Still trying to figure this one out. Below is my original action where I
would compare the values of 'view' and return a view mapping pending the
value of view ...
public class Products extends ActionSupport implements ParameterAware {
private Map params;
...
public void setParameters(Map map) { this.params = map; }
public String doExecute() throws Exception {
if (view.equals("myview.a")) {
return "selectA.success";
}
else if (view.equals("myview.b")) {
return "selectB.success";
}
return "select.error";
}
Then I needed to capture the parameter from within the action (coming from
the velocity *.vm template) so I changed the class I extended from and now
have ...
public class Products extends WebWorkVelocityServlet implements
ParameterAware {
private Map params;
...
public void setParameters(Map map) { this.params = map; }
public Template handleRequest(Context context) {
HttpServletRequest request = (HttpServletRequest)
context.get(REQUEST);
HttpServletResponse response = (HttpServletResponse)
context.get(RESPONSE);
}
}
As I understand it, I now have the handleRequest() method above so that I
can get a query string parameter from the servlet now and write something
like this in the template page ...
--- *.vm file
#if ( $reqParser.getParameter("myParam").equals("this_string") )
## do something
#end
The problem is that whereas I had the execute() method from the first ex.
(extended from ActionSupport) to compare views and return a different view
pending on the value of view, I don't know how to do this (return views
pending a query string parameter in the servlet request) w/ the
WebWorkVelocityServlet.
So what I have is a query string coming from the template to the action, and
then I'll return a view mapping w/ query string parameters back to the
browser.
Any help much appreciated.
