Re: JSP advice

[Enrique Perez <pe...@dit.upm.es>]

Hi Aaron,

You were right, I've made a mistake writing the path to the JSPs folder :$
I've written one letter in lower-case when it should be a capital letter...

Yet, I had to change another thing. It's related to the core tag 
library... because it complaints about been unable to find the URI =/
When I commented the line where this taglib is invoked, the content 
rendered normally...

Thanks a lot,
Enrique
