A

Okay, we're live and welcome to studio, jakarta e, and uh in this interview I have with me, uh werner kyle, welcome burner hi welcome.

A

So uh please tell us a little bit about yourself and how you're involved in the jakarta e community.

B

Yeah, I'm I'm involved in several eclipse projects on several layers for a client, mostly during my day, job, it's actually more on the ui front, with eclipse rcp and in the chicago e community. I help the community, as the committee representative in the spec committee, for I think it's the third year now. Actually that started.

A

Yeah you're actually elected there, for you win the election every year.

B

So at least, I think it's the second or fourth re-election that took place.

A

And and you were uh pretty active in the jakarta platform project as well and with the jakarta e9 release, and what do you think is the most important thing with the jakarta nine.

B

Well that it's open and transparent, uh it's especially helpful it also.

B

There was, I think, uh two or three days ago here in in germany was a day celebrating uh volunteer activities, the ian amped and there I basically mentioned that uh contributing to open source is also a sort of an armed, and especially, of course in serving in the spec committee or in in a similar working group. It's pretty similar to to an armed in. I don't know, let's say for here for germany, comparing it to a fascinating that hosts the carnival every year.

A

B

You look at the.

A

Jakarta e as a carnival.

B

No, but it's a voluntary activity that people dedicate a lot of time and in most cases except maybe for the expenses they also usually don't get payment, uh for example, in those carnival communities, they may get a lot of free beer, but usually they don't get money.

B

A

There's nothing such thing as free. Very you know.

B

A

The contribution is.

B

A little comparable and, of course uh there are more people who now are able to contribute and also help shape the community, but again with some of the larger vendors, including oracle, stepping a little back and doing less on their side.

B

It of course means that you also need regular activity and I'm not going to mention names, but if some of the other working group members in various committees either don't even run for the election, as we saw, I think in the marketing committee, where yeah I can't, I can't run in every single one of them uh and aryan and a few others can also run in multiple of them, because we have several other responsibilities in in the platform project or in detailed projects like security and a few others and for the marketing committee.

B

It seems that it was not so appealing.

B

I understand it because it may not be everybody's uh preferred activity unless you you work in the marketing department as your day job, but if either nobody volunteers and the seat is not filled or if the others who got elected have too many conflicting activities elsewhere and they cannot contribute or they cannot join the cause for over six months. In some cases, then, of course, uh in the worst case, that may even mean that some decisions cannot be made if there's not a quorum.

B

Luckily, we are not so often in that situation, maybe in the holiday season it might happen, but otherwise I think we never lost a quorum. But of course uh that means if, if another, let's say community related representative is not able to participate, then that means the community only has one voice instead of two.

A

B

Is yeah? That's a good point.

A

Yeah, that's a very good point. So if you, if you do run in an election and sign up for this engagement, it's actually an obligation to be there an obligation to the community, not not not necessarily to the working group but for the community.

B

A

Yeah and but there are other ways of contributing than than being a member of these committees, and and that is the the groups where, let's call it, the real work is done like in the specification projects yeah so and, and you regularly uh participate in the platform, call as well and.

B

A

Weekly calls there that is open for everybody, so.

B

I I try it's also a little easier now uh with the home office situation, because if I'm at a client on site, then it may not always be possible due to their own security restrictions to dial using some other network than their own.

B

But at least, if you have a second screen that makes it a little easier to spare an hour or two a week.

A

A

You participated, as you said, in in jakarta. E9, do you have any features that you would like to see in upcoming releases? No, the the 9.1 release is pretty much.

B

Set what it will, I'm not sure if 9.1 uh it may be a little too early for 9.1, but there's of course, uh no sequel or mvc that are ramping up and in some cases also releasing especially uh mvc has an upcoming 2.0 release. So I'm not sure if it's acceptable for 9.1 and I'm a little bit skeptical, because.

A

B

uh In my opinion, it should have some sort of reform of the profiles that you don't just stuff it into the web profile as yet another feature, but probably try to diversify a little and have whatever you call it.

A

B

It micro profile, because the name started with that idea- sure why not.

