A full JDK must be specified myeclipse安装JRE（JDK）烦恼

最近在整Myeclipse 4.0的东西。在配置tomcat 的时候费了大劲了。老是报下边的错误
to launch an application server,a full jdk(not just a jre) must be specified.
if the selected jre is actually part of a full jdk,please update its configuration to point to the jdk installation root directory,not to its included jre subdirectory.
不过最终敲定了。
  选择的jdk 就是你盘符下jdk 的安装目录不是jre的。名字无所谓。
  JRE type：Standard VM
  JRE name：随便
  JRE home directory:%JAVA_HOME%
  哦了。
