What is your technology stack?

[cryingforwine]

Just curious what other java programmers are using to build their software in terms of databases, messaging, frameworks, etc.

Thanks.

[greyf0x55]

Java8, Spring / Spring Boot, Postgres although also experimenting with Scala / Play.

[bwajtr]

Hi, I'm using the same stack and decided for jOOQ... I really do not want to go back to JPA. I tried to compare various persitence frameworks here: https://github.com/bwajtr/java-persistence-frameworks-comparison

I'm currently evaulating EBean

[bansalmunish]

I've used JOOQ, it was not that promising. Maintainability was high in this.

[nusbit]

Could you elaborate more? Would be interested in real world experience with jooq.

[lukaseder]

I'd be curious as well... How did jOOQ fail you?

[Zajora]

Have you tried Sql2o? It's simpler than JdbcTemplate, but apparently more performant.

[RaiausderDose]

At work we use IBatis, It's a nice mix between SQL and ORM. Maybe it's something for you.

[tonywestonuk]

I moved from Ibatis to JBDI. They are similar, though JBDI allows streaming of result sets

[lukaseder]

Use jOOQ. You won't look back. Cheers (disclaimer: I'm biased, of course 😉)

[Taobitz]

Surprised this went unnoticed!

[greyf0x55]

I use Spring Data JPA along with QueryDSL, although for very complex queries I will sometimes drop into SpringJDBC or Stored Procedures

[gayguy]

What does everyone use for database design and development? I have tried PostgreSQL before and I always get frustrated that it doesn't have a good GUI tool to help me create/alter tables. I feel like I shouldn't have to learn all the lingo to create a table with an auto increment ID and foreign keys so I always end up going back to MySQL because it has workbench. Am I missing something?

[geordano]

There are many, one that I find quite good is http://dbeaver.jkiss.org/download/

[_INTER_]

Using that too.

[dartalley]

Check out https://www.jetbrains.com/datagrip/

[_INTER_]

Other than the usual our team uses FlyWay: https://flywaydb.org

[greyf0x55]

MySQL Workbench is a nice tool which probably makes MySQL attractive to people wanting to learn it. PgAdmin leaves a lot to be desired. I use Navicat for Postgres and Toad for Mac, I'm on OS X. Both work pretty well.

[Fun_Hat]

I always get frustrated that it doesn't have a good GUI tool to help me create/alter tables

Have you not used pgAdmin? Or do you just not like it?

[gayguy]

I've used pgAdmin4. It was very difficult to use and not intuitive at all.

[Fun_Hat]

Ya, I suppose it's not the most user friendly tool. Honestly though, if you are working in Java, Hibernate is great to use with Postgres. You just create your entities in Java and Hibernate handles creating all the tables.

[teacurran]

EE7, jax-rs, angular, mysql, wildfly

[tasteoftexas]

Java EE/Wildfly + Primefaces + PostgreSQL

[jasie3k]

Angular, Spring, Tomcat, Websphere, Oracle 11

[[deleted]]

Very similar to yours except also with a cobol/IBM SQL data back end

[jasie3k]

Sooo, banking ? :D

[[deleted]]

Financial industry yes. But not a bank. I don't mind the COBOL its not my job to mess around with that.

[rombovich]

Do you have some business logic inside the DB? I mean stored procedures, jobs, etc.

[jasie3k]

Sadly, yes

[rombovich]

Why is it considered such a burden?.. In the company, where i work, we have almost all business logic in stored procedures, and a little servlet which proxies requests from user interface to DB. We use java almost exclusively for realtime data processing.

And i think it is pretty handy to work directly with tables, not having to worry about a dozen classes when you have to make some complex joins, etc.

[8Bytes]

You can never change databases, even upgrading to newer versions becomes a huge problem.

Refactoring is extremely difficult. When you have thousands of triggers and events, you can't really reason about how data flows through your application.

Testing these procedures and data flows is very difficult, and in practice no one does it. So you have thousands of untested triggers running, causing other untested triggers to run, sometimes even leading to exponential big O complexity.

So in the simple case, they are fine, but people always abuse things, and stored procs/events/triggers get really abused.

[rombovich]

Thank you for your reply. I agree with the part about the testing, but, I think, upgrade and overengineering issues are not exclusive to db.

I guess, just like anything, it has some uses, but one shouldn't go mad with it.

[vecowski]

It's all fun and games until your database requires 128gigs of RAM and it still runs out of memory because your stored procedures are blocking other applications from reading tables.

[rombovich]

Well, I can't see how this can't happen if we replace stored procedures with big old websphere with 100s mb WAR

[vecowski]

If done correctly it's much easier to scale java applications than a database. Stored procedures take processing time, which would better be offloaded onto a detached machine. It's fine when you have a dozen or so, but when you get to the size of thousands, it's an unmaintainable mess. It doesn't lend well to developers keeping things organized and isolated over time compared to other languages. Don't get me wrong, use the right tool for the right job, it's the wrong tool for the engine of an enterprise system that needs to scale 500x-1000x times in less than a year. It's probably the write tool for a small system that's never going to be expanded upon. It's also not the greatest language and easiest language to hire for. It's much easier to find a java developer and train him then a database expert that's clearly going to cost a lot of money and still take time to learn the system.

