Depending on the technique used for exchanging data with the SDP server (application connection method), custom adaptors can be classified into the following two types:
Figure 6-2 RMI connection custom adaptor
Figure 6-3 In-process connection custom adaptor
When using custom adaptors, it is possible for a data transmission application and a data reception application to use different data exchange methods.
For example, as shown in the figure below, you can create the data transmission application as an RMI connection custom adaptor and the data reception application as an in-process connection custom adaptor, or create the data transmission application as an in-process connection custom adaptor and the data reception application as an RMI connection custom adaptor.
