how to ignore some exceptions in sap cpi

Hi Team,
Am working on a requirement where i need to implement an condition in exception where i need to ignore two specific condition of exceptions in the iflow and pass it as successful.
two conditions of exceptions are :"javax.servlet.ServletException: Error during write of the response: , cause: java.io.IOException: Connection reset by peer" and "javax.servlet.ServletException: Error during write of the response: , cause: java.io.IOException: Broken value".

For now am using exceptional subprocess for collecting all the exceptions.Do let me know how to handle it please
