Tomcat (TomEE)/7.0.62 (1.7.2) XML 配置文件最佳实践

Question

我在C:// 中解压缩了一个二进制发行版，但我很难让JDBC 和JDNI 正常工作...它没有从我的数据库中获取数据，所以我认为我没有合适的文件的配置。

奇怪的是，<c:forEach var="cartItem" items="${cart.items}" varStatus="iter"/> 可以看到数据，但<c:forEach var="product" items="${categoryProducts}" varStatus="iter"/> 没有数据显示

第二次编辑

我在 $CATALINA_HOME/lib 中添加了这些 jar：

• javaee-api-6.0-6.jar
• javax.servlet.jsp.jstl-1.2.1.jar

没有 WAR 文件被分解，因为目前我在 Netbeans 8.0.2 中进行本地开发，但如果它与部署相同，服务器会自动在Web Applications 下创建一个副本（如果相同，请原谅我的无知） .

Answer 1

resource.xml 不是 Apache Tomcat 配置文件。 persistence.xml 不是 Apache Tomcat 配置文件。

server.xml 必须位于 conf 目录中。

你有更多的 context.xml 选项，但我推荐你的 web 应用程序的 META-INF 目录。

如果您需要有关配置的帮助，则需要提供更多信息，包括：

• 完整的 Tomcat 版本
• 您添加/编辑的配置文件
• 您放置 WAR 文件/展开目录的位置
• 您添加的任何其他 JAR 以及放置它们的位置
• 日志中的任何错误消息

提供上述信息后更新

DataSource 的配置错误。 Tomcat 不支持 也不支持 标签。如果 TomEE 提供了对这些的支持，那么我无能为力（我只知道 Tomcat）。在 Tomcat 中，我希望看到一个 元素。

对于 Tomcat（我怀疑是 TomEE），您需要在 $CATALINA_BASE/lib 中提供 MySQL JDBC 驱动程序 JAR。
