尝试使用Glassfish4服务器从Derby切换到Postgresql失败后，我想切换回我以前的基于Derby的Web应用程序。但是当我尝试部署我的应用程序时，出现以下错误：

这是我的persistence.xml文件

这是我之前使用的文件，因为我使用git，然后检查了我在后者中所做的所有修改。这可能是个问题？
更新
我想我找到了缺少属性databaseName的位置。它是Glassfish配置的domain.xml文件，不在git下。这是jdbc-connection-pool部分
<jdbc-connection-pool is-isolation-level-guaranteed="false" datasource-classname="org.apache.derby.jdbc.ClientDataSource" res-type="javax.sql.DataSource" name="DerbyPool">
<property name="eclipselink.target-database" value="DERBY" />
<property name="eclipselink.jdbc.driver" value="org.apache.derby.jdbc.ClientDriver" />
<property name="eclipselink.jdbc.url"
value="jdbc:derby://localhost:1527/tiebreak;create=true" />
<property name="eclipselink.jdbc.user" value="APP" />
<property name="eclipselink.jdbc.password" value="APP" />
<property name="eclipselink.ddl-generation" value="drop-and-create-tables" />
<property name="eclipselink.logging.level" value="INFO" />
<property name="eclipselink.deploy-on-startup" value="true" />
</jdbc-connection-pool>
现在的问题是要了解此属性应采用的值。我没有在这里和那里找到任何提示。
更新2
我试图插入
具有以下结果
remote failure: Error occurred during deployment: Exception while preparing the app : Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Error in allocating a connection. Cause: Connection could not be allocated because: The connection was refused because the database sun-appserv-samples was not fou
第二
答案 0 :(得分：1)
我发现了我的问题。 sun-appserv-samples目录不在工作空间/下，而是在主要的空间目录下。处理项目一下的整个目录（并重新启动glassfish以避免安全问题）解决了我的问题
