无法创建资源实例。 javax.naming

Question

试图使用tomcat池来连接数据库。

这里是我的代码：

的web.xml

<resource-ref> 
    <description>Resource pour le pool de connexion vers tomcat</description> 
    <res-ref-name>jdbc/pool</res-ref-name> 
    <res-type>javax.sql.DataSource</res-type> 
    <res-auth>Container</res-auth> 
</resource-ref> 

的context.xml：

DataSource ds; 

//récupération de la source de donnée 
Context initCtx = new InitialContext(); 
ds = (DataSource) initCtx.lookup("java:comp/env/jdbc/pool"); 

conn = ds.getConnection(); 

我：

<Context antiJARLocking="true" path="/CompteBancaire"> 
    <Resource name="jdbc/pool" auth="container" type="javax.sql.Datasource"> 
     <ResourceParams name="jdbc/pool"> 
      <parameter> 
       <name>username</name> 
       <value>marc</value> 
      </parameter> 
      <parameter> 
       <name>password</name> 
       <name>marc</name> 
      </parameter> 
      <parameter> 
       <name>driverClassName</name> 
       <value>oracle.jdbc.driver.OracleDriver</value> 
      </parameter> 
      <parameter> 
     <name>url</name> 
     <value>jdbc:oracle:thin:@localhost:1521:xe</value> 
      </parameter> 
      <parameter> 
       <name>factory</name> 
       <value>org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory</value> 
      </parameter> 
     </ResourceParams> 
    </Resource> 
</Context> 

在我的DAO类的构造函数

试图寻找^ an的豁免d创建数据源：
