Suppressing the Selection Failure exception in Assign activity – Oracle SOA Suite

Suppressing the Selection Failure exception in Assign activity – Oracle SOA Suite

This post will explain how to suppress the Selection Failure exception BPEL Assign activity – Oracle SOA Suite
In BPEL Assign activity if the xpath returns empty result then SelectionFailure RuntimeFault will be thrown by the engine.

But some cases we may need to suppress the selectionFailure error while assigning the optional elements.

In my case I have a assign activity that will mapthe elements  input and input1 from inputVariable to result and result1 of outputVariable.

The input2 is optional and somecases input2 element  will not be available in the request payload.

Don't support MessageVariable in fromPart - Oracle SOA Suite

Don't support MessageVariable in fromPart -  Oracle SOA Suite:

This error will be thrown while invoking the service with Multipart Message type and the receive activity uses the fromPart to retrieve the parts data and assign to a variables created based on message type or invoke activity uses toPart to assign the data to parts based message type variable.

To resolve this whenever retrieving or assigning values to parts in receive/invoke activity through fromPart or toPart use the element based variables instead using the message type based variable.
