Integration

Hi,

I am trying to invoke an ESB through an other ESB, which I developed using JDeveloper. I am getting the following error

<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><env:Header/><env:Body><env:Fault xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><faultcode>env:ESBMessageProcessingFailed</faultcode><faultstring>ESB Dispatch failed with error Cannot get part 'rootId'. Part was not found in message; nested exception is:
org.collaxa.thirdparty.apache.wsif.WSIFException: Cannot get part 'rootId'. Part was not found in message</faultstring></env:Fault></env:Body></env:Envelope>

I am not getting an error when I invoke the second ESB directly. I am not sure what the issue is,.. Does anyone have any idea? Please do respond.

Thank you.
