Question

我是WebSphere的新手（主要使用Tomcat），我正在尝试托管一个Struts / Spring / Hibernate网站。该网站应该能够从Oracle数据库中查找数据并显示该信息。

我目前无法让网站运行，这似乎是一个jndi错误。这是错误：

有人建议尝试<jee:jndi-lookup id="dataSource">，我把它搞定了。但它的行为与<bean id="dataSource">完全相同。

Answer 1

这不是正确的方法。请执行以下操作：

在Eclipse中，转到Help > Eclipse Marketplace
搜索ibm liberty，您会发现 - 用于Luna的WebSphere Application Server Liberty Profile Developer工具（或您正在使用的其他Eclipse版本）。安装工具。
安装后，您将能够创建新服务器 - WebSphere Application Server Liberty Profile - 创建它。您尝试使用的Web预览是针对静态文件，而不是Java EE应用程序。
在向导创建服务器中，您可以选择下载服务器运行时，执行此操作。您也可以从wasdev.net手动下载：
- Download Liberty profile in Eclipse
- Download just the Liberty profile runtime
将您的应用程序添加到服务器。在Servers视图中，展开Liberty服务器并双击服务器配置。你将在那里有功能管理器，你可以在那里添加jdbc。
