Standard framework
Banks adopt it as their standard framework for online and batch development.
Technology Platforms
Application Framework · BX‑M / BX‑CM
Java application frameworks and tooling for teams building and operating banking systems.
BX-M targets on-premise development and BX-CM cloud environments. BX-CBP-based offerings require one of them; each also provides batch support and can be evaluated separately.
02 / Role and where it applies
Where BX-M and BX-CM sit
Inside BX-CBP-based offerings
BX-CBP-based suites and solutions require BX-M or BX-CM as their Java development platform.
On-premise or cloud
BX-M serves on-premise development environments and BX-CM cloud development environments.
Where extensions are built
Controlled Extension and Additional Development for BX-CBP-based offerings are built on it.
03 / Key functions
What BX-M / BX-CM does and how it works
Application framework
Spring-based, with hierarchical transaction processing so business rules live in one place.
Batch engine and scheduler
Spring Batch based, with parameter management, execution monitoring and intervention.
Hot Deploy and staged release
Supported service changes reach the running system after Pre-Deploy and Application Staging.
Hot Deploy applies within the supported change scope and validated deployment procedures. Supported product versions and edition compatibility are confirmed for the target deployment.
BX Studio
Eclipse-based environment that links design and source in both directions.
Runtime control
Timeouts, record limits and error thresholds that stop affected transactions.
Standards and security
Code generation, inspection and impact analysis, plus masking and encryption APIs.
BX-CM adds field-level encryption; edition-specific coverage is confirmed for the target deployment.
Design, build, deploy and operate on one Java platform.
BX Studio links design and source; wizards generate code and inspection blocks non-standard code. The runtime controls online and batch work, and Hot Deploy supports changes to running services within its supported scope.
01Application framework
What the platform provides
A Spring-based Java framework with hierarchical transaction processing, so business rules live in one place, not per service.
Design and operation
Spring-based, with hierarchical transaction processing so business rules live in one place.
Conditions
BX-M or BX-CM is chosen to match the bank’s development environment.
02Batch engine and scheduler
What the platform provides
A Spring Batch based engine for financial-scale volumes, with parameter management, execution monitoring and real-time intervention.
Design and operation
Spring Batch based, with parameter management, execution monitoring and intervention.
Conditions
Supported product versions and edition compatibility are confirmed for the target deployment.
03Hot Deploy and staged release
What the platform provides
Supported changes reach running services through Hot Deploy, with Pre-Deploy and Application Staging first; bytecode method versioning works underneath.
Design and operation
Hot Deploy supports changes to running services within the supported change scope; Pre-Deploy prepares changes before activation and Application Staging tests under production conditions first. Product and rule changes thus reach production between batch windows.
Conditions
Hot Deploy applies within the supported change scope and validated deployment procedures. Supported product versions and edition compatibility are confirmed for the target deployment.
04BX Studio
What the platform provides
Eclipse-based: bidirectional design-to-source linkage, Application Architecture map, IO and DBIO Editors, Service Flow Designer, GUI testers.
Design and operation
BX Studio, Eclipse-based, generates source from design and regenerates models from production source, so documentation matches the code. Editors cover I/O layouts, database access and service flows; testers run alongside.
Conditions
The supported tools and edition compatibility are confirmed for the target deployment.
05Runtime control
What the platform provides
Timeouts cancel in-flight SQL, record limits stop a query flooding memory and debug logging switches on selectively. Above an error threshold, administrators are alerted and affected transactions stop automatically.
On-premise or cloud development environment
BX-M is for on-premise development environments, BX-CM for cloud, with Spring Boot runtime, microservice support and BX Bridge.
Conditions
Java 21, Spring Boot 3 and supported application servers are confirmed against the product version and edition for the target deployment.
06Standards and security
What the platform provides
Code generation, inspection and impact analysis, plus masking and encryption APIs for customer data; BX-CM adds field-level encryption.
Design and operation
Template wizards generate source per pattern, code inspection blocks non-compliant commits and the Application Architecture map governs packages. Impact analysis shows what a model change affects before deployment.
Conditions
BX-CM adds field-level encryption; edition-specific coverage is confirmed for the target deployment.
04 / Relation to other offerings
How BX-M / BX-CM relates to other products
Required: one Java development platform in every BX-CBP-based suite and solution.
Every BX-CBP-based suite and solution requires BX-M (on-premise) or BX-CM (cloud), separately licensed products on which Controlled Extension and Additional Development are built. Select the platform for the target environment. Both are sold separately in Korea, Japan and Southeast Asia.

Composition applies to BX-CBP-based suites and solutions. Whether BX-M and BX-CM are used together is confirmed per engagement.
BX-CA
BX-CA, an AI development-support product, can connect to the BX-CM framework tools, as at Woori Bank.
Cloud & DevOps Platform
BX-CM supports application development. Cloud & DevOps Platform is a separate product for Kubernetes deployment and platform operations.
Application Monitoring
Application Monitoring is also separate; framework use does not establish monitoring coverage.
