JBoss EAP 7 Beta is now released, many congratulations to Red Hat and particularly to the WildFly team!

There are plenty of improvements coming in this release as documented in Release Notes. One of the major themes is Java EE 7 compliance.

JBoss EAP 7 and Java EE 7

IBM and Oracle already provide commercially-supported Java EE 7-compliant Application Servers. And now Red Hat will be joining this party soon as well. Already WildFly has supported Java EE 7 for over two years, but commercial support is critical for open source to be adopted enterprise-wide. So this is good news!

You can learn all about different Java EE 7 APIs in the DZone Refcardz that I authored along with @alrubinger.

There are plenty of “hello world” Java EE 7 Samples that should all run with JBoss EAP. Hopefully, somebody will update the pom.xml and add a new profile.

Why NoSQL?

If you are building a traditional enterprise application then you might be fine using an RDBMS. There are plenty of advantages to using RDBMS, but using a NoSQL database instead has a few advantages:

There is no need to have a pre-defined schema and that makes them a schema-less database. The addition of new properties to existing objects is easy and does not require ALTER TABLE. The unstructured data gives flexibility to change the format of data any time without downtime or reduced service levels. Also there are no joins happening on the server because there is no structure and thus no relation between them.
Scalability, agility, and performance are more important than the entire set of functionality typically provided by an RDBMS. This set of databases provide eventual consistency and/or transactions restricted to single items, but more focus on CRUD.
NoSQL is designed to scale-out (horizontal) instead of scale-up (vertical). This is important knowing that databases, and everything else as well, is moving into the cloud. RDBMS can scale-out using sharding but requires complex management, not for the faint of heart. Queries requiring JOINs across shards is extremely inefficient.
RDBMS have impedance mismatch between the database structure and the domain classes. An Object Relational Mapping, such as one provided by Java Persistence API or Hibernate, is needed in such a case.
NoSQL databases are designed for less management and simpler data models lead to lower administration cost as well.

So, now you are all excited about NoSQL and want to learn more, right? Check out these links:

In short, there are four different types of NoSQL databases:

Document: Couchbase, Mongo, and others
Key/Value: Couchbase, Redis, and others
Graph: Neo4J, OrientDB, and others
Column: Cassandra and others

Java EE 7 provides a Java Persistence API that does not provide any support for NoSQL. So, how do you get started with NoSQL with JBoss EAP 7?

This blog will show how to query a Couchbase database using simple Java EE application deployed on JBoss EAP 7 Beta.

What is Couchbase?

Couchbase is an open-source, NoSQL, document database. It allows us to access, index, and query JSON documents while taking advantage of integrated distributed caching for high performance data access.

Developers can write applications to Couchbase using many different languages (Java, Go, .NET, Node, PHP, Python, C) and multiple SDKs. This blog will show how you can easily create a CRUD application using Java SDK for Couchbase.

Run JBoss EAP 7

There are two ways to start JBoss EAP 7.

Download and Run

./jboss-eap-7.0/bin/standalone.sh

Docker Run

In a containerized world, you just docker run to run your JBoss EAP. However, JBoss EAP image does not exist on Docker Hub and so the image needs to be explicitly built. You still need to explicitly download JBoss EAP and then use the following Dockerfile to build the image:

# Use latest jboss/base-jdk:8 image as the base
FROM jboss/base-jdk:8

# Set the JBOSS_VERSION env variable
ENV JBOSS_VERSION 7.0.0.Beta
ENV JBOSS_HOME /opt/jboss/jboss-eap-7.0/

COPY jboss-eap-$JBOSS_VERSION.zip $HOME

# Add the JBoss distribution to /opt, and make jboss the owner of the extracted zip content
# Make sure the distribution is available from a well-known place
RUN cd $HOME \
    && unzip jboss-eap-$JBOSS_VERSION.zip \
    && rm jboss-eap-$JBOSS_VERSION.zip

# Ensure signals are forwarded to the JVM process correctly for graceful shutdown
ENV LAUNCH_JBOSS_IN_BACKGROUND true

# Expose the ports we're interested in
EXPOSE 8080 9990

# Set the default command to run on boot
# This will boot JBoss EAP in the standalone mode and bind to all interface
CMD ["/opt/jboss/jboss-eap-7.0/bin/standalone.sh", "-b", "0.0.0.0", "-bmanagement", "0.0.0.0"]

The image is built as:

docker build -t arungupta/jboss-eap:7-beta .

And then you can run the JBoss EAP 7 container as:

docker run -it -p 8080:8080 arungupta/jboss-eap:7-beta

Notice how application and management ports are bound to all network interfaces. This will simplify to deploy the application to this JBoss EAP instance later.

Stop the server—we will show an easier way to start it later.

Start Application Server and Database

The Java EE application will provide an HTTP CRUD interface over JSON documents stored in Couchbase. The application itself will be deployed on JBoss EAP 7 Beta. So, it would require to start Couchbase and JBoss EAP.

Use the Docker Compose file from github.com/arun-gupta/docker-images/blob/master/jboss-eap7-nosql/docker-compose.yml to start Couchbase and JBoss EAP 7 container:

mycouchbase:
  container_name: "db"
  image: couchbase/server
  ports:
    - 8091:8091
    - 8092:8092 
    - 8093:8093 
    - 11210:11210
jboss:
  image: arungupta/jboss-eap:7-beta
  environment:
    - COUCHBASE_URI=db
  ports:
    - 8080:8080
    - 9990:9990

The application is started as:

docker-compose --x-networking up -d
Creating network "jbosseap7nosql" with driver "None"
Starting jbosseap7nosql_jboss_1
Creating db

The started containers can be seen as:

docker ps
CONTAINER ID        IMAGE                        COMMAND                  CREATED             STATUS              PORTS                                                                                               NAMES

cb76d4e38df3        arungupta/jboss-eap:7-beta   "/opt/jboss/jboss-eap"   10 seconds ago      Up 9 seconds        0.0.0.0:8080->8080/tcp, 0.0.0.0:9990->9990/tcp                                                      jbosseap7nosql_jboss_1

Configure Couchbase Server

Clone couchbase-javaee application. This Java EE application uses Couchbase Java SDK APIs to connect to the Couchbase server. The bootstrap code is:

CouchbaseCluster.create(System.getenv("COUCHBASE_URI"));

and is invoked from Database abstraction.

Couchbase Server can be configured using REST API. These REST APIs are defined in a Maven profile in pom.xml of this application. And so, they configure the Couchbase server as:

mvn install -Pcouchbase -Ddocker.host=$(docker-machine ip couchbase)

Deploy Java EE Application to JBoss

Java EE Application can easily be deployed to JBoss EAP 7 Beta using the WildFly Maven Plugin. This is also defined as a Maven profile in pom.xml as well.

Deploy the application as:
