JSR 181 is used to expose a POJO as a service on the JBI bus.
The pojo or pojoClass is the POJO class that acts as a service.
The class is the class name of your POJO with its package. The location is the path to the JAR containing the class you want to use or the directory of your class.
For example,
path_to_my_jar
.jar
and the class property is my_package.my_supackage.my_class
path_to_my_package
and the class property is my_package.my_supackage.my_clas
