Temporarily set Environment variables with batch file

Question

I'd like temporarily set Environment variables like Catalina and Java_Home using a batch file, without making persistent changes.

Changes should be removed after the execution of a web-page.

There's a way to do it?

All variables you create in a batch file are volatile when using the SET command. They will all disappear after the batch file closes. – Sisak

Well, after the command prompt that had the script running in it closes (just in case you ran the script from the command line instead of double-clicking it). – Bothwell

setlocal is generally good practice as well. Changes to variables made within a setlocal session are forgotten when the script ends or endlocal is encountered. As a bonus, setlocal also preserves the current working directory. – Basutoland

Yes. Setlocal/endlocal is a best practice in my book – Sisak

Answer 1

In your file, at the top, use setlocal, when exiting the file, use endlocal.
