问题一：

报错:

2012-1-17 23:55:06 org.apache.catalina.core.StandardContext start
严重: Context [/strutsq] startup failed due to previous errors

分析：

前三个Caused by为：Caused by: Unable to load bean: type: class:org.apache.struts2.views.freemarker.FreemarkerManager - bean - jar:file:/F:/Genuitec/Workspaces/MyEclipse7.5/strutsq/WebRoot/WEB-INF/lib/struts2-core-2.3.1.1.jar!/struts-default.xml:54:89
 Caused by: java.lang.NoClassDefFoundError: freemarker/template/TemplateException
Caused by: java.lang.ClassNotFoundException: freemarker.template.TemplateException
 都含有“feemarker”，故缺少freemarker.jar，将其导入即可。

原因：

myeclipse7.5建立jsp文件时自动生成:

<%@ taglib uri="" prefix="h" %>
<%@ taglib uri="" prefix="f" %>

将这两行删除即可！

 

 

问题三：

还遇到了一个tomcat报的异常，显示跟commons-lang有关。

尝试解决：将lib里的commons-lang.jar更换成commons-lang2.1.3.jar，并将myeclipse重启，问题解决!想研究怎么回事，又将commons-lang2.1.3.jar还原成commoon-lang.jar，但又没有报错，一切正常！郁闷！
