En principio, seria esta parte: Using the HttpResponse’s PrintWriter, create a navigational menu along the top that includes links to the following pages (created in subsequent exercises): ● <a href=’CustomerDetails’>Customer Details</a> ● <a href=’CustomerController’>All Customers</a> ● <a href=’Stocks.jsp’>Stocks</a> ● Attempt to get a request attribute of type Customer from the HttpServletRequest by looking up the attribute named customer (case sensitive). A Customer object will be placed in the request scope by the servlet created in the next exercise. ● Create a form for a customer’s details. The default values for the form elements should be equal to the data in the Customer object if it was found in the request scope. The form can be laid out using any method you want, such as tables or CSS. The form should have the following properties: ● The action should be CustomerController. ● The method should be GET.

Use the getId method of the Customer to retrieve an ID that is passed as an HTTP GET form parameter to the PortfolioController development in the next exercise. Use the following example: “<a href=’PortfolioController?customerIdentity=” + id + “‘>View Portfolio</a>” ● Using an if statement, attempt to retrieve a String attribute named message (case sensitive), from the HttpServletRequest. This message is created by other classes when errors occur. Display the message string in red below the customer details form. ● Close the PrintWriter.
