导入项目发现 Target runtime Apache Tomcat v7.0 is not defined.

运行时没有找到tomcat v7.0

Eclipse

右键--》properties--》targeted runtime,把原项目的tomcat去掉勾选,换上自己的Tomcat

myEclipse

在工程目录下的.settings文件夹里，打开org.eclipse.wst.common.project.facet.core.xml文件，其内容是：

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
    <runtime name="Tomcat v7.0"/>
  <fixed facet="java"/>
  <fixed facet="jst.web"/>
  <fixed facet="wst.jsdt.web"/>
  <installed facet="java" version="1.6"/>
  <installed facet="jst.web" version="3.0"/>
  <installed facet="wst.jsdt.web" version="1.0"/>
</faceted-project>

删除第一句话后是

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>

  <fixed facet="java"/>
  <fixed facet="jst.web"/>
  <fixed facet="wst.jsdt.web"/>
  <installed facet="java" version="1.6"/>
  <installed facet="jst.web" version="3.0"/>
  <installed facet="wst.jsdt.web" version="1.0"/>
</faceted-project>

保存，刷新!
