原因：
在weblogic上部署war包的话，默认是不展开的，所以如下的hibernate配置不能解析。
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="mappingDirectoryLocations">
<list>
<value>classpath:/com/edu/nts/entity</value>
</list>
</property>
</bean>
解决办法：
针对weblogic的部署方式，必须改为如下方式。
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="mappingResources">
<list>
<value>com/edu/nts/entity/AidStudentInfo.hbm.xml</value>
<value>com/edu/nts/entity/AidStudentList.hbm.xml</value>
<value>com/edu/nts/entity/AidStudentListTemp.hbm.xml</value>
。。。
</list>
</bean>
虽然没法偷懒用上面的注入方式，但还是可以通过编写一个小程序生成上面的明细注入片段，修改量不会太大。

原因：
在web.xml中log4j的配置方式问题，默认情况log4j.properties放在classes目录下，而由于war没展开，找不到这个文件，所以把它直接放WEB-INF目录下，并去掉原来web.xml里面的如下配置：
<servlet>
<servlet-name>log4j</servlet-name>
<servlet-class>
org.springframework.web.util.Log4jConfigServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
解决办法：
新建一个servlet，初始化log4j配置文件：
public void init() throws ServletException {
InputStream is = getServletContext().getResourceAsStream(
"/WEB-INF/log4j.properties");
Properties props = new Properties();
try {
props.load(is);
} catch (IOException e) {
System.err.println("Load log4j configuration failed");
}
PropertyConfigurator.configure(props);
}
并注册到web.xml文件中：
<servlet>
<servlet-name>Log4jInitServlet</servlet-name>
<servlet-class>com.edu.nts.web.servlet.Log4jInitServlet</servlet-class>
<load-on-startup>0</load-on-startup>
</servlet>
问题三：
由于种种原因，该应用程序必须部署到服务器的根目录（/）下面，否则样式及功能都会出现问题。
解决办法：
为了把应用程序的context root改到根目录，创建了一个weblogic.xml文件，放到war包的WEB-INF目录下，内容如：
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="
http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd
http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.0/weblogic-web-app.xsd">
<weblogic-version>10.3.2</weblogic-version>
<context-root>/</context-root>
</weblogic-web-app>
问题四：
打开登录页面报错，后台错误如下：
####<2011-4-2

<%@ page language="java" pageEncoding="UTF-8"%>
^---------------------------------------------^
>
原因：jar包冲突，以及jar包加载顺序的问题引起
解决办法：
删除lib目录下的xml-apis.jar，并在上面的weblogic.xml中增加如下：
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
使classloader首先加载web－info下的jar文件，修改后的weblogic.xml如下：
<?xml version="1.0" encoding="UTF-8"?>
<weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="

原因：
配置的weblogic连接池名称命民规则问题。
解决办法：
由于数据源的jndi为：jdbc/orcl，数据源的名称必须为jdbc.orcl，否则就会报上面的类似错误。
问题六：
错误信息忘记了，页面访问报编译错误。
原因：
类似如下的jstl判断语法不能正确解析，真是奇怪
${changeForm.change.oldVal == 1 ?
男 : changeForm.change.oldVal ==0?女:’’}
解决办法：
采用choose语法修改为如下
<c:choose>
<c:when test="${ changeForm.change.oldVal ==1}">男</c:when>
<c:when test="${ changeForm.change.oldVal ==0}">女</c:when>
<c:otherwise></c:otherwise>
</c:choose>
问题七：
getServletContext().getRealPath("/upload");返回为null的问题。
原因：
由于weblogic下，war没有展开，所以也就不存在相对于应用程序的路径realpath。
解决办法：
若是为了得到相对路径，采用以下方式
getServletContext().getResource("/upload").getPath();
若是为了加载资源文件，则采用如下方式
InputStream is = getServletContext().getResourceAsStream(
"/WEB-INF/log4j.properties");
Properties props = new Properties();
try {
props.load(is);
} catch (IOException e) {
System.err.println("Load log4j configuration failed");
}
PropertyConfigurator.configure(props);
问题八：
采用jquery的方式异步请求后台数据，后台采用PrintWriter返回结果，结果页面不能正确加载数据。
原因：
PrintWriter writer = (PrintWriter) response.getWriter();
writer.write("failure");
writer.close();
以上close之前，少了一句
PrintWriter writer = (PrintWriter) response.getWriter();
writer.write("failure");
writer.flush();
writer.close();
