Could not add parameter to operation. You must specify either its Java or XML type.

My environment:
- JBuilder
- Weblogic Platform 8.1
- Windows XP SP2



I've got the following error when I try to build document-oriented web services

解决办法 ：

将Jbuilder  Webservice 生成方式  Service style   由 document 改为 rpc
