在部署应用程序之后，当执行方法时，我遇到错误。

context.xml中

<Resource name="JSF_HIBER/ORACLE" auth="Container"
    type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000"
    username="****" password="**** driverClassName="oracle.jdbc.OracleDriver"
    url="jdbc:oracle:thin:@99.99.999.999:1521:xe" />

hibernate.cfg.xml中

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

    <mapping class="com.entity.User"/>
    </session-factory>
</hibernate-configuration>

Web.xml中

<resource-ref>
        <description>JSF_HIBER</description>
        <res-ref-name>JSF_HIBER/ORACLE</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
    </resource-ref>

我不知道为什么我会收到此错误，请帮助我......

Answer 1

您必须在hibernate.cfg.xml文件中的“java：”和“comp”之间添加斜杠：

<property name="hibernate.connection.datasource">java:/comp/env/JSF_HIBER/ORACLE</property>

它可能会解决问题

Answer 2

您可能需要META-INF/context.xml中的以下内容将全局JNDI资源链接到特定于应用程序的资源：

<Context>
  <ResourceLink name="JSF_HIBER/ORACLE"
            global="JSF_HIBER/ORACLE"
            type="javax.sql.DataSource"
</Context>

将您的全球数据源JSF_HIBER/ORACLE与您当地的数据源java:comp/env/JSF_HIBER/ORACLE相关联。

编辑：

如果您不想创建应用程序级别链接，则可以改为使用全局URL：

<property name="hibernate.connection.datasource">JSF_HIBER/ORACLE</property>

使用Hibernate 4.0与Tomcat 7和JSF 2.0时的JndiException
