help java web ______--_________ Identify the technique that can be used to implement 'sessions' if the client browser does not supportcookies. (Choose one)A. URL rewritingB. It cannot be done without cookie support.C. Using Http headers.Given the following deployment descriptor:jdbcDriversun.jdbc.odbc.JdbcOdbc DriverInitParamsInitParams ServletWhat is the outcome of running the following servlet? (Choose one.)public class InitParams Servlet extends HttpServlet {protected void doGet(HttpServletRequest request, HttpServletResponse response) throwsServletException, IOException {ServletContext sc=this.getServletContext();Print Writer out = response.getWriter();out.write("Initialization Parameter is: " + sc.getInitParameter("jdbc Driver"));A. A runtime errorB. "Initialization Parameter is: sun.jdbc.odbc.JdbcOdbcDriver" returned to the requesterC. "Initialization Parameter is: null" returned to the requester Which statements are BEST describe pageContext implicit object of jsp file?A. This javax.servlet jsp.JspWriter object writes text as part of the response to a request. This object is usedimplicitly with JSP expressions and actions that insert string content in a response.B. This java.lang.Object object represents the this reference for the current JSP instance,C. This javax.servlet.jsp PageContext object hides the implementation details of the underlying servlet andJSP container and provides JSP programmers with access to the implicit objects discussed in this tableD. This object represents the response to the client. The object normally is aninstance of a class that implements HttpServletResponse (package javax.servlet.http). If a protocol other thanHTTP is used, this object is an instance of a class that implements javax.servlet.ServletResponse.E. This object represents the client request. The object normally is an instance of a class that implementsHttpServletRequest (package javax.servlet.http). If a protocol other than HTTP is used, this object is aninstance of a subclass of javax.servlet.ServletRequest.
