I'm using custom.jsp in order to avoid the login screen and load the home screen directly, but still it's asking for login credentials after restarting the tomcat. The path of the custom.jsp file is "SAP BusinessObjects\tomcat\webapps\BOE\WEB-INF\eclipse\plugins\webpath.InfoView\web"
I don't know what I'm missing here and I'm new to this. Below is my jsp code. Thanks.

The Problem is that when i try to print the results in DB_results.jsp using variable myRs, myRs == NULL. Why is this happening? I'm using Tomcat-Apache 8.0.
You never call setMyRS(). And even if you did, setMyRS() iterates through the resultset, so myRs.next() would always return false in the JSP.
Im working on a DynamicWebProject in Eclipse IDE.I got an error in console while running a jsp page showing "Failed to load resource: the server responded with a status of 404 (Not Found)".I already referred many questions regarding this problem but could not resolve it.Here is my javascript file
availability.js
var ajaxRequest = null;
if (window.activeXObject) {
ajaxRequest = new ActiveXObject("Microsoft.HTTP");
} else {
ajaxRequest = new XMLHttpRequest();
}
function ajaxValidation() {
var name = document.getElementById("username").value;
ajaxRequest.open("GET", "/SpringHibernateProject/validate?name=" + name,
true);
ajaxRequest.onreadystatechange = function() {
if (ajaxRequest.readyState == 4 && ajaxRequest.status == 200) {
var message = ajaxRequest.responseText;
document.getElementById("div").innerHTML = "<font color='red'>"
+ message + "</font>";
}
};
ajaxRequest.send(null);
}
Here is my jsp page
AjaxPage.jsp
<%# page language="java" contentType="text/html; charset=ISO-8859-1"

Im getting this error though I referred the script file correctly.Why is it so?

Images are loaded as separate requests to the request that loaded the html. As such you need to:
establish a URL encoding scheme that you use when specifying the src of the img element.
map a servlet (or similar) to that URL. The servlet loads the image based on the parameters of the URL returning that image in its response.
I found out.
