S2: Using Outbound Rules with UrlRewriter
Has anyone used the UrlRewriter outbound rules with Struts 2?
UrlRewriter requires that the urls go through response.encodeURL().
In JSP and JSTL examples:
<a href="<%= response.encodeURL("/world.jsp?country=usa&city=nyc")
%>">nyc</a>
<a href="<c:url value="/world.jsp?country=${country}&city=${city}"
/>">nyc</a>
What is the Struts2 equivalent way? (s:url encode="true" does not work).
Thanks,
Daniel

Hi Wes,
Thanks for taking time to answer my question. Guess I was not clear with
the the examples I gave. Yes, I am using all Struts actions, s:url, s:a
tags, and everything. The thing is the Struts tags:
<s:url var="theLink" action="world" namespace="/whatever" *encode="true"*>
<s:param name=country value="whatever"/>
<s:param name="city" value="whatever"/>
</s:url>
<s:a href="#theLink">nyc</s:a>
don't seem to implicitly call "response.encodeURL" as the c:url tag would if
I used plain JSP and JSTL. As a result, UrlRewritter cannot intercept it
and apply the outbound rules. I was wondering if there were ways to get
around that.
Cheers,
Daniel

I'm not sure if I'm answering your question, but the struts2 way would differ
slightly from your example in two ways -
1. world.jsp should be converted to an action rather than a JSP. You could
simple map world.jsp to ActionSupport if you didn't want to code a whole
action, but since your taking parameters, I would suggest writing an action
for it.
2. Rather than using a scriptlet, you'd use the struts2 tags to generate the
link. This could be done in a few ways -
2a. generate the url with the s:url tag and assign it to a variable on the
value stack to use with the s:a tag -
<s:url var="theLink" action="world" namespace="/whatever"><s:param
name=country value="whatever"/><s:param name="city" value="whatever"/></s:url>
<s:a href="#theLink">nyc</s:a>
2b. use the s:url tag right in the href= of your HTML a tag -
<a href="<s:url action="world" namespace="/whatever"><s:param ...
2c. If possible, use the recently committed (today) version of s:a -
<s:a action="world" namespace="/whatever"><s:param ...
Again, I'm not sure if I'm answering your question, but I know one of the
reasons I use Struts is to avoid adding scriptlets.
