pom files

Hi Murod

Hope this finds you well. I remember you were busy in Delhi
rationilizing the pom files in the dhis2 project. Did you get this
finished? It would be good to be able to build/debug/profile through
a single project.

Regards
Bob

I agree, this is on my wishlist as well. Can I get that pom.xml if committing it to the trunk is an issue

Hey Murod good to hear from you.

Hi Bob,

Yes, there changes to be made on poms to make dhis2 as single project. Also there are special requirements/plugins to get project into eclipse. I will write on mailing list soon on how to run/debug modules with WTP (develop as you deploy, maven-eclipse-tomcat), etc., but I need to discuss this with Lars before that. What I have done is on module level, projectwise it needs more work.
Now I am working on webwork to struts2 migration as well as upgrading hibernate to latest release and use of annotations (JPA and Hibernate). These all should be discussed in mailing list before we take steps, because they are major changes and need surrow revision and testing.

So, lets start on discussing these issues on WHYs, HOWs WHOs and WHENs scopes.

These are indeed major changes - would be good to see a proposal on the list.

Cheers
Bob

Murod,

  • What do you mean by upgrading to the latest Hibernate release? We are already running the latest one in the maven repo, 3.2.6.ga.

  • What would be the reason for switching to Hibernate/JPA annotations?

  • Why are you working with struts2 migration? Have we decided to switch? Is this something we should prioritize right now as there are lots of pressing requirements, like the list we put down a few weeks ago?

Lars

Yes, we have a list of pressing requirements, one is implementing “easy-access-help” and the other is "datavalue-history ". For implementing first one I had small discussion with you, and we decided that I will look shortly if migrating from webwork to struts2 is possible. I managed to migrate one module to run on struts2, it is possible but takes some time and efforts. As all of us know webwork is not updated since mid 2007. “easy access help” was implemented, now I am working on second one. Hibernate has support for auditing persistent objects (“datavalue history”), that is what we want. But it comes with annotations only, so I decided to change hibernate libraries to host annotations, this is the reason. I think using existing functionality is much better than hand crafting history object for datavalue table. Latest Hibernate Core is 3.3.1.GA and Hibernate Annotations is 3.4.0 GA.
Why I said to Bob I am wotrking on this and that is because I have all in my branch and cannot split easily what he wants (poms). I cannot distribute pom with new hibernate dependencies, struts2, etc. That’s WHY I said lets discuss these issues before we have made such a change. It is better to discuss how to make these things happen, if they are useful. For hibernate I can say transision is transparent, we can move one object to annotation, while others are still in hbm.xml. For struts2 the same applies to some extend.

murod.

Yes, but we should still have a review of struts 2 before launching into it… Anyway there are hundreds of action classes, interceptors etc and it will be a big job to change things.

Nice.

OK. If you can use this side-by-side it sounds like a good idea. Sorry if I am sticking my nose in everything, just interested in hearing the rationale behind it…

Yes, we have a list of pressing requirements, one is implementing
"easy-access-help" and the other is "datavalue-history". For implementing
first one I had small discussion with you, and we decided that I will look
shortly if migrating from webwork to struts2 is possible. I managed to
migrate one module to run on struts2, it is possible but takes some time and
efforts. As all of us know webwork is not updated since mid 2007

Yes, but we should still have a review of struts 2 before launching into
it... Anyway there are hundreds of action classes, interceptors etc and it
will be a big job to change things.

My count is just over 400 actions. And considerably fewer
interceptors. Mind you the transition from webwork to struts2 doesn't
appear catastrophic
(http://struts.apache.org/2.0.14/docs/key-changes-from-webwork-2.html\)
and probably a good bit could be automated. But I know, the devil is
always in the detail :slight_smile: But I agree with Murod - sitting on webwork
past its expiry date is a risk. The trouble is that such a migration
can't be a gradual one like the hibernate case. I guess it would be a
case of migrate one and all ...

Reminds me how it would be really useful to have some sort of selenium
test suite I wonder what came of Satvik's efforts to put together a
list of test cases for the webapp. Satvik, I saw the beginning of
this - can you share what you have?

What would the steps be in looking at such a proposal? Something like
1. review of struts2 and its differences from webwork leading to a
decision and prioritisation
2. compilation of selenium style battery tests covering at least the
results of 400 actions! Probably not all at once, but generally
something useful in itself.
3. creation of a migration branch
4. auto-convert as much as possible
5. cycle of test and fix what's still broken

"easy access help" was implemented, now I am working on second one.

Nice.

Hibernate has support for auditing persistent objects ("datavalue
history"), that is what we want. But it comes with annotations only, so I

Why I said to Bob I am wotrking on this and that is because I have all in
my branch and cannot split easily what he wants (poms). I cannot distribute
pom with new hibernate dependencies, struts2, etc.

I think that it would be really useful to be able to fix the poms with
the existing dependencies rather than wait for the outcome of what
might be a long and uncertain process. If you can just send the poms
I'd love to have a look. I'm far from a maven expert, but I'm getting
better.

On unix like systems (including probably cygwin):

find . -iname pom.xml |zip poms.zip -@

That's WHY I said lets
discuss these issues before we have made such a change. It is better to
discuss how to make these things happen, if they are useful. For hibernate I
can say transision is transparent, we can move one object to annotation,
while others are still in hbm.xml.

OK. If you can use this side-by-side it sounds like a good idea. Sorry if I
am sticking my nose in everything, just interested in hearing the rationale
behind it...

This gradual transition sounds do-able. Though I guess we are still
talking about a hibernate library upgrade even while still using a
mixture of modes.

Sounds reasonable.

I am not saying switching to struts is a bad thing (I guess struts2 is more of a webwork continuation with some struts additions ++), just that it takes time and its a question of priority…
