Overview of Exception and error Handling in Tibco BW:

PALETTES IN TIBCO BW FOR EXCEPTION HANDLING:

CATCH

GENERATE ERROR

RETHROW

SOAP SEND FAULT

SEND EXCEPTION

CATCH :

ACTIVITY DESCRIPTION:

The catch activity is used when an unhandled exception occurs

Using this we can either specify a particular exception that needs to be caught or we can specify all unhandled exceptions

More than one catch activity can be used but each activity should handle a unique exception type

GENERATE ERROR:

ACTIVITY DESCRIPTION:

This palette generates an error and causes an error transition if any error transition is present else it stops the execution of the process

This is generally used in a group activity or in a called process

RETHROW:

ACTIVITY DESCRIPTION:

This activity is always preceded by the Catch activity

This is used to rethrow the exception identified by the catch activity

This activity does not involve any input or output

SOAP SEND FAULT:

ACTIVITY DESCRIPTION:

This activity sends a SOAP fault to the client during the occurrence of an error in the SOAP request

It is used when a SOAP event source process starter handles incoming SOAP requests

This activity cannot be used if the SOAP request is one way

This activity requires fault code and fault string as inputs

For example ‘client’ can be used for client faults and ‘server’ can be used for server faults

SEND EXCEPTION TO ADAPTER REQUEST:

ACTIVITY DESCRIPTION:

This activity captures an exception and sends it to the adapter.

We can use the Adapter Request-Response Server as a starter process and use the Send Exception To Adapter Request in the same process

If any exceptions occurred in the Adapter Request-Response Server, then the exceptions are captured by this palette
