Given the security constraint in a DD：
101.<security-constraint>
102.<web-resource-collection>
103.<web-resource-name>Foo</web-resource-name>
104.<url-pattern>/Bar/Baz/*</url-pattern>
105.<http-method>POST</http-method>
106.</web-resource-collection>
107.<auth-constraint>
108.<role-name>DEVELOPER</role-name>
109.</auth-constraint>
110.</security-constraint>
And given that "MANAGER" is a valid role-name，which four are true for this security constraint？（）
A.MANAGER can do a GET on resources in the /Bar/Baz directory.
B.MANAGER can do a POST on any resource in the /Bar/Baz directory.
C.MANAGER can do a TRACE on any resource in the /Bar/Baz directory.
D.DEVELOPER can do a GET on resources in the /Bar/Baz directory.
E.DEVELOPER can do only a POST on resources in the /Bar/Baz directory.

23.if（req.isUserInRole（"Admin"）） {
24.// do stuff
25.}
And the following fragment from the related Java EE deployment descriptor：
812.<security-role-ref>
813.<role-name>Admin</role-name>
814.<role-link>Administrator</role-link>
815.</security-role-ref>
900.<security-role>
901.<role-name>Admin</role-name>

Your IT department is building a lightweight Front Controller servlet that invokes an application logic objectwith the interface：public interface ApplicationController {public String invoke（HttpServletRequest request）}The return value of this method indicates a symbolic name of the next view. From this name， the FrontController servlet looks up the JSP URL in a configuration table. This URL might be an absolute path or apath relative to the current request. Next， the Front Controller servlet must send the request to this JSP togenerate the view. Assume that the servlet variable request is assigned the current HttpServletRequestobject and the variable context is assigned the webapp’s ServletContext.Which code snippet of the FrontController servlet accomplishes this goal？（）
