Version 22

    The WildFly 10 Beta release is now available for download on wildfly.org.

     

     

    Java EE 7


    As with WildFly 8 and WildFly 9, WildFly 10 implements the Java EE 7 Full and Web Profile standards.



    Java 8+

     

    Java 7 support has been discontinued allowing for deeper integration with the Java 8 runtime. While Java 9 is still in development, this release runs on the current development snapshots.

     

     

    ActiveMQ Artemis

     

    Late last year, the HornetQ codebase was donated to the Apache ActiveMQ project, and the HornetQ community joined to build a next-generation messaging broker. This was materialized in the first major release of the ActiveMQ Artemis project. ActiveMQ Artemis includes many new features, and also retains protocol compatibility with the HornetQ broker. WildFly 10 Beta includes this new exciting project as its JMS broker, and due to the protocol compatility, it fully replaces the HornetQ project.

     

     

    Offline CLI Support for Domain Mode


    In addition to the offline CLI support for standalone mode, you can now launch a host-controller locally within the CLI. Using the embed-host-controller command you can edit the content of domain.xml and host.xml without launching additional processes or opening network sockets.



    HA Singleton Deployments

     

    WildFly 10 adds the ability to deploy a given application as a "singleton deployment". This is a new implementation of a feature that existed in AS 6.0 and earlier. When deployed to a group of clustered servers, a singleton deployment will only deploy on a single node at any given time. If the node on which the deployment is active stops or fails, the deployment will automatically start on another node. The policies for controlling HA singleton behavior are managed by a new "singleton" subsystem.  A deployment may either specify a specific singleton policy or use the default subsystem policy. A deployment identifies itself as singleton deployment via a /META-INF/singleton-deployment.xml deployment descriptor (the schema for which can be found here: https://github.com/wildfly/wildfly/blob/10.0.0.Beta1/clustering/singleton/extension/src/main/resources/schema/singleton-deployment-1.0.xsd), which is most easily applied to an existing deployment as a deployment overlay. Alternatively, the requisite singleton configuration can be embedded within an existing jboss-all.xml.

     

     

    Migration Operations for Discounted Subsystems

     

    To help users migrating from old subsystems such as jbossweb (AS 7.1), jacorb (WildFly 8), and hornetq (WildFly 9), we have introduced a set of management operations that can convert old configuration over to the new respective subsystem equivalent. Since these operations migrate the underlying management resource model, old CLI scripts or custom provisioning systems can also take advantage of these.

     

     

    JavaScript Support with Hot Reloading


    WildFly 10 includes the Undertow JS project, which allows you to write server side scripts that can pull in CDI beans and JPA Entity Beans. This can be quite useful for throwing together a quick view layer (perhaps using a templating language like Mustache, or a framework like Angular), or quickly developing a REST endpoint. You can edit the JS files live on the system, and they are dynamically reloaded, without having to redeploy your application.

    Capabilities and Requirements


    Subsystem developers now have the ability to negotiate interaction with other subsystems in a more pluggable way. This allows for subsystems to have dependencies that can be satisfied by more than one subsystem, which is particularly useful in providing multiple implementations of the same underlying capability. Additionally it leads to improved error reporting. Instead of a failure being reported at the service layer, which is how the WildFly runtime is mapped, it is instead reported at a higher level that is easier to connect to the server's configuration  As an example, a missing socket binding is now reported as a missing socket binding, as opposed to a list of services with an unsatisfied dependency. Expect to see overall error reporting in WildFly improve as subsystems begin to adopt this ability

    Hibernate 5

     

    Hibernate 5 includes several additional improvements, such as greatly improved bytecode enhancement, which is a useful performance optimization. Additionally a number of API improvements are provided, including use of generics in Hibernate Native, and an improved SPI for second level cache providers. Also included are new and improved schema update and validation tooling.

     

     

    Batch (JSR-352)

     

    Previously the batch subsystem was located under the path subsystem=batch. It has been moved to subsystem=batch-jberet with some changes to the subsystem model. WildFly 8 and 9 configuration files will still boot and work under under the subsystem=batch path.

     

    To highlight the changes in the management model. Two new resources were added in-memory-job-repository and jdbc-job-repository. You can have any number of these new resources defined, but the name must be unique across all *-job-repository resources. The job-repository-type attribute has been removed and replaced with a default-job-repository attribute. The value for this attribute is one of the defined job repositories.

     

    Finally since you can have multiple job repositories you can also have multiple thread pools. These can be used in a jboss-all.xml deployment descriptor.

     

    You can read more about batch in the WildFly documentation.
