Generating Java Object API Code Using the Code Generation Utility

Use the Code Generation Utility to generate object API code containing mobile business object (MBO) references. This method of generating code allows you to automate the process of code generation, for example through the use of scripts.

Prerequisites
  • Use SAP Mobile WorkSpace to develop and package your mobile business objects. See SAP Mobile WorkSpace - Mobile Business Object Development > Develop > Developing a Mobile Business Object.
  • Deploy the package to the SAP Mobile Server, creating files required for code generation from the command line. See SAP Mobile WorkSpace - Mobile Business Object Development > Develop > Packaging and Deploying Mobile Business Objects >Automated Deployment of SAP Mobile WorkSpace Projects.
Task
  1. Locate <domain name>_package.jar in your mobile project folder. For the SMP101 example, the project is deployed to the default domain, and the deploy jar file is in the following location: SMP101\Deployment\.pkg.profile\My_SAP_Mobile_Server\default_package.jar.
  2. Make sure that the JAR file contains this file:
    • deployment_unit.xml
  3. Use a utility to extract the deployment_unit.xml file to another location.
  4. From SMP_HOME\MobileSDK23\ObjectAPI\Utils\bin, run the codegen.bat utility, specifying the following parameters:
    codegen.bat -java -client -android -ulj deployment_unit.xml [-output <output_dir>] [-doc]
    • The -output parameter allows you to specify an output directory. If you omit this parameter, the output goes into the SMP_HOME\MobileSDK23\ObjectAPI\Utils\genfiles directory, assuming codegen.bat is run from the SMP_HOME\MobileSDK23\ObjectAPI\Utils\genfiles directory.
    • The -doc parameter specifies that documentation is generated for the generated code.
    Ignore these warnings:
    log4j:WARN No appenders could be found for logger ...
log4j:WARN Please initialize the log4j system properly.
