系统配置为 tomcat 6 +jdk 1.5，
出现java.lang.NoClassDefFoundError。
系统manger example均运行正常，只有新加的应用中导入class出现这个问题。
context文件放置在conf/C*/lo*/下面，内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/nj-jsl" docBase="/usr/T/e/webapp"
      debug="0" swallowOutput="true" reloadable="true">
  <Valve className="org.apache.catalina.valves.AccessLogValve"
      directory="/usr/T/e/log"  prefix="access_log." suffix=".txt"
      pattern="%t %h %r"/>
  <Logger className="org.apache.catalina.logger.FileLogger"
      directory="/usr/T/e/log"  prefix="etouch_log." suffix=".txt"
      timestamp="true"/>
  <

arameter name="HotelID" value="nj-jsl"
override="false"/>
<

arameter name="ConfigDir" value="/usr/T/U"
         override="false"/>
</Context>

web.xml 放置在 /usr/TouchLink/eTouch/webapp下面，内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app>
  <display-name>etouch</display-name>
  <session-config>
<session-timeout>30</session-timeout>
  </session-config>
  <welcome-file-list>
<welcome-file>login.jsp</welcome-file>
  </welcome-file-list>
  <servlet>
<servlet-name>EtouchInit</servlet-name>
<servlet-class>com.gljx.etouch.web.EtouchInit</servlet-class>
<load-on-startup>1</load-on-startup>
  </servlet>
  <servlet>
<servlet-name>ExcelGenerator</servlet-name>
<servlet-class>com.gljx.etouch.web.ExcelGenerator</servlet-class>
  </servlet>
  <servlet-mapping>
<servlet-name>ExcelGenerator</servlet-name>
<url-pattern>*.xls</url-pattern>
  </servlet-mapping>
</web-app>

class文件放置在WEB-INF下面。
每次打开login.jsp页面提示如下错误：

以上问题在tomcat 4中均没有，一切正常，jdk版本，环境均与tomcat 4下一直。

请教各位了。谢谢！！！
