JBeret is an implementation of Jakarta Batch. It is also included in WildFly, the new and improved JBoss Application Server to provide portable batch processing support in Jakarta EE environment.
To build and run default set of tests:
mvn install
Some tests require additional steps and thus are not included in the default run. For instance, MongoDB-related tests need to start MongoDB first. To build and run all tests:
# start MongoDB database
mongod
# build JBeret, activate allTests maven profile to run all tests
mvn install -DallTests
Some tests involves very large data set (e.g., over 1 million rows of CSV or Excel data), and may cause memory errors in some machines:
OutOfMemoryError: unable to create new native thread
Increase ulimit to avoid such errors. For example,
ulimit -u 2048add
- jberet-core: core batch runtime engine
- jberet-se: impl classes specific to Java SE runtime environment
- jberet-support: a collection of reusable batch readers and writers (e.g., CSV, fixed length, Excel, Json, XML, Mongo, JDBC, JMS, HornetQ, PDF, etc) for batch applications, and JNDI support
- jberet-rest-api: REST API for batch job management
- jberet-ui: front-end UI web app for batch job management
- jberet-se-bom: a maven BOM to encapsulate all the dependencies required by JBeret Java SE.
- test-apps: test applications
- tck-porting-impl: support running Jakarta Batch TCK with JBeret in Java SE
- wildfly-jberet-samples: Sample batch processing apps that can be deployed to WildFly or JBoss EAP 7
- quarkus-jberet: The Quarkus JBeret Extension adds support for Jakarta Batch applications
- JBoss Tools for Batch (Eclipse extensions, Wizards, Visual editing, etc)

- JsonItemReader, JsonItemWriter
- CsvItemReader, CsvItemWriter
- XmlItemReader, XmlItemWriter
- MongoItemReader, MongoItemWriter
- JNDI lookup of Jackson JsonFactory, MappingJsonFactory & XmlFactory in WildFly for batch reader and writer
- JNDI lookup of MongoClient in WildFly
- job xml files showing the use of various reader/writer configuration properties
- jberet-support module can be installed in WildFly and referenced by multiple apps via either MANIFEST.MF or jboss-deployment-structure.xml

- test apps running in Java SE environment to verify core batch requirements
- test apps running in Java SE environment to verify additional JBeret features (inheritance, scripting support, infinispan job repository, etc)

A note on webapp or Jakarta EE application packaging: Jakarta EE API jars
are already available in the appserver, and should not be included in WAR, JAR, or EAR files. Their maven dependency
scope should be set to provided. In addition, if the application is deployed to JBoss EAP or WildFly, almost all of
the above dependencies are already available as JBoss modules, and should not be duplicated in application package.
