Hallo,
ich arbeite zur Zeit für ein Uni-Projekt mit openamf, Struts, Tomcat und habe ein Problem, aus Flash heraus eine Java-Methode aufzurufen.

-------------------------------------------
Der Tomcat meldet folgenden Fehler:

[INFO] RESPONSE - RESPONSE:
[AMFBody: {serviceName=null, serviceMethodName=null, response=null, type=UNKNOWN, value=[AMFError: {ASObject[type=null]}]}]

[INFO] AMFSerializer - Serializing Message, for more info turn on debug level

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

Mein Actionscript:

#include "NetServices.as"

var gatewayPath = "http://localhost:8080/elearning/gateway";
var servicePath = "service.CreateProtocol";

NetServices.setDefaultGatewayURL(gatewayPath);

var serviceConnection = NetServices.createGatewayConnection();
var serviceObject = serviceConnection.getService(servicePath, this);

createProtocol = function(){
trace("in createProtocol");
serviceObject.createPuzzleProtocol();
}

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

Meine Java-Klasse:

package service;
public class CreateProtocol {
public void createPuzzleProtocol(){
System.out.println("---- in CreateProtocol createPuzzleProtocol ----");
}
}

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

Die web.xml habe ich um folgende Einträge ergänzt:

<servlet>
<servlet-name>DefaultGateway</servlet-name>
<display-name>DefaultGateway</display-name>
<description>DefaultGateway</description>
<servlet-class>org.openamf.DefaultGateway</servlet-class>
<init-param>
<param-name>OPENAMF_CONFIG</param-name>
<param-value>/WEB-INF/openamf-config.xml</param-value>
<description>Location of the OpenAMF config file.</description>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>DefaultGateway</servlet-name>
<url-pattern>/gateway</url-pattern>
</servlet-mapping>

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

Ich habe die openamf-config.xml in meinen WEB-INF kopiert.
Versuchsweise habe ich folgendes eingetragen:

<service>
<name>CreateProtocol</name>
<service-location>service.CreateProtocol</service-location>
<invoker-ref>Java</invoker-ref>
<method>
<!-- Operation's are matched by the name and parameters -->
<name>createPuzzleProtocol</name>
</method>
</service>

Ist das richtig und notwendig?

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

Ich habe auch alle .jar-Dateien in den Tomcat>common>lib kopiert.

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

Kann es sein, dass es Probleme macht, dass der WEB-INF-Ordner nicht direkt unter "elearning" liegt, sondern ein web-ordner dazwischen liegt?
Der Pfad zur CreateProtocol.class ist wie folgt:
http://localhost:8080/elearning/web/...CreateProtocol

Noch eine Frage: Wozu braucht man die build-webservice.xml?

Vielen Dank für Tipps!
