Developers need to address issues such as data mapping, protocol compatibility, and performance optimization to maintain reliable and efficient integration. Additionally, understanding both Java and mainframe environments is crucial, as troubleshooting can require knowledge of mainframe batch jobs, COBOL code, or CICS transactions alongside Java frameworks. Collaborative work with mainframe specialists and clear documentation are essential for overcoming these challenges.
