COBOL to Java & C#
• Predictable & Repeatable
SoftwareMining's automated, rule-based COBOL-to-Java and COBOL-to-C# Conversion Toolkit converts complete enterprise COBOL applications into maintainable Java or C# source code. It is designed for large application portfolios rather than the conversion of isolated source files.
Enterprise customers and system integrators can download the COBOL-to-Java and COBOL-to-C# Conversion Toolkit and operate it within the client's own infrastructure. The toolkit combines application analysis, dependency reporting, documentation, automated conversion, runtime libraries and comparison utilities, allowing project teams to control source code, business data, functional-equivalence testing and deployment. Generated applications can use standard development and DevOps processes and run on AWS, Azure, Kubernetes, private cloud or on-premises infrastructure.
SoftwareMining tools have been used in government, financial services and Fortune 500 modernization projects. Technical coverage for COBOL-to-Java conversion includes IBM z/OS COBOL applications using CICS, JCL, VSAM, DB2 and IMS. Support is also available for selected RACF and MQ integration requirements.
Enterprise COBOL-to-Java conversion involves more than translating individual source statements. The complete application and its platform dependencies must be analysed, converted, compiled and validated against the original COBOL system.
SoftwareMining analyses COBOL programs, copybooks, call relationships, data definitions, files, database access, batch jobs and online transactions. This identifies missing components and establishes the application scope before translation begins.
The rule-based translator converts COBOL business logic into Java source code using predefined and repeatable transformation rules. Copybooks and shared data structures are generated as reusable Java classes rather than duplicated across individual programs.
Applications may depend on technologies surrounding the COBOL language. SoftwareMining provides translation and migration support for IBM CICS, IMS, DB2 embedded SQL, VSAM and KSDS files, JCL-controlled batch processing and other supported platform services.
Java does not natively provide all COBOL data and execution behaviour. SoftwareMining runtime libraries support required features such as packed-decimal arithmetic, PICTURE formats, REDEFINES, OCCURS DEPENDING ON, record layouts, program calls, file operations and transaction processing.
The generated Java application is compiled and executed using representative business data. Its files, reports, database updates, return codes and transaction results can then be compared with the original COBOL application to validate the required business behaviour.
The translated application can be integrated with the customer's selected Java architecture and development processes. Deployment options include AWS, Azure, Kubernetes, private cloud and on-premises infrastructure, while the generated source code remains under customer control.

COBOL records can combine fixed-width character fields, multi-byte encodings, packed-decimal values, binary data, REDEFINES and other byte-sensitive structures. SoftwareMining uses COBOL data definitions to preserve field boundaries and data semantics across file processing, database access, SORT/MERGE operations and translated application logic.
This capability has been used in mainframe banking applications involving BIG5 variable-width character data. Support for Japanese, Chinese and other multi-byte character sets is assessed and configured according to the source encoding, COBOL record definitions and target environment.
Watch the SoftwareMining toolkit analyse a COBOL application, generate flowcharts, identify dependencies and prepare programs for translation to Java. The demonstration includes call-chain analysis, data-access identification and rule-based conversion patterns.
