Java “NoSuchMethodError”

Question

I\'m getting:

NoSuchMethodError: com.foo.SomeService.doSmth()Z

Am I understanding correctly that this \'Z\' means that return

Answer 1

Looks like method exists in classpath during compilation, but not during running of your application.

I don't think return type is a problem. If it was, it wouldn't compile. Compiler throws error when method call is ambiguous, and it is when two methods differ only by return type.
