Besides that, the meta tag doesn't quite work.

Tomcat outputs:

Content-Type: text/html; charset=iso-8859-1

As one of its standard headers.  So, if you're like us, and you're trying to 
output Simplified Chinese, the Simplified Chinese will still show up as 
garbage characters.  The meta tag only overrode the http response header 
under Mozilla, and only under certain conditions.

To get around this problem, you can change your page directive to be:

<%@page contentType="text/html"%>

Note, how I didn't include the charset as part of the content type.

The default is:

<%@page contentType="text/html; charset=iso-8559-1"%>

So, what you can do is:

<%@page contentType="text/html"%>





This is my ÖÐÎÄ text.


And if you've got lazy programmers, you can always write a perl script to go 
through every page that's already been written and just insert it.  Every 
subsequent page however, will need to be updated manually.  Or, like I 
did...a combination of perl and shell scripts :)  I had the task of updating 
400 JSP files, and there was no damned way I was going to do it manually. :p

If you'd like, you can email me privately, and I'll send you the perl utility 
I used as a base for my scripts, but the shell scripts are heavily site 
dependent.

JSP 2.0 adds directives that let you do this, so you'll see it in Tomcat 5
eventually.  There is no such facility in any earlier version, though.

You're correct -- pageEncoding tells the JSP compiler what encoding the
source page is in at *compile* time.  Filters won't be able to affect
that.

Sounds like time to get some new developers :-).

Or provide a template page (that includes this directive) as a starting
point for creating new pages, and make them use it.

Thank you!

I think that javac -encoding is what I need.
You write that you don't know way to set it in web.xml...
But may be this is possible?

Sorry, my answer was a bit to fast.

There is more than one aspect of the encoding:

- Compiletime
  This aspect defines which character set is/was used to write the
source
  of the page. That's what you can define with the -encoding option of
javac.

  I'm not shure, how to specify that for tomcat without the
pagedirective.
  (As far as I can see, it's not possible to configure the encoding in
web.xml)

- Runtime
  This aspect defines the default character encoding while reading from
streams and 
  writing to streams. This can be controlled by the system property
file.encoding.
  I would expect that if you set this attribute, your value is used by
tomcat to
  generate and compile the page. (The spec is quite open at that point:
'A JSP 
  container may use some implementation-dependent heuristics and/or
  structure to determine what the expected character encoding of a JSP
is...')
  I haven't tried this.

- Requesttime
  This aspect defines which character set shall be used to read the
request
  from the client and to write the response to the client. This can be
controlled
  by a filter.

Could you tell me how?
As I understand, pageEncoding directive works at compile time
and it is impossible to do this with filter?

[Ralph Einfeldt]

AFAIK it not possible to set the default encoding by configuration.
But you could write a servlet filter that does this.

I understand.
But our devepopers are too lazy ;-)
They don't want to write this line in every jsp...
Is it possible to configure Tomcat (something else) to set default encoding?

Hi,

yes, just like HTML add a line like this:

 

 
character set
