AJAX Java Framework for Rapid Development of Enterprise Web Applications. In OpenXava you only have to write the domain classes in plain Java to get a web application ready for production.

OpenXava 4.8 has many new interesting features such as:

  • Nested actions in a drop-down menu in the button bar, by means of subcontrollers.
  • Many new improvements in 'My reports'.
  • Improvements in list mode.

See changelog for the complete list of new features and fixes.
We recommend you to download it and upgrade your OpenXava applications. Look at the migration instructions.

Nested actions with subcontrollers

With a subcontroller you can grouping several actions and show them in a drop-down button. In your controllers.xml you can write:

<controllers>
    <controller name="Color">
        ...
        <subcontroller
                controller="MyProcesses" 
                image="processes.png"/>
    </controller>
</controllers>

This adds a new button called MyProcesses that opens a drop-down list.


The options in the drop-down list are from the MyProcesses controller.

Improvements in 'My reports'

These are the 'My reports' improvements:

  • The user can modify the column labels.
  • The columns shown use the labels instead of the property names.
  • Hidden columns, they can be used for filtering and ordering but are not shown in the report.
  • The default value for comparators is '=' or 'starts with'.
  • Combos for @DescriptionsList references.
  • 'Generate Excel' action available.
  • Summation for columns allowed.
  • Report file name is the report title.

Improvements in list mode

These are the list mode improvements:

  • Booleans in list and collections are rendered with a green check sign.
  • On choosing a combo in list the filtering is executed automatically (it can be deactivated with filterOnChange=false).
  • The user can use calendars to filter by dates in list and collections.
  • New setLabel() method in Tab to change the column labels programmatically.

And more

IoT & Smart Cities Stories
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-c...
Machine learning has taken residence at our cities' cores and now we can finally have "smart cities." Cities are a collection of buildings made to provide the structure and safety necessary for people to function, create and survive. Buildings are a pool of ever-changing performance data from large automated systems such as heating and cooling to the people that live and work within them. Through machine learning, buildings can optimize performance, reduce costs, and improve occupant comfort by ...
The explosion of new web/cloud/IoT-based applications and the data they generate are transforming our world right before our eyes. In this rush to adopt these new technologies, organizations are often ignoring fundamental questions concerning who owns the data and failing to ask for permission to conduct invasive surveillance of their customers. Organizations that are not transparent about how their systems gather data telemetry without offering shared data ownership risk product rejection, regu...

Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
Digital Transformation: Preparing Cloud & IoT Security for the Age of Artificial Intelligence. As automation and artificial intelligence (AI) power solution development and delivery, many businesses need to build backend cloud capabilities. Well-poised organizations, marketing smart devices with AI and BlockChain capabilities prepare to refine compliance and regulatory capabilities in 2018. Volumes of health, financial, technical and privacy data, along with tightening compliance requirements by...
Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
