If you are serving your web app in a path other than the root, change
the href value below to reflect the base path you are serving from.
The path provided below has to start and end with a slash "/" in order
for it to work correctly. Fore more details: *

I wrote a simple SAPUI5 application and deployed it on our ABAP server with help of this blog entry.
It's working fine when the application is running on Tomcat. When I try to launch the application from the ABAP server, however, I get the following error:
I guess it has something to do with the name for the resources but I don't really understand it. The debugger points to the line where I call the index.js file:
data-sap-ui-oninit="module:hendrik/odatabench/index"
Here is the code of my index.html:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta http-equiv='Content-Type' content='text/html;charset=UTF-8'/>
<script src="resources/sap-ui-core.js"
id="sap-ui-bootstrap"
data-sap-ui-libs="sap.m"
data-sap-ui-theme="sap_bluecrystal"
data-sap-ui-compatVersion="edge"
data-sap-ui-async="true"
data-sap-ui-resourceroots='{
"hendrik.odatabench" : "./"
}'

</script>
</head>
<body class="sapUiBody" role="application">
<div id="content"></div>
</body>
</html>
Bootstrapping with the attribute sap-ui-oninit='module:...' is supported only as of UI5 1.54 (commit).
UI5 1.28 is quite an ancient version which is out of maintenance. Either update SAPUI5 library in your ABAP system or bootstrap the application by getting the UI5 resources from the CDN:
<script id="sap-ui-bootstrap"
src="https://ui5.sap.com/<version>/resources/sap-ui-core.js"
data-...
></script>
List of currently supported versions can be found here: https://ui5.sap.com/versionoverview.html
This is driving crazy. Have a simple Wordpress blog. Ran an audit using the Lighthouse tool in web developer tools of Chrome. For the area of Progressive Web App my score is an abysmal 53 with the following three errors. I can't figure out how to fix these errors.
Does not respond with a 200 when offline.
User will not be prompted to Install the Web App
Failures: Manifest's display value is not one of: minimal-ui | fullscreen | standalone, Site does not register a service worker.
Does not register a service worker.
The service worker is the technology that enables your app to use many Progressive Web App features, such as offline, add to homescreen, and push notifications.
Here is my manifest.json file. I change URL to example.com. And I know for a fact it's reachable on the server by going to the example.com/manifest.json and that is how it is called in the header as well. Am I missing anything in my manifest to cause these errors?
{
"name": "My Site",
"short_name": "My Site",
"theme_color": "#ffffff",
"background_color": "#082953",
"display": "browser",
"Scope": "/",
"start_url": "https://www.example.com",
"icons": [
{
"src": "/android-chrome-192x192.png",
"sizes": "192x192",

{
"src": "/android-chrome-512x512.png",
"sizes": "512x512",
"type": "image/png"
}
],
"splash_pages": null
}
Here is my generated header from home page. Not sure if I need all these icons. A bit confused as Lighthouse says a 512x512 is needed for manifest, but realfavicongenerator and other manifest generators don't seem to produce a 512x512 so I just made one in Photoshop and uploaded to root with the rest of the icons, then added the extra code to the manifest.json file.

This can be considered an error depending on whether you are making your blog available offline or not. Do you want your blog to be PWA, if yes then this all errors need to be handled otherwise you can just ignore them. Following is the explanation of errors.
Does not respond with a 200 when offline-
Progressive web apps work offline. If Lighthouse does not receive an HTTP 200 response
when accessing a page while offline, then the page is not accessible offline.
User will not be prompted to Install the Web App-
This is the feature which is available for PWA where you have service worker installed
and manifest is provided so that a web app is created on your phone's home screen.
Does not register a service worker-
This is the first thing you need to do for a PWA."To register a service worker".
You can uncheck progressive web app in audits and then calculate your score.
Now, lighthouse will not check for PWA compatibility and will not give any errors to it.
I am new in this Ionic field. I created a new app in my localhost folder(C:\xampp\htdocs). When I go to "http://localhost/ionapp/www/" everything works fine but when I run the app from "ionic serve" command I get the blank page.
When I viewed the page source I found that ionic.css and ionic.bundle.js file are not loaded during ionic serve. And in the console I get the error like "angular is not defined". Can anyone please help me fix this?
Here is my index.html which should load css and js files
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">

<link href="lib/ionic/css/ionic.css" rel="stylesheet">
<link href="css/style.css" rel="stylesheet">
<!-- IF using Sass (run gulp sass first), then uncomment below and remove the CSS includes above
<link href="css/ionic.app.css" rel="stylesheet">
-->
<!-- ionic/angularjs js -->
<script src="lib/ionic/js/ionic.bundle.js"></script>
<!-- cordova script (this will be a 404 during development) -->
<script src="cordova.js"></script>
<!-- your app's js -->
<script src="js/app.js"></script>
<script src="js/controllers.js"></script>
<script src="js/services.js"></script>
</head>
<body ng-app="starter">
<!--

-->
<ion-nav-bar class="bar-stable">
<ion-nav-back-button>
</ion-nav-back-button>
</ion-nav-bar>
<!--
The views will be rendered in the <ion-nav-view> directive below
Templates are in the /templates folder (but you could also
have templates inline in this html file if you'd like).
-->
<ion-nav-view></ion-nav-view>
</body>
</html>
So it was not the issue with my ionic but with my browser. Turns out I was getting ERR_CONNECTION_RESET in my console. So basically what I did was
Open cmd prompt as administrator.
Run the command netsh winsock reset.
Restart my computer.
I don't know how it happened but it solved all my problems.

Try to build package using Visual Studio with DevExtreme installed.
It allows to build native packages for all supported platforms (ios, android, windows phone).
Check out following link
http://help.devexpress.com/DevExtreme/Documentation/Howto/Packaging
If package will be built ok with DevExtreme, then your app is ok, and the problem with the way you do packaging. Will be glad to help you, just try and report the results.
I've read this and decided to rename my gwt-module, but got a fault. IDEA automaticaly generates test.gwt.xml when I create GWT-module project. It put:
<module rename-to="test">
inside test.gw.xml. If I remove "rename-to ..." and run app, GWT-plugin gives me an error. It seems to be nesessary in gwt.xml. It is contradictional with "Renaming Modules" part of article. Why can't I remove or rename?
Here is test.gwt.xml:
<!DOCTYPE module PUBLIC "-//Google Inc.//DTD Google Web Toolkit 2.0//EN"
"http://google-web-toolkit.googlecode.com/svn/releases/2.0/distro-source/core/src/gwt-module.dtd">
<module rename-to="test2">
<inherits name='com.google.gwt.user.User'/>
<entry-point class='com.ibm.temp.client.test'/>
<servlet path='/testService' class='com.ibm.temp.server.testServiceImpl'/>
</module>
And test.html:
<html>
<head>
<title>Wrapper HTML for App</title>
<link type="text/css" rel="stylesheet" href="test.css">
<script type="text/javascript" language="javascript" src="com.ibm.temp.test/com.ibm.temp.test.nocache.js"></script>
</head>
<body>
<h1>Simple Application</h1>
<div id="input-container"/>
</body>
</html>
Change script tag like this.The problem is that ur browser cannot find the nocache.js file.
If module rename to abc , nocache.js will be in war/abc/abc.noacache.js
If module not renamed,it will be in war/full package name of gwt.xml/full package name.nocache.js
For your case it will be as,
<script type="text/javascript" language="javascript" src="test2/test2.nocache.js"></script>
