I'm working on simple application with Spring, JPA (Hibernate) and Apache Derby. All my entyties are definied with annotations. Because I'm using maven dependency management I would like to create the ddl for Apache Derby with the hbm2ddl plugin. Basically no problem. But I've realised that no unique constraints are created. Regardless if I define it with the @UniqueConstraint or the @NaturalId annotation. Even properties with the @NotNull annotation are not null. But all the 'create table'-statements are created correctly. I'm using the following configuration for the hbm2ddl plugin:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>hibernate3-maven-plugin</artifactId>
<version>2.2</version>
<dependencies>
...
</dependencies>
<executions>
<execution>
<phase>compile</phase>
<goals>
<goal>hbm2ddl</goal>
</goals>
</execution>
</executions>
<configuration>
<components>
<component>

<outputfilename>db-schema.sql</outputfilename>
<propertyfile>hbm2ddl.properties</propertyfile>

</configuration>
</plugin>
