使用Hibernate 4.0與Tomcat 7和JSF 2.0時的JndiException

Question

應用程序部署后，當方法執行時，我得到以下錯誤。

Caused by: org.hibernate.service.jndi.JndiException: Unable to lookup JNDI name [java:comp/env/JSF_HIBER/ORACLE]

的context.xml

<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" />

的hibernate.cfg.xml

<?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">

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.datasource">java:comp/env/JSF_HIBER/ORACLE</property>
        <property name="hibernate.bytecode.use_reflection_optimizer">false</property>
        <property name="dialect">org.hibernate.dialect.Oracle10gDialect</property>
        <property name="hibernate.connection.pool_size">10</property>
        <property name="show_sql">true</property>
        <property name="hibernate.current_session_context_class">thread</property>
    <mapping class="com.entity.User"/>
    </session-factory>
</hibernate-configuration>

在web.xml

<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>

我不知道為什么會收到此錯誤，請幫助我...

Answer 1

您必須在hibernate.cfg.xml文件的“ java：”和“ comp”之間添加斜杠：

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

它可能會解決問題

Answer 2

您可能需要在META-INF/context.xml執行以下操作，以將全局JNDI資源鏈接到特定於應用程序的資源：

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

它將全局數據源JSF_HIBER/ORACLE鏈接到本地​​的java:comp/env/JSF_HIBER/ORACLE 。

編輯：

如果您不想創建應用程序級別的鏈接，則可以使用全局URL：

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