Looks ok syntaxwise. Have you checked that the class is being reloaded
properly by the jsp engine you're using? check for caches, or the .class
file in two places on the classpath, etc. There can be some nice gotchas
with some of the servlet engines to do with class reloading (or not as
the case may be). To be sure you've really got to shut down and restart
the servlet engine (which can be a real pain in a production
environment....).
And not wanting to be critical, but speaking from personal (bitter)
experience, it is a _really_ bad idea to use floats for prices. Check
out using BigDecimal instead - that is if you ever want to consider
trading in Turkey, or Italy, etc...! Using BigDecimal also maps nicely
to using get/setBigDecimal under JDBC, and to Oracle's number(38,2) type
for currency use (among other things).
