Senior Legacy Java EE Developer (JBoss 4 / EJB 2.x / XDoclet)

I'm looking for a senior Java developer with genuine legacy Java EE experience to help reverse-engineer and maintain a production JBoss 4.0.5 / EJB 2.1 / XDoclet system.

This is not a Spring Boot role. It's for someone comfortable working in pre-annotation Java EE environments.

Must-have experience

• Java EE 1.4 / 5.0 era systems
• JBoss 4.x (or WebLogic 8/9, WebSphere 5/6)
• EJB 2.1 (CMP/BMP, Session Beans, EJB-QL)
• XDoclet 1.2.x (understanding + debugging code generation)
• Ant builds, legacy deployment descriptors
• MySQL 5.x, JDBC, JNDI

What you'll do

• Reverse-engineer and document an existing system
• Understand XDoclet-generated EJBs and mappings
• Fix issues, make small enhancements
• Provide clear documentation / knowledge transfer
• Advise on safe, gradual modernization (no rewrite)

Practical details

• Remote OK
• 3–6 month initial engagement
• Contract or consulting preferred
• Sensible rates for rare legacy skills

Please don't apply if

• Your experience is only Spring Boot / Jakarta EE
• You've never worked with EJB 2.x or XDoclet
• You've only used modern WildFly / EAP

If you've maintained or untangled real legacy Java EE systems, I'd like to hear from you.

• Message me directly with specific examples of similar work.
