You are building a web application that will be used throughout the European Union; therefore, it has significant internationalization requirements. You have been tasked to create a custom tag that generates a message using the java.text.MessageFormat class. The tag will take the resourceKey attribute and a variable number of argument attributes with the format, arg. Here is an example use of this tag and its output:

generates:

The disk "MyDisk" contains 1247 file(s).

Which Simple tag class definition accomplishes this goal of handling a variable number of tag attributes?

A. public class MessageTag extends SimpleTagSupportimplements VariableAttributes {private Map attributes = new HashMap();public void setVariableAttribute(String uri,String name, Object value) {this.attributes.put(name, value);}// more tag handler methods}

B. The Simple tag model does NOT support a variable number of attributes.

C. public class MessageTag extends SimpleTagSupportimplements DynamicAttributes {private Map attributes = new HashMap();public void putAttribute(String name, Object value) {this.attributes.put (name, value);}// more tag handler methods}

D. public class MessageTag extends SimpleTagSupportimplements VariableAttributes {private Map attributes = new HashMap();public void putAttribute(String name, Object value) {this.attributes.put (name, value);}// more tag handler methods}

E. public class MessageTag extends SimpleTagSupportimplements DynamicAttributes {private Map attributes = new HashMap();public void setDynamicAttribute(String uri, String name,Object value) {this.attributes.put(name, value);}// more tag handler methods}

For a given ServletResponse response, which two retrieve an object for writing text data? (Choose two.)

A. response.getWriter()

B. response.getOutputStream()

C. response.getOutputWriter()

D. response.getWriter().getOutputStream()

E. response.getWriter(Writer.OUTPUT_TEXT)

Which element of the web application deployment descriptor defines the servlet class associated with a servlet instance?

A.

B.

C.

D.

E.

F.

Assume the tag handler for a st:simple tag extends SimpleTagSupport. In what way can scriptlet code be used in the body of st:simple?

A. set the body content type to JSP in the TLD

B. Scriptlet code is NOT legal in the body of st:simple.

C. add scripting-enabled="true" to the start tag for the st:simple element

D. add a pass-through Classic tag with a body content type of JSP to the body of st:simple, and place the scriptlet code in the body of that tag

Given a Filter class definition with this method:

21.

public void doFilter(ServletRequest request,

22.

ServletResponse response,

23.

FilterChain chain)

24.

throws ServletException, IOException {

25.

// insert code here

26.

}

Which should you insert at line 25 to properly invoke the next filter in the chain, or the target servlet if there are no more filters?

A. chain.forward(request, response);

B. chain.doFilter(request, response);

C. request.forward(request, response);

D. request.doFilter(request, response);
