无法连接到在Eclipse中启动的Tomcat 6实例

Question

我正在运行Tomcat 6.0.36。 在控制台中独立运行时，服务器运行良好。 我还配置了Eclipse使其能够运行，以便可以调试。 配置成功完成，没有错误。 但是，当我运行服务器时，无法在浏览器中访问http://localhost:8080 （获取404）。

这是Eclipse跟踪：

控制台跟踪如下：

我注意到的第一件事是Eclipse跟踪的第二行：

INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path

而功能良好的控制台跟踪报告

INFO: Loaded APR based Apache Tomcat Native library 1.1.23 using APR version 1.4.6.

APR确实是问题所在吗？ 如果是，如何解决它，以便Eclipse服务器使用与控制台相同的库？

Answer 1

APR不是问题。 当您从eclipse启动tomcat时，eclipse会“覆盖”某些服务器配置（您也可以直接从eclipse更改程序包/项目浏览器下“服务器”项目中的配置文件）。

如果要访问tomcat的根目录，则可以双击服务器（在删除所有项目后），然后选择表示Takes control of Tomcat installation的配置。 然后保存，重新启动服务器，您将可以在未部署任何应用程序的情况下访问localhost 。
