problem with java & tomcat

[kali89]

my terminal tells me Java and tomcat are already installed in my MacBook Pro (a fairly new one, now running Ventura 13.2.1) but when I search for "java" or "tomcat" in the computer I can't find them...

and indeed I did install them.. and when I type in the commands to install them again, it says they're already installed, but I just can't find them when I search..

also when I run command "java" I get error too.. it says:
The operation couldn’t be completed. Unable to locate a Java Runtime that supports javac.

and if I try to install Java again it says:
Warning: openjdk 19.0.2 is already installed and up-to-date

so it installed java but not the java compiler?

also, when I google it, it says java is installed in /Library/Java/JavaVirtualMachines/
it's just not there.. I also searched for JavaVirtualMachines, it's not there..


I also installed Homebrew, and I also can't find it anywhere when I search for it..

this is ridiculous.. I don't like not knowing where things are installed in my computer...

so why can't I find where these things are installed?

would appreciate suggestions.. thank you..

Not sure how you installed all of these, but Homebrew, for example, installs the brew as a link in the /usr/local/bin directory pointing to its real location. Since /usr/local/bin is in your default path, brew works.

All packages from Homebrew end up in the /usr/local/Cellar folder, as would Tomcat.

If you install OpenJDK through HB, it won't go to the /Library/Java folder. If you install OpenJDK through an independent installer, it might end up there.

Either way, in the terminal "echo $PATH" to show you what folders you are looking in and that'll tell you where you are looking for things and if your things are in a different folder, you'll have to adjust the path to compensate.

hi, thank you for your help.. now when I do "echo $PATH" I get this..

/usr/local/bin:/System/Cryptexes/App/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/homebrew/bin:/opt/homebrew/bin
???
(I did set the path for it the other day.. (but wasn't if I had set it, so set it again and this is what I get now when I do echo $PATH...))

Cryptexes? I can't find a dir by that name in my computer..

I also can't find a dir "Cellar" in my computer..

and, as I said, I can't find any dir or file named "tomcat"..

so where is the stuff I have installed with Homebew (so far, Java and Tomcat)? I simply can't find them anywhere in my computer... the Tomcat installation comes comes with a bunch of dirs, among them a dir webapps, which is where you put the websites in Tomcat.. can't find any of it...

thanks again..
