wsgen引发NoClassDefFoundError异常

Question

我正在从《Java web services Up and Running》这本书中学习Java web服务。如前所述，我编译了这些类(其中包含"Teams"web服务):

javac ch01/team/*.java

然后，当使用以下命令生成工件时(在"ch01/team目录"中完成):

wsgen -cp . ch01.team.Teams

我得到以下错误:

Exception in thread "main" java.lang.NoClassDefFoundError: Teams (wrong name: ch01/team/Teams)

谢谢你的帮助

Answer 1

尝试在应用程序的根目录中执行wsgen命令，而不是在ch01/team目录中。当你在命令行中传递包信息时，我认为它应该可以工作。

Answer 2

根据@eternay给出的答案，以下是对我有效的方法:

 1. cd to project root directory
 2. issued wsgen -verbose -cp bin [package].ServiceImpl -wsdl
 3. "bin" being the root of .class files, and may be switched to "target" if you are using maven

我希望它能帮助到别人。
