Update Java and CORS template docs

[welteki]

Description

Update the Java OpenJDK 11 tutorial to state that the templates use Eclipse Temurin on Ubuntu 24.04 Noble, and replace the removed Gradle compile dependency configuration with implementation.

Refresh the CORS post with current HTTP template names: replace Node 12 with Node 26, retain the supported golang-http and golang-middleware templates, and update the Python and .NET template names. Retain java11-vert-x and ruby-http.

Motivation and Context

This documentation update accompanies openfaas/templates#321 and openfaas/templates#319. The Java templates are moving away from removed OpenJDK image tags, and the affected website content needs to reflect the current images, Gradle syntax, and HTTP templates.

Have you applied the editorial and style guide to your post?

Yes.

How have you tested the instructions for any tutorial steps?

Verified the image names and Gradle version against the templates change, checked the CORS template names against the upstream template repositories and template store, and ran git diff --check.

Summary

• Documentation-only PR updating Java OpenJDK 11 tutorial content, Java landing-page sample code, and CORS template names.
• The Java examples mostly align with the newer handler base class and java11-vert-x naming.
• The CORS template list is refreshed to current template names.
• One Java tutorial dependency snippet still uses the removed Gradle compile configuration, which undercuts the stated migration goal.

Approval rating (1-10)

7/10. The scope is useful, but the Java tutorial still contains a dependency syntax regression that can break readers following the updated steps.

Summary per file

Summary per file

File path	Summary
_includes/landing-page/code-examples/java.html	Updates Java sample to extend AbstractHandler.
_posts/2020-01-30-get-started-with-java-openjdk11.md	Refreshes Java tutorial images, APIs, commands, examples, and links.
_posts/2020-04-08-function-cors.md	Updates CORS-compatible template names.

Overall Assessment

The PR moves stale documentation in the right direction and fixes several outdated references. However, the updated Java tutorial still tells readers to add OkHttp dependencies with Gradle's removed compile configuration, while the PR's purpose is explicitly to replace that syntax. That is a concrete reproducibility issue for the primary tutorial path and should be fixed before merge.

Medium: Java tutorial still uses removed Gradle compile configuration for OkHttp dependencies

In _posts/2020-01-30-get-started-with-java-openjdk11.md lines 152-159, the tutorial says to keep the template dependencies and add:

compile 'com.squareup.okhttp3:okhttp:3.10.0'
compile 'com.squareup.okio:okio:1.14.1'

This is the same removed Gradle configuration the PR description says it is replacing. The later Vert.x dependency snippet was updated to implementation, so readers following Example 1 can still hit a Gradle configuration failure or copy outdated syntax into the refreshed Java 11 template. Use implementation for both OkHttp dependencies:

implementation 'com.squareup.okhttp3:okhttp:3.10.0'
implementation 'com.squareup.okio:okio:1.14.1'

The title and excerpt still match the article's scope: getting started with Java 11 and Vert.x on OpenFaaS. The opening clearly explains the image and dependency-source changes. The Example 1 flow is otherwise coherent after switching from QuoteGarden to DummyJSON, and the CORS article's changed section is concise and limited to template-name maintenance.

The blog post is correct the Java11 template uses an older Gradle version. Question is if the template should be modernized.

[alexellis]

A newer Java template is worth creating - but I would imagine it'd be vert-x only not Java 11 which is very old at this point.

Java 21 runs to at least September 2028. Java 25 is now the current LTS

That'd be a new template, triaged on Trello and managed properly, with updated/latest vert-x patterns and version. Gradle again too - but updated.
