9.2.2.2. EJB メソッドパーミッションの使用
概要
< ;method-permission> 要素は、<method> 要素で定義された EJB メソッドへのアクセスが許可される論理ロールを定義 します。いくつかの例は、XML の構文を示しています。複数のメソッドパーミッションステートメントが存在する可能性があり、それらのステートメントには累積的影響があります。< ;method-permission> 要素は、< ejb descriptor> 要素の子です。
-jar> 記述子の <assembly -
XML 構文は、EJB メソッドパーミッションのアノテーションを使用する代わりになります。
例9.5 ロールによる EJB のすべてのメソッドへのアクセスの許可
<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>
<ejb-name>EmployeeService</ejb-name>
<method-name>*</method-name>
</method>
</method-permission>
<method-permission>
<description>The employee and temp-employee roles may access any method
of the EmployeeService bean </description>

<role-name>temp-employee</role-name>
<method>
<ejb-name>EmployeeService</ejb-name>
<method-name>*</method-name>
</method>
</method-permission>
例9.6 ロールによる EJB の特定のメソッドのみへのアクセスを許可し、どのメソッドパラメーターを渡すかを制限します。

<method-permission>
<description>The employee role may access the findByPrimaryKey,
getEmployeeInfo, and the updateEmployeeInfo(String) method of
the AcmePayroll bean </description>

<method-name>findByPrimaryKey</method-name>
</method>
<method>

<method-name>updateEmployeeInfo</method-name>
<method-params>
<method-param>java.lang.String</method-param>
</method-params>
</method>
</method-permission>
例9.7 認証されたユーザーが EJB のメソッドにアクセスできるようにします。
<
unchecked/ > 要素を使用すると、認証されたユーザーが指定されたメソッドを使用できます。
<method-permission> <description>Any authenticated user may access any method of the EmployeeServiceHelp bean</description> <unchecked/> <method> <ejb-name>EmployeeServiceHelp</ejb-name> <method-name>*</method-name> </method> </method-permission>

EmployeeServiceHelp bean</description>
<unchecked/>
<method>
