Hej gruppe
Jeg er begyndt at læse på struts (i bogen Jakarta Struts Live) som jeg
hentede gratis fra theserverside.com:
http://www.theserverside.com/books/sourcebeat/JakartaStrutsLive/index.tss
Der er et simpelt eksempel som jeg ville prøve at bygge med Ant som
foreskrevet (det første eksempel).
Servlet'en ser således ud:
------------
package strutsTutorial;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
public class UserRegistrationAction extends Action {
public ActionForward execute (ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
return mapping.findForward("success");
}
}
-----------------
men ved kompilering får jeg fejl på HttpServletRe*-klasserne om at de
ikke findes..
Jeg har j2sdk og tomcat5 installeret på min gentoo-boks. Jeg har gjort
som foreskrevet i vejledningen..

This is a blank Struts configuration file with an example

Tiles and the Struts Validator are configured using the factory
defaults

NOTE: If you have a generator tool to create the corresponding Java
classes
for you, you could include the details in the "form-bean"
declarations.
Otherwise, you would only define the "form-bean" element itself,
with the
corresponding "name" and "type" attributes, as shown here.

This plugin initialize Tiles definition factory. This later can
takes some
parameters explained here after. The plugin first read parameters from
web.xml, thenoverload them with parameters defined here. All parameters
are optional.
The plugin should be declared in each struts-config file.
- definitions-config: (optional)
Specify configuration file names. There can be several comma
separated file names (default: ?? )
- moduleAware: (optional - struts1.1)
Specify if the Tiles definition factory is module aware. If
true
(default), there will be one factory for each Struts module.
If false, there will be one common factory for all module. In this
later case, it is still needed to declare one plugin per
module.
The factory will be initialized with parameters found in the
first
initialized plugin (generally the one associated with the
default
module).
true : One factory per module. (default)
false : one single shared factory for all modules
- definitions-parser-validate: (optional)
Specify if xml parser should validate the Tiles configuration
file.
true : validate. DTD should be specified in file header (default)
false : no validation
Paths found in Tiles definitions are relative to the main context.
