Join them; it only takes a minute: Sign up Java “NoSuchMethodError” up vote 21 down vote favorite I'm getting: NoSuchMethodError: com.foo.SomeService.doSmth()Z Am I understanding correctly that this 'Z' means that return type of doSmth() method is no such method error ljava/lang/string boolean? If true, then that kind of method really does not exist because this method returns some Collection. But on the other hand if I call this method, I'm not assigning its return value to any variable. I just call this method like this: service.doSmth(); Any ideas why this error occurs? All necessary JAR files exist and all other methods from this class seems to exist. java nosuchmethoderror share|improve this question edited Feb 8 '14 at

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. share|improve this answer answered Sep 12 '10 at 15:27 amorfis 6,11284487 add a comment| up vote 17 down vote Normally, this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed.
