最近用struts2发现后台总是出现各种警告，于是开始解决 warning

信息: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

于是找了好多资料才发现：

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]
2008-04-19 14:21:08,177 WARN  [http-8443-Processor25] [OgnlValueStack] Could not find property [templateDir]
2008-04-19 14:21:08,178 WARN  [http-8443-Processor25] [OgnlValueStack] Could not find property [org.apache.catalina.jsp_file]

To hide these messages, turn off the WARN level logging for OgnlValueStack.

eg. Include a new limit category in your log4j.xml file (only log errors or worse):

<span style="color:#000000;"><span class="code-tag"><category name=<span class="code-quote">"com.opensymphony.xwork2.ognl.OgnlValueStack"</span>></span>
      <span class="code-tag"><priority value=<span class="code-quote">"error"</span>/></span>
   <span class="code-tag"></category></span></span>

<span style="color:#000000;"><span class="code-tag">原来是少了log4j配置文件，顿悟+无语。。。。。</span></span>

<span style="color:#000000;"><span class="code-tag">看一下lib包，果然没有log4</span></span><span style="color:#000000;"><span class="code-tag">j-xxx.jar,到apache下个log4j-1.2.9.jar包放到lib下。</span></span>

<span style="color:#000000;"><span class="code-tag">现在不需要写log4.xml也不会出现警告信息。</span></span>

<span style="color:#000000;"><span class="code-tag">如果加上去也可以，把日志信息的级别调整为ERRORJ即可。</span></span>

<span style="color:#000000;"><span class="code-tag">若水用的是log4j.properties文件并没有用log4j.xml</span></span>（个人习惯而已），考虑到有些朋友对log4j不太熟悉

<span class="code-tag">贴一下代码</span>

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。

<span class="code-tag"># For JBoss: Avoid to setup log4j outside $JBOSS_HOME/server/default/deploy/log4j.xml

就是缺少
