eclipse中安装tomcat插件重启后工具栏不显示tomcat图标问题以及tomcat中加载工程的配置

1.下载tomcat 插件

首先下载 对应 eclipse 版本的 tomcat 插件版本，(这里要注意: Tomcat 插件是Tomcat 插件，Tomcat 是 Tomcat, 两者不能混淆！)，下载地址：http://www.eclipsetotale.com/tomcatPlugin.html

2.安装方法（见所下插件安装包中的readme文件，这里是最新的插件3.3.0）

Installation

• This plugin does not contain Tomcat.
  (Download and install Tomcat before using it)
• Download tomcatPluginV??.zip
• Unzip it in <eclipse_home>/plugins
• Plugin activation for Eclipse 3.x :
  - launch eclipse once using this option : -clean
  - if Tomcat icons are not shown in toolbar : select menu 'Window>Customize Perspective...>Commands', and check 'Tomcat' in 'Available command groups'
  
• Set Tomcat version and Tomcat home : Workbench -> Preferences, select Tomcat and set Tomcat version and Tomcat home
  (Tomcat version and Tomcat home are the only required fields, other settings are there for advanced configuration).
  
• This plugin launches Tomcat using the default JRE checked in Eclipe preferences window.
  To set a JDK as default JRE for Eclipse open the preference window : Window -> Preferences -> Java -> Installed JREs.
  This JRE must be a JDK (This is a Tomcat prerequisite).
  
• The plugin sets itself Tomcat classpath and bootclasspath. Use Preferences -> Tomcat ->JVM Settings, only if you need specific settings.

      将得到的压缩包解压，放入 eclipse 的 plugins 目录中重启 eclipse, Tomcat 插件安装成功！如此时eclipse工具栏中的tomcat图标仍未显示，可在cmd窗口，进入安装eclipse的文件夹，然后使用 “eclipse.exe -clean”命令启动eclipse重新加载工具栏即可。如下图：

3.修改tomcat配置文件（注：以下为tomcat配置与上文无关）

        修改tomcat安装文件中conf文件夹下的server.xml文件：

1.添加 URIEncoding="utf-8"/> 防止中文乱码。

  <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" URIEncoding="utf-8"/>

2.后面添加项目路径配置：

<Context path="/econtract" docBase="G:\workspace\econtract\WebContent" reloadable="true" />
