Look at the stack trace ... If the exception appears when calling a method on an object in a library, you are most likely using separate versions of the library when compiling and running. Make sure you have the right version both places. If the exception appears when calling a method on objects instantiated by classes you made, then your build process seems to be faulty. Make sure the class files that you are actually running are updated when you compile. share|improve this answer answered Aug 29 '08 at 20:14 Vetle 1,35311626 We recently discovered the cause of one of these and it turned out the build process was putting class files in place before the java server was shut down, and we hit this because the java server hadn't loaded some classes, and then it did load some but it got these new ones, and since the new code referred to methods that the old classes didn't have... bingo, NoSuchMe

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 http://stackoverflow.com/questions/3695340/java-nosuchmethoderror 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 '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 meth
