無法連接到在Eclipse中啟動的Tomcat 6實例

Question

我正在運行Tomcat 6.0.36。 在控制台中獨立運行時，服務器運行良好。 我還配置了Eclipse使其能夠運行，以便可以調試。 配置成功完成，沒有錯誤。 但是，當我運行服務器時，無法在瀏覽器中訪問http://localhost:8080 （獲取404）。

這是Eclipse跟蹤：

控制台跟蹤如下：

我注意到的第一件事是Eclipse跟蹤的第二行：

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蹤報告

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

APR確實是問題所在嗎？ 如果是，如何解決它，以便Eclipse服務器使用與控制台相同的庫？

Answer 1

APR不是問題。 當您從eclipse啟動tomcat時，eclipse會“覆蓋”某些服務器配置（您也可以直接從eclipse更改程序包/項目瀏覽器下“服務器”項目中的配置文件）。

如果要訪問tomcat的根目錄，則可以雙擊服務器（在刪除所有項目后），然后選擇表示Takes control of Tomcat installation的配置。 然后保存，重新啟動服務器，您將可以在未部署任何應用程序的情況下訪問localhost 。
