可以看一下程序所用的jdk版本，Weblogic8.1好像只支持jdk1.4

你的web.xml有问题，请问你的servlet是哪个版本的，weblogic81只支持servlet2.3以下的版本。

我也遇到过这样jsp/servlet没有找到的情况，不知道你的跟我的是不是一样的。
你看你的这个错：
Servlet class cn.com.servlet.LawAppendServlet for servlet LawAppendServlet could not be loaded because the requested class was not found in the classpath C:\bea\user_projects\domains\mydomain\applications\dangerManage\WEB-INF\classes;C:\bea\user_projects\domains\mydomain\myserver\.wlnotdelete\extract\myserver__appsdir_dangerManage_dir_dangerManage\jarfiles\WEB-INF\lib\classes12.jar;C:\bea\user_projects\domains\mydomain\myserver\.wlnotdelete\extract\myserver__appsdir_dangerManage_dir_dangerManage\jarfiles\WEB-INF\lib\jdom.jar;C:\bea\user_projects\domains\mydomain\myserver\.wlnotdelete\extract\myserver__appsdir_dangerManage_dir_dangerManage\jarfiles\WEB-INF\lib\sparknet.jar;C:\bea\user_projects\domains\mydomain\myserver\.wlnotdelete\extract\myserver__appsdir_dangerManage_dir_dangerManage.
说在classpath中没有找到这个LawAppendServlet。看一下下面的这些路径，应该确实没有包含。
为什么没有包含？我不知道你的是不是跟我一样，我是因为在web.xml中，有这么一段话：
<servlet>
<servlet-name> JSPClassServlet </servlet-name>
<servlet-class> weblogic.servlet.JSPClassServlet </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> JSPClassServlet </servlet-name>
<url-pattern> *.jsp </url-pattern>
</servlet-mapping>
看看你的有没有？如果有，去掉，重启，Ok。我的问题是这样解决的。
这段话是什么意思？google一下，找到答案：
在Weblogic中发布Web Application工程时，为了保护JSP文件避免未经授权的访问和窥视，可以用weblogic.jspc把JSP文件precompile成为servlet文件，放到WEB-INF/classes目录下。基于Servlet的声明，WEB-INF不作为Web应用的公共文档树的一部分。因而，WEB-INF目录下的资源不是为客户直接服务的，这样就可以一定程度上保证JSP的安全。
要达到这样的功能，除了在web.xml中要有上面那段外，还要在weblogic.xml写：
<jsp-param>
<param-name> precompile </param-name>
<param-value> true </param-value>
</jsp-param>
把预编译开启，让server在启动的时候预编译jsp。或者手工用weblogic.jspc编后放过去（C:\bea\user_projects\domains\mydomain\applications\dangerManage\WEB-INF\classes）。当然，预编译带来的后果就是启动的时候慢，我遇到的那个就是很大，启动一次要编译半个小时以上。
祝你好运。
