Driving an Interaction with the EIS

Context

If the resource adapter implements interaction-related functions, you can drive an interaction with the underlying EIS. Driving an interaction implies calling a specific function of the EIS from your application component.

To execute an interaction, you use an InteractionSpec, which defines the properties of the EIS function.

Procedure

Get a connection to the EIS.

Create an Interaction and an InteractionSpec instance, and set the specific properties defined in the InteractionSpec.

Sample Code

                     Interaction inter = conn.createInteraction();
InteractionSpec interSpec = new InteractionSpec();
interSpec.setFunctionName("XXX");

Create the input record for the execution of the interaction, and an empty output record to hold the output of the interaction.

Sample Code

                     InputRecord inRec = new javax.resource.cci.Record();
inRec.setProperty(); // set the properties for the input record
...
OutputRecord outRec = new javax.resource.cci.Record();

Execute the interaction.

Sample Code

                     inter.execute(interSpec, inRec, outRec);

Finally, close the interaction and the connection as well.

Sample Code

                     inter.close();
...
conn.close();
