The following is CheckAddress.jsp page which checks if the form has the name and phone fields filled in or not. If not then it must print the errors. But the problem I am having is that the Eclipse is showing me the error "JspWriter cannot be resolved to a type".
If I ignore this error and run the page in the j2ee preview server in eclipse than I get the following error:
>
