Re: [jakartaee-platform-dev] Transitioning Jakarta EE to the jakarta namespace
|
Hi Jan,
Dependency graph is a view for helping, I hope. But it's don't say that
transition will be simple.
Goal is to have global picture for dependency view (API only, i agree)
Following dependencies are visible on graph :
javax.activation.DataSource (dependency javax.xml.bind ->
javax.activation)
javax.xml.bind.JAXBElement
Following dependencies aren't visible on graph :
javax.validation.ValidationException
javax.xml.ws.Provider
But these are constraints for implementation.
This graph concern API only, you are right, the task is more complex for
implementation of each specifications.
But Users concerns must be to front. Because success of this transition
is adoption for developers, customers and community.
Regard,
Lilian.

Hi,
I am afraid the transition would be more complex than what the graph
shows. I assume the dependencies are taken from the APIs in the graph.
The Specification is more than just the API, however, it is the
Specification document, too. For instance, JAX-RS Spec document
mentions the following dependencies:
|javax.activation.DataSource|
|javax.xml.bind.JAXBElement|
|javax.validation.ValidationException|
|javax.xml.ws.Provider|
These should be taken into an account as well.
Best,
Jan

Hi,
I have generated dependency graph from your program with plantuml.
I think that it's more explicit than text only
I added also color to distinguish simple or complex case.
- green - simple case
- yellow - complex case
The image is accessed at
https://raw.githubusercontent.com/lilian-benoit/jkta/master/src/main/resources/depends.png
I have realized PR pour add this functionality
https://github.com/tomitribe/jkta/pull/1
Currently, i generated text file. This file is passed as argument to
program plantuml.jar
Best regards,
Lilian.

Ok folks, more data for us to look at.
I've created a report of transitive dependents to answer the
question,
"if we rename api foo, what else has to be renamed?"
-
https://github.com/eclipse-ee4j/jakartaee-platform/blob/master/namespace/transitive.adoc
Note we did have a report that showed maven dependencies. This is
the
logical inverse of a maven dependency graph. It's the incoming
dependencies, transitively walked backwards.
An example of why this is important.
- fact: javax.ejb has a maven dependency on javax.transaction,
javax.xml.rpc and javax.xml.rpc.soap
- question: Does renaming javax.ejb cause javax.transaction,
javax.xml.rpc and avax.xml.rpc.soap to be renamed?
- answer: No. These apis do not have a reference to javax.ejb and
therefore could stay in javax even if javax.ejb is renamed
This graph was created by collecting all the jars published to Maven
central in the jakarta groupId, parsing them with ASM to collect any
form of "import", then chopping them up by logical api package.
If you want to play with the code, you can find it here. I apologize
in advance for the relative mess -- the code wasn't really created
for
sharing and therefore will be hard to follow.
