Re: Servlet on Tomcat + Oracle +ISU 8859-8 (Hebrew CharSet) - encodin g problem
Hi there. May be this bug report http://issues.apache.org/bugzilla/show_bug.cgi?id=23929 will enlighten you, me and others who have issues with i18n. Very professional explanation of the problem, thanks to Remy.

Re: Servlet on Tomcat + Oracle +ISU 8859-8 (Hebrew CharSet) - encodin g problem
This is my problem also, and sadly it's so since long time I use Tomcat. I've attach a simple little test case .war file to reproduce the problem. There are four HTML forms there, two of them submits to JSP page (GET and POST methods), others go to servlet (same methods). On top of it is a select field allowing to define an encoding for future submits. It acts as following: after choosing it and submitting that select the JSP page is reloaded with that encoding, setting its response.setContentType() and setting session attribute named tHAVW07QUf (for uniqueness, see below). Now, one can submit any form presented below. I've deployed a filter.SetCharacterEncodingFilter (taken from standard Tomcat distribution), with one modification: during every request it reads session attribute tHAVW07QUf and sets requests' encoding accordingly. If that attribute is absent, it reads its init parameter given in web.xml as usually. So, instead of hard-coding character incoding in web.xml, I can set it online. According to filters.RequestDumperFilter (also Tomcat's standard filter) it works. So, let's see what we have here. The result on my machine is that any GET methods produces broken output of the parameter passed as URL-encoded %XX%XX%XX string, actual encoding of which is set by select box on the first page. Any combinations of encoding, submit methods and target actions (JSP or Servlet) give me broken output, except two of them -- utf-8 POST to JSP and utf-8 POST to Servlet. I looked at Tomcat's some source files, namely org.apache.catalina.util.RequestUtil.URLDecode(byte[], String) and org.apache.catalina.util.RequestUtil.parseParameters(java.util.Map, byte[], String), and see how url-encoded request parameters are parsed, but I don't know if it's the right place to see. Ah, and one note. I tried to run Tomcat with -Dfile.encoding=koi8-r option to set default byte[]-String conversion mapping to koi8-r (for example), and even this does not help me much, though it sets the new default. This behaviour was there on 4.x and 5.x versions, seems like nothing is changing. I don't state that I've done all tests correctly, so in any error please fix my mind. The only question is: how one can universally and correctly handle non-ASCII request parameters and get rightly decoded output?

Some fixes to WAR file posted recently. Now POST methods all work fine, but none of GET.
