我使用Netbeans和GlassFish开发了一个带JPA的JSF应用程序。它在Netbeans环境中运行良好。现在我想部署一个具有不同数据库设置的远程GlassFish服务器。有没有什么方法可以在数据库首次部署到服务器时提供数据库设置并保存后的设置？ 我有一个persistence.xml文件，但是数据库设置在glassfish-resources.xml文件中。
的persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
<persistence-unit name="HOPU" transaction-type="JTA">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<jta-data-source>dsHiLap2</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
<property name="eclipselink.ddl-generation" value="create-tables"/>
</properties>
</persistence-unit>
的glassfish-resources.xml中
<?xml version="1.0" encoding="UTF-8"?>

答案 0 :(得分：2)
您需要使用GlassFish部署计划为远程GlassFish服务器配置不同的连接池设置，因为glassfish-resources.xml定义了应用程序范围的资源。应用程序范围的连接池仅在应用程序部署期间创建。请参阅To Deploy an Application or Module by Using a Deployment Plan。基本上，您在deploymentplan.jar中提供了glassfish-resources.xml的远程服务器版本（遵循module-name.gf-dd-name命名约定）。
另一个选择是不使用应用程序作用域资源。您可以通过GlassFish管理控制台定义连接池/数据源。
