Improved error information for unenhanced classes.
---------------------------------------------------
Key: OPENJPA-1778
URL: https://issues.apache.org/jira/browse/OPENJPA-1778
Project: OpenJPA
Issue Type: Bug
Components: jpa
Affects Versions: 2.0.0
Reporter: Rick McGuire
Priority: Minor
The exception message issued by openjpa 2.0 for the use of an unenhanced class
is not as useful as the message issued by the 1.x versions. In 2.0, the
following message is received:
<openjpa-2.0.0-r422266:935683 nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: Attempt to cast instance
"org.apache.sample.entities.b...@97781f" to PersistenceCapable failed. Ensure
that it has been enhanced.
FailedObject: org.apache.sample.entities.b...@97781f
While the same application run using openjpa 1.x gives this message:
<openjpa-1.2.1-r752877:753278 fatal user error>
org.apache.openjpa.persistence.ArgumentException: No metadata was found for
type "class org.apache.sample.entities.Book". The class does not appear in the
list of persistent types: [org.apache.geronimo.sample.entities.Book].
The 2.0 message no longer points to the persistence.xml definition as the
potential source of error. It should give some possible solutions to "Ensure
that is has been enhanced". Perhaps something like "Ensure that the class is
included in the list of persistent types or enhanced as part of the application
build".
