最近玩用重新用了下ssh，跟以前相比无非是版本上有些不一样，也就stuts2和struts1有些不一样其他的都差不多。
进入正题：
工程正常运行以后，出现很多诸如Could not find property [templateDir]

等警告信息。
搜了一下，都问的人不少，解决方案几乎没有，于是乎来到apache官网搜了一把，貌似有提到这个。
参考地址：http://cwiki.apache.org/S2WIKI/troubleshooting-guide-migrating-from-struts-20x-to-21x.html#TroubleshootingguidemigratingfromStruts2.0.xto2.1.x-MissingProperties
主要内容如下：
Missing Properties
This message states that the framework searched for a property in the value stack and failed to find it.
2008-04-19 14:21:08,177 WARN [http-8443-Processor25] [OgnlValueStack] Could not find property [templateDir]
2008-04-19 14:21:08,177 WARN [http-8443-Processor25] [OgnlValueStack] Could not find property [templateDir]

eg. Include a new limit category in your log4j.xml file (only log errors or worse):
<category name="com.opensymphony.xwork2.ognl.OgnlValueStack">
<priority value="error"/>
</category>原来是少了log4j配置文件，顿悟+无语。。。。。看一下lib包，果然没有log4j-xxx.jar,到apache下个log4j-1.2.9.jar包放到lib下。现在不需要写log4.xml也不会出现警告信息。如果加上去也可以，把日志信息的级别调整为ERRORJ即可。若水用的是log4j.properties文件并没有用log4j.xml（个人习惯而已），考虑到有些朋友对log4j不太熟悉贴一下代码log4j.properties 放在src目录下就好了，记得在系统盘上建立log4j.appender.logfile.File对应的文件。
