Too (many?) Java technologies. Where to start?

yeah, that's why after i save enough money i'm thinking of going back to school and learn a skill that doesn't require a corporate life. IT is designated as the 4th most depressing job in a list of 40. Ang hairdresser ug embalmer naa gud sa top 5 most satisfying. Maypa kana nalang ako skwelahan.

bro to comment sad about the quote about what that scientist stated above, siguro I would say I can agree that it would add more complexity but from my experience, Generics has served me well so far and haven't experience difficulty in maintaining and experienced any error prone situations caused by Generics.

but anyway, since that person could have a hell of a lot of experience in software development more than I do, then I'll give him credit for those things he said and that would make me more aware about it.

In understanding languages and knowing what's best and how to use them, we should also consider that, for example with Java, the people who designed it, those designers from Sun, also are faced by deadlines. Although they are very experienced and wouldn't be there if they sucked, they are also human and prone to design errors. They also face pressure, fatigue, stress, etc... And this goes the same to other languages.

That's why it's best that we should familiarize ourselves with the libraries of our language. If I'm using Java, then I should open the API that I need to use and understand its design as much as possible so I would how to use it best and what to avoid.

Anyway, I've read that Sun is planning to open-source Java. I don't know if this is already the open JDK available now, but if this be the case then Java will greatly improve in many areas.

here's my suggested roadmap if you like to be a serverside developer.

1) study core java
2) practice using java.lang, java.util, java.io, java.text and java.sql classes
3) practice connecting to database using jdbc/java*.sql api; you should familiar with sql
4) study servlet; download tomcat as a web container
5) practice jsp; then understand how to do MVC using jsp and servlet.
6) Be a hard core in SQL; sirko-balentong sa joins and sql operations
7) play around with struts, connecting to database using jdbc using connection pooling
then play around with hibernate; understand what does it do
9) play around spring; memorize inversion of control and dependency injection patterns
10) Repeat 1 to 9 until you you can create a blogger web app using tomcat/hibernate/struts/mysql. The time line of this endeavor depends on your IQ and patience. So kugi lang ang secreto and eat plenty of protein and vegetables.
11) once you have mastered them, update your resume, ace the interview, and ask not less than 60k/month. If you're veteran programmer, it's easy to get 80k.

if you cant survive corporate, i am afraid your option will be limited to start ups (lots of them are questionable cos who haggles your salary). Programmers nowadays are consultants who talk to customers and most likely who will adhere corporate standards.

1) study core java. DONE
2) practice using java.lang, java.util, java.io, java.text and java.sql classes murag DONE
3) practice connecting to database using jdbc/java*.sql api; you should familiar with sql. I just know this in theory but I can use my book for reference lang.
4) study servlet; download tomcat as a web container Jboss, Tomcat, glassfish, Sun App Server, Oracle AS 10g. I wasn't always a developer you know.
5) practice jsp; then understand how to do MVC using jsp and servlet. DONE
6) Be a hard core in SQL; sirko-balentong sa joins and sql operations Sos MASTER kaayo ni nako!
7) play around with struts, connecting to database using jdbc using connection pooling Wa pa kaayo ko naka apply ani but I understand the concept
then play around with hibernate; understand what does it do NOT DONE
9) play around spring; memorize inversion of control and dependency injection patterns NOT DONE
10) Repeat 1 to 9 until you you can create a blogger web app using tomcat/hibernate/struts/mysql. The time line of this endeavor depends on your IQ and patience. So kugi lang ang secreto and eat plenty of protein and vegetables. Yo forgot to add the fact that each time you keep doing this, the development time should continue to decrease as you gain better knowledge.
11) once you have mastered them, update your resume, ace the interview, and ask not less than 60k/month. If you're veteran programmer, it's easy to get 80k.

@maddox: Thanks kaau sa imong codes sa java bay. Nice kaau pagka-explain. Study pa ko og maau sa JEE 5.

focus is the key tokidoki. You dont need plenty of application servers. It's easy to change web containers if you know the basic.
I can migrate my apps to an app server in less than a day (conservative duration).

an exercise tokidoki, how do you do MVC using servlet/jsp?

Umm using struts or JSF? hehehe... wala ko hands-on ana bai. only the idea.

[CmdrAdobo]

You dont need struts, jsf or insert any framework to do MVC.

@cen

sorry wala nako naka-follow up sa ato project bai. got busy lately and sick.

anyway, let's just keep in touch. thanks!
