struts-2.1.6的配置错误一例

用spring2.5+struts2+ibatis2搭建了一个系统，本来只想做个小测试的。谁知道，一运行就抛错：

2009-5-27 17:09:03 org.apache.catalina.core.StandardContext filterStart

 怎么会冒出个freemarker啊？真奇怪，我没有用到它啊。

没办法，只好找来freemarker-2.3.13.jar加入之后，没有报错了。^_^

 

很多人都是因为jar缺少或者多余造成了系统的出错。正常使用struts2.1.6，至少需要如下6 个jar包：

struts2-core-2.1.6.jar
freemarker-2.3.13.jar
commons-logging-1.0.4.jar
ognl-2.6.11.jar
xwork-2.1.2.jar
commons-fileupload-1.2.1.jar

还有时候会有莫名其妙的报错。有时候重新建立一遍工程就好了。

希望对大家有帮助。
