大致意思是：服务器应用程序错误——该服务器遇到一个错误，同时装载在您的请求处理的申请。
The server has encountered an error while loading an application during the processing of your request.
如果应用程序服务器仍在运行，可能会向您显示图3中所示的先决条件错误消息。
If the application server is still running you might be presented with the perquisite error message shown in Figure 3.
但一旦将应用程序或服务器部署到生产环境之后，您应该禁用错误消息，或配置为仅显示常见信息。
But when you deploy your application or server into production, your error messages should be disabled or configured to reveal very generic information.
这个错误通常由基本连接失败引起，例如试图对安全应用程序服务器进行不安全的连接。
This error is usually caused by a basic connection failure, such as attempting to make a non-secured connection with a secure application server.
图6显示了应用程序服务器内此类错误的潜在影响。
Figure 6 illustrates the potential impact of such failures within the application server.
例如，使用前面已经完成的代码，如果您执行时在第一个jsp页面中输入值0，则将在应用程序服务器控制台上产生一个错误。
For example, with the code that has been completed so far, if you enter a value of 0 in the first JSP page during execution, an error message will be generated on the application server console.
在典型的错误中，一个企业选择群集它们的Web服务器和应用程序服务器而不是数据库服务器。
In the classic mistake, an enterprise chooses to cluster its Web servers and application servers but not the database servers.
管理员可能犯的最严重错误就是把服务器的所有资源如操作系统、第三方应用程序、页面空间以及应用程序数据等均置于单个卷组中。
The worst mistake an administrator can make is to put all of a server's resources—operating system, third-party applications, paging space, and application data—within a single volume group.
另一个CXF错误也出现在使用addBook 操作时，但这次是在请求失败时，返回的应用程序错误响应应该使用加密，但是 CXF 服务器发送它时不使用加密，而且客户端也毫无异议地接受了。
The other CXF error was the same as Axis2, not using encryption for the application fault response.
自动检测错误是否从过载应用程序中返回，并将下一个应用程序请求传送到另一个能够运行该应用程序的服务器。
Automatically detect that an error is being returned from an overloaded application and route future application requests to another server capable of running the application.
假定应用程序里面有一个偶然性的错误(例如一个发布数据库连接的失败)要求应用程序服务器每个月重启一次。
Assume the application will have an occasional bug in it (e.g. a failure to release database connections) that requires the application server to be restarted once a month.
每个人都知道如果打开一个并不存在的页面，服务器会返回一个404错误页面。如果你的Rails程序出错了，会返回一个500应用程序内部错误的页面。
Everyone knows that if you try to access a page that doesn't exist, the server will throw you back 404 page not Found, or if you mess up your rails code, you will get a 500 Application Error.
如果服务器堆大小的默认设置不够(即当您运行应用程序时会出现Out OfMemoryError错误)，您可能需要增加服务器堆大小。
If the default setting of the server's heap size is not sufficient (that is, when you get OutOfMemoryError when running the applications), you may want to increase the heap size of the server.
