我创建了一个使用derby数据库的jar文件（sms.jar），我将其包含在我的一个项目（CommunicationProject）中，我使用wildfly-8.0.0.Final来部署我的项目（CommunicationProject），以及hibernate我在sms.jar中使用derby而我在CommunicationProject中使用mysql但我有以下问题：
问题1。 我总是得到这个日志我真的不知道这只是信息还是错误

13:11:00,226 INFO [org.hibernate.tool.hbm2ddl.SchemaExport] (default task-9) HHH000230: Schema export complete
我检查过德比港是否打开或关闭但是我发现没有打开端口号1527，为了克服这个问题，我需要重新启动不正确的野生动物。
问题3。 我已经设置了hibernate confiugration（在jar文件中）
＆LT; property name="hbm2ddl.auto">create</property>
如果我把它改成
<property name="hbm2ddl.auto">update</property>
我需要创建数据库manaully，我的要求是只在主应用程序的第一个部署时间创建数据库（sms.jar文件应该创建数据库）（使用jar文件的应用程序是CommunicationProject）并保留smsDB数据库中的数据，即使应用程序（CommunicationProject）部署为第二，第三......等时间。或者即使wildfly服务器重新启动。