A

B

If a different term is better at least not to confuse it with eclipse microprofile, then maybe we'll find another one, but there should be a profile, for example, that relies more on the on the rest, plus mvc stack, where implementers are, for example, not forced to also implement the whole servlet stack in parallel, because the two of them are somewhat competing and if a if a particular solution wants to be a little smaller and focus on rest apis, but still have some uh simple ui based on mvc, then they can basically abandon uh servlets and faceless and jsp and all the other stuff.

B

But that would require a new profile. That's a little similar but lighter and slightly different to the web profile, because I believe rest is part of the web profile. But basically you don't need all the servlet stack to run mvc on top of rest. So it could be a lighter version of the web profile. Yeah.

A

Whatever it's interesting, it's interesting that you mentioned it, because this was actually a topic in the round table earlier today as well, but but there it was more about creating a an entirely ui free profile, more of a headless profile or or a nano micro or micro micro yeah. So that also makes sense and- and maybe maybe you can have finer granularity, so you have one headless, maybe with cdi light, even yeah that is very small and and then a little bit bigger, you add mvc and then even bigger.

A

You have servlets and and face lights. So you kind of have it.

B

Yeah, that kind of modular profile and with modular some of it may actually also benefit from the java platform module system that, in nine several almost all the specs were actually able to support, at least in a basic form, but some of them didn't have enough time to do that. So I think that's. What probably we should do in 9.1 is to make sure that all of them do so. It's also a little easier to then combine and compose modules that consume other modules.

B

And this way it should be a lot easier to have those kinds of profiles. uh I'm not sure if javasc really still calls them profiles, but there sometimes. You can also combine what you want with jailing and literally have a jdk of your choice and completely leave swing away or completely lift well uh java. Fx is not even part of the jdk, but you could have one that has no swing, and then you add uh java, fx or openshift x.

B

On top of that, so you can do something similar in java s e, and I guess in that direction uh what you mentioned with a stacked or a very small profile. That then has a few optional modules uh would allow something very similar for jakarta.

A

Yeah so uh you're involved in in, as we talked about in in the spec committee and you're in the platform project and in several other of the specifications as well.

A

Why do you think people should get engaged in the jicarillae community? How does that help you in your daily work.

B

Well, for example, in the previous client uh that was a lot about security and securing the e-health.

B

We also have another talk about that tomorrow by the way- and uh some of it uh also is some aspect of a book that ariane and fellow jakarta, ee, ambassador, todori, spice and myself are working on in the next couple of months, so we hope most of us will take a little time over the christmas holidays when some have a little more time of their day shops.

B

So we expect the book sometime in the first half of next year and some of it, especially on the java se side or the changes that were necessary to to make soap still work in java 11..

B

They are actually related to jakarta ee. So, with some of the clients, uh I usually end up using that experience in the current one. It may not always be completely my responsibility to deal on the back-end side, because there are other teams that do it and I'm consuming it, but even there we are using a lot of soap and should we ever upgrade from java se8 to 11 or above then.

B

Of course, we need to use jakarta ee, so it's quite natural having to use it, and that, of course uh is beneficial when you're way close to those who shape the community or even help ship, some of it yourself yeah and I'm not getting paid uh for the amped. But in some cases uh I know.

B

For example, uh there was a another banking customers, if customer a few years ago, and they were also the observers of the java money, api and one of the gsrs that I'm leading that among the very few that have not gone to check out the ee, but there I also lead two of those and in that particular case, they they were contributing or at least observing and participating in java money, and they also subscribe to the mailing list.

B

And unfortunately, due to budget constraints, the customer was not allowed to actually uh get new people on board, but when we were discussing it they they were very keen to get me on board and they said in most cases we want people uh to fly into switzerland and meet us in person and then maybe uh do some code puzzle. But we know what you have done to with the java money project all those years. So you don't have to do that. We would hire you straight away if we are allowed to yeah.

A

So being a part of specifying the technology you work with in the daily life is a good way of getting job. So with that note, I our time is up, so we have to close this session and everybody else can go to the next session, which will be a uh session by ad burns and emily young. They will uh transfer a spring boot application to micro profile. So that's that will be interesting. So thank you very much we'll meet again.

B

Okay, then, thanks for inviting me and have a good rest of the evening and see you.
