JAX-RS & Arjuna Transactions

This example uses a JAX-RS resource and AtomicAction & friends.

Note, these are not Java EE compliant APIs and classes we're going to use. But that's the point!

Project pom.xml

The project adds a <plugin> to configure wildfly-swarm-plugin to create the runnable .jar.

<plugin>
  <groupId>org.wildfly.swarm</groupId>
  <artifactId>wildfly-swarm-plugin</artifactId>
  <version>${version.wildfly-swarm}</version>
  <executions>
    <execution>
      <phase>package</phase>
      <goals>
        <goal>create</goal>
      </goals>
    </execution>
  </executions>
</plugin>

To define the needed parts of WildFly Swarm, a dependency is added

<dependency>
    <groupId>org.wildfly.swarm</groupId>
    <artifactId>jaxrs</artifactId>
    <version>${version.wildfly-swarm}</version>
</dependency>
<dependency>
    <groupId>org.wildfly.swarm</groupId>
    <artifactId>transactions</artifactId>
    <version>${version.wildfly-swarm}</version>
</dependency>
<dependency>
    <groupId>org.wildfly.swarm</groupId>
    <artifactId>msc</artifactId>
    <version>${version.wildfly-swarm}</version>
</dependency>

Build

mvn package

Run

java -jar ./target/example-arjuna-shrinkwrap-swarm.jar

Use

First try ...

http://localhost:8080/atomicaction

In the browser you should see something like ...

Begin BasicAction: 0:ffffac1c8001:2fb05ec4:567ed3a5:b status: ActionStatus.RUNNING
Committed BasicAction: 0:ffffac1c8001:2fb05ec4:567ed3a5:b status: ActionStatus.COMMITTED

Then try ...

http://localhost:8080/begincommit

Should result in ...

Transaction begun ok and committed ok

Next ...

http://localhost:8080/beginrollback

Should give you the following in the browser ...

Transaction begun ok and committed ok

Now try ...

http://localhost:8080/beginrollback

You should get something like the following in your browser ...

Nested transaction  BasicAction: 0:ffffac1c8001:-315e47ea:567ed60e:19 status: ActionStatus.RUNNING started!
