I always drop the tables between my attempts. I have also tried to drop
the whole DB but that doesn't help.
for
@Persistent
@Externalizer("toString")
private URI uri;
the mapping-tool prints out:
"uri" has mapping
strategy "org.apache.openjpa.jdbc.meta.strats.HandlerFieldStrategy"
There are no warning or erros that say that there's something wrong.
Here is my META-INF/persistence.xml :
<persistence xmlns="http://java.sun.com/xml/ns/persistence"; version="1.0">
<persistence-unit name="openjpa" transaction-type="RESOURCE_LOCAL">
<class>domain.JPATest</class>
<properties>
<property name="openjpa.ConnectionURL"
value="jdbc:postgresql://localhost/jpatest"/>
<property name="openjpa.ConnectionDriverName"
value="org.postgresql.Driver"/>
<property name="openjpa.ConnectionUserName" value="postgres"/>
<property name="openjpa.ConnectionPassword" value=""/>
<property name="openjpa.Log" value="DefaultLevel=TRACE, Tool=TRACE"/>
</properties>
</persistence-unit>
</persistence>
Anything else where I could look first?
Thanks
Lukas
