A

Yes,, thank you again from us gas say you were there and anticipated the unit for us. We want to show that as a highlight right now, but ok, then we’ll jump over it in exactly a quarter of an hour. We’Ll continue with the next presentation. Yes, then, at some point.

B

It will continue also.

A

Here and exactly we always have a 15-minute studio program in between where we do different interviews. Jan falk and I just talk about a few topics where people can ask questions at any time exactly the first topic we have chosen so the specification of jakarta, where we just.

A

Want to do an all-round flight over it, the specification where do you find them? What are they and the simplest thing is really on the jakarta website. That's carta.info ban directly pacific agence. Where you you can look at them,, you can read through the documentation, etc., and they are now real t, some, so I don't even know if it wasn't counted. How many are so that's.

B

Around 30 years in total, some are now optional and no longer maintained. They actually don't appear here anymore at the time so xml binding eg is still as specification, but included as optional specifications in the new release and, of course, still available exactly.

A

And what we saw here was that you already told them. There are really some things that have been updated faces. Let's take version 4.0, for example, so really partial major update, also like, for example, from 13 02 40 faces 40 should be 60, and so a lot has really happened in the zemis a new specification. There is also a little something to say here that you have the unit there. You can certainly say a little more right away.

A

Yes, otherwise, that what I always like about all these specifications is that you don't have to know all the probes rn that you only have to deal with the ones you need for your application,. So you do n't have to know josef and faces to.

A

Write a web application with jakarta ii. If you want to build an application that actually only has rest, for example,, but all the things work and intertwine and work together. So the goal is that the unit.

A

Can also be used in vienna by faces or, for example, in service objects, or something like that.

B

A set of specifications was put together in certain versions and also tested for integration,, thus ensuring that an implementation can be built as a platform,, e.g. an application server that supports all of these versions at the same time and that the user can then actually use it,.

B

These are actual two different things and that is tested using the technology, compatibility kit, tck of the respective specification and the platform in the respective profiles, and so the many changes this is, so to speak, the processing of a technical debt, because the migration from plakat.de to the eclipse foundation was an edition of oracle that, when changes are made to the apis,, the namespace has to be changed from krawarik to sakata and that basically occupied the community for two years to.

B

Extract the effects and make the deepest case that was previously a secret thing that it was divided into many small ones share, so that it can be maintained more easily and which then belong to bacon, and the community has been waiting for all the developers to finally be able to read new features such as engines could finally read that was not possible with nine, so jakarta. Nine was basically just the change of the namespace it, but no changes to the apis other places. 91 then upgraded java.

B

Se 11 compatibility and poster e10 will finally finally finally deliver new features. There have been quite a few that have flowed in and that made it take a little longer, but I think it's worth what comes out of.

A

It you just mentioned a few keywords that we'll talk about again: later, such as the pace, we'll have a look at that later in a studio, session,, we'll take a look at what tc cases are,. What is the special pack structure,, like katy's specification, reference implementation,? What is that everything exactly? Where do you find what is open source and so on and so forth? All of this, we will look at again later that behind each of these boxes that we see here, there are usually four boxes, so tk specifications and reference implementation. Yes, where.

B

They are now compatible. Implementation means that is not the one reference implementation the iss used to be at jakarta. That was glass. Until recently, there may be one or more compatible implementations that are absolutely necessary in order to be able to complete the specification with a new release,.

B

So there must be an implementation that has also successfully implemented the specification also tested in the luggage has the specification to enjoy, and that was the main reason why it was so delayed, by the way,, because the compatible implementation had to follow all the steps and the which has become for the platforms has actually become the compatible implementation. The glass fish again.

B

Was not the compatible implementation for the individual specifications? Originally, everything had to be followed up in glas fisch that had already been successfully implemented elsewhere. There was very good support for a few years. At the end that should be mentioned separately. They have short donations from their implementation, back a classic done so that the current plan is halfway met, exciting, who is now.

A

Wondering how does the years ago know? What actually is we from the loan was afternoon about? It are meanwhile in the I would say large java working groups of the eclipse foundation, little jakarta micro profile and you behind me tips. Adoption represent and work there as a community in the end on this specification also have quite a special status because we are actually exactly the ones who don't represent a company, but really are the ones who come from outside the community.

A

I think we have something quite with the eoc created something cool, we'll talk about it again later, but maybe now again to the new core pro case. What's available in connection with the goal, the unit so.

B

The idea behind the basket prof that came from this cloud made of ottawa group that makes sense, would there are these profiles in jakarta a pplications. So originally there was only one platform, which was also called full profile.

B

When the idea came up many of the specifications, I don't need in my application at all, but I need them for special cases and then you can come up with the idea. Yes, then you define it a sud of the specification to be able to offer a small platform implementation, so to speak,.

B

That was the web profile, card, five or six came,, but that.

A

Was somehow the story.

B

B

Binz micro profile,, which is based on a whole set,, namely this set of jakarta specifications,,.

B

In principle, can you come up with the idea? Yes, we could actually define that for your core profile.

