Jar file dependency in a JSP page

Thread view:

unlikeablePorpoise@gmail.com - 23 Mar 2007 22:57 GMT

I have written a java class (let's just call it foo) that can
successfully be accessed from my jsp page by jsp:useBean. Then I
imported some methods from a jar that are now being used in foo, and
this compiles successfully.

The problem is that now my jsp page won't compile anymore (after
importing the methods from the jar). I get a Jasper exception on the
line where I make a call to the method imported from the jar. Do I
have to import the jar on the jsp page as well?

Let me know if I need to clarify my question

Thanks,
Sarah

Let's rather call it Foo.

See Lew's comment re capitalisation , but
further than that, why not call it what
it is? Is the name a secret?

It might be that the server has yet to notice
the altered Jar. Try refreshing the server.

To achieve that refresh, I would usually stop
and restart the server, but Lew pointed out
recently that it can be done while the server
is running (which is preferable - especially
if it is a production server!).

Have you put the jar file in WEB-INF/lib so it is available at runtime
and restarted the web app ?
