Unable to load job xml in jar files inside WAR (and EAR) in EAP 7.0.x

Solution Unverified - Updated

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 7.0.x

Issue

META-INF/batch-jobs/batchInJar.xml in a batch jar file inside WAR is ignored and never loaded. This resulted in the following exception when executing a batch job in jar inside WAR.

javax.batch.operations.JobStartException: JBERET000601: Failed to get job xml file for job batchInJar.xml
 	at org.jberet.creation.ArchiveXmlLoader.getJobXml(ArchiveXmlLoader.java:129)
 	at org.jberet.creation.ArchiveXmlLoader.loadJobXml(ArchiveXmlLoader.java:91)
 	at org.jberet.operations.JobOperatorImpl.start(JobOperatorImpl.java:102)
 	at service.BatchService.start(BatchService.java:11)
	at controller.BatchTestController.batchInJarStart(BatchTestController.java:27)
        ...(snip)...

Here's an example directory structure of the war file and the jar file included in the war file:

[1] batch-jar-in-war.war
    |-- index.xhtml
    |-- META-INF
    |   `-- MANIFEST.MF
    `-- WEB-INF
        |-- classes
        |   |-- ...
        |   `-- META-INF
        |       `-- batch-jobs
        |           `-- batchInWar.xml <-- This job xml works
        |-- faces-config.xml
        |-- lib
        |   `-- simpleBatch-1.0.jar --- [2]
        `-- web.xml

[2] simpleBatch-1.0.jar
    |-- META-INF
    |   |-- batch-jobs
    |   |   `-- batchInJar.xml  <-- This job xml is unable to load
    |-- processor
    |   `-- ...
    |-- reader
    |   `-- ...
    |-- service
    |   `-- ...
    `-- writer
        `-- ...

Resolution

This issue is a bug reported in the following JIRAs. This has been fixed in EAP 7.0.6 or later.

You can workaround this issue by adding META-INF/services/org.jberet.spi.JobXmlResolver with the following content to your batch jar file:

org.jberet.tools.MetaInfBatchJobsJobXmlResolver
