javaee-to-quarkus

A migration guide and workflow for moving Java EE 7 or 8 applications from servers such as WebLogic, JBoss, or WildFly to Quarkus 3. Quarkus is a Java runtime that can run the application without a traditional application server.

In plain words
What is it for?
Use it to convert server-dependent Java EE applications into standalone Quarkus applications.
Why use it?
It covers the application changes needed beyond renaming Java package names, including configuration, packaging, dependency injection, messaging, and persistence.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

javaee-to-quarkus scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Java EE 7/8 to Quarkus 3 Migration

Prerequisite: Ensure your application compiles on Java EE before starting. Java 17 is the minimum JDK for Quarkus 3.

This migration goes beyond a javax-to-jakarta namespace rename. It replaces the Java EE programming model with Quarkus: EJB → CDI managed beans, JMS/MDB → SmallRye Reactive Messaging, WAR → JAR packaging, persistence.xml → application.properties, JNDI lookups → direct injection, and app server lifecycle hooks → Quarkus lifecycle events. The result is a standalone Quarkus application with no application server dependency.

Phases

Execute in order. After each phase, run the project build and stop if it fails.

  1. Build Config — Restructure pom.xml: WAR→JAR, add Quarkus BOM and plugin, replace Java EE dependencies with Quarkus extensions. See modules/build-config.md.
  2. App Config — Replace persistence.xml with application.properties, remove web.xml and beans.xml. See modules/app-config.md.
  3. EJB to CDI — Replace EJB annotations with CDI, remove Remote/Local interfaces, replace JNDI lookups with injection. See modules/ejb-to-cdi.md.
  4. Messaging — Convert MDB classes to SmallRye Reactive Messaging, replace JMS producers with Emitter. See modules/messaging.md.
  5. Lifecycle — Replace server-specific lifecycle listeners with Quarkus startup/shutdown events. See modules/lifecycle.md.
  6. Cleanup — Delete legacy files, remove weblogic/jboss stubs, verify no javax.* EE imports remain. See modules/cleanup.md.

How to use

Load each phase's module when starting that phase. Each module contains before/after code examples and references mapping tables in references/. Apply every applicable transformation to the codebase.

Build gate

After completing each phase:

  1. Detect the project's build tool (check metadata build_tool field above, or detect from project files: pom.xml → mvn compile)
  2. Run the build
  3. If it fails, fix the issue before proceeding
  4. If you cannot fix it, stop and report to the user

What ships with it

12 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
