Tomcat (TomEE)/7.0.62 (1.7.2) XML 配置文件最佳实践
Tomcat (TomEE)/7.0.62 (1.7.2) XML Configuration Files best practices
我已经在 C:// 中解压缩了一个二进制分发包，但是我很难让 JDBC 和 JDNI 工作...它没有从我的数据库中获取数据所以我假设我没有正确的文件配置。
Strangely, i'm able to see data with <c:forEach var="cartItem" items="${cart.items}" varStatus="iter"/>but no data displays with <c:forEach var="product" items="${categoryProducts}" varStatus="iter"/>

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。
context.xml您还有更多选择，但我建议您使用 Web 应用程序的 META-INF 目录。
如果您需要配置方面的帮助，则需要提供更多信息，包括：
- 完整Tomcat版本
- 您added/edited
的配置文件
- 您放置 WAR 文件/分解目录的位置
- 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
提供以上信息后更新
数据源配置错误。 Tomcat 不支持
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
我已经在 C:// 中解压缩了一个二进制分发包，但是我很难让 JDBC 和 JDNI 工作...它没有从我的数据库中获取数据所以我假设我没有正确的文件配置。

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。
context.xml您还有更多选择，但我建议您使用 Web 应用程序的 META-INF 目录。
如果您需要配置方面的帮助，则需要提供更多信息，包括：
- 完整Tomcat版本
- 您added/edited 的配置文件
- 您放置 WAR 文件/分解目录的位置
- 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
提供以上信息后更新
数据源配置错误。 Tomcat 不支持
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
