Witam,
próbuje zintegrować JSF z Flexem. Niestety z marnym skutkiem. Albo czegoś nie rozumiem albo źle się za to zabieram.
Stworzyłem sobie prostą aplikacje www, dodałem biblioteki flexa oraz frameworka JSF. Web xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Development</param-value>
</context-param>
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>
</servlet-mapping>
<listener>
<listener-class>flex.messaging.HttpFlexSession</listener-class>
</listener>
<!-- MessageBroker Servlet -->
<servlet>
<servlet-name>MessageBrokerServlet</servlet-name>
<servlet-class>flex.messaging.MessageBrokerServlet</servlet-class>
<init-param>
<param-name>services.configuration.file</param-name>
<param-value>/WEB-INF/flex/services-config.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>MessageBrokerServlet</servlet-name>
<url-pattern>/messagebroker/*</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>
30
</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>faces/index.xhtml</welcome-file>
</welcome-file-list>
</web-app>
Następnie utworzyłem prosty kontroler:
public class UsersControler implements Serializable{
public UsersControler(){
users.add("user1");
users.add("user2");
users.add("user2");
}
private List<String> users = new ArrayList<String>();
public List getUsers() {
return users;
}
public String getName(){
return users.get(0);
}
}
Dla którego stworzyłem beana w faces-config.xml:
<?xml version='1.0' encoding='UTF-8'?>
<faces-config version="2.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd">
<managed-bean>
<managed-bean-name>usersService</managed-bean-name>
<managed-bean-class>controlers.UsersControler</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
</faces-config>
Dla takiej konfiguracji strona w JSF wyświetla mi się bez problemu(widzę user1, user2, user3). Jeśli chodzi o flexa to zrobiłem wg tego: http://stackoverflow.com/questions/2361546/accessing-jsf-bean-from-blazeds-client małą "fabryczkę":
public class BeanFactory implements FlexFactory {
private static final String SOURCE = "source";
public void initialize(String id, ConfigMap configMap) {}
public FactoryInstance createFactoryInstance(String id, ConfigMap properties) {
BeanFactoryInstance instance = new BeanFactoryInstance(this, id, properties);
instance.setSource(properties.getPropertyAsString(SOURCE, instance.getId()));
System.out.println(instance.toString());
return instance;
}
public Object lookup(FactoryInstance inst) {
BeanFactoryInstance factoryInstance = (BeanFactoryInstance) inst;
return factoryInstance.lookup();
}
static class BeanFactoryInstance extends FactoryInstance {
BeanFactoryInstance(BeanFactory factory, String id, ConfigMap properties) {
super(factory, id, properties);
}
@Override
public String toString() {
return "BeanFactory instance for id=" + getId() + " source=" + getSource() + " scope=" + getScope();
}
@Override
public Object lookup() {
HttpServletRequest hsr = FlexContext.getHttpRequest();
String beanName = getSource();
try
{
Object o = hsr.getSession().getAttribute(beanName);
return o;
}
catch (Exception e)
{
ServiceException se = new ServiceException();
String msg = "Java Bean '" + beanName + "' does not exist.";
se.setMessage(msg);
se.setRootCause(e);
se.setDetails(msg);
se.setCode("Server.Processing");
throw se;
}
}
}}
Następnie skonfigurowałem remoting-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<service id="remoting-service"
class="flex.messaging.services.RemotingService">
<adapters>
<adapter-definition id="java-object" class="flex.messaging.services.remoting.adapters.JavaAdapter" default="true"/>
</adapters>
<default-channels>
<channel ref="my-amf"/>
</default-channels>
<!-- <destination id="usersService">

</destination> -->
<destination id="usersService">
<properties>
<factory>beanFactory</factory>
<source>usersService</source>
<scope>session</scope>
</properties>
</destination>
</service>
Oraz services-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<services-config>
<services>
<service-include file-path="remoting-config.xml" />

Pliki proxy-config.xml oraz messaging-config.xml zostawilem bez zmian tak jak były w samplach blazeDS. Podczas uruchomienia tomcata dosstaje informację:

Chodzi mi o ostatnią linijkę tak jak by instancja fabryki się tworzyła ale zasięg request ? Tego nie rozumiem skoro wszędzie mam session. Chyba, że to dotyczy właśnie tej fabryki nie wiem ...
Podczas uruchomienia samej aplikacji w przeglądarce dostaję komunikat:
[MessagingError message='Destination 'usersService' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']
Couldn't establish a connection to 'usersService'
Jeśli chodzi a aplikację flexa:
<?xml version="1.0" encoding="utf-8"?>

I niestety to nie działa. Prosił bym o jakąś podpowiedź albo nakierowanie na właściwy trop. Z góry dziękuje.
