Questions tagged [pojo]

POJO is an acronym for Plain Old Java Object. The name is used to emphasize that a given object is an ordinary Java Object, not a special object, and in particular not an Enterprise JavaBean.

POJO (Plain Old Java Object) is mainly used to denote a Java object which does not follow any of the major Java object models, conventions, or frameworks such as EJB.

The term continues the pattern of older terms for technologies that do not use fancy new features, such as POTS (Plain Old Telephone Service) in telephony, PODS (Plain Old Data Structures) that are defined in C++ but use only C language features, and POD (Plain Old Documentation) in Perl. The equivalent to POJO on the .NET framework is Plain Old CLR Object (POCO). For PHP, it is Plain Old PHP Object (POPO).
