问题：

使用JNDI连接到JBoss7中创建的数据源时，eclipse中的javax.naming.NameNotFoundException

田冥夜
2023-03-14

我对J2EE是新手。我试图连接到使用JNDI在jboss AS 7中创建的数据源。

我使用Jboss作为7独立服务器来部署我的项目newdb.war。我已经在Jboss AS 7中创建了休闲数据源java：Jboss/datasources/oracleds（这是我的JNDI名称），并成功连接到Oracle数据库。

我正在使用oracle数据库存储我的sql表。

我在Eclipse中得到了休耕错误消息。但我在Propmpt命令中得到了成功的消息。我在eclipse中创建了Dynamic web project来执行所有这些任务。我不确定为我的任务创建哪种类型的项目。如果我错了请纠正我。

如果有人帮助走出这个错误，这将是很大的帮助。

  • 您的context.xml文件将被忽略，因为它是Tomcat配置文件，并且您正在运行JBoss as；
  • 您的web.xml格式错误，我很惊讶它没有导致部署错误--至少它可能被忽略；
  • 我相信您的代码可以从命令行运行，因为部署顺序会发生微妙的变化。当您从Eclipse运行时，您的webapp是在您的数据源之前被初始化的，这可能是因为Eclipse的显式部署指令。

通常，JBoss AS可以通过分析注释或部署描述符来确定正确的部署顺序。但是，您没有任何可用的形式。

由于这是一个兼容JavaEE6的服务器，您应该不需要显式的JNDI查找。请尝试以下操作：
