New Batch Artefact wizard ------------------------- Key: JBIDE-18950 URL: https://issues.jboss.org/browse/JBIDE-18950 Project: Tools (JBoss Tools) Issue Type: Sub-task Components: batch Affects Versions: 4.3.0.Alpha1 Reporter: Viacheslav Kabanovich Assignee: Viacheslav Kabanovich Labels: new_and_noteworthy Fix For: 4.3.0.Alpha1 There are about 20 artefacts in Java EE Batch: Batchlet; Checkpoint Algorithm; Decider; Item Reader; Item Writer; Item Processor; Partition Analyzer; Partition Reducer; Partition Collector; Partition Mapper; Partition Plan; Chunk Listener; Item Process Listener; Item Reader Listener; Item Writer Listener; Job Listener; Step Listener; Retry Process Listener; Retry Read Listener; Retry Write Listener; Skip Process Listener; Skip Listener; Skip Write Listener. We may have one wizard for each, or some of this artefacts. However, there is so much common in them that it makes sense also have one wizard with list choice of artefact. When a specific artefact should be created from the context of Batch XML editor, this wizard can be invoked with selection of that artefact (list of artefacts may be disabled or hidden). 1. Artefact implements a specific Java interface (for interfaces that have more than 1 method, there is optional abstract class to extend that implements rarely overridden methods); 2. Reference name should be provided for each artefact. There are 3 options: - An implementation of Batch runtime may define its own way of matching class to name. For example, CDI uses javax.inject.Name; - META-INF/batch.xml - by default, when first 2 options failed reference name is tried as the qualified class name. 3. Artefact class may declare fields, with values to be injected from properties set in job xml element referencing that artefact: {code} @Inject @BatchProperty(name="property1") String property; @Inject @BatchProperty String property2; {code} Thus, the wizard will have inputs as follows: - Artefact: [combo] - Source folder: [as in New Java Class wizard] - Package: [as in New Java Class wizard] - [radio] implement interface [radio] extend abstract class (if class is not available, the option is disabled) - Reference name: (block of inputs) | - [radio] Annotation Named [radio] batch.xml [radio] Qualified name | - Name: [text] (for first 2 options filled with default value; for the last option disabled) - Properties: [table editor with 'Property name' and 'Field name' columns] Some more inputs may be inherited from New Java Class wizard, if default values are not enough.
