Java Nosuchmethoderror But Method Exists
6.2 million programmers, just like you, helping each other. 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
No Such Method Error Ljava/lang/string
'Z' means that return type of doSmth() method is 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 nosuchmethoderror runtime 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 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 er

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: The method must

Join them; it only takes a minute: Sign up java.lang.NoSuchMethodError when the method definitely exists up no such vote 3 down vote favorite I have a Spring framework based Java web application, which has been built in SpringSource Tool Suite ("STS"), and a local copy of Apache Tomcat. We also have a internal production server, again running Tomcat. When I run the application on my development machine, and carry out a specific action in the web application, everything works correctly. However, when I deploy no such method the web application to Tomcat on the server (via a war file produced by maven), and repeat those aforementioned specific actions, I'm presented with some unexpected behaviour. When I checked the server tomcat log file, I found this... 2011-11-16 19:36:45,090 [http-8280-Processor1] ERROR [attachments] invoke - Servlet.service() for servlet attachments threw exception java.lang.NoSuchMethodError: net.wmfs.coalesce.aa.dao.MediaDao.updateAlfrescoNodeRef(Ljava/lang/Long;Ljava/lang/String;)V at net.wmfs.coalesce.aa.service.impl.MediaServiceImpl.doFileUpload(MediaServiceImpl.java:102) at net.wmfs.coalesce.aa.servlet.MediaServlet.doFileUpload(MediaServlet.java:83) at net.wmfs.coalesce.aa.servlet.MediaServlet.doPost(MediaServlet.java:55) Now, the updateAlfrescoNodeRef method definitly exists in the MediaDao class - otherwise my code would not compile in STS... package net.wmfs.coalesce.aa.dao; public class MediaDao extends JdbcDaoSupport { public void updateAlfrescoNodeRef(final Long recordId, final String nodeRef) { // java code } } As you can see, the method signature is correct. I suspected that there may have been a problem when maven produced the war file, so I extracted the war files contents. In the WEB-INF/lib folder, I found the jar file which holds the MediaDao class, and extracted its contents. I then did a... cat ./MediaDao.class Now, as class files are binary files, I mostly saw gobledegook. However, I was able to clearly make out references to the updateAlfrescoNodeRef method, as well as the contents of a String in that method. So, this means that the method is definit
