One of the use cases in your web application uses many session-scoped attributes. At the end of the use case, you want to clear out this set of attributes from the session object. Assume that this static variable holds this set of attribute names:

201.

private static final Set USE_CASE_ATTRS;

202.

static {

203.

USE_CASE_ATTRS.add("customerOID");

204.

USE_CASE_ATTRS.add("custMgrBean");

205.

USE_CASE_ATTRS.add("orderOID");

206.

USE_CASE_ATTRS.add("orderMgrBean");

207.

}

Which code snippet deletes these attributes from the session object?

A. session.removeAll(USE_CASE_ATTRS);

B. for ( String attr : USE_CASE_ATTRS ) {session.remove(attr);}

C. for ( String attr : USE_CASE_ATTRS ) {session.removeAttribute(attr);}

D. for ( String attr : USE_CASE_ATTRS ) {session.deleteAttribute(attr);}

E. session.deleteAllAttributes(USE_CASE_ATTRS);

C. The true element must appear in the echo tag TLD.

D. The class implementing the echo tag handler must implement the javax.servlet.jsp.tagext.IterationTag interface.

B. The body of the tag may contain EL code, but not scripting code.

C. When looping over collections, a loop status object may be used in the tag body.

D. It may iterate over a map, but only the key of the mapping may be used in the tag body.

You are creating a JSP page to display a collection of data. This data can be displayed in several different ways so the architect on your project decided to create a generic servlet that generates a comma-delimited string so that various

pages can render the data in different ways. This servlet takes on request parameter:

objectID. Assume that this servlet is mapped to the URL pattern: /WEB- INF/data.

In the JSP you are creating, you need to split this string into its elements separated by commas and generate an HTML

list from the data.

Which JSTL code snippet will accomplish this goal?

A.

• $ {item}

B.

• $ {item}

C.

• $ {item}

D.

• $ {item}
