The accelerating pace of digital transformation has compelled enterprises to deliver software at unprecedented speed while simultaneously addressing escalating security threats, regulatory pressures, and software supply chain risks. Within this context, Java-based enterprise systems remain foundational to mission-critical applications across finance, healthcare, telecommunications, and government sectors. However, traditional security models—often reactive, siloed, and detached from development workflows—are no longer sufficient to protect complex, continuously evolving Java ecosystems. This research presents a comprehensive, theoretically grounded examination of DevSecOps as an integrated paradigm for embedding security, compliance, and quality assurance throughout the continuous delivery lifecycle of enterprise Java applications. Drawing strictly from authoritative industry and academic references, this study elaborates on secure coding principles, automated security testing, dependency and supply chain risk management, compliance-as-code, and organizational transformation required to operationalize DevSecOps at scale. The article advances an original synthesis by connecting classical continuous delivery theory with modern security automation practices, emphasizing non-containerized and mixed Java version environments common in large enterprises. Through detailed descriptive analysis, the research highlights how static analysis, software composition analysis, vulnerability scanning, and policy-driven governance can be orchestrated within CI/CD pipelines without undermining developer productivity or delivery flow. The findings underscore that DevSecOps maturity is less a function of tooling alone and more a socio-technical evolution encompassing culture, process, architecture, and leadership. By articulating limitations, counter-arguments, and future research directions, this article contributes a holistic, publication-ready perspective for researchers and practitioners seeking to design resilient, compliant, and scalable DevSecOps pipelines for enterprise Java ecosystems.
