MBO

A developer's deep dive into the four-file MBO pattern behind every Maximo object, how MAXOBJECT.CLASSNAME links to the MBO Set, and how a PLUS extension layers on.

The reference every Maximo developer bookmarks: the complete PLUS prefix directory (PLUSA through PLUSV, TLOAM, custom), which prefixes are included capabilities versus paid add-ons versus legacy, the five-layer extension hierarchy, and exactly how Maximo stitches multiple add-ons into one MBO inheritance chain — with the WorkOrder and Asset chains resolved step by step.

A developer's deep dive into product.xml — the extension control file behind every Maximo add-on. Learn the anatomy of mboset, mbo, class, field, and bean declarations, why alphabetical prefix order matters, what bytecode injection does at build time, and how the resolved top-of-chain class lands in MAXOBJECT.CLASSNAME so you can predict super() behavior.

A developer's deep dive into how IBM Maximo add-ons and industry solutions extend the core through Java — PLUS prefixes, MBO inheritance chains, product.xml, bytecode injection, the compatibility matrix, the MAS 9 Customization Archive, and the Java 17 shift.
