.jsp page not seeing newly added function to compiled java .class file

Question

I'm working in another company's code base for a .jsp based site. Most of the site is straight up .jsp pages, but they have a few .java objects those pages use as well. I've modified one of those objects to add an extra function to it, recompiled, and yet the .jsp pages generate a "Method ... not found in class" error when I try calling it.

Obvious things I've already checked out:

• It's not a simple typo in the method name.
• The method is public.
• I'm passing the one String the method signature demands.
• The .java file has been recompiled into a .class file that has overstalled the old one.
• The object with the new function was already imported and in use.
• I have successfully modified other .java objects on this webserver (though not in this exact folder) and seen the changes take effect.

What else might it be?

Answer 1

Generally you have to explicitly set up hot-code replace in Tomcat, and usually it doesn't support adding method signatures - you may have to get the application redeployed and restarted to see the effects properly.
