Re: How to set the type of the DB-field using @Externalizer
I'm trying to use the @Externalizer annotation but have problems with the resulting type of the DB-field - it's always a byte-array. You shouldn't need the @Type annotation -- the type will be inferred from the return type of the externalizer method. Are you dropping the database table in between attempts? It's possible that if your first attempt resulted in a byte array column because of some misconfiguration, OpenJPA will think it is supposed to reuse that column on subsequent mapping attempts, because technically it can fit anything in a byte-array column.

Re: How to set the type of the DB-field using @Externalizer
I can't reproduce this. When I leave out the @Persistent annotation on the field or replace it with @Basic, I do indeed end up with a binary column. But if I correctly include the @Persistent annotation along with the @Externalizer, I get a varchar column. Can you narrow down your entity to the smallest possible class that exhibits the problem and post it to the list so we can try to reproduce the error?

Finally it works. After I've reduced the project to one class with
one field and using derby as DB the problem was still the same. So
I found the problem in the ant-file that did the enhance and mapping
tasks.
But I don't understand the problem - maybe you have an explaination.
The problem was the entry 'pathelement path=${java.class.path}/' in
the element classpath. After I removed this line in both tasks it worked.
Here is the ant-file:
---
project name=openjpa-test default=refresh
descriptionJPA test/description
target name=enhance
taskdef name=openjpac
classname=org.apache.openjpa.ant.PCEnhancerTask/
openjpac
config propertiesFile=META-INF/persistence.xml/
fileset dir=${basedir}
include name=domain/*.java /
/fileset
classpath
pathelement location=${basedir}/
pathelement path=${java.class.path}/
/classpath
/openjpac
/target
target name=refresh depends=enhance
taskdef name=mappingtool
classname=org.apache.openjpa.jdbc.ant.MappingToolTask/
mappingtool action=buildSchema
config propertiesFile=META-INF/persistence.xml/
fileset dir=${basedir}
include name=domain/*.java /
/fileset
classpath
pathelement location=${basedir}//
pathelement path=${java.class.path}/
/classpath
/mappingtool
/target
/project
---
my classpath is:
lib/commons-collections-3.2.jar
lib/commons-lang-2.1.jar
lib/commons-logging-1.0.4.jar
lib/commons-pool-1.3.jar
lib/derby-10.2.2.0.jar

lib/openjpa-all-0.9.7-incubating-SNAPSHOT.jar
lib/postgresql-8.1-408.jdbc3.jar

Thanks for your help
