Any number of characters: .*
Code:
sed "s/$.*\././"

Only the literal . needs a \ escape.
The literal $ can have one for clarity, but then I'd put the sed script in 'ticks'.
Code:
sed 's/\$.*\././'

I tried below worked for me.
Code:
sed 's/$.*/.jsp/g'


Not sure if it has any edge cases. Thanks for reply.

This works only once per line, so the g can be left out.
Code:
sed 's/$.*/.jsp/'

to make it work one or more time per line, you could try:
Code:
sed 's/$[^.]*//g'

No edge cases. You put back what you matched too much.

The /g option for multi-substituion on the same line is not needed:
Code:
echo 'aaaa$bbbb.cccc$dddd.eeee' | sed 's/\$.*\././'
echo 'aaaa$bbbb.cccc$dddd.eeee' | sed 's/\$.*\././g'

give the same result, because of the greedy .* match
You only see a multi-substitution effect with a minimum match
Code:
echo 'aaaa$bbbb.cccc$dddd.eeee' | sed 's/\$[^.]*\././'
echo 'aaaa$bbbb.cccc$dddd.eeee' | sed 's/\$[^.]*\././g'
