java - servlet加载异常

Question

当我尝试在服务器上运行时，出现以下严重错误:

我的路径中包含最新的 Spring-servlet 和 spring-ws jar。我不想因为添加您不需要的代码而负担过重，因此您认为我应该包括的任何部分都请告诉我。我确定这只是我忘记或放错地方的小东西。

我已经仔细检查过，我的 spring-ws jar 中确实包含 org.springframework.ws.transport.http.MessageDispatcherServlet。此文件夹包含在库构建路径下仍然遇到同样的问题。

Answer 1

确保 classpath 中有一个 spring-ws-*.jar，Log 本身说找不到类。

java.lang.ClassNotFoundException: org.springframework.ws.transport.http.MessageDispatcherServlet

可以找到包含此类的 jar here .
