Question

我已经安装了Tomcat v8.0.35，并按照这些步骤（here）对其进行了配置。我已经检查了它并且工作正常：我去了localhost :( myport）并得到了

现在我安装了Eclipse Mars2企业版，New-＆gt;动态Web项目，我没有目标运行时，所以New Runtime-＆gt; Tomcat v8-＆gt;给出了安装文件夹 - ＆gt;完成。现在项目已经创建，但是当我单击服务器选项卡时，它不会显示tomcat。我收到此消息＆＃34;没有可用的服务器。单击此链接以创建服务器＆＃34;但我无法使用tomcat8创建服务器。

当我创建我的eclipse项目时服务器开启

我不知道如何显示文件，所以我只想按ctrl + c，ctrl + v（提前抱歉）。

因此.log文件中的警告和错误如下所示：
