Thank you for your help, but I already know how to implement dynamic results
and how to use parameters in my results as well. And this is also not the
point. I wanna make a "forward" rather than a "redirect" to the same page.
But it doesn't work. I have a search-form on different pages. If validation
fails on a form property, the request should be forwarded to the same page
with the field error messages displayed. So redirect to the same page is not
the choise. You also have to know, that I use Tiles for my webapp.
In my struts.xml I've defined the following:
<action name="welcome" class="com.foo.BaseAction">
<result type="tiles">welcomePage</result>
</action>
<action name="search" class="com.foo.SearchAction">
<result type="redirect-action">searchResult</result>
<result name="input" type="dispatcher">${referer}</result>
</action>
<action name="searchResult" class="com.foo.SearchResultAction">
<result type="tiles">searchResultPage</result>
</action>
The SearchAction looks like class:
public class SearchAction extends ActionSupport implements Prepareable {
private String referer;
@Override
public void prepare() throws Exception {
referer = request.getHeader( "Referer" );
if (referer==null)
referer = request.getContextPath();
}
public String getReferer() {
return referer;
}
public String execute() throws Exception
{
// do some searching
return SUCCESS;
}
}
The getter-method for the referer property returns something like
"http://localhost:9001/welcome.action";, cos the search-form is included in
my welcome-page. I've got the feeling, that Tomcat's ApplicationDispatcher
makes some request string modifications in accordance to the servlet context
path.
The location after creating the dispatcher is
"//http:/localhost:9001/welcome.action". An obviously complete useless URI.
