Seam组件创建失败，请帮忙看看错哪了

Seam组件创建失败，请帮忙看看哪里错了！
Seam组件代码如下：

Java code

import java.util.LinkedHashMap;import java.util.Map;import javax.ejb.Stateless;import org.jboss.seam.ScopeType;import org.jboss.seam.annotations.Create;import org.jboss.seam.annotations.Name;import org.jboss.seam.annotations.Scope;@Stateless@Name("roleSet")@Scope(ScopeType.APPLICATION)public class RoleSetBean implements RoleSet {    private final String[] roles = { "系统管理员", "财务", "出纳", "总经理", "项目经理" };    private Map<String, String> roleItems = new LinkedHashMap<String, String>();    @Create    public void loadRoleItems() {        roleItems.clear();        for (int i = 0; i < roles.length; i++) {            roleItems.put(roles[i], roles[i]);        }    }    public Map<String, String> getRoleItems() {        return roleItems;    }}

发布时报错，错误信息如下：

[解决办法]
你把@Scope(ScopeType.APPLICATION)去掉试试看。
我记得stateless session bean总是存在于无状态上下文中，不能放在应用程序上下文中。
