第3题：

Servlet A receives a request that it forwards to servlet B within another web application in the same webcontainer. Servlet A needs to share data with servlet B and that data must not be visible to other servlets inA’s web application. In which object can the data that A shares with B be stored？（）

第4题：

A developer has created a special servlet that is responsible for generating XML content that is sent to adata warehousing subsystem. This subsystem uses HTTP to request these large data files， which are compressed by the servlet to save internal network bandwidth. The developer has received a request frommanagement to create several more of these data warehousing servlets. The developer is about to copyand paste the compression code into each new servlet. Which design pattern can consolidate thiscompression code to be used by all of the data warehousing servlets？（）

• A、Facade
• B、View Helper
• C、Transfer Object
• D、Intercepting Filter
• E、Composite Facade

第5题：

Which is the true choice about the web container request processing model（）？

• A、 The init method on a filter is called the first time a servlet mapped to that filter is invoked
• B、 A filter defined for a servlet must always forward control to the next resource in the filter chain.
• C、 Filters associated with a named servlet are applied in the order they appear in the web application deployment descriptor file
• D、 If the init method on a filter throws an UnavailableException， then the container will make no further attempt to execute it

第6题：

Your web application uses a simple architecture in which servlets handle requests and then forward to aJSP using a request dispatcher. You need to pass information calculated by the servlet to the JSP；furthermore， that JSP uses a custom tag and must also process this information. This information mustNOT be accessible to any other servlet， JSP or session in the webapp. How can you accomplish this goal？（）

• A、Store the data in a public instance variable in the servlet.
• B、Add an attribute to the request object before using the request dispatcher.
• C、Add an attribute to the context object before using the request dispatcher.
• D、This CANNOT be done as the tag handler has no means to extract this data.

第7题：

Which three are described in the standard web application deployment descriptor？（）

• A、session configuration
• B、MIME type mappings
• C、context root for the application
• D、servlet instance pool configuration
• E、web container default port bindings
• F、Servlet Context initialization parameters

第8题：

• A、REQUEST_URI
• B、javax.servlet.forward.request_uri
• C、javax.servlet.forward.REQUEST_URI
• D、javax.servlet.request_dispatcher.request_uri
• E、javax.servlet.request_dispatcher.REQUEST_URI

第9题：

Which interface must a session attribute implement if it needs to be notified when a web container persistsa session？（）

• A、javax.servlet.http.HttpSessionListener
• B、javax.servlet.http.HttpSessionBindingListener
• C、javax.servlet.http.HttpSessionAttributeListener
• D、javax.servlet.http.HttpSessionActivationListener

第10题：

Your web application uses a simple architecture in which servlets handle requests and then forward to aJSP using a request dispatcher. You need to pass information calculated in the servlet to the JSP for view generation.This information must NOT be accessible to any other servlet，JSP or session in the webapp. Which two techniques can you use to accomplish this goal？（）

• A、Add attributes to the session object.
• B、Add attributes on the request object.
• C、Add parameters to the request object.
• D、Use the pageContext object to add request attributes.
• E、Add parameters to the JSP’s URL when generating the request dispatcher.
