ejb-jar.xml中，role-name指的是什么??

[mypackage]

<assembly-descriptor>
<security-role>
<role-name>Employees</role-name>
</security-role>
<method-permission>
<role-name>Employees</role-name>
<method>
<ejb-name>CustomerEJB</ejb-name>
<method-name>*</method-name>
</method>
</method-permission>
<container-transaction>
<method>
<ejb-name>CustomerEJB</ejb-name>
<method-name>*</method-name>
</method>
<trans-attribute>Required</trans-attribute>
</container-transaction>
</assembly-descriptor>

其中role-name指的是什么？是weblogic的domain的role?
