wsgen raising NoClassDefFoundError exceptions

问题

I'm learning Java web services form the "Java Web Services Up and Running" book. As stated, I compiled the classes (where stands the "Teams" web service) :

javac ch01/team/*.java

Then, when it comes to generating artifacts with this command (done in the "ch01/team directory) :

wsgen -cp . ch01.team.Teams

I get the following error :

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

Thank you for you help.

回答1:

Try to execute the wsgen command in the root directory of your application, not in the ch01/team directory. I think it should work, as you pass the package info in the command line.

Based on answer @eternay gave, here is what worked for me:

 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

I hope it will help someone.
