Description copied from interface: CallableProcessingInterceptor

Invoked from a container thread when an error occurred while processing the async request before the Callable task completes. Implementations may return a value, including an Exception, to use instead of the value the Callable did not return in time.

The default implementation always returns CallableProcessingInterceptor.RESULT_NONE.

Specified by:

handleError in interface CallableProcessingInterceptor

Parameters:

request - the current request

task - the task for the current async request

t - the error that occurred while request processing

Returns:

a concurrent result value; if the value is anything other than CallableProcessingInterceptor.RESULT_NONE or CallableProcessingInterceptor.RESPONSE_HANDLED, concurrent processing is resumed and subsequent interceptors are not invoked

Throws:

java.lang.Exception - in case of errors
