JBoss DataSource配置问题

Question

I am unable to configure datasource in jBoss. Following is configuration in jboss web.xml

<jboss-web>  
<resource-ref>  
    <res-ref-name>jdbc/testDataSource</res-ref-name> <!-- matches web.xml -->  
    <jndi-name>java:jdbc/testDataSource</jndi-name> <!-- matches oracle-ds.xml -->  
    <res-type>javax.sql.DataSource</res-type>  
</resource-ref>  
</jboss-web>

We have created oracle-ds.xml which contains:

<?xml version="1.0" encoding="UTF-8"?>
<datasources>  
  <local-tx-datasource>  
    <jndi-name>jdbc/testDataSource</jndi-name>  
    <connection-url>jdbc:oracle:thin:@11.120.184.77:1521:starsdev</connection-url>  
    <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>  
    <user-name>cmsusr</user-name>  
    <password>cmsusr</password>  
    <min-pool-size>2</min-pool-size>  
    <max-pool-size>20</max-pool-size>  
    <idle-timeout-minutes>5</idle-timeout-minutes>  
    <track-statements/>  
    <metadata>  
      <type-mapping>Oracle10g</type-mapping>  
    </metadata>  
  </local-tx-datasource>  
</datasources>

I have created one servlet which contains following code in service method:

Context initialContext = new InitialContext();  
Context envContext = (Context) initialContext.lookup( "java:comp/env" );  
DataSource ds = (DataSource) envContext.lookup( "jdbc/testDataSource" );
PrintWriter pw = response.getWriter();
pw.print(ds);

When I'm running my servlet it is showing following error:

[STDOUT] javax.naming.NameNotFoundException: jdbc not bound

Do it in a single lookup. There's no need to use two Contexts here.

 Context initialContext = new InitialContext(); 
 DataSource ds = (DataSource) initialContext.lookup("java:comp/env/jdbc/testDataSource");
