Hi,
I am building a web application with Struts2 and Tomcat 5.5 as the web
container. One action parameter is passed as part of the URL and may
contain Unicode characters:
<action name="article/*" class="...">
<param name="title">{1}</param>
<result>/ShowArticle.jsp</result>
</action>
The <s:url> tag encodes this parameter as UTF-8, and I declared in my
tomcat server.xml the matching encoding
<Connector URIEncoding="UTF-8" ... port="8081" />
So far, so good. Everything works fine. Trouble starts when I use
redirect results or redirect-action result with Unicode characters in
the title part of the url:
<action name="editarticle/*" class="...">
<param name="title">{1}</param>
<result name="save" type="redirect">article/${title}</result>
...
</action>
Than the redirect URL is encoded in ISO-8859-1, which is than
misinterpreted as UTF-8 when send back to tomcat. While debugging I
think this encoding is done in HTTPServletResponse#sendRedirect by default.
I can workaround that by introducing a new attribute to my action class:
public String getTitleURLEncoded() throws Exception {
return URLEncoder.encode(getTitle(), "UTF-8");
}
and change the result to
<result name="save" type="redirect">article/${titleURLEncoded}</result>
This works, but it 'feels' wrong. Is there some other solution to this?
Any input is welcome.
Best regards, Alex
