How to test an updated .jar?

[A deaf heart, a loose liver]

I make frequent changes to a .jar file for testing. If I kill the
browser and open a new one, it loads the new version of the .jar
into Java.

Can I reset the engine and load the new .jar without killing the
browser? (I test with a variety of browsers.)

-:-
"Hey, Rocky! Watch me pull a UNIX program out of my
source directory!"
"AGAIN?"
"Nothin' up my sleeve ... PRESTO!"

SOURCE-COMPUTER. IBM-7044.
OBJECT-COMPUTER. IBM-7044.

"No doubt about it--I gotta get a new source directory!"

Yes. Bring up the Java Console of your
variety of browsers and type the option
that is followed by the words..
'clear classloader cache'.
