HOW-TO Define behavior when a resource is missing

JasperReport define 4 possible actions when a resource is missing. These actions are described below.

Using the DynamicReportBuilder

DynamicReportBuilder setWhenResourceMissing(byte whenResourceMissing)
  • DJConstants.WHEN_RESOURCE_MISSING_TYPE_EMPTY: Leaves an empty space
  • DJConstants.WHEN_RESOURCE_MISSING_TYPE_ERROR: Throws an exception
  • DJConstants.WHEN_RESOURCE_MISSING_TYPE_KEY: Show the key of the missing resource
  • DJConstants.WHEN_RESOURCE_MISSING_TYPE_NULL: Return null.

These convenient methods are also available:

setWhenResourceMissingLeaveEmptySpace(), setWhenResourceMissingThrowException(), setWhenResourceMissingShowKey() and setWhenResourceMissingReturnNull()
