When choosing how to deploy the JVM COBOL run-time system that is required by JVM application code, consider the deployment options illustrated in this diagram:
- Shared Runtime Deployment Style
- Deploy the run-time system separately, as a shared module or object in your application server.
- Per Bean Runtime Deployment Style
- Package the run-time system in a deployed archive file, such as an enterprise archive file (.ear) or web archive file (.war).
Each Runtime Deployment Style has its advantages:
| Shared
|
Per Bean
|
- Uses less memory, because the run-time file (mfcobolrts.jar) is shared by all applications.
- Tracing can be performed centrally.
- For application servers that provide versioning, you can deploy multiple versions of the run-time system.
|
- Administrative rights are not required to configure the application server.
- For application servers that do not provide versioning, you can deploy different applications that use different run-time systems.
- Remote deployment is easier as all required resources are self-contained.

In this tutorial, you deploy your JVM COBOL runtime using the Per Bean Runtime Deployment Style, meaning that the runtime packaged as an archive file and deployed with the application.
