Minor changes are required, related with redirecting class imports from JADE to SAJaS or vice-versa. | The same JADE-based implementation can be used to run the MAS in JADE or its equivalent simulation in SAJaS.

| | An additional change to take into account is that although the import of the ''jade.core.AID'' class should not, in general, be redirected to ''sajas.core.AID'', any direct instantiation of ''AID'' should be made in the SAJaS' version of this class (which extends JADE's one). Example: |
| | |
| | <code> |
| | import sajas.core.Agent; |
| | import jade.core.AID; |
| | |
| | ... |
| | |
| | ACLMessage m = new ACLMessage(ACLMessage.REQUEST); |
| | m.addReceiver(new sajas.core.AID(name, false); |
| | ... |

| * //Blocking approaches//: JADE includes a few blocking approaches for agent interaction, namely based on the ''blockingReceive'' and ''doFipaRequestClient'' methods in the ''Agent'' class. These methods block agent execution until a matching message is received or a complete protocol is concluded. Given the single-threaded approach of SAJaS, or more precisely of the simulation frameworks (such as Repast) it may be aligned with, blocking approaches do not work. \\ Another typical usage of blocking approaches in JADE concerns (de)registering and searching the DF (JADE's yellow page service), for which a number of blocking methods are available in the ''DFService'' class. Given their quite common usage, these methods are still available in SAJaS, where they have been reimplemented so that they do not block, while achieving the desired functionality. | * //Blocking approaches//: JADE includes a few blocking approaches for agent interaction, namely based on the ''blockingReceive'' and ''doFipaRequestClient'' methods in the ''Agent'' class.

| | * //Mobility between containers//: Mobility-related methods are not supported yet, because SAJaS simplifies the usage of containers. |
