struts错误
用户验证时出现异常，一大堆异常代码。
奇怪的是web.xml中编译之前没有这些代码，
<servlet>
<servlet-name>debugjsp</servlet-name>
<description>Added by JBuilder to compile JSPs with debug info</description>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class> 这行org.apache下面出现错误标志
<init-param>
<param-name>classdebuginfo</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>
编译之后出现了，说是unale to find java class on classpath:servlet-class
请问这是怎么回事啊
