I am currently studying for the 1ZO-815. package name is called is
namespace.
package mypackge <--- namespace
public class Main {
public static void main(String[] args) {
System.out.println("execute");
}
}

I apologize for mistaking overriding method vs class in your
description. I turned on debugging and it looks that all three classes
are being found and struts actions are being created. The problem
appears to be allowing the default process to create those - they get
created with the same action name [hello-world] and namespace [].
Struts in that case I believe takes the first encountered just like
when using a struts.xml file. I don't use the Convention Plugin but I
would suggest a solution might be to use the @Namespace annotation on
the class or package. That way you would be able to specify a unique
SCOPE when calling the action and get the result you need.

As you see when you declare the same functionality using the
struts.xml Then only that explicitly declared
method will be executed by the struts API [framework] in the
explicitly declared package.class.
Overriding methods in OOP means not using certain declared methods
from inherited classes and super impose on inherited methods by
writing your own methods.
So you use some methods from the inherited class not all [Pick and
choose, adapt]
This is randomly picking up a class by matching the class names only.
There is no way to match packages names same as stuts.xml due to
design of
annotation API. So I am suggesting do a match of same class names [
validation method in the annotations API ] and raising an error to the
application developer of presence of duplicate class names.

Overriding methods *is **a valid feature* in Java and probably all

wouldn't be able to avoid methods being overridden. Above those layers
of code you have many more layers of code to provide the ability to
communicate with and over web technologies. Again with a high
probability of more methods being overridden. Eventually you get to the
Struts framework which is not flat. It is again layers of code, with
again a high probability of more methods being overridden.
IMHO A developer needs to understand the technology stack used
including
the order of classpaths searched at execution time. A framework is
intended to help you do a job which implies you know what it's doing.

I think the convention plugin should perform a validation a check for
the
presence of multiple same class names within different
package names. That ambiguity has been shown by my test.
After all it is quite feasible and likely that we could have multiple
same
class names from different package names
from jars which have been placed on the classpath.
We cant have the convention plugin randomly (as shown by my test)
executing random code.

Hi,
I guess that the behavior of defining actions with same name and
namespace
is undefined. I think it's not an issue because Convention Plugin
has
no
avenue to distinguish between them when you request
http://localhost:8080/hello-world.

Subject: convention plugin Issue
Hi,
On this page
https://struts.apache.org/plugins/convention/#setup
if I have com.example.actions.HelloWorld.java
and
uk.mypackage.actions.HelloWorld.java
with url http://localhost:8080/hello-world then
uk.mypackage.actions.HelloWorld.java execute is run.
If I have
uk.example.actions.HelloWorld.java
and
com.example.actions.HelloWorld.java
then com.example.actions.HelloWorld.java execute is run.
uk.mypackage.actions.HelloWorld,java overrides the other two.
