OpenXava 4.9 Released

Open Source Framework for Rapid Development of WebSphere Applications

OpenXava is an Open Source Framework for Rapid Development of WebSphere Applications.

In OpenXava you only have to write the domain classes in plain Java to get a web application ready to be deployed into WebSphere Application Server or WebSphere Portal.

OpenXava 4.9 has many new interesting features such as:

  • We have improved the list with better behavior, new filter options and some style improvements.
  • PDF reports now are better adjusted, so most automatic reports are ready to be used.
  • 'My reports' has more options and it's easier to use. Now you can use your OpenXava application as a reporting tool.
  • Many other improvements and bug fixes.

We recommend you to download it and upgrade your OpenXava applications. Look at the migration instructions.

List improvements

These are the improvement for list and collections:

  • Combos and textfields in list filtering adapt their widths to the column and they are always completely visible.
  • 'in group' and 'not in group' (the 'in' of SQL) allowed to filter in list, collections and 'My reports'.
  • Link to hide filter is in the filter row itself.
  • Links to show and hide the filter are only visible in customization mode. Thus we have a less cluttered user interface.
  • New icons for customizing list and collections.
  • Paging in list and collections allows 12 rows per page. Useful if you have a row per month.

Now list mode of OpenXava is still better.

Improvements in automatic PDF reports

These are the automatic PDF reports improvements:

  • Algorithm to adjust columns optimized: right column is better adjusted and columns that not fit are dropped.
  • Width of columns is calculated from the real content, not from declaration.
  • Long labels can use several lines if needed.
  • Reports with no data show a page with an informative message instead of an empty report.
  • Reports use qualified labels for column header, just as list mode.
  • Detail line height optimized.

In this way, more automatic reports are ready to be used, therefore the programmers have to create less reports by hand.

Improvements in 'My reports'

These are the 'My reports' improvements:

  • The combo for adding columns only shows until second level properties by default.
  • Labels instead of internal names in combo for adding new columns.
  • Initial condition and ordering are populated from the current list.
  • Duplicate columns allowed to filter by range or complex conditions, though only one is shown in the report.
  • Dialog title of column editing improved.
  • Refactoring of 'My reports' code (CustomReport renamed to MyReport) that produces the loss of current stored user reports.


Thanks to these improvements in 'My reports' and PDF generation your users can use your OpenXava application as a tool for creating their own reports.

Others improvements

We have done a lot of improvements in other areas:

  • @AssertTrue message can be customized, even values of properties of the current entity can be used.
  • When a ConstraintViolationException is thrown the message to the user is obtained from the constraint definition.
  • @Size validation annotations produces a more significative message.
  • Support for multivalue editors with checkboxes.
  • It's possible to exclude the HTML head code when calling a module using htmlHead=false as argument.
  • Order for properties when no @View is defined is consistent for all Java vendors.
  • Subcontrollers are not shown when they have no action.
  • Style of subcontrollers improved.
  • Subcontrollers behavior improved: now they are closed on clicking again on the button or outside the popup menu.
  • Code for buttonBar.jsp and subButton.jsp downgraded to Java 1.4.
  • New TypicalNewOnInit controller that starts the module in detail mode ready to create a new entity.
  • New methods addDays(), lastOfYear(), lastOfMonth() and firstOfMonth() added to Dates.

Bug fixes

Though this is not a maintenance version we have done some fixes:

  • Fix: Methods setYear(), setMonth() and setDay() of Dates do not work.
  • Fix: Wrong OpenXava version number when using some third party libraries.
  • Fix: Filtering in list by Timestamp or DATETIME does not allows to specify the time part.
  • Fix: Totals in automatic PDF reports use two lines when the number is too large.
  • Fix: Little vertical white bar in subcontroller button.

As enterprises work to take advantage of Big Data technologies, they frequently become distracted by product-level decisions. In most new Big Data builds this approach is completely counter-productive: it presupposes tools that may not be a fit for development teams, forces IT to take on the burden of evaluating and maintaining unfamiliar technology, and represents a major up-front expense. In his session at @BigDataExpo at @ThingsExpo, Andrew Warfield, CTO and Co-Founder of Coho Data, will dis...

Eighty percent of a data scientist’s time is spent gathering and cleaning up data, and 80% of all data is unstructured and almost never analyzed. Cognitive computing, in combination with Big Data, is changing the equation by creating data reservoirs and using natural language processing to enable analysis of unstructured data sources. This is impacting every aspect of the analytics profession from how data is mined (and by whom) to how it is delivered. This is not some futuristic vision: it's ha...
WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.

Participants received the download information, scripts, and complete end-t...
For manufacturers, the Internet of Things (IoT) represents a jumping-off point for innovation, jobs, and revenue creation. But to adequately seize the opportunity, manufacturers must design devices that are interconnected, can continually sense their environment and process huge amounts of data. As a first step, manufacturers must embrace a new product development ecosystem in order to support these products.
Manufacturing connected IoT versions of traditional products requires more than multiple deep technology skills. It also requires a shift in mindset, to realize that connected, sensor-enabled “things” act more like services than what we usually think of as products. In his session at @ThingsExpo, David Friedman, CEO and co-founder of Ayla Networks, discussed how when sensors start generating detailed real-world data about products and how they’re being used, smart manufacturers can use the dat...
When it comes to IoT in the enterprise, namely the commercial building and hospitality markets, a benefit not getting the attention it deserves is energy efficiency, and IoT’s direct impact on a cleaner, greener environment when installed in smart buildings. Until now clean technology was offered piecemeal and led with point solutions that require significant systems integration to orchestrate and deploy. There didn't exist a 'top down' approach that can manage and monitor the way a Smart Buildi...
