Subject [jira] [Created] (OPENJPA-2341) OpenJPA ignores custom field strategies globally defined in persistence.xml
Date Wed, 27 Feb 2013 16:25:12 GMT
Michael Rüegg created OPENJPA-2341:
--------------------------------------

             Summary: OpenJPA ignores custom field strategies globally defined in persistence.xml
                 Key: OPENJPA-2341
                 URL: https://issues.apache.org/jira/browse/OPENJPA-2341
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 2.2.0
            Reporter: Michael Rüegg


I use a custom field strategy value handler (a class that extends org.apache.openjpa.jdbc.meta.strats.AbstractValueHandler)
for my entities that make use of joda time fields:

@Entity
public class MyEntity {
  org.joda.time.LocalDateTime creationDate;
}

When I use the inline strategy annotation (@Strategy("com.xyz.LocalDateValueHandler")), everything
works as expected and my LocalDateTime field 'creationDate' gets mapped to an SQL timestamp.
However, if I reference my value handler globally in the persistence.xml file, then OpenJPA
is not able to find the value handler (i.e., it is never called), which results in a blob
column type for 'creationDate'. Here's the corresponding snippet from my persistence.xml:

<property name="openjpa.jdbc.MappingDefaults" value="FieldStrategies='org.joda.time.LocalDateTime=com.xyz.LocalDateValueHandler"/>

Note that if I use a mapping from a standard JDK class like java.lang.String to my value handler,
then my handler is called as expected. Is this issue somehow related to #OPENJPA-758? Note
that I use Derby as my database.

Any help would be much appreciated.
