Convert ColdFusion to Java
Move ColdFusion applications onto Java without losing the business rules buried in years of CFML tags, CFCs, and tag-based templates. Spec-first, validated, and governed end to end.

Six reasons to move off ColdFusion
ColdFusion still serves working applications, but the platform risk and licensing cost compound every year.
Licensing cost compounds
Adobe ColdFusion carries per-server licensing that scales with your footprint. Java runs on an open runtime, removing a recurring line item that grows with the estate.
Same functionality, new platform
Migration does not mean rebuilding features. Forge reconstructs what your CFML templates and CFCs actually do into a Living Spec, then generates Java that preserves that behavior.
Talent pool and hiring
ColdFusion expertise is increasingly scarce and concentrated. Java has one of the deepest hiring pools in enterprise software, which lowers key-person risk immediately.
Security and patch cadence
Actively maintained Java frameworks receive the patches, scanners, and audit tooling that aging ColdFusion runtimes no longer get on the same cadence.
Architecture preserved or improved
Keep the structure that works, or restructure deliberately. The Living Spec makes that an explicit decision, not an accident of the rewrite.
Ecosystem and integration
Java slots into modern CI/CD, containers, and API ecosystems that tag-based ColdFusion applications were never designed for.
What changes when you move to Java
The shift is more than syntax. Request handling, data access, and runtime assumptions all move, and each one needs an explicit mapping.
- 01
Language & paradigm
Tag-based CFML templates and CFC components are restructured into idiomatic Java classes and Spring controllers rather than transliterated tag for tag.
- 02
Data access
cfquery blocks and inline SQL are re-expressed against JDBC and JPA repositories, with parameter binding and type mappings resolved up front instead of at runtime.
- 03
Runtime & packaging
Applications served by the ColdFusion engine become standard JVM deployables, with session and application scope mapped onto explicit Spring-managed state.
- 04
Tooling & workflow
ColdFusion Builder and engine-specific tooling give way to standard IDEs, Maven or Gradle builds, automated tests, and CI pipelines.
Component and query declaration

<cfquery name="q" datasource="crm">
SELECT id, name, balance FROM customer
WHERE id = <cfqueryparam value="#arguments.custId#">
</cfquery>
<cfreturn q>
</cffunction>
</cfcomponent>@Repository
public class CustomerRepository {
private final JdbcTemplate jdbc;
public Customer getCustomer(long custId) {
return jdbc.queryForObject(
"SELECT id, name, balance FROM customer WHERE id = ?",
new CustomerRowMapper(), custId);
}
}How the migration works
From import to verified output, every step is scored, specified, and tracked.
Import ColdFusion
Your existing ColdFusion codebase is ingested as-is, .cfm templates and CFC components included. No prior documentation needed.
ForgeScore assessment
Scored across 8 engineering-health dimensions, including template-embedded logic and scope-resolution risk, before you commit to anything.
Approved specification
Business rules, including logic embedded in .cfm templates and undocumented CFC behavior, are reconstructed from source into a spec your team approves.
Work orders
The spec becomes Build, Migrate, and Decommission work orders, scoped and sequenced.
Verified & shipped
Each Migrate work order is checked against the original ColdFusion behavior, including query results and scope handling, before it ships as Java.
Works in your editor
Work orders connect into Claude Code, Cursor, Windsurf, and other AI code editors over MCP, so the governed spec travels with you instead of staying in a document.
From finding to work order
Every ColdFusion import is scored across 8 engineering-health dimensions, then broken into Build, Migrate, and Decommission work orders. Here is what that looks like for a data-access finding.
ForgeScore findingMedium severity finding
Data Weight54
How data is modeled, moved, and owned. Moderate score: cfquery blocks embed SQL directly inside templates, so data access and presentation must be separated before either can move.
Migration work orderMigrate
Migrate: CustomerService.cfc
Re-express the customer service component as a typed Java repository with equivalent query behavior. Includes verification against the original ColdFusion output before this work order is marked complete.
Common challenges
Most ColdFusion migrations fail for the same handful of reasons, and it is rarely the technology itself.
Logic embedded in templates
Business rules live inside .cfm view templates mixed with presentation markup, so behavior and layout have to be separated before either can move.
Dead & duplicated code
Years of maintenance obscure what is genuinely still in use versus what can be retired, especially across copied template variants.
Implicit typing & scopes
ColdFusion's loose typing and implicit scope resolution rarely map cleanly onto Java's type system without explicit decisions about nullability and precision.
No test coverage
Legacy ColdFusion applications usually ship with nothing to prove behavioral parity against.
Frequently asked questions
How long does migrating ColdFusion to Java take?
It depends on estate size and coupling. A ForgeScore assessment in the first few minutes gives you a concrete, evidence-based range before you commit, based on complexity and dependency analysis rather than a guess.
Do we need documentation of the existing ColdFusion system?
No. Forge works from the source itself, reconstructing the business rules into a Living Spec. Missing documentation is the normal starting condition for these migrations, not a blocker.
Will the generated Java be maintainable?
Yes. Output is idiomatic Java structured against the approved specification rather than a line-by-line transliteration of CFML tags, so your existing JVM engineers can read and extend it.
How much of the migration is automated?
Automation depends on the complexity and coupling of your specific codebase. ForgeScore quantifies this for your estate before you commit, so the estimate is grounded in evidence.
How do you prove the migrated system behaves the same?
Every Work Order is validated against the Living Spec and, where legacy outputs are available, against them directly, so parity is demonstrated rather than assumed.
See your ForgeScore before you commit
Every ColdFusion-to-Java project on Forge starts the same way: your codebase is imported, scored across eight engineering-health dimensions with ForgeScore, and reconstructed into a Living Spec before a single line of Java is generated. That is what keeps behavior intact and architecture on plan.
