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.
