Enterprise COBOL-to-Java Translation Toolkit

The SoftwareMining COBOL-to-Java Translation Toolkit enables organizations to modernize COBOL applications in house with full control over source code, data, and testing. It automatically converts COBOL into clean, object oriented Java code while preserving business logic and functional accuracy. Optional C# generation is also available for .NET use.

Built for enterprise modernization, the toolkit supports millions of COBOL lines and integrates with standard DevOps pipelines. It performs code analysis, documentation, and automated verification to ensure reliable results and maintainable, cloud ready Java systems for deployment on AWS, Azure, or private platforms.

Proven in government, financial, and Fortune 500 projects, SoftwareMining enables in house teams to translate and test COBOL systems efficiently. The toolkit supports multiple COBOL dialects, including IBM z/OS, CICS, RACF, MQ, and JCL, ensuring compatibility across diverse enterprise environments.

Enterprise Data Integrity

Many COBOL systems rely on byte-accurate data definitions where a character may occupy one or more bytes. SoftwareMining preserves byte-level semantics across strings, files, databases, SORT/MERGE, and REDEFINES to prevent subtle data corruption during modernization. This capability has been validated in Mainframe COBOL banking applications migrated to Java that require variable-width character handling, including BIG5, and applies equally to COBOL applications using Japanese, Chinese, and other multi-byte character sets.

Toolkit Features and Capabilities

The SoftwareMining COBOL-to-Java Translation Toolkit provides all the utilities required for large scale mainframe modernization. It automates COBOL analysis, documentation, and code conversion while preserving business logic and data integrity.

• Automated Translation: Converts COBOL programs and COPYBOOKs into maintainable Java code. Optional .NET generation is also available.
• Inventory and Dependency Analysis: Scans COBOL portfolios to identify dependencies, missing files, and program relationships.
• Data and File Conversion: Maps IMS and VSAM data structures to relational models and handles EBCDIC-to-UTF-8 conversion.
• Testing and Verification: Confirms identical runtime behavior between COBOL and translated Java systems.
• Cloud Deployment: Generates applications ready for AWS, Azure, or private cloud environments.
