我将我的应用程序迁移到 Hibernate 5 和 Glassfish 4。部署时，它尝试生成数据库，但出现此错误：

aused by: org.hibernate.tool.schema.spi.SchemaManagementException: Unable to execute schema management to JDBC target [create table banca (id int8 not null, descricao varchar(255), publica boolean not null, primary key (id))]

这是真的，因为数据库中存在表“banca”，但我的 persistence.xml 是：

   <persistence-unit name="myPU" transaction-type="JTA">
    <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
    <jta-data-source>jdbc/myDS</jta-data-source>
    <exclude-unlisted-classes>false</exclude-unlisted-classes>
    <properties>
        <property name="hibernate.show_sql" value="true"/>
        <property name="hibernate.hbm2ddl.auto" value="update"/>
        <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.SunOneJtaPlatform"/>
        <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
    </properties>
</persistence-unit>

[编辑] 正在使用 persistence.xml，在 Glassfish 日志中出现：
