JR41685: CMVC 217606 - PREVENT A CLASSCASTEXCEPTION WHILE COMPOSING AN ORDER WHERE PAYMENT PROTOCOL DATA IS STORED IN A NON STRING TYPE

7.0.0-WS-WCServer-FP009

APAR status

• Closed as program error.

Error description

• Shoppers are trying to review an order in the storefront reach a
  generic error page.  The logs indicate that there was a
  CommandException while additional traces show that the root
  cause is a ClassCastException.
  
  The problem occurs since the GetOrder service, while composing
  the response BOD will try to include payment data, if such data
  exists.  While adding the protocol data into the response BOD,
  it assumes that all protocol data (PPCEXTDATA) is stored as type
  String, while it is possible to store this data in other java
  data types.
  
  The following is an example set of logs that show the error:

Local fix

• This problem only occurs if the data type of the payment
  protocol data is a non-String type.  Adjusting your payment
  plugin to only use the String type can prevent this problem.
  

Problem summary

• USERS AFFECTED:
  Users who use a customized payment plugin which stores protocol
  data in a non-string type and who use the GetOrder service on
  orders which have such data stored against it.
  
  PROBLEM ABSTRACT:
  ClassCastException is thrown while executing a GetOrder service
  request where the payment protocol data is stored in a
  non-String type.
  
  BUSINESS IMPACT:
  The GetOrder service returns in error for any order that has
  this type of data associated to it.
  
  RECOMMENDATION:
  

Problem conclusion

• The code was updated to be type sensitive and correctly handle
  the data based on the type it was defined to be as per the
  PPCEXTDATA.ATTRIBUTETYPE column.
