Hi from Riga, Latvia,
As I understand you prefer React over Angular. If I am not mistaken, you have also said that React is better because it supports more standards than Angular. I understand this argument. But I prefer Angular because it has more support for TypeScript. And I really like TypeScript.
Are there any other arguments for choosing React over Angular?
Sorry, I don't have problems with Java EE yet, it is much more simple than JavaScript development right now.

EDIT: ok, found answer myself at airhacks37 minute 30:00
EDIT 2: I have chosen vuejs.org
EDIT 3: Adam just spoke in Devoxx about this https://www.youtube.com/watch?v=tgpruknOOfE

Hi Adam

I read that you are a member of the JSR-375 (Java EE Security API) expert group. Does this API help protecting REST endpoints of Java EE 8 applications?

Hi Adam,

I am trying to understand the reactive programming concepts and would like to know your opinion about the following:

1. There are so many frameworks like: CompletableFuture, RxJava, Reactive Streams, Akka, Vert.X, ReactJS, ...
   I am a bit confused which one to use, where to use... What do you think about these technologies ? Do you use them, if so in which situation which one, what are your advice's ?

2. I still cannot see the advantage of RxJava against CompletableFuture of java 8. Seen the fact that I cannot return an Observable from one JVM to another, I don't really see a huge difference/advantage except the possibility to signal the end of a stream or returning an exception on a better way. Do I miss something ?

Thanks

Hi, Adam.

1. I tried to call an @Aynchronous Ejb method containing a long running process from a @startup @singleton Ejb. I expected that this method will not block the Application Start because of the async nature, but does. Am I doing sth wrong here?

2. Is it possible to use @PersistenceContext in an @interceptor annotated at an Ejb? Or in other words: is it possible to make an Interceptor @stateless and use JPA? Payara seems to have a problem with that....

3. Do you have any experience with AMQP (rabbitMQ,apache qpid) for transferring data asynchronously? Is it useful for sending masses of datasets between microservices in a scalable and reliable way?

Thank you :)

Possible to unit test primefaces? Possible to develop an independent primefaces based project then use it w/ backend Javaee later?

Hi Adam,
I want to use JAX-RS 2.0 client (using Jersey) in a JAVA SE 7 multi-threaded environment project.
How can I make the client instance thread safe so I can reuse it?

Thanks,
Eyal

Hi Adam!

• any workshop (streaming/vod) update ?
• proper and by standard way implementation attachments in JAX-RS?

Hi Adam,

thank you for all the wonderful work that you do!

Can you please comment on the differences between Java EE and C#/.NET ? If you change from one platform to another, how much of your knowledge would transfer? Would the change be something like Java EE -> Node.js or something like Java EE -> Spring?

Thank you,
Nejc

Hi Adam

1- Have you already used dynamic entity in eclipseLink , and what's your opinion about using it in a production project with large amount of data ?
2- I work with sensitive data, so what is the best way to encrypt data.
3- working offline is Is a much-needed feature, how can I implement it and synchronize data once Im online.
4- Can you share with us a completed project in Github like Arun Gupta's Miles2Run or Cargo Tracker, so we can take it like best practices project.

thanks

Hi Adam,
Which conferences do you advice to see the trends of software industry and get the best benefit (no fluff just staff)?
Thanks

Hey Adam!

Which would be your approach to implement SSR on a custom SPA (ES6) in JavaEE ecosystem ?

I want to avoid jsp.

Thank you!

Hi Adam

I would like to know how you naming your boundary class which just consist of create, read, update, and delete (CRUD) action? I want to avoid something like xxxService or xxxManager in naming class but more and more I will have a class with CRUD responsibility.

Thanks,

Hi Adam,
Just found http://openjdk.java.net/jeps/264 for Java 9. As non goal "no standard log interface" is mentioned by referring to java.util logging methods. I think the java.util logger has enough methods for normal projects.

I'm tired of these logging framework debattes.

Within this JEP you have the contract that the Java Logger outputs can be delegated to Log4j etc.. Your thoughts ? I would stick with plain Java before using libaries.

Greetings from Munich.

Hello Adam

I would value your thoughts on Auto Discovering RESTful web services and/or developing a Generic RESTful web service Client.
I would really like to develop a repeatable process where I could periodically auto discover all existing RESTful web services end points with their associated Request/Response structures.

Warm Regards

Andy

Hello Adam,

1- I want to learn React js / Polymer with a java ee backend , can you show me a good sample project to start with .
2- What do you think about performance of streams api in Java 8 ? and do you think that oracle team will fix the gab of performance between streams and loops ?

Thanks

Hi Adam,
I am testing HA in glassfish/payara (no hazelcast). I would like to make web session replication working. Do you have any suggestions?
It seems that sessionid is always refreshed and never shared.
Thanks.

Hi Adam,

I am very interested and excited about the concept of a fat-jar. Therefore my question: Is WildFly Swarm Production ready? Especially when it comes to future support etc ...

Thanks

Me again :) You often recommend Kubernetes to use for JavaEE Microservices. Is it possible to make a (maybe seperate) Youtube Coding Session which covers Autoscaling, Service Discovery, Fault Tolerance and Load Balancing with Kubernetes? Maybe Openshift is also an Option? This would be great.

One more, is there any way to set Timeout in JAX-RS using only JEE or something that works in Jersey and Resteasy?
Thank you!

Hi adam,
How do you see java based frontend like jsp and jsf compared to javascript based ones with javaEE backend? How do you see the future of each and what do you recommend to dive in?
Thank you.
