web.xml在WEB-INF目录下面.
x卛_解决出现上述的问题了.
在JSP打开EXCEL文g
1.通过配置web.xml(tomcat\conf)Q实现在JSP打开EXCEL文g的功?
在WEB.xml(tomcat\conf)中加入如下代?
<mime-mapping>
<extension>xls</extension>
<mime-type>application/msexcel</mime-type>
</mime-mapping>
2.如果需要文件以EXCEL形式打开Q则在JSP文g头部增加如下配置
<%@ page contentType="application/vnd.ms-excel" %>

log4jQ可以有如下的creamQ?
1. 动态的改变记录U别和策略，不需要重启Web应用Q如《Effective Enterprise Java》所说?
2. 把log文g定在 /WEB-INF/logs/ 而不需要写l对路径?
3. 可以把log4j.properties和其他properties一h?WEB-INF/ Q而不是Class-Path?
在web.xml d
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>WEB-INF/log4j.properties</param-value>
</context-param>
<context-param>
<param-name>log4jRefreshInterval</param-name>
<param-value>60000</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
在上文的配置?
Log4jConfigListener会去WEB-INF/log4j.propeties d配置文g;
开一条watchdogU程?0U扫描一下配|文件的变化;
q把web目录的\径压入一个叫webapp.root的系l变量?
然后Q在log4j.properties 里就可以q样定义logfile位置
log4j.appender.logfile.File=${webapp.root}/WEB-INF/logs/myfuse.log
如果有多个web应用Q怕webapp.root变量重复Q可以在context-param里定义webAppRootKey?
在jboss中启动时出错Q?

按各位高手帮我看哈，谢谢?!!!!!!!!!!!!!!!!!!!!!!!111
===============================================
The error above is caused by jboss problem, see
http://jira.atlassian.com/browse/JRA-6823.
"
One way to solve the classloader issue is by reverting the JBoss configuration
to the old classloading model.
Edit the file
<jboss>/server/default/jbossweb-tomcat55.sar/META-INF/jboss-service.xml
Change the following lines:
<attribute name="Java2ClassLoadingCompliance">true</attribute>
<attribute name="UseJBossWebLoader">true</attribute>
(both are default set to false in jboss-4.0.2).

2.表单验证方式
使用表单验证方式q行web应用E序的n份验证，需要开发者定义一个登录页面和dp|的错误处理页面。登录页面可以时html、jsp或servlet。用这U验证方式的好处时可以对E序有更q一步的控制。登录页面应该让用户输入用户名和密码Q错误处理页面应该将验证p|的信息反馈给用户。开发用表单验证方式的web应用E序的基本步骤如下?br />Q?Q编写登录页面和错误处理面Q在web应用E序的欢q页面中加入到登录页面的链接Q提C用户首先进行登录。登录页面D例：
<
form

input
type
="text"
