where do you use Java? Take a minute before taking Java cert.

I started working with Java in set top box development environment and maintaining one JSR. But recent years, not using Java at all.

So my experience with Java is all in embedded system. CE device.

Hope guys, we can share on these realistic questions:

Can we all share something about our Java work experience?

Where do you use Java/JEE? Do you work at a bank? Do you use Java to develop big enterprise system for big enterprise?

Is Java bringing you great wealth?

Do you find Java is expanding or shrinking around you?

What's your enterprise's attitude towards Java solution compared with other options?

The success of Java is mainly in server-side software, running on big enterprise servers of a lot of companies all over the world.

I've been working as a Java software developer for the past 10+ years and I've worked for a number of different companies in different sectors, for example in the telecom, energy and transport industries. All those projects were for enterprise software running on big servers, and the software varied from web applications to mission-critical, high-performance middleware systems (i.e. systems without a GUI, processing data using databases and messaging) and also a large desktop application (using a Swing GUI).

I've been working as a freelancer since the beginning of 2009 and I haven't been out of work since I started for myself, despite the economic crisis. I did notice that the rates that companies are willing to pay have dropped in the past year, however. Still, I make a nice amount of money as an experienced Java developer.

I don't see the popularity of Java going down, Java developers are still in demand and I expect it to be that way for the forseeable future.

About your last question: Obviously I work at companies that have chosen to use Java. The Java world and for example the Microsoft .NET world seem to be quite separated. I see Java being used everywhere and don't encounter many .NET users, but I recently met a few .NET developers and they were asking me the opposite thing (why they only see .NET jobs and only few Java jobs).

It is best to use caution when sharing personal information on the Internet. A good guide it to share only what you would share with a complete stranger.

I was a mechanical engineer till 1999. Changed my career to Java in 1999. Started contracting since 2002. To date never had trouble finding contracts. Java is used in various sectors like finance, insurance, telecom, retail, government, etc. It is predominantly used for

-- Building SOA based services.
-- Building Web applications
-- Integration via MQSeries, Webmethods, etc.

Newer systems are built with databases like Oracle, DB2, SQLServer, Sybase, etc. Older mainframe systems can be Web enabled using Java and message oriented middle-ware like MQSeries, WebMethods, TIBCO, etc. I have worked on a number of large enterprise projects.

Moving from being a mechanical engineer to a Java developer is the best decision I have ever made in my career. Engineering skills have certainly helped me a lot. I guess, I got into it at the right time.

Many companies have invested lots of money in Java, and I agree with Jesper.

I think it would be waste of time to debate on this topic. Open a job site and search for java jobs. It will give answer.

Thanks, Jesper, your Java experience much richer than mine. thanks for sharing it.
Both .net and Java have spacious market, on individual developer level, one may easily neglect the other. And I hope profit-driven Oracle will not cut funding on Java evolvement.

don't worry that much, at least it's mutual, we need be careful with what a stranger share with us.

Good experience and good decision !
From you and Jesper, it seems not hard/common to find freelance and outsourcing jobs with Java, and with large companies. Good luck!

Nice cheering up.
I am early with my Journey as well, although having worked for 6 years, only 2-3 is with Java. And only in embedded device, not a good start for me.

let's hear what people subjectively say beyond objective numbers.

well, it's a Java forum, can't hear much of a opposite voice.

Dont rate technologies of languages based on the number of jobs offered, those jobs are the number of empty desks, you are forgetting to count the people which are already employed in some other technology.

If you can provide me some data like in according to xyz article n1 empty desks on java, n2 employed in other technologies, I would be happy to discuss further. I would not like to discuss just on assumptions or emotions.
