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 boolean? If true, then https://docs.oracle.com/javase/7/docs/api/java/lang/NoSuchMethodError.html 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 12:03 Sam Rad 7,46352241 asked Sep 12 http://stackoverflow.com/questions/3695340/java-nosuchmethoderror '10 at 15:19 vrm 65221224 2 Perhaps you're using it in a if/while? if( service.doSmth() ) ?? –OscarRyz Sep 12 '10 at 15:23 possible duplicate of How do I fix a NoSuchMethodError?, Interpreting java.lang.NoSuchMethodError message, etc. –Pascal Thivent Sep 12 '10 at 15:34 1 Although it is ages ago, I have to thank @OscarRyz for his answer. 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. In short - a class/jar file at runtime is not the same that you used at compile time. share|improve this answer answered Sep 12
