Java: Press Release

OpenXava 5.0 Released

Rapid Development for Java

OpenXava is an 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.
This 5.0 release has a new look & feel, includes module navigation, user login/logout (so you do not need Liferay anymore), inline editable collections (just like a spreadsheet), a new editor to attach files to your entity, and many many more things.

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

New look & feel

Just have a look at the demo to see the new look & feel.

Module navigation

At last, your OpenXava applications will include menus to access the modules:


So, you do not need use Liferay for providing module navigation to your application, a simple Tomcat is enough. Anyways, you can still deploy your application on Liferay where these new menus are not shown.

User login

Now your application will ask your user to sign in:

So, you do not need to use Liferay to provide user login/logout. Anyways, If you deploy on Liferay this login/logout mechanism will not be used. Moreover, you can disable it if you wish, for testing or for public applications.

Editable collections

In OpenXava 5.0 you can have collections like this one:

Where the user can modify any property of any element in any moment, and where all collection elements are saved at once when the main entity is saved.
These collections are defined using @ElementCollection, a new annotation of JPA 2 specification. These are collections of embeddable object (not entities).
For defining an element collection just use @ElementCollection instead of @OneToMany: Download OpenXava 5.0

@ElementCollection
@ListProperties("product.number, product.description," +
    "product.unitPrice, quantity, " +
    "amount[invoice.sum, invoice.vat, invoice.total]")
private Collection<InvoiceDetail> details;

And define the class for the element collection as @Embeddable instead of @Entity:

@Embeddable
public class InvoiceDetail {

The generated user interface for this code will be:


You can see how these collections support calculated properties, references, totals, etc.

Editor to attach files

Until now to attach files to your entities you should create your own editor. That is no longer needed, now you can use the new FILE stereotype, thus:

@Stereotype("FILE")
@Column(length=32)
private String trailer;

To get this:

It can be configured to store the files in the database or the file system.

Others improvements

We have done a lot of improvements in other areas:

  • New renderer engine to layout the user interface.
  • Look and feel of date editor improved.
  • Several reports in one PDF with the new JasperConcatReportBaseAction.
  • @Collapsed annotation to initiate collections and references with the frame closed. Also allowed in XML components.

  • Objects class from org.openxava.util removed, you can use XObjects instead.
  • New is/setCollapsed() methods in View to close a frame of a reference or collection programmatically.
  • Added validateMinimum() and validateMaximum() to CollectionElementViewBaseAction.
  • New getPopupPDFPageCount() method in ModuleTestBase.
  • New methods setValueInCollection(), assertEditableInCollection() and assertEditableInCollection() in ModuleTestBase.
  • New method noFirstTokenWithoutFirstDelim() in Strings.
  • When @Digits is specified default scale is ignored even if fraction is not specified.

The Workspace-as-a-Service (WaaS) market will grow to $6.4B by 2018. In his session at 16th Cloud Expo, Seth Bostock, CEO of IndependenceIT, will begin by walking the audience through the evolution of Workspace as-a-Service, where it is now vs. where it going. To look beyond the desktop we must understand exactly what WaaS is, who the users are, and where it is going in the future. IT departments, ISVs and service providers must look to workflow and automation capabilities to adapt to growing demand and the rapidly changing workspace model.
The true value of the Internet of Things (IoT) lies not just in the data, but through the services that protect the data, perform the analysis and present findings in a usable way. With many IoT elements rooted in traditional IT components, Big Data and IoT isn’t just a play for enterprise. In fact, the IoT presents SMBs with the prospect of launching entirely new activities and exploring innovative areas. CompTIA research identifies several areas where IoT is expected to have the greatest impact.
Wearable devices have come of age. The primary applications of wearables so far have been "the Quantified Self" or the tracking of one's fitness and health status. We propose the evolution of wearables into social and emotional communication devices. Our BE(tm) sensor uses light to visualize the skin conductance response. Our sensors are very inexpensive and can be massively distributed to audiences or groups of any size, in order to gauge reactions to performances, video, or any kind of presentation.

Cloud data governance was previously an avoided function when cloud deployments were relatively small. With the rapid adoption in public cloud – both rogue and sanctioned, it’s not uncommon to find regulated data dumped into public cloud and unprotected. This is why enterprises and cloud providers alike need to embrace a cloud data governance function and map policies, processes and technology controls accordingly. In her session at 15th Cloud Expo, Evelyn de Souza, Data Privacy and Compliance Strategy Leader at Cisco Systems, will focus on how to set up a cloud data governance program and s...

PubNub on Monday has announced that it is partnering with IBM to bring its sophisticated real-time data streaming and messaging capabilities to Bluemix, IBM’s cloud development platform. “Today’s app and connected devices require an always-on connection, but building a secure, scalable solution from the ground up is time consuming, resource intensive, and error-prone,” said Todd Greene, CEO of PubNub. “PubNub enables web, mobile and IoT developers building apps on IBM Bluemix to quickly add scalable realtime functionality with minimal effort and cost.”
Sensor-enabled things are becoming more commonplace, precursors to a larger and more complex framework that most consider the ultimate promise of the IoT: things connecting, interacting, sharing, storing, and over time perhaps learning and predicting based on habits, behaviors, location, preferences, purchases and more.

In the consumer IoT, everything is new, and the IT world of bits and bytes holds sway. But industrial and commercial realms encompass operational technology (OT) that has been around for 25 or 50 years. This grittier, pre-IP, more hands-on world has much to gain from Industrial IoT (IIoT) applications and principles. But adding sensors and wireless connectivity won’t work in environments that demand unwavering reliability and performance. In his session at @ThingsExpo, Ron Sege, CEO of Echelon, will discuss how as enterprise IT embraces other IoT-related technology trends, enterprises with i...
When it comes to the Internet of Things, hooking up will get you only so far. If you want customers to commit, you need to go beyond simply connecting products. You need to use the devices themselves to transform how you engage with every customer and how you manage the entire product lifecycle.

The Internet of Things (IoT) is causing data centers to become radically decentralized and atomized within a new paradigm known as “fog computing.” To support IoT applications, such as connected cars and smart grids, data centers' core functions will be decentralized out to the network's edges and endpoints (aka “fogs”). As this trend takes hold, Big Data analytics platforms will focus on high-volume log analysis (aka “logs”) and rely heavily on cognitive-computing algorithms (aka “cogs”) to make sense of it all.
