Spring bean java.lang.NoSuchMethodError error

Question

I am getting below error, I believe its due to OLDER version of spring-beans.jar, In my LIB i have spring-beans--3.1.1.RELEASE.jar but still getting below error. I have deployed my application on WAS 8.5.X server.

java.lang.NoSuchMethodError: org/springframework/beans/MutablePropertyValues.add(Ljava/lang/String;Ljava/lang/Object;)Lorg/springframework/beans/MutablePropertyValues;

Is there any way to search on linux to find the culprit jar?

Answer 1

You can check what jar file that class is loaded from, adding the line below to your Java program

System.out.println(System.class.getResource(
           "/org/springframework/beans/MutablePropertyValues.class"));

which should print something like

jar:file:/C:/my-program/lib/spring-beans-5.2.1.RELEASE.jar!/org/springframework/beans/MutablePropertyValues.class

or using Guava's Resources.getResource("org/springframework/beans/MutablePropertyValues.class");

---

NoSuchMethodError error usually means there is a mismatch between the version of that class and the version expected by its clients. It could eventually be the case that the spring-beans jar version is actually correct- if that is the case, it is worth checking the version of the code invoking it, too.
