红帽全球峰会6.2.2. 使用 EJB 方法权限
<method-permission> 元素定义允许访问 <method> 元素定义的 EJB 方法的逻辑角色。几个示例演示了 xml 的语法。可能存在多个方法权限语句，它们具有累积效果。<method-permission> 元素是 < 元素的子项。
ejb-jar> 描述符 <assembly-descriptor >
XML 语法是将注释用作 EJB 方法权限的替代选择。
示例：允许角色访问企业 JavaBeans 的所有方法
<method-permission>
<description>The employee and temp-employee roles may access any method
of the EmployeeService bean </description>
<role-name>employee</role-name>
<role-name>temp-employee</role-name>

<method-name>*</method-name>
</method>
</method-permission>
<method-permission>

<role-name>temp-employee</role-name>
<method>
<ejb-name>EmployeeService</ejb-name>
<method-name>*</method-name>
</method>
</method-permission>示例：允许角色访问企业 JavaBeans 和限制方法参数的 Certain 方法

</method-permission>示例：允许任何经过身份验证的用户访问 Enterprise JavaBeans 的方法
使用 <unchecked/> 元素时，任何经过身份验证的用户都可以使用指定的方法。
<method-permission>
<description>Any authenticated user may access any method of the
EmployeeServiceHelp bean</description>