B

Then there would always be a basket in micro profile because with one version and that could then be drawn into microprof as a common dependency, and you would, so to speak,- have the core of jakarta in one bundle, a smaller profile,, which of course also helps release management ft. Because then you can then do the integration test at this level is.

A

Certainly also an interesting step to what you just said, bringing together the micro pro from jakarta, again,, bringing it closer together exactly this corp bofa and.

B

Lars mentioned that with products like quarks that can generate native images, so there was a feature that naturally reflects and that's not allowed,. That means you have to rebuild quarks that support city light or city 3x, but there were features that could never be implemented as a native image That's. Why contact is never officially any cdu that.

B

Could successfully complete the cds,, so it was never.

B

Glued to the ebox as proof of a certified implementation, so to speak,, and since several different implementations now also support these native images,. The idea came up that these features and iii were the ones times from a different id ee, dar immigrated and are actually hardly ever used,. So they said okay,.

B

We have the cdi in the full version, so to speak,, but there is a subset that is native image compatible and we extract it in cd white and we pack that into the corps,, so to speak as minimal without completely excluding the other users, so to speak,. But in order to make this score, profi compatible, so to speak,, for example, Quarks with native images,.

B

It was designed that way and that’s basically the biggest change that has flowed in again,.

A

The goal is the unit,, so you know, markus, and the micron local version is already there, whether they are based on the work 4.0 today or have the first.

B

A

After jakarta is e10,, I.

B

Can,, I assume they are working on it,. So of course, the wetter.net side is interested in being able to prove such a certification, because customers also ask for it, and quarks is enough for the degree of maturity so that it also supports the produ kt is offered then of course it’s great. If you can prove it so we’re working on it again. The status at quarks is not sure when exactly but was very interested in the fact that you can achieve a lot separately.

B

Certification for scorpio lately, I think that’s on there, the agenda and white fly, for example, the classic platform implementation,. The current release is already trimmed for profit,, so to speak,, cool, ok,, exciting,.

A

Yes, that 's a good thing, yes, exactly,, I think that's an important step, the whole thing, above all,. You can hard savings, then no longer use any things that you depend on. You actually do n't work, but you then have a dependency and everything that's in there then just works cleanly. So.

B

A small sticking point for the insiders the micro tread depth case because it's to survive, not bad. The underlying jakarta ee components at best hen, the tk, but only what is tested directly via integration tests. But if you want to use other features, so to speak,, then we take other features that the microphone specifications do not cover, for example,.

B

That is not important up to now be ensured and was also not verifiable, because it the profile, didn't exist and that it would n't be divided up either, and that makes it possible and in the background of course, with the division that the cgs that's something that's still going on, by the way,. There was this one big counter for the platforms where you had to sign a mobile phone to be able to see the contract at all, to possibly conclude a contract with oracle,.

A

B

To get insight so that you can let go of implementing it on your platform,, it's all open source now,, it's time for the eclipse foundation, and now it's still the big one, the task of dividing the tk into several parts and, so to speak, the tk part that belongs to a specification to extract from it and factors and thus to make them independent and to promote the further development, but also the.

A

Space we'll talk again today, I think it also has in connection with things like adoption, like you, two micro, what happened at bacardi? What is the situation with adoption? How is the pace defined? How are the standards checked? I think that is another very exciting topic which will be looked at later, so that we can come straight to the next presentation about the specs. Maybe for a moment the sun is the sun. Is it since?

A

When has it been there, but there are no dates there either, but does anyone know here in the stream or you jockey 1.2, you can figure it out. I have no idea at all. So in any case clearly, before I deal with it, that's.

B

Quite a while ago, so.

A

B

Have that I started when I was 14, we il. I started.

A

With jockey at 1 with 5, and so those were the first things. Yes, that was a big change to be followed exactly 15. I started at six and seven as I learned that I immediately did an extra one like hendrik javari has learned, but the nice thing about the spex is that these modules are not only used in jakarta. We have just seen that microsoft also uses them, but also outside of this ecosystem. Time is really used.

A

I took a screenshot from micron, auto so from a completely different java framework, which is used to build cloud native applications in java ticket where it comes to fully supporting the java, the akn notation epi, which has also been kissed since micro note, 2 4x is e.g. the jakarta point in 100% support, jack's spec and that 's just an example. There are real projects using specs from jakarta ii.

A

I think g anz classic is something like gps is now used in so many places and even outside of the server already well well, I've seen many client applications that really use something like ea or the access client software, for example, is ultimately in when it's not that often it's still ne ti. That would be the other possibility, but almost all yes, what are the web back? End frameworks are based in the java world simply on the software spec.

A

Nowadays, that's exactly what we'll look at later spex and where they are used. There is just a lot for me, or actually everything, fortunately believe in open source, but also a bit out of time from there. I would say let’s get to the next lecture right now and I’m very happy about that. I already said how I learned java ee, 6 and 7, and I really learned it through these two books, and it really is like that. So looks like that was great having german books to honor the whole thing.

A

So I'm really happy that for the author of the books we have here today.
