Each structure is implemented as a Java Class.

Encoding the PDU
Now, we have to transform these Java classes to a PDU

That's it ! We now have a ByteBuffer which is a PDU. MINA, it's up to you ...
Decoding the PDU
Decoding a BindRequest message is a little bit more complicated. We will have to implement a state machine representing all the possible states and transitions, with actions.

Conclusion
The encoding process is simple. One who wants to implement an encoder has to be warned about some tricks :
