I have (for the purpose of testing) two strings, one is the string with the utf-8 characters, the other is an encoded form of the url (which is encoded into a series of "%" followed by two English letters). Do you recommend having something else here? Some more info: I placed a filter on pattern "/*". When my request with the UTF-8 url comes in, I call httpRequest.getServletPath() and httpRequest.getRequestURI(). As expected, I get the UTF-8 version of the servlet path (ie: decoded) and the ASCII request URI (ie: encoded) respectively. This means that the request is reaching my server. It's the next step, the step where the servlet path is mapped to my specified url pattern, that I want to explore. But I don't know how to explore this. Where can I control how the url pattern is matched with the incoming url? Although I can only conceive two options for how the incoming url is matched with the url pattern and I've tried both (either the UTF-8 version of the request url is matched against the pattern or the encoded version is matched against the pattern). > > >> Therefore, the xml loading process/compiler/tomcat/netbeans > >> shouldn't do anything to change it (in the case where I encode > >> the pattern), but the servlet still isn't found. > > Well, if you use annotations, the XML shouldn't be a problem at all, > of course.

I have tried placing the regular hebrew into the attribute as well as placing the encoded form of the hebrew (ie: /package/[some hebrew] & /package/%D7%99%D7... respectively). The latter is how wikipedia does it, inspect the elements to see for yourself ( https://he.wikipedia.org/wiki/%D7%9E%D7%9C%D7%97%D7%9E%D7%AA_%D7%94%D7%A2%D7%A6%D7%9E%D7%90%D7%95%D7%AA) (...the browser automatically encodes the link when I copy it :) > > You might want to make sure that Tomcat is delivering all responses in > UTF-8, so that the browser (hopefully) decides to send the URL for the > *next* page in UTF-8 instead of some weird ISO-8859-1 mess. > > I place a filter that sets the response encoding to UTF-8, doesn't help.
