Optimizing ESB/BPEL by Using Java

Slide 3

Optimizing ESB / BPEL Using Java• Why

– View end to end instance data in ESB Control– Increased performance due to not using HTTP/SOAP – Execute on the same JTA transaction– Click through to/from BPEL and ESB Control instance data

• How– Install BPEL and ESB in the same container

• SOA Suite install – basic or advanced• Separate standalone Mid tier installs into same OC4J

– Inbound: BPEL -> ESB• Force BPEL to use __ESB WSDL binding

– Outbound: ESB->BPEL• Replace ESB SOAP Service with direct routing rule

• Use Cases– SOA OrderBooking Demo

• ESB Inbound: ESB invoking BPEL OrderBooking process• ESB Outbound: BPEL invoking ESB OrderFullfillment flow