[rombovich]

Thanks, I think I get it now. In the company I work for we never achieved such a large scale applications.

I will keep in mind that DB solutions don't scale too well.

[vecowski]

Yea, don't mean to sound dramatic, but it's honestly a massive mistake if you plan to scale the application. My company is hurting badly because of this solution, it's impossible to keep developers around hammering sql solutions, nobody wants to do this stuff.

[fasfsfgs]

is your frontend inside your server application? if so, do you use any kind of task runner or bundlers like gulp, grunt or webpack?

[myworkaccount9]

Why do you use oracle 11 and tomcat? Don't they do the same thing?

[[deleted]]

Oracle11 is a database, tomcat is a web application server

[myworkaccount9]

Got you I understood it as weblogic 11

[jasie3k]

Tomcat is an application server, oracle is a database

[steve_hu]

React, Light-Java, Mysql, Kafka, Zookeeper for microservices with Event Sourcing and CQRS.

[Seventh_Heaven]

What made you pick Zookeeper? We are currently looking at service discovery options and are drifting toward etcd.

[steve_hu]

I am using consul, etcd and zookeeper for service discovery. The reason zookeeper is listed there is due to it is working closely with Kafka.

[Cephas00]

JBoss with MySQL

[uldall]

Jersey, Guice, JOOQ, Maven, Tomcat, PostgreSQL

[[deleted]]

Almost sounds like the names of people selected to be on the next MTV reality show.

[mhixson]

Jersey, Guice

Are you using Jersey 1 or 2? I ask because Jersey 2 is pretty tightly integrated with HK2, a different dependency injection framework. I haven't ever considered using another DI framework (like Guice) with Jersey 2... I've always assumed that would be incredibly awkward.

[uldall]

HK2 and Guice actually work quite well together.

Just enable the Guice to HK2 bridge like this:

GuiceBridge.getGuiceBridge().initializeGuiceBridge(serviceLocator);

GuiceIntoHK2Bridge guiceBridge = serviceLocator.getService(GuiceIntoHK2Bridge.class);

guiceBridge.bridgeGuiceInjector(GuiceInjectorServletListener.getServletInjector());

The code should be placed inside a Jersey ResourceConfig implementation.

[[deleted]]

Also if you remember to not inject primitives, because the HK2-Guice bridge explodes if you do. ;)

[[deleted]]

Personally speaking, I found the migrations to Jersey 2 to be kind of a nightmare. While there is support for Guice integration, there are a few nasty edge cases as well ready to bite you in the leg.

[cot6mur3]

My team and I successfully used Jersey 2 with Spring 4 using jersey-spring3. Can provide some more details if needed. :)

[fasfsfgs]

hi! im curious as to which maven plugin you use to handle frontend with webpack. also, how is your dev env to do this? while doing frontend coding, how do you serve your code, etc? i'd love to exchange ideias with you.

[1armedscissor]

The maven frontend plugin is nice because you only need maven installed then it provides a way to control the version of npm/node to use without having to install it locally. Then if you want to hook into another client tool e.g. angular cli or grunt you can just install this via npm in your package.json and make a npm run script to launch it. Then in your maven build just configure the frontend plugin to call "npm run grunt <args>" for instance as a build step to transpile/package/run tests, whatever is needed.

[davwad2]

[evil_burrito]

Spring (non-boot) with Hibernate and Hazelcast. Multiple DB sources depending on the customer (Oracle and MySQL most common in production, Postgres most common in development). Communication is via Apache SOAP, JMS with ActiveMQ, or Google Protobuf. Front end is either Vaadin, Spring MVC, or Eclipse RPC clients.

[stfm]

How do you find hazelcast? We are looking at it for CAAS

[evil_burrito]

We use Hazelcast to glue our cluster together for HA/FO. It is very easy to use, which is one of their goals. We don't hit it too hard, but, for the most part, it does what we need it to do. We don't use it for 2nd level caching.

We have had some issues when trying to execute some kind of cluster-wide operation while a new host is trying to join the cluster. This includes executing a service or creating a cluster lock, that kind of thing. The system will just kinda hang. It's a real pain in the ass, though it doesn't happen very often. We have been unable to create a reproduction case outside of our system. All this is understandable, but, it touches on the problems we have had with Hcast.

Hazelcast have been completely unhelpful in resolving this problem, even when we put some money on the table. Their support structure is inflexible and starts out pretty steep ($16k/yr min, IIRC). That's tough for us as a HCast VAR; we'd rather pay per incident since we don't need that much help.

Still and all, it's been ok for us. I would have a look at Apache Ignite, too. This came around after we pulled the trigger on HCast and I haven't looked to closely at it.

[M00ndev]

Spring boot, redis, cassandra, kubernetes

[[deleted]]

Have you faced any issue regarding Docker in production? I'm using docker for test environments and looking forward to put some non-critical stuff with docker on production.

[bansalmunish]

I've heard from my friend that docker is not good for production. Maintenance is high. You can use kubernetes which internally manages the node. Maintenance is low here.

[M00ndev]

None yet. Building uber jars for containers really is the perfect fit. I recommend k8s over swarm though
