RoleManager

[Mohamed]

Hi All, 

I tried to use the RoleManager to get the Class Name for another Implementaion of a 
component using the <hint> tag, But it failed ... I don't know if I use it in a proper 
way ... I have a working Interface (ITestManger) and tow implementaion classes : 
(TestManger),(SecondTestManger)

and the Roles.xml file is like :
**************************************************************************
<role-list>
<role
        name="com.imkenberg.bo.Order.test.ITestManger"
        shorthand="test"

        default-class="com.imkenberg.bo.Order.test.SecondTestManger">
        <hint shorthand="manager1"
            class="com.imkenberg.bo.Order.test.TestManger"/>
        <hint shorthand="manager2"
            class="com.imkenberg.bo.Order.test.SecondTestManger"/>
    </role>
    
<!--default-class="org.apache.avalon.excalibur.component.ExcaliburComponentSelector">-->
</role-list>
***************************************************************************
below is a snippet code of what I'm doing:
****************************************************************************
    static String rootdir = "c:/avalon";
    static ComponentManager manager;
    static ExcaliburComponentManager exManager;
    static DefaultRoleManager roleManager;
    ExcaliburComponentSelector exSelector;

static {
        try {
            init();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }    
private static void init() throws Exception {

    roleManager = new DefaultRoleManager();
        DefaultContext context = new DefaultContext();
        context.put("context-root", new File(rootdir));
        ExcaliburComponentManagerCreator ecmc = new 
ExcaliburComponentManagerCreator(context, new File(rootdir + "/logkit.xml"),
                new File(rootdir + "/roles.xml"), new File(rootdir + "/xconf.xml"), 
null);

        manager = ecmc.getComponentManager();
        exManager = new ExcaliburComponentManager(manager);
        exManager.setRoleManager(roleManager);
}

public void execute() throws com.imkenberg.command.CommandException {
        try {
            // exSelector = (ExcaliburComponentSelector) lookup(ITestManger.ROLE, 
"manager1");
            ITestManger test = (ITestManger) lookup (  ITestManger.ROLE, "manager1");

        } catch (Exception e) {
            System.out.println("Error in Getting the Component");
        }
    }

public static Component lookup(String role, String hint) throws ComponentException {
         String className = roleManager.getDefaultClassNameForHint(role, hint);
          return exManager.lookup(className);
}
***************************************************************************************************

Does I'm doing something wrong ? is that way the proper way to use " RoleManger " to 
get  "Multiple Implemention for a component "
BTW : I used also ExcaliubarComponentselector with the RoleManger But it  also Failed.

Any Help 

Thanx in advance
