What is your context root? EMAIL_COMPONENT or EMAIL_COMPONENT/jsp?

How did you define the default page? MainPage.jsp or jsp/MainPage.jsp?

What URL are you using when making your AJAX call?

How are you building it?
Can you post the JSP code that is used to create the URL?

You're using a relative URL when making your AJAX call.

var url = "GetEmailsServlet.jsp?sender_email="+AJAX_FIELD.value; 

Like any link in a JEE app, the best approach is to make the link relative to the context path, not the current file.
Try:

var url = "${pageContext.request.contextPath}/GetEmailsServlet.jsp?sender_email="+AJAX_FIELD.value; 

Or, if you're using JSP 1.2:

var url = "<%=request.getContextPath()%>/GetEmailsServlet.jsp?sender_email="+AJAX_FIELD.value;
