and add this to your web.xml
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<servlet-name>action</servlet-name>
</filter-mapping>
the action is the name of struts controller.

Still shouldn't be necessary.

Open up struts.jar in winzip or something and view META-INF/MANIFEST.mf
- check implementation-version.
So what does the debugging say at the end of your JSPs? Is your response
UTF-8 or iso-xxxx encoded? I bet it says the page content-type is still
iso-8859.
How are you setting your struts controller parameter (in struts-config.xml):
<set-property property="contentType"
value="text/html; charset=UTF-8"/>
Do you have any locale-encoding-mapping-list in your web.xml? You don't
need it with UTF-8. You also don't need to specify it in any
jsp-property-group since the struts controller will handle it.

I wish! If you get this solved, we can condense this thread and post it
in the struts wikki.
