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?

Environment variables can be defined temporarily by booting to MS-DOS mode, defining variables with the SET command and then starting Windows. Variables defined in this way persist until the system is rebooted.
To set (or change) a environment variable, use command " set varname=value ". There shall be no spaces before and after the '=' sign. To unset an environment variable, use " set varname= ", i.e., set it to an empty string.
Use double percent signs ( %% ) to carry out the for command within a batch file. Variables are case sensitive, and they must be represented with an alphabetical value such as %a, %b, or %c. ( <set> ) Required. Specifies one or more files, directories, or text strings, or a range of values on which to run the command.
In your file, at the top, use setlocal, when exiting the file, use endlocal.
