首先安装NetBeans,jdk1.7 glassfish3.1.1.2 安装完成之后配置数据源
首先配置Jdbc连接池-->新建-->输入名字和资源类型-->可将其余属性删除只添加 url user password
完成之后可以ping一下测试是否成功
配置JDBC资源-->新建-->名字和选择连接池
简单的数据源便配置完成
netbeans -->新建项目-->J2EE-->EJB模块(Ejb项目建立成功)
在配置文件(setup)添加数据源配置文件 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="uappPU" transaction-type="JTA"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <jta-data-source>jdbc/uapp</jta-data-source> <!-- 此名为glassfish数据源的jdbc名字相同--> <exclude-unlisted-classes>false</exclude-unlisted-classes> <properties> <property name="hibernate.hbm2ddl.auto" value="update"/> <property name="hibernate.show_sql" value="true"/> <property name="hibernate.format_sql" value="true"/> </properties> </persistence-unit> </persistence>
