java – 上下文是只读的

前端之家收集整理的这篇文章主要介绍了java – 上下文是只读的前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

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WEB-LIB / web.xml的开头

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

我可以将Context的只读属性设置为“true”吗?谢谢! 原文链接:https://www.f2er.com/spring/432686.html
