以下是在GG搜索到的。http://stackoverflow.com/questions/75786/eclipse-how-can-i-change-a-project-facet-from-tomcat-6-to-tomcat-5-5

首先在硬盤下找到  \項目名\.setting\文件夾下的   org.eclipse.wst.common.project.facet.core.xml  xml文件。

<pre name=“code” class=“html”><?xml version=“1.0” encoding=“UTF-8”?>
<faceted-project>
  <fixed facet=“wst.jsdt.web”/>
  <installed facet=“jst.web” version=“3.0”/>
  <installed facet=“wst.jsdt.web” version=“1.0”/>
  <installed facet=“java” version=“1.7”/>
</faceted-project>

<pre name="code" class="html"><?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
  <fixed facet="wst.jsdt.web"/>
  <installed facet="jst.web" version="3.0"/>
  <installed facet="wst.jsdt.web" version="1.0"/>
  <installed facet="java" version="1.7"/>
</faceted-project>

將jst.web，的version改成2.5.

然後在eclipse裏右鍵該工程–maven–updateProject即可。
