从jboss seam调用私有方法

我想从Servlet类调用Seam组件私有方法。我使用servlet类作为ContextualHttpServletRequest，因此我可以访问组件bean。检查代码示例。

protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException,
        IOException {
    String userId = "U00001";
    String userGroupCd = "00000000";
    FacesContext facesContext = null;
    try {
        facesContext = getFacesContext(request, response);
    } catch (Exception e) {
        e.printStackTrace();
    }
    loginUtility = (ClientUtility) Component.getInstance("utility");
    Method clientInfoMethod = null;
    try {
        clientInfoMethod = getDeclaredMethod(loginUtility, "createClientInfo", String.class, String.class);
        clientInfoMethod.setAccessible(true);
        clientInfoMethod.invoke(loginUtility, userId, userGroupCd);

    } catch (IllegalArgumentException e1) {
        // TODO 自動生成された catch ブロック
        e1.printStackTrace();
    } catch (SecurityException e1) {
        // TODO 自動生成された catch ブロック
        e1.printStackTrace();
    } catch (IllegalAccessException e1) {
        // TODO 自動生成された catch ブロック
        e1.printStackTrace();
    } catch (InvocationTargetException e1) {
        // TODO 自動生成された catch ブロック
        e1.printStackTrace();
        // } catch (NoSuchMethodException e1) {
        // // TODO 自動生成された catch ブロック
        // e1.printStackTrace();
    } finally {
        clientInfoMethod.setAccessible(false);
    }
}

private <T extends Object> Method getDeclaredMethod(T obj, String name, Class<?>... parameters) {
    Method declaredMethod = null;
    Method[] methods = Component.forName("loginUtility").getBeanClass().getDeclaredMethods();
    for (Method var : methods) {
        if (var.getName().contains(name) && parameters.length == var.getParameterTypes().length) {
            declaredMethod = var;
            return declaredMethod;
        }
    }
    return declaredMethod;
}

接缝组件结构如下：

@Name("utility")
@Scope(ScopeType.SESSION)
public class ClientUtility implements IfFlowUtility, Serializable {
  private void createClientInfo(String userId, String userGroupCd) {

    InternalClientInfo info = (InternalClientInfo) Contexts.getSessionContext().get(SESSION_KEY_CLIENT_INFO);
    if (info == null) {
        info = new InternalClientInfo();
    }

    info.setUserId(userId);
    info.setUserGroupCd(userGroupCd);

    HttpServletRequestUtil util = new HttpServletRequestUtil();
    info.setClientINetAddr(util.getClientINetAddr());
    HttpSession session = util.getSession();

    Conversation conv = (Conversation) Contexts.getConversationContext().get(CONTEXT_NAME_CONVERSATION);

    if (conv != null) {
        info.setConvasationId(conv.getId());
        info.setViewName(conv.getViewId());

    }

    info.setSessionId(session.getId());
    info.setAuthToken(loginStatusManager.getAuthToken(userId, userGroupCd));
    this.setSessionId(info.getSessionId());
    this.clientInfo = info;
    this.accessor.setSessionAttribute(SESSION_KEY_CLIENT_INFO, clientInfo);
  }
}

但是当调用clientInfoMethod.invoke（）方法时出现以下错误：
