我是SOA / BPEL的新手，我按照本书中的教程尝试创建一个简单的SOA应用程序，但是当我尝试将以下代码部署到weblogic服务器时，出现以下错误：

Error(73): query "/p:input" is invalid, because step 'p:input' is not valid.
Error(75): query "/p:result/ p:message" is invalid, because step 'p:result' is not valid.

我做错了什么？

这是bpel流程代码

我正在使用SOA 11.1.1.6版本，我已经尝试在google上搜索，我意识到我的语法实际上与它们提供的内容相同，是否是我遗漏的任何命名空间或者什么？
