1、啟動tomcat時(shí)出現(xiàn)的問題：
嚴(yán)重: Exception during cleanup after start failed
LifecycleException: Container StandardContext[/MAMIS.myeclipse.bak] has not been started
解決方案：
把tomcat下conf里（\Tomcat 5.0\conf\Catalina\localhost）的相應(yīng)文件刪了就行了。
實(shí)在不行：連同\Tomcat 5.0\webapps和\Tomcat 5.0\work下的都刪了。
2、啟動tomcat時(shí)出現(xiàn)的問題：
2007-08-01 08:53:39,562 [ContextLoader] ERROR Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ModuleInfoService' defined in ServletContext resource [/WEB-INF/bean-service.xml]: Cannot resolve reference to bean 'ModuleInfoServiceImpl' while setting bean property 'target'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ModuleInfoServiceImpl' defined in ServletContext resource [/WEB-INF/bean-service.xml]: Cannot resolve reference to bean 'MaModbaseinfoDAO' while setting bean property 'maModbaseinfoDAO'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'MaModbaseinfoDAO' is defined
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ModuleInfoServiceImpl' defined in ServletContext resource [/WEB-INF/bean-service.xml]: Cannot resolve reference to bean 'MaModbaseinfoDAO' while setting bean property 'maModbaseinfoDAO'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'MaModbaseinfoDAO' is defined
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'MaModbaseinfoDAO' is defined
……
解決方案：
bean-service.xml，bean-dao.xml里的配置有問題，如確定沒有問題了，再看service實(shí)現(xiàn)類里的DAO是不是已經(jīng)寫get,set方法了？
3、頁面提示問題
HTTP Status 404 - /MAMIS/
--------------------------------------------------------------------------------
type Status report
message /MAMIS/
description The requested resource (/MAMIS/) is not available.
--------------------------------------------------------------------------------
Apache Tomcat/5.0.28
解決方案：
404一般都為配置文件的問題。
4、tomcat報(bào)錯(cuò)：
ERROR Cannot create JDBC driver of class 'com.informix.jdbc.IfxDriver' for connect URL '
jdbc:informix-sqli://?.?.?.?:****/mamis:INFORMIXSERVER=mamis;NEWCODESET=gbk,8859-1,819
解決方案：
spring配置文件有錯(cuò)。
正確寫法：
<property name="url">
<value>jdbc:informix-sqli://?.?.?.?:****:informixserver=mamis_ser_tcp;database=mamis</value>
</property>
錯(cuò)誤寫法：
<property name="url">
<value>
jdbc:informix-sqli://?.?.?.?:****:informixserver=mamis_ser_tcp;database=mamis
</value>
</property>
(2007-08-16:)
5、tomcat報(bào)錯(cuò)
2007-08-17 10:49:19,156 [ProgramAimChildAction] ERROR org.springframework.orm.hibernate3.HibernateSystemException: Illegal attempt to associate a collection with two open sessions; nested exception is org.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions
org.springframework.orm.hibernate3.HibernateSystemException: Illegal attempt to associate a collection with two open sessions; nested exception is org.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions
org.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions
解決方案：將getHibernateTemplate().update(object)，修改為getHibernateTemplate().merge(object)
6、tomcat報(bào)錯(cuò)
org.springframework.dao.InvalidDataAccessApiUsageException: Write operations are not allowed in read-only mode (FlushMode.NEVER) - turn your Session into FlushMode.AUTO or remove 'readOnly' marker from transaction definition
at org.springframework.orm.hibernate3.HibernateTemplate.checkWriteOperationAllowed(HibernateTemplate.java:1098)

at org.springframework.orm.hibernate3.HibernateTemplate.saveOrUpdate(HibernateTemplate.java:690)
at com.cvicse.ks.mamis.common.dao.impl.BaseDAOImpl.updateObject(BaseDAOImpl.java:40)
解決方案：
在web.xml中加入藍(lán)色部分
<!-- 過濾spring中對于hibernate的session關(guān)閉管理 -->
<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>
org.springframework.orm.hibernate3.support.OpenSessionInViewFilter
</filter-class>
<init-param>
<param-name>singleSession</param-name>
<param-value>false</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>*.do</url-pattern>
</filter-mapping>
7、頁面報(bào)錯(cuò)
org.apache.jasper.JasperException: /jsp/system/promaintain/proInfoEdit.jsp(2,0) File "/WEB-INF/××××.tld" not found
解決方案：
對應(yīng)的標(biāo)簽文件在框架中的位置可能不對。
8、tomcat報(bào)錯(cuò)
ERROR a different object with the same identifier value was already associated with the session:
同一個(gè)session中關(guān)聯(lián)了兩個(gè)同ID的實(shí)體對象 。
我的代碼：
public void updateMaModbaseinfoShxx(MaModbaseinfo maModbaseinfo, String inid)
throws IllegalAccessException, InvocationTargetException {
// 模塊基本信息結(jié)果集
List moduleInfoList = new ArrayList();
// 根據(jù)項(xiàng)目內(nèi)部代號查詢模塊基本信息表
moduleInfoList = queryModule(inid);
// 存入記錄
for (int i = 0; i < moduleInfoList.size(); i++) {
MaModbaseinfo modInfoPO = new MaModbaseinfo();
MaModbaseinfoVO maModbaseinfoVO = new MaModbaseinfoVO();
maModbaseinfoVO = (MaModbaseinfoVO) moduleInfoList.get(i);
BeanUtils.copyProperties(modInfoPO, maModbaseinfoVO);
modInfoPO.setAc(maModbaseinfo.getAc());
modInfoPO.setAd(maModbaseinfo.getAd());
modInfoPO.setAr(maModbaseinfo.getAr());
modInfoPO.setAn(maModbaseinfo.getAn());
maModbaseinfoDAO.updateObject(modInfoPO);
}
}
解決方案：因?yàn)閭鲄⒑蚽ew的對象同在引起的問題，所以不要在此方法中重新new一個(gè)對象。

解決方案：
jsp頁面中包含一些隱藏域出現(xiàn)問題。
