了解如何配置WAS或OpenJPA以使用Container Managed Authentication与Container Managed Entity Manager。
尝试通过在JNDI中注册的JDBC数据源以persistence.xml中定义的“jdbc / DB2”(它指的是Oracle)来访问Oracle数据库。
的persistence.xml
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0"
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_1_0.xsd">
<persistence-unit name="DB2AccountUnit" transaction-type="JTA">
<jta-data-source>jdbc/DB2</jta-data-source>
<class>sample.jpa.Db2account</class>
<properties>
<property name="openjpa.Log" value="File=C:/opt/openjpa/org.apache.openjpa.log, DefaultLevel=INFO, Runtime=TRACE, Tool=INFO, SQL=TRACE, JDBC=TRACE" />
<!-- Without these properties, the error is caused.
<property name="openjpa.ConnectionUserName" value="User" />
<property name="openjpa.ConnectionPassword" value="Password" />
-->
</properties>
</persistence-unit>
</persistence>
但是,当访问持久性单元的容器管理实体管理器时,会抛出ORA-01017无效的usrname / password。如果在persistence.xml中指定了ConnectionUserName / ConnectionPassword,则会解决错误。

使用实体管理器的Servlet
原文来自IBM developerWorks文章。在servlet实例变量中注入实体管理器不是多线程安全的,而是为了测试。
@WebServlet("/CreateAccount")
public class CreateAccount extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet {

请帮助理解为什么不使用JAAS以及如何配置WAS或JPA来使用它。

尝试了IBM redbook WebSphere Application Server for Developers V7的JPA示例。部署了应用程序版本2并得到了同样的错误。
答案 0 :(得分:1)
在persistence.xml
中您必须使用资源引用,例如java:comp/env/jdbc/DB2Ref
而不是全局JNDI名称。您必须在部署描述符中或通过使用JPA的模块/组件中名称为jdbc/DB2Ref
的注释定义资源引用。
如果要在persistnece.xml中使用全局JNDI名称,则必须设置Component-managed authentication alias
而不是Container-managed
,仅当通过引用访问数据源时才使用容器。

基于@Gas的回答,做了一些实验。

JPA 2.0规范说它是要指定的数据源的全局JNDI名称。 IBM WAS知识中心表示ENC名称是WAS扩展名。
我认为由于容器管理身份验证是通过资源引用而EJB3 @Resource(name)是ENC名称资源引用java:comp / env /,因此使用JPA的容器身份验证是probaby供应商特定的。

8.2.1.5 jta-data-source,non-jta-data-source
在Java EE环境中,jta-data-source和non-jta-data-source元素用于指定JTA和/或非JTA数据源的 全局JNDI名称 供持久性提供程序使用。如果两者都未指定,则部署者必须在部署时指定JTA数据源或
IBM WAS 8.5.5 Associating persistence providers and data sources
用于WebSphere Application Server解决方案的JPA 扩展了JNDI数据源实现,以允许您引用组件名称空间中的数据源。在EJB或Web模块部署描述符文件中,这是元素。
您可以使用java:comp / env /为数据源添加前缀,以便应用程序使用本地JNDI名称间接引用数据源。
