Can you take then and use them with something else where you just need HTTP/S and no servlet API? Not easily. Are they portable? Yes, they are as portable as Java is. Are they modular? The classes are all in a single JAR but it is structured so it easy to extend with new implementations. Tomcat uses JSSE for TLS. When using OpenSSL, it is wrapped so it looks like a JSSE implementation.

That sounds insane. We would simply do without. I'd sooner put my old mobile phones into service supporting my applications than an old i486.

Why are we still paying so much for phone service? Because we (presumably; I do) live in the US. Elsewhere in the world, it's much better. We are being charged high rates simply because we fail to refuse to do so. Why aren't our high school grads capable of re-soldering components from these old boards and assembling them into something better and rewriting the software? Some of them are, but most of them are not. It takes knowledge and skill and desire. Soldering boards isn't on the top-ten list of most graduating high-school seniors.

I use Ubuntu for my various test environments and the servers I run at home. Stuff I know well (Tomcat, Java, etc) I tend to install manually rather than using the package manager. +1000 for Ubuntu. Many years ago I used and loved Debian. I have found that Ubuntu retains all the things I love about Debian but has a much larger selection of packages available, due to Debian's strict adherence to only including software that meets DFSG requirements. I mostly use Ubuntu packages, and in some cases official project repos for Ubuntu (gitlab, zabbix, dovecot, etc), but there a few things that I prefer to use official downloads or source to install. Solr and haproxy are the top two in that category. Every time I try to do something useful on an RHEL clone, I find that most of the things I love about my Ubuntu servers don't exist. I can usually find a way to accomplish what I'm after, but it takes a lot more effort and frustration to get it working. In general, .deb packages work better than .rpm packages, and include many convenience features that make them easier to use. Getting back to the original post: has not been available in 32 bit flavors for a number of major releases. But Debian still supports it. A link to a network install ISO, which will require Internet access: https://cdimage.debian.org/debian-cd/current/i386/iso-cd/debian-11.5.0-i386-netinst.iso If the Internet requirement is a problem, you can find larger DVD images that can install a full system without Internet. SUCCESS! I built a VM and installed that Debian ISO on it. I did not install a GUI. Once I got it booted up, I was able to do "apt update && apt install -y openjdk-11-jdk" (as root) with no trouble. If you just need the JRE, you can install openjdk-11-jre instead. Once Java was installed, I downloaded the latest tomcat 10, extracted it, and started it. I was then able to access port 8080 in a browser and see the "successfully installed Tomcat" page. Note that 32 bit Java is limited to a 2GB heap. Limitations like this are one of the primary reasons that 32 bit support is rapidly disappearing from the software world. Chances are of course that your 32 bit system won't really have an issue with that limitation. The Linux kernel dropped support for 386 and 486 CPUs some time ago. So I hope your 32 bit system has at least a Pentium CPU. I am not positive that i586 support is still around in Debian, but i686 is there for sure.

Java 9 dropped 32-bit so it only has 64-bit by default. Maybe you have Java 8 instead of Java 9.
