Where Java fits
Maintaining a business service whose existing rules should survive modernization.
When to choose another approach
A language upgrade does not prove dependencies, integrations or business behaviour remain correct.
Worked example and evidence
Fictional wholesaler: expose an existing Java order calculation through a documented API while retaining approved discount rules.
What you need to supply
Source/build access, JDK distribution/version, dependencies, anonymized calculations and integration owners.
What acceptance should demonstrate
Rebuild from source, reproduce approved totals and compare API responses before release.
Running costs and responsibilities
Record runtime support terms, patch ownership, hosting and rollback procedure.
Technical scope to confirm
Confirm support and licensing for the actual JDK distribution and version.
A proposal should identify the systems and data, direction of sync, access feasibility, failure handling, named owners and included deliverables. Listing this technology does not imply a prebuilt connector, vendor partnership or included feature.
Can current business rules be retained?
Start with examples signed off by the business owner. Preserve verifiable rules and explicitly resolve undocumented exceptions.
