I like Javalin and try to get the Hello World going. According to the doc only javalin-2.5.0.jar is sufficient.

However, when I run the example I get the error:

run:
Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
	at io.javalin.Javalin.<clinit>(Javalin.java:54)

I added slf4j-simple-1.7.25.jar to the CLASSPATH, but this did not make any difference.

Hello,

I am interested in contributing to the translation of site documentation to Spanish. Do you think we can start that project?

Sorry! My mistakes.

Currently javalin.io provides only OpenGraph tags, would be nice if someone would implement tags for Twitter:

• https://developer.twitter.com/en/docs/twitter-for-websites/cards/overview/markup

Thanks for doing this, @richarddd !

I added a "Who's using Javalin?" section on the webpage. The initial list is based on publicly available information from GitHub/Gitlab, Maven, and user websites.

If you want your company added to the list, please comment on this issue.

Heroku will stop offering a free tier starting 2022-11-28.

Starting October 26, 2022, we will begin deleting inactive accounts and associated storage for accounts that have been inactive for over a year.

Starting November 28, 2022, we plan to stop offering free product plans and plan to start shutting down free dynos and data services. We will be sending out a series of email communications to affected users.

Our Heroku tutorial should be migrated to a different provider, ideally not requiring a credit card for easier testing for people without one or those who do not want to provide their credit card.

In the Kotlin tutorial about "Integration testing with khttp" the Github repository link to a Python example, no Kotlin, no Javalin. I did not find the proper repo on Google to create a Pull request.

We're very pleased to be able to sponsor Javalin. We've just finished converting our app from Spark to Javalin.

The sponsorship is from my company, Barbary Software. However, we'd prefer the logo to be that of our main product, Feature Upvote.

Name: Feature Upvote
URL: https://featureupvote.com/
Logo: Our logos are here. You can select the one that works best for you.

Let me know if you need more info.

I suspect the problem here may be related to my particular configuration, but the handler groups example code fails to compile for me. The name app methods like path and get and post are not found, it does not seem to reference an implicit `app.

I'm using the JDK for Java 8, does this code depend on a newer version of Java?

Hi!

Javalin seems very interesting and I would like to learn more about it.

I am quite to programming (work in engineering) and APIs. It would be nice to have a very simple (for beginners with only the very basics of programming) Java-based tutorial of how to use Javalin. I think the tutorials are great but quite complex for complete dummies.

For example, a small Java-program that reads the temperature in London (or any other information) of one website and prints it to the screen. Just something I could copy and paste directly in Eclipse and run it. In this way, I could get an easy start with Javalin.

I think such example would help many newcomers to start with Javalin.

Thank you very much!

Current one is aimed at Java devs and was written the first day I tried out Kotlin. We should make one that's more to the point, just for Kotlin users. Rename the old one to "Kotlin for Java developers" or something.

javalin is great, what's the recommand way to connect to database?

Currently, when we're browsing site, we don't know which page is selected from the menu:

Would be nice if selected page had some indicator, like e.g.:

In the Javalin 3 to 4 migration guide, it mentions that the Context extension methods Context#register and Context#use have been removed but provides no information on how to migrate code that depends on these methods.

https://github.com/javalin/javalin.github.io/blob/master/pages/docs/migration-guide-3-4.md

Please add this information to the documentation.

The description property is currently missing. See the OpenApiParam annotation for comparison.

In the Java sample code of configuration section, all config options miss the semicolon.

I asked /nickm_27 on redddit if he could write a Raspberry Pi tutorial, to which he agreed (comment) 🎉

This issue exists for asking questions about how to work on the tutorial.

In general, adding tutorials to Javalin is done by adding a file in https://github.com/javalin/javalin.github.io/tree/master/_posts/tutorials

If you want to run the project locally, you need to set up Jekyll: https://jekyllrb.com/docs/

I see there are function about Session in the Context, but it is not clear to me how you would create a session, store/retrieve data from the user session, delete the session, renew the session, expire ...

By the way, is there a user group like a Google Group or else ??? or Github issue is THE user group ?
Thanks

[This issue is more of a reference of the one I made on the main Javalin Repo, it's just that this one's on the right place now, see this]

Currently what we have with the docs are two separated categories for the tutorials, one for Java and one for Kotlin:

I think it would be best if we only had one column that tackles each topic separately, but includes both the "Java" and "Kotlin" version on the same page.

Something like this one that toggles the code snippet into the version chosen by the user. This way, users who prefer a certain flavor can easily have access to tutorials that are fitted to what they currently know. Although Kotlin and Java do share a lot of similarities with each other, it would be nice to ease the burden to new users of the framework of having to learn and understand the other, just to be able to try things out. 😄

1. Set "Properties > Resource > Text file encoding " to UTF-8
2. Set the "properties" of "project.build.sourceEncoding", "maven.compiler.encoding" to UTF-8, in pom.xml
   
   <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
   <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
   <maven.compiler.encoding>UTF-8</maven.compiler.encoding>
   

Still can not display the Chinese word?

Describe the bug

Ruby dev. New to Kotlin. Prototyping business need.
Using Intellij created a new Kotlin project using Gradle build with starting code.
Cut & Pasted the Javalin dependency for Gradle as described in Getting Started.
Received formatting errors from Intellij IDE.
Seems i needed to format as: implementation ("io.javalin:javalin-bundle:4.6.4")

Being my first Kotlin project (ok 2nd after hello world), maybe something i did setting project options (yes it was)?
Don't know if anyone else may hit this issue and if new to Gradle (like me) might get stuck for a few.

P.S. (added later) I just noticed/learned that u show the Groovy Gradle format. And i am using the Kotlin Gradle format. So i changed the title of this.

Coming from Ruby/Sinatra, like what i see in docs... thx...

Hello,

This was a small frustration I had following the tutorial, no explicit mention of what imports were required to remove errors when building the project. I went to the source code to fix the problem, but intellij did not know where to import the get/post/patch methods from!

It may make it easier for other beginners to test the project.

@bchristenson has made a nice async example (https://github.com/bchristenson/example-cassandra-javalin-rest-java). Maybe he could be convinced to publish a tutorial on javalin.io ?

@barbarysoftware thank you for your donation! Since you're on the $50 tier, you can have your logo present in the "Sponsors" section of the https://javalin.io, as well as a link to your website. Currently, this section doesn't exist (since you're the first $50 sponsor), but if you add your logo/link to this issue, I will create a section for it on the website :)

There is no mention of some methods being impossible to document in 3.x when using Java.

This issue is to track the documentation of these issues.

This PR helps with the issue but I would love to see some docs: javalin/javalin#1162 (this is for 4.0)

Set header to pos abs and scroll inside a div instead.
