Oh we have JBOSS in our stack, it’s what handles our service bus. I’d rather we didn’t though, it’s really hard to find JBOSS developers/maintainers for public sector pay checks.
We used to see a lot more of it from our suppliers, but it seems to be rapidly going extinct. Possible because there just aren’t a lot of JBOSS developers/maintainers in general.
I am coloured by my environment of course, but I do work in software cooperatives with 97 other muniplacities, as well as a few European communities and I don’t see anything to indicate that .Net, JAVA and PHP won’t remain the dominant techs in Europe for the foreseeable future.
I like node.js, I use it for hobby projects and I genuinely think graphql is a lot better than rest APIs (and there isn’t a graphql adaptation for .Net that isn’t bad), but I just don’t see the adoption anywhere outside of what you hear from American startups.
And again, I didn’t say .Net would rule all web development , I said it would be important, and if the European public sector continues to run on .Net then it’ll continue to be a billion dollar industry.
