Helo大师,我必须动态创建一个JNDI数据源,我试着用一个叫做SetupApplicationListener的监听器来做.这是开始WEB-LIB/web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee">

    <display-name>pri-web</display-name>

    <!-- Listeners -->
    <listener>
        <listener-class>org.apache.myfaces.webapp.StartupServletContextListener</listener-class>
    </listener>
    <listener>
        <listener-class>myapp.SetupApplicationListener</listener-class>
    </listener>

听众的代码:

public class SetupApplicationListener implements ServletContextListener {

    public static Log LOG = null;

    public void contextInitialized(ServletContextEvent ctx){
        try {            
            createOracleDataSource();
.....
        }
    }

    private void createOracleDataSource() throws SQLException, NamingException {
        OracleDataSource ds = new OracleDataSource();
        ds.setDriverType(...);
        ds.setServerName(...);
        ds.setPortNumber(...);
        ds.setDatabaseName(...);
        ds.setUser(...);
        ds.setPassword(...);

        new InitialContext().bind("java:comp/env/jdbc/myDS", ds);
    }

.....
}

并且有错误:

[ERROR] 29/01/2013 09:44:50,517 (SetupApplicationListener.java:86) -> Error
javax.naming.NamingException: Context is read only
