For each table in a MIB, mibgen generates an MBean representing a table entry. These skeletal MBeans need to be completed by adding implementation specific code (access methods). The generated code is initialized with default values for table entry fields. Therefore, if you compile the generated code directly, you will obtain a running agent. In this case, values returned by the agent when querying the MIBs will not be meaningful.
MBeans generated from table entries are named using the entry names specified in the MIB definition.
