我正在尝试在JDBC connection pool中实施JBoss EAP 6.4。我使用JBoss EAP 6.1+ adapter IDE中的Eclipse Luna和Jboss EAP management console来管理此服务器。
我的应用程序使用的数据库是Oracle 11g SE。我正在使用的JDBC jar版本是Oracle Database 12c Release 1 (12.1.0.1) JDBC Driver
以下是我遵循的步骤：
将JDBC jar部署为独立应用程序。为此，我将jar放在jboss-eap-6.4\standalone\deployments目录中。然后我从eclipse重新启动服务器，我可以看到服务器自动将JDBC jar识别为符合Type 4的驱动程序。
然后，我使用JBoss EAP管理控制台UI创建并配置了数据源。我能够使用UI成功测试连接。以下是用户在standalone.xml目录中的jboss-eap-6.4\standalone\configuration文件中创建的条目
<datasource jta="true" jndi-name="java:/MyWebServiceOracleDs" pool-name="MyWebService" enabled="true" use-ccm="true" statistics-enabled="true">

import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;
InitialContext context = null;
DataSource dataSource = null;
Connection conn = null;
try
{
// Create a Database Connection
context = new InitialContext();
dataSource = (DataSource) context.lookup("java:/MyWebServiceOracleDs");
conn = dataSource.getConnection();
一旦我在服务器上运行更新的代码并运行我的单元测试，我就会得到以下异常：
javax.naming.NamingException: Lookup failed for 'java:/MyWebServiceOracleDs' in SerialContext[myEnv={java.naming.factory.initial=com.sun.enterprise.naming.impl.SerialInitContextFactory, java.naming.factory.url.pkgs=com.sun.enterprise.naming, java.naming.factory.state=com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl} [Root exception is javax.naming.NameNotFoundException: No object bound for java:/MyWebServiceOracleDs [Root exception is java.lang.NullPointerException]]

似乎我在查找服务器上创建的数据源时遇到问题。我在代码中使用其确切的JNDI名称。我可以直接在我的代码中引用JNDI资源，还是必须先在我的应用程序中在某个XML配置文件中定义它。
只是一些背景知识，我的应用程序是使用JAX-B annotations创建的Web服务。我已将其创建为Dynamic Web Project
Eclipse工作区。
我正在尝试了解导致此问题的原因以及我如何解决此问题。
