Data Types and Serialization

  1.         Create POJO class/classes with JAXB Mappings. This can be done in two ways as described below

    • First, create POJO classes and add JAXB Mapping later as shown in this example. Then, create ObjectFactory.java class in the same package, where POJO classes are present.

    • (or) If you have XSD which describes the structure, use XJC Java Tool to generate JAXB Mappings. Refer to Generating_JAXB_classes_from_XSD.

  • Implement   hashCode and equals methods in your data model classes. Those methods can be generated by IDE, JAXB or written by hand. TIPS:

    • Namespace is required in order to provide mapping information to JAXB transformer (Refer step 2.)

    • Do not alter ObjectFactory.java file. Below is the code for ObjectFactory.java

  1.           Next, provide JAXB Mapping to the Transformer which is responsible for converting Java object to JSON.    Create transformer.properties file in src directory with package and namespace details as shown below.                           

pkg.com_sabre_redapp_example3_desktop_template=template      1
ns.com_sabre_redapp_example3_desktop_template=http://redapp.sabre.com/example3/desktop/template     2

TIPS:

o      Package name should be same where JAXB Mapping classes are provided. Key should be in the format of key.<plugin-name-with-underscores>.

o      Namespace value should be the same as the one which is provided in JAXB mapping classes. Key should be in the format of ns.<plugin-name-with-underscores>.

  1.       Update MANIFEST.MF file with dependencies and other configurations.

TIPS:

  • Add com.sabre.edge.dynamo.transformer to bothRequire-BundleandEclipse-RegisterBuddy. This is required for the pre-load JAXB Mappings.

Add any other require bundle from target platform that are required for compilation.

  • UpdateBundle-Activatorwith plugins Activator class including package as shown above.

  • Add com.sabre.edge.dynamo.ext.cdm, 'com.sabre.edge.dynamo.services.impl','com.sabre.edge.dynamo.services.common'  toRequire-Bundle.

    Add any other require bundle from target platform that are required for compilation.

  • Add callback service definition ‘OSGI-INF/TemplateFlowExtensionPointService.xml’ to Service-Component.
