java.lang.NoSuchMethodError : org.apache.commons.io.FileUtils.isSymLink(Ljava/io/File;)Z

Question

I am getting this error while importing the data using sqoop(master machine) from oracle db which is in different machine(i.e., slave machine). I have replaced the commons.io.jar file also.

Answer 1

This is nothing related to any particular library. This is a general exception in java

The problem is quite simple. The method was available at Compile time but not at run time.

One of the reasons can be that you are using the wrong version of the commons library. Just open that jar file in any zip viewer and go to that particular location where that class can be found, the location will be something like org/apache/commons/io/FileUtils and decompile that class using some class decompiler and check whether that method which the ie isSymLink(Ljava/io/File;)Z compiler is complaining is available in that class.

It can also happen that the method is there but the method signature is different

Answer 2

Maybe I'm late, but just faced the same issue and could solve it. The solution for me is to indicate in the weblogic.xml that your jar must override the same existing in weblogic:

<weblogic-web-app ...>
<container-descriptor>
    <prefer-application-packages>
        <package-name>org.apache.commons*</package-name>
    </prefer-application-packages>
</container-descriptor>
