Custom disposition example

Starting with version 3.0, if you don't want to use the default generic UI (e.g. for some of your users) you can develop a custom disposition.

The authentication mechanism will remain the same but, once connected, the user will get a custom UI built by a server side script (by implementing the <Disposition name>.display function which can using associated resources if required).

In the example below we will implement a basic single page Bootstrap®-based custom UI that uses the Ajax API within a client-side JavaScript resource. The name of this example disposition is MyDisp.

Server side script

In the example, the server side script just builds the static parts of the disposition page (including the main div which will be used by the client side script):

Java

import com.simplicite.webapp.HTMLPage;
import com.simplicite.webapp.web.BootstrapWebPage;
@Override
public String display(Parameters params) {
	Grant g = getGrant();
	BootstrapWebPage wp = new BootstrapWebPage(params.getRoot(), g.getParameter("WINDOW_TITLE", "Simplicité"));
	wp.appendAjax();
	wp.appendJSInclude(HTMLPage.getResourceJSURL(g, "SCRIPT")); // Include a client side JavaScript
	wp.appendCSSInclude(HTMLPage.getResourceCSSURL(g, "STYLES")); // Include a custom stylesheet
	wp.setFavicon(HTMLPage.getResourceIconURL(g, "FAVICON"));
	wp.setReady("mydisp(\"" + wp.getRoot() + "\");");
	
	LinkedHashMap sm = new LinkedHashMap();
	sm.put("submenu1", "My sub menu 1");
	sm.put("submenu2", "My sub menu 2");
	LinkedHashMap m = new LinkedHashMap();
	m.put("menu1", "My menu 1");
	m.put("menu2", wp.subMenu("menu2", "My menu 2", sm));
	m.put("quit", "<span class=\"glyphicon glyphicon-off\"></span> " + g.T("QUIT"));
	wp.setMenu("home", "<img src=\"" + HTMLPage.getResourceImageURL(g, "LOGO") + "\" style=\"margin: 5px;\"/>", m, false, true, true);
	
	wp.appendHTML("<div id=\"main\"></div>");
	
	wp.appendHTML("<div id=\"footer\">&copy; Simplicité Software</div>");
	
	return wp.toString();
}

As of version 3.1 MAINTENANCE 08, the displayPublic, displayPublicHome, displayHome, displayLogon and displayLogout functions can be used on the same principle to override the public main page, public home page, authenticated home page, logon page and logout page when needed.

For instance to override the default logon script with a Bootstrap® page, you can implement the displayLogon function as:

Java

import com.simplicite.webapp.HTMLPage;
import com.simplicite.webapp.web.BootstrapWebPage;
@Override
public String display(Parameters params) {
	Grant g = getGrant();

	BootstrapWebPage wp = new BootstrapWebPage(params.getRoot(), g.getParameter("WINDOW_TITLE", "Simplicité"));
	
	wp.appendJSInclude(HTMLPage.getResourceJSURL(g, "SCRIPT"));
	wp.appendCSSInclude(HTMLPage.getResourceCSSURL(g, "STYLES"));
	wp.setFavicon(HTMLPage.getResourceIconURL(g, "FAVICON"));
	
	wp.append(HTMLPage.getResourceHTMLContent(g, "LOGON"));
	wp.setReady("loaded();");
	
	return wp.toString();
}

The disposition LOGON HTML resource being:

<div class="panel panel-default" style="margin-top: 50px;">
	<div class="panel-heading text-center">
		![](https://www.simplicite.io/logos/logo.svg)
	</div>
	<div class="panel-body">
		<form role="form" method="post" action="j_security_check">
			<div class="form-group">
				<label for="login">Login:</label>
				<input type="text" class="form-control" id="login" name="j_username">
			</div>
			<div class="form-group">
				<label for="pwd">Password:</label>
				<input type="password" class="form-control" id="pwd" name="j_password">
			</div>
			<button type="submit" class="btn btn-default">OK</button>
		</form>
	</div>
</div>
<script>
function loaded() {
	$("#login").focus();
}
</script>

Client side resources

The client side JavaScript SCRIPT resource uses the Ajax API to dynamically build the main div content:

function mydisp(root) {
	var app = new Simplicite.Ajax(root);
	home();
	
	$("#home").click(function() { home(); });
	$("#menu1").click(function() { alert("You clicked menu 1 !"); });
	$("#submenu1").click(function() { alert("You clicked sub menu 1 !"); });
	$("#submenu2").click(function() { alert("You clicked sub menu 2 !"); });
	$("#quit").click(function() { document.location.replace("../logout.jsp"); });

	function loading() {
		$("#main").empty().append($("<img/>", { src: "../images/image/inprogress.gif" }));
	}
	
	function home() {
		loading();
		app.getGrant(function() {
			$("#main").empty().append("Hello " + app.grant.login + " !");
		});
	}
}

And the CSS STYLES resource could be something like:

#main { padding: 10px; border-radius: 5px; background-color: #F7F7F7; }
#footer { margin-top: 25px; border-top: solid 2px #F0F0F0; }
