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.
