Hello, I've just done the test. I found out that (using your example) X and Y match, but they don't match with Z. I got the parameter as a request attribute from the jsp and compared it to a string I setted... for the second test, I encoded it as a byte using UTF-8 and didn't work?
I must say I'm quite a newbie, so I don't know much about this encoding thing. How do I do to set a unique type of encoding to my whole app? Is it using the filters Joe mencioned? I'm reading about them to find out how I implement them. If I do this, things will be ok? Or is there anything else I should do?
