Java's Evolution: Navigating Challenges and Embracing Opportunities in Software Development

After 15 years in the IT industry in Norway, Johannes Brodwall transitioned to Sri Lanka, grappling with evolving perceptions of Java. Despite loving XML’s complexities, he notes a growing disillusionment among customers who view Java as "meh." With concerns about how Oracle and other platforms are "ruining" Java, Brodwall highlights the struggles with XML, JAXB, and null pointers while parrying the complicated landscape of Java EE development decisions. This piece discusses the dichotomy between technology as a problem-solver versus a means of avoidance.

  1. Java Apocalypsenow! Johannes Brodwall Exilesoft

  2. Etter15 årserfaringfra IT bransjeniNorge, innsåJohannes Brodwall: “Deterimmarikaldt her!” Nå jobber han for IT bransjeniSri Lanka. Men erfortsattmestikaldeNorge.

  3. I love the smell of XML in the morning. It smells like… victory.

  4. Prelude:

  5. Where are the Java projects going?

  6. Maybe it is just me… … but customers: “Java = meh” … and I surprised myself by agreeing

  7. Java is my favorite language, but… … Oracle is ruining it … JBoss is ruining it … SpringSource is ruining it … you guys are ruining it

  8. «Don’t reinvent the wheel» - «Everywhere», 20XX by Everyone

  9. Part I:

  10. The nightmare

  11. XML APIs gone wild

  12. A simple XML file

  13. Parsing with DOM

  14. Whops – right this time!

  15. But the file may vary

  16. And the Java gets… worse

  17. And worse

  18. Making it worse

  19. I know!Let’s use JAXB!

  20. Just need to deal with this null pointer…

  21. And this other one…

  22. But wait – they didn’t follow the XSD!

  23. (Of course they didn’t)

  24. And we need to map it to a domain object

  25. There must be a tool for that!

  26. Running away

  27. The Java EE software development process

  28. Those that don’t Scala JSF Groovy Clojure? Those that get it JavaScript Ruby Python Clojure? “Those who cannot learn from history are doomed to repeat it.” - George Santayana

  29. Are you using technology to solve your problems?

  30. Or so that you don’t have to face your problems?

  31. … yet

  32. Part II:

  33. The dream

  34. Java’s greatest gift The IDE

  35. “I can see how TDD works for toy examples…”

  36. “… but how can we use it when we have all these really complicated technologies???”
