both JARs contains the class org.apache.axis.encoding.Serializer. then, what could be the cause of this issue.

Since org.apache.axis.encoding.Serializer is indeed in axis-1.4-osgi.jar (you can check at https://www.findjar.com/jar/mule/dependencies/maven2/org/apache/axis/axis/1.4-osgi/axis-1.4-osgi.jar.html?all=true) my guess is that this class is present in your IDE at compile time, but not in the server classpath when the application is starting/running (by inspecting the stacktrace, looks like you are trying to run a web application and the exception occurs at runtime).
