Target runtime Apache Tomcat v7.0 is not defined.

 

问题描述与解决

在problems中显示错误是：Target runtime Apache Tomcat 6.0 is not defined. 在网上查了一下终于找到解决方法。方法是：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：

<?xmlversion="1.0"encoding="UTF-8"?> 
<faceted-project> 
<runtimename="Apache Tomcat v6.0"/> 
<fixedfacet="jst.web"/> 
<fixedfacet="jst.java"/> 
<installedfacet="jst.java"version="6.0"/> 
<installedfacet="jst.web"version="2.5"/> 
<installedfacet="wst.jsdt.web"version="1.0"/> 
</faceted-project>

 

将其改为

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