Create a kie-core-jaxb module for easier serialization ------------------------------------------------------ Key: DROOLS-960 URL: https://issues.jboss.org/browse/DROOLS-960 Project: Drools Issue Type: Bug Components: core engine, kie server Affects Versions: 6.3.0.Final Reporter: Marco Rietveld Assignee: Mario Fusco Priority: Critical Fix For: 7.0.0.Final Attachments: CoreObject.java, ImplObject.java, JaxbInheritanceTest.java At the moment, the cost of supporting serialization of our command pattern is way too expensive. The hacked-together solution that I'm doing is basically taking {{Command}} implementation classes in the core engines, and then 1. converting those classes to an xsd schema 2. generating new classes from the xsd schema However, this means that I'm constantly wrestling with the core command implementations in order to make sure that they serialize correctly and convert nicely to an xsd schema. Instead, we should have a {{kie-core-jaxb}} module that contains 2 things: 1. The utilties (Java JAXB Adapters) that are used in multiple modules ({{drools-core}}, {{jbpm-human-task-core}}, {{kie-remote-jaxb}}) 2. The Core command serialization implementations. See the attached java files for an example of how we can use inheritance to do what we want. In short: 1. The {{CoreObject}} is the Command DTO class, that would be in {{kie-core-jaxb}} 2. The {{ImplObject}} is the Command implementation, that would be in a {{drools-core}}, {{jbpm-human-task-core}} or other core module. This class would extend the {{CoreObject}} class, but also make sure to use the same {{@XmlRootElement}} name value.
