Requirement to be fulfilled using PI 7.3 Java only installation

Hi Experts,

We have a requirement depicted as below and need to confirm if the same is possible in PI 7.3 JAVA only

installation where there is no possibility of using ccBPM.

Step 1. System A sends web service request to PI,

Step 2. PI sends the request to System B which is a web service call

Step 3. System B sends response back to PI

Step 4. PI gets the response from System B, this response needs to transformed and mapped and sent to System C web service request.

Step 5. The response from System C needs to be sent back to System A which initiated the call.

Please give a thought based on your experience and expertise if this is possible; given the limitation of java only installation which is without ccBPM.
