Why is Java so popular in enterprise?
replies(12):
And Oracle (well before the Sun acquisition - in fact, control of Java was basically the main cause of that move).
Any technology that could bag both IBM and Oracle is (or rather was) likely to dominate the enterprise space.
Microsoft had C#, at one point IBM pushed SmallTalk. C++ for these environments is doable but going to slow you down at development a lot, as well as being much harder to secure.
At that time the dynamic alternative was Perl, and that remained true basically until Rails came along.
In the late 90s, I got stuck making a scheduling program in Java, but it had to run on the 16-bit Windows systems of the time. That was a huge pain, because the 16-bit version didn't have all the capabilities that management was expecting based on the hype. These days, I sometimes have to install enormous enterprise applications that tie up north of 32G of RAM even though they're just basic hardware management tools that would take a fraction of that if built in something like C++ with a standard GUI library. I manage to avoid Java most of the time, but it's been an occasional thorn in my side for 30 years.
I would say that many things in IT are not chosen on technical merits alone. You have people that do not want to accrue any blame. Back then, by choosing what IBM endorses or what Microsoft endorses, you absolve yourself of fallout from if and when things go wrong.
Back in the 90s, it felt like IBM, Redhat, Sun kind of, sort of, got together and wanted to keep Microsoft from taking over the Enterprise space by offering Java solutions.
Of course those were much more hazardous languages than Java.
