Encoding / GET vs. POST

[junkie]

I can successfully POST any Unicode character (especially non ISO-8859-1 chars) with my JSF-forms without having to deal with encodings.

But I have one Seam component that takes parameters via @RequestParameter and GET.

In this case I have to manually convert the input String like this:

in = new String(in.getBytes("8859_1"), "UTF-8");

If the input parameter was POSTed I don't need to do that.

Why does Tomcat/JBoss/Seam convert the Unicode to ISO-8859-1 if the input was sent via GET?

Because URLs are not Unicode? (Yes, I know that there are extensions...)

Thanks Christian - I believe that URLs are not ISO-8859-1 either... I have finally found this here in the forum:

"If you are using Tomcat or JBoss all you have to do is [...] set URIEncoding to whatever character encoding you are using for the tomcat Connector in the server.xml.

The default encoding is ISO-8859-1 for Tomcat if not set explicitly.

<Connector port="8080" ... URIEncoding="UTF-8" .../>"

I did that and now I can use my UTF-8 encoded URL parameters directly without conversion from ISO-8859-1 to Unicode.

Can someone please recommend a book that deals with these kind of configurations?
