jsf+flex integration problem

**mervinjmicky** · 07-03-2011, 01:16 PM

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:
Hello,
I'm traying integrate JSF and FLEX. I created simple www app with flex(from blazeDS) library and jsf framework in netbeans ide.
My web.xml

Java Code:

<?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>

Then i wrote simple controler class:

Java Code:

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);
    }
}

For this class i made bean in faces=config.xml:

Java Code:

<?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>

And jsf work correct. I can see on my test page user1,user2,user3. Problem is when i am trying acces to this bean via remote objects in flex.
I have done everithing like in this post:
accessing jsf bean from blazeds client - Stack Overflow. My factory class:

Java Code:

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;
        }
    }
}}

My remoting-config.xml

Java Code:

<?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>

  </service>

And services-config.xml

Java Code:
