Seit heute habe ich das Vergnügen mich mit Struts 2 auseinander zu setzen. Nach paar Stunden Theorie wollte ich nun mal ein Tutorial Projekt zum laufen bringen. Leider funktioniert es nicht und ich habe keinen Plan woran es liegt. Achja ich nutze die IDE eclipse für mein Projekt und starte auch den Tomcat darüber.

Fehlermeldung:
Code: 
HTTP Status 404 - 

--------------------------------------------------------------------------------

type Status report

message 

description The requested resource () is not available.


--------------------------------------------------------------------------------

Apache Tomcat/6.0.29

Hier mein ganzer Code:
LoginAction.java
Java: 
package net.viralpatel.struts2;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {
	private String username;
	private String password;

	public String execute() {

		if (this.username.equals("admin")
				&& this.password.equals("admin123")) {
			return "success";
		} else {
			addActionError(getText("error.login"));
			return "error";
		}
	}

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}
}

Also wie gesagt bin blutiger Anfänger aber auch im kompletten Webprog Bereich. Deswegen würde ich gerne wissen ob schonmal meine Struktur soweit in Ordnung ist genauso wie die benötigte Dateien? Laut Konsole liegt das Problem in ner Struts lib, aber Google konnte mir auch nicht helfen.



EDIT:
Kann es jmd bitte ins richtige Forum schieben? :oops:

Tipp 1: Schalte mal in der struts.xml den Dev-Mode an:

Code: 
<constant name="struts.devMode" value="true" />

Tipp 2: Welche Action (Klasse und Methode) ruft deine eine "login"-Action in der struts.xml auf?

Irgendwie tauch in dem Log aber auch immer ein sehr komischer Pfad auf:

jar:file:/D:/Studium/Projekte/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/StrutsHelloWorld/WEB-INF/lib/struts2-core-2.2.1.jar

Wieso sucht der die Jars in einem Plugin-Verzeichnis von Eclipse? Wo deployst du denn das WAR-File?

Alle nötigen struts2 libs habe ich standardmäßig per Preferences -> Java Build -> Add external JARs eingefügt. Warum er im Plugin Folder sucht kein Plan. Also ich glaube ich deploye nirgends eine WAR-File. Jedenfalls mir nicht bekannt und weiß auch nicht was du damit meinst.

Mit deployen meine ich das "bereit stellen" des Programmes auf einem Server wie Tomcat, Glassfish, Jboss, ....
In deinem Fall hast du dein Programm ja irgendwie auf einen Tomcat bereitgestellt (deployed).

Hast du denn auch schon mal die anderen Punkte geprüft? (Dev-Mode und Name der Action-Methode)?

Hat sich erledigt! Es lag an meiner Struts2 Version. Nutze nun die vorletzte Version 2.0.14 und alles läuft wie geschmiert. Trotzdem danke für die Infos.

Nur zur Erklärung für mich:
- Was bringt der DEV Mode in der xml?
@gman
- Die Frage bezüglich Tipp 2 ist mir nicht klar!

Der Dev-Mode ist nützlich für Entwickler (Developer), er führt dazu das mehr Fehlermeldungen auftreten und
Einstellungen öfter neu geladen werden als später in Produktion nötig wäre.

In der struts.xml steht das du für die login-Action die Methode "authenticate" nutzen willst, aber in der
Action steht nur die "execute"-Methode.

Ich würde für produktive Projekte auf die aktuelle Struts-Version gehen, da diese eine schwerwiegende
Sicherheitslücke schließt!
