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 did use such a method within a CollectionUtils.filter method, where my method returned the Predicate. Weird enough that I switched it back as it was and now it works, don't understand that actually .. –BAER Nov 19 '14 at 9:02 add a comment| 7 Answers 7 active oldest votes up vote 22 down vote accepted 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. 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.

More specifically, it is looking for a method that is declared as follows: package some; public class AppName { ... public static void main(String[] args) { // body of main method follows ... } } The specific requirements for the entry point method are: T
