eclipselink - EclipseLink不会生成表

Question

我定义了一些实体，现在想生成表。

我使用Eclipselink 2.5(JPA 2.1)和Glassfish 4.0，我的程序使用JKD7。

当我构建应用程序时，会显示以下消息:

warning: Supported source version 'RELEASE_6' from annotation processor 'org.eclipse.persistence.internal.jpa.modelgen.CanonicalModelProcessor' less than -source '1.7'

Note: Creating static metadata factory ...
Note: Optional file was not found: META-INF/orm.xml continuing with generation.
Note: Optional file was not found: META-INF/eclipselink-orm.xml continuing with generation.
Note: Optional file was not found: META-INF/orm.xml continuing with generation.
Note: Optional file was not found: META-INF/eclipselink-orm.xml continuing with generation.

我现在不知道该怎么办...

我拥有最新的EclipseLink版本

最新版本的glassfish

jkd 7

只是标准的derby数据库(随glassfish 4.0一起提供)

我该如何解决？

<properties>
  <property name="eclipselink.ddl-generation" value="drop-and-create-tables"/>
  <property name="eclipselink.ddl-generation.output-mode" value="database"/>
</properties>

只需将这些行放在persistence.xml中:

<property name="eclipselink.ddl-generation" value="create-tables" />
<property name="eclipselink.ddl-generation.output-mode" value="database" />
<property name="eclipselink.ddl-generation-mode" value="ddl_database_generation" />
