这是我的web.xml配置:
<servlet>
<servlet-name>pieChart</servlet-name>
<servlet-class>com.mz.tl.chart.servlet.ImagePieChartSetvlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>pieChart</servlet-name>
<url-pattern>/pieChartServlet</url-pattern>
</servlet-mapping>

我的服务器是websphere,为什么老是访问不了servlet,一访问就报错,,
Error 404: SRVE0203E: Servlet [pieChart]：找到 com.mz.tl.chart.servlet.ImagePieChartSetvlet，但缺少另一个必需类。 SRVE0206E: 此错误通常意味着 servlet 最初是用服务器找不到的类来编译的。 SRVE0187E: 检查您的类路径，以确保 servlet 需要的所有类都存在。SRVE0210I: 通过仅使用应用程序的运行时类路径中的类重新编译 servlet，可以调试此问题 SRVE0234I: 应用程序类路径=[D:\WAS\IBM\WebSphere\AppServer\java\lib;D:\WAS\IBM\WebSphere\AppServer\java\lib\dt.jar;D:\WAS\IBM\WebSphere\AppServer\java\lib\htmlconverter.jar;D:\WAS\IBM\WebSphere\AppServer\java\lib\jardiff.jar;D:\WAS\IBM\WebSphere\AppServer\java\lib\jnlp

这是报的错误.
问题补充：
那个servlet放到tomcat里面可以执行成功,放到websphere里面执行就错了,我都是打war包到websphere里面执行的.
