使用struts, 启动时提示The /WEB-INF/web.xml was not found.解决办法

[ERROR] 07-29 11:23 - The /WEB-INF/web.xml was not found.  (ActionServlet.java:1787)
java.net.ConnectException: Connection timed out: connect

原web.xml头部:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN" "http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
<web-app>




  <servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>


修改为
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Velocity中, Unable to find resource 'VM_global_library.vm' 问题解决办法


在tomcat等容器中发布带velocity的应用时, 出现 org.apache.velocity.exception.ResourceNotFoundException : Unable to find resource ...vm  的解决办法:

配置文件 velocity.properties 中, 如果有
resource.loader = file

file.resource.loader.description = Velocity File Resource Loader
file.resource.loader.class = org.apache.velocity.runtime.resource.loader.FileResourceLoader
file.resource.loader.path = .
file.resource.loader.cache = false
file.resource.loader.modificationCheckInterval = 2

这段, 全部注释掉即可.

若没有, 就在配置里写上以上内容, 并更改第三项为

file.resource.loader.class = org.apache.velocity.tools.view.WebappResourceLoader

velocity配置log4j过程及注意.

1。指定velocity.properties文件,  默认路径为 WEB-INF/velocity.properties 也可自定义路径, 在web.xml中
      <servlet>
        <servlet-name>velocity</servlet-name>
        <servlet-class>org.apache.velocity.tools.view.servlet.VelocityLayoutServlet</servlet-class>
        <init-param>
            <param-name>org.apache.velocity.properties</param-name>
            <param-value>/WEB-INF/config/velocity.properties</param-value>
        </init-param>
        <init-param>
            <param-name>org.apache.velocity.toolbox</param-name>
            <param-value>/WEB-INF/config/velocity-toolbox.xml</param-value>
        </init-param>
        <load-on-startup>5</load-on-startup>
      </servlet>
注意 load-on-startup 需要配置且靠后, 否则启动时看不到日志.

2。在velocity.properties中配置日程相关参数:
#----------------------------------------------------------------------------
#  default LogSystem to use: default: AvalonLogSystem
#----------------------------------------------------------------------------

runtime.log.logsystem.class = org.apache.velocity.runtime.log.SimpleLog4JLogSystem

runtime.log.logsystem.log4j.category = velocity_log

#----------------------------------------------------------------------------
# This controls if Runtime.error(), info() and warn() messages include the
# whole stack trace. The last property controls whether invalid references
# are logged.
#----------------------------------------------------------------------------

runtime.log.error.stacktrace = false
runtime.log.warn.stacktrace = false
runtime.log.info.stacktrace = false
runtime.log.invalid.reference = true


3\ 配置log4j.properties,  具体配置意义请参看log4j配置相关文档
log4j.rootLogger=INFO,CONSOLE,FILE
log4j.logger.velocity_log=INFO,CONSOLE,VELOCITY
log4j.addivity.org.apache=true

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Threshold=WARN
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.Encoding=GBK
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=[%-4p] %d{MM-dd HH:mm} - %m  %n

log4j.appender.VELOCITY=org.apache.log4j.FileAppender
log4j.appender.VELOCITY.File=E:/workspace/dwrt/WebRoot/log/velocity.log
log4j.appender.VELOCITY.Append=false
log4j.appender.VELOCITY.Encoding=GBK
log4j.appender.VELOCITY.layout=org.apache.log4j.PatternLayout
log4j.appender.VELOCITY.layout.ConversionPattern=[%-4p] %d{MM-dd HH:mm} - %m  %n
