Abstract	Java on z/OS has matured into a robust and strategically valuable platform for running enterprise-grade applications and modernizing legacy applications to enable seamless integration with the surrounding applications built using modern technologies. This paper explores the technical foundations and practical deployment models for Java on z/OS, including standalone batch execution, COBOL interoperability, CICS integration, and modern service-oriented architectures using z/OS Connect and Liberty. This paper also outlines hybrid execution options using Linux-based technologies on IBM Z, such as zVM, zKVM, zCX, and zLinux. This paper also provides brief comparisons with distributed and cloud platforms and performance and cost efficiency metrics, highlighting Java's strengths on z/OS, such as zIIP offloading and co-located data processing. Real-world configuration examples, coding practices, and architectural insights are included to help developers and architects maximize value on IBM Z.
