Driving an Interaction with the EIS 

Use

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

       1.      Get a connection to the EIS.

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

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

 

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

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

 

       4.      Execute the interaction.

inter.execute(interSpec, inRec, outRec);

 

       5.      Finally, close the interaction and the connection as well.

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