I have a WAR application that includes a JAR library. The JAR library contains the Batch Job and the Batch Artifacts (META-INF/batch-jobs/...). The WAR app includes this jar as a library and defines a JAX-RS Service that allows to clients to invoke the batch job calling the JobOperator Interface...
When i run this deployment, the JSR 352 implementation (JBeret) keeps complaining that the Job cannot be found anyware when the JobOperator Interface is called... However, if the Batch Job and the Batch Artifacts are included as classes of the WAR deployment, everything runs smoothly...
So, what is the problem?
After a "little" research, i found the answer (dispersed) in the following links:
Briefly, In order to put this kind of deployment to work, you have to modify the deployment that calls the Job Operator interface to invoke the requested Job (in my case, it was the WAR File)... These are the modifications:
Include an "empty" batch-jobs folder under the META-INF folder. (I guess the empty is optional, because i have to put a README file under that folder to prevent GIT from removing such folder)
Define a ServiceLoader (file) under META-INF/services folder. This ServiceLoader (file) must be called: org.jberet.spi.JobXmlResolver and should contain the following implementation as content: org.jberet.tools.MetaInfBatchJobsJobXmlResolver
That's all.
