Project connectorZ--Lean JCA 1.6 Connector Implementations
connectorZ project is an example connector implementation under Apache 2.0 license.
The initial project (work-manager) implementation uses JCA WorkManager to execute Runnable
implementations asynchronously:
@Stateless
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public class ThreadsResource {
@Resource(name="jca/workmanager")
WorkExecutorFactory executorFactory;
public String threads(){
try(WorkExecutor executor = executorFactory.newExecutor();){
Runnable runnable = new Runnable(){
@Override
public void run() {
//some work to do
}
};
executor.execute(runnable);
}
The main benefit over the EJB 3.1 @Asynchronous
annotation is better management and monitoring. JCA's connection pooling is configurable by application server, so throttling and monitoring comes for free.
[The connectorZ project was initiated by factoring out examples from the book "Real World Java EE Patterns--Rethinking Best Practices" book (Second Iteration), page 303 in, chapter "Generic (File) JCA"]
See you at Java EE Workhops at MUC Airport (October 22nd-24th)!
Thanks for sharing!
Can you give us some bootstarp for inbound jca with MDB?

Hi Adam!
Thanks for sharing this great jca 1.6 example on github. In the other hand there is no ra.xml in the compiled-bundled (mvn clean install) work-manager.rar file. Is it a bug or also a new jca 1.6 feature?
Thanks,
;-D
