We will discuss JACC later in more detail .

我们稍后将对JACC进行更为详细的讨论。

See the JACC API Specification for more information on JACC .

有关JACC的更多信息，请参见JACCAPI规范。

Any JACC provider must satisfy the authorization requirements for all the applications in a cell .

任何JACC提供程序都必须满足计算单元内的所有应用程序的授权要求。

However , the JACC provider is not limited by the static nature of the standard J2EE security model .

不过，JACC提供程序并不仅限于标准J2EE安全模型的静态特性。

The JACC will continue to work with Malaysian authorities .

该中心将继续与马来西亚政府合作。

Prior to JACC , there was no specification to address the access decisions the application server makes .

在JACC之前，并没有针对应用服务器作出的访问决策的规范。

The JACC provider has the autonomy and information necessary to also make dynamic , run time-based access decisions .

JACC提供程序还具有进行动态的基于运行时的访问决策所必需的自主性和信息。

Let us now consider some caveats in the consideration of JACC , relating to performance and implementation complexity

现在，让我们了解一下在考虑JACC时需要注意的一些与性能及实现复杂性相关的事项

JACC provides the ability to delegate the permissions checking of security authorization to an external provider .

JACC提供了将安全授权的权限检查委托给外部提供程序的功能。

For example , WebSphere Application Server supports all of the policy context handlers that are required by the JACC specification .

例如，WebSphereApplicationServer支持JACC规范所要求的所有策略上下文处理程序。

The JACC provider is obliged to provide a concrete Policy sub-class , which implements the implies method .

JACC提供程序必须提供实现implies方法的具体Policy子类。

In the absence of JACC , vendor implementations and proprietary interfaces were used for third party vendor product integration .

在没有JACC的情况下，要使用供应商实现和专用接口进行第三方供应商产品集成。

Implementation of a JACC provider that extends the J2EE security model is a complex task and should not be undertaken lightly .

实现扩展J2EE安全模型的JACC提供程序是一项复杂的任务，不应轻视。

When a product provides both JACC and proprietary API-based solutions , it is important to understand the capabilities available in each model .

当产品同时提供JACC和基于专用API的解决方案时，务必了解每个模型中可用的功能。

As mentioned earlier , the JACC provider has access to this information and is fully able to support externalizing these access decisions .

正如前面所提到的，JACC提供程序可访问此信息，并全面支持这些访问决策的外部化。

Java ™ Authorization Contract for Containers ( JACC ) is a standards-based approach to integrating external security managers with an application server .

Java™AuthorizationContractforContainers（JACC）是一种基于标准的方法，用于将外部安全管理器与应用服务器集成。

Abbott said that the JACC will ensure that the search is reinforced by strong liaison with all the relevant stakeholders .

阿博特表示，联合协调中心将通过加强与各方联络、沟通，确保搜索行动继续加强。

JACC , on the other hand , is able to support the mapping described above , but also to support dynamic , instance-based access control as well .

而另一方面，JACC能够支持上述映射，而且还支持动态的基于实例的访问控制。

According to the JACC , the Australian Maritime Safety Authority has planned a visual search area totaling over 41 thousand square kilometers .

据联合协调中心消息，澳大利亚海上安全局计划当天在共计约41393平方公里的海域展开可视化搜索。

The original intent of JACC was to provide a standard interface to enable third parties to plug in authorization providers to make access decisions .

JACC最初的目的是为了提供一个标准接口，以便第三方能够插入授权提供程序来作出访问决策。

On the other hand , JACC does not supply support for performing non-standard permission checking , as would be required in extending the J2EE security model .

另一方面，JACC并未提供对执行非标准权限检查的支持，而扩展J2EE安全模型又将需要这种支持。

Let us consider how this maps to standard J2EE security , and then to JACC usage before we look at the trade-offs that come with JACC .

在讨论JACC带来的利弊前，让我们考虑如何将这种关系映射到标准J2EE安全性以及JACC使用。

To use the JACC interface today , you need to install a specific provider for the vendor of the security service , as the protocol from the provider to the service is undefined .

为了使用目前的JACC接口，您需要安装安全服务供应商的特定提供程序，因为并未定义从提供程序到服务的协议。

Earlier in the day , Australian Prime Minister Tony Abbott announced former Defense Force Air Chief Marshal Angus Houston will lead a new Joint Agency Coordination Center ( JACC ) based in Perth .

当天早些时候，澳大利亚总理托尼·阿博特宣布，将在珀斯建立一座新的联合协调中心，由前国防军空军上将安格斯·休斯敦将领导。

However , there are caveats when considering the use of JACC , and so it is necessary to take a closer look at JACC to understand exactly what it does and where it may be useful .

不过，使用JACC时有一些方面需要特别注意，因此有必要更深入地探讨JACC，以准确了解其执行的工作以及可对其加以应用的场合。

Within our JACC provider , we could provide a mapping table of EJBs , roles , operations , and objects ; for example , using the " Printer " EJB ," Managers " are able to " ManageQueue " on " PrinterX " .

在我们的JACC提供程序内部，可以提供一个EJB、角色、操作和对象的映射表；例如，通过使用“Printer”EJB，“Managers”能够对“PrinterX”执行“ManageQueue”操作。
