I have installed Eclipse Java EE Luna Release (4.4.0) and App Engine SDK 1.9.10
I have created a new Google - Web Application Project and selected the Generate Project Sample Code option. I changed nothing about the project.
The generated project successfully deploys and runs locally. However when I deploy this to AppSpot I get an error message "Remote Procedure Call - Failure" when clicking on the "Send" button on the sample form.
Are there other steps I need to perform in order for the generated project to be successfully deployed to AppSpot?
My goal is to have a starting application that deploys so I can start learning to use Objectify and GWT to build applications. If there is a better way to go about this please suggest it.
Kind regards
Sean
I think seem to remember that sample code for the GWT builds a RPC-based HelloWorld or greeting example. In the auto-generated sample interface you type a name, a RPC call is made to server side and you get "Hello"+yourName or similar as a callback.
Check this link:
http://www.gwtproject.org/doc/latest/tutorial/appengine.html
This is a more advanced app, StockWatcher, from the GWT tutorials which is also RPC based and adapted for the GAE. You could start here: http://www.gwtproject.org/doc/latest/tutorial/gettingstarted.html to build this app (is really easy) and follow to the link above to deploy StockWatcher on the GAE, or check directly the steps on the first link and try to deploy the GWT "Greetings" example.
If you have already tried this or you do and there's still a problem, please provide the full stack trace, or the code you think might be causing the problem, so we have a better insight of the problem.

I am trying to develop my first web-application based on java-EE. This application should be deployed on WildFly application server. For That purpose, I made my inspiration from https://bitbucket.org/lassitercg/example/src.
I made some modifications on my Code.
I am developing this application using IntelliJ-Community. The Application was successfully deployed.
whenever I try to access the application using the following URL localhost:8080/startweb, I get the http status code 404. The code can be found unter this link https://github.com/amitakCsNew/startweb
Since I using Intellij Community edition, I am forced to deploy the application then set the breakpoint in the Controller of the application. The application seems to be succesfully deployed, but I am not jumping to the first breakpoint.
any Idea how I can solve this problem ?
Your webapp layout is wrong. Please refer to the standard Maven directories layout.
You need to move webapp directory to src/main. Then update pom.xml file reference to web.xml, then move META-INF from resources into webapp then fix your syntax errors in index.xhtml (the same h namespace is associated with 2 different URLs), then fix/implement your database, then add faces servlet in web.xml, add faces-config.xml, then your web app should be available at http://localhost:8080/startweb/.
Once you resolve all the problems and the controller code finally executes, you will be able to debug it from the IDE using Remote debug configuration.
If you are new to all of this, I'd suggest starting with something more simple, like a single JSP page and a single Java servlet.
Post the new questions if you have issues describing what you did to solve the problem and what exactly didn't work. The current question is too broad and your sample project has too many issues to cover in the single answer.
I've found a few post on this topic but have not been able to find the best solution.
Attempted to integrate Ionic into IBM MobileFirst (Worklight).
At the moment - I have built a normal Ionic project and moved the WWW folder in the 'common' folder. Also added in the initOptions, main.js and messages.js.
MobileFirst has an awful build process - I hate having to deploy to a mobilefirst development server + preview app for any code changes. I am hoping to get some type of auto reload working within mobileFirst, or at least develop with ionic normally and hav ea job to bring my changes into my worklight project... something that is better than me current situation.
Does anyone have a sample project that actually auto-builds or picks up code changes automatically?
Any and all help is greatly appreciated.
Not sure what do you mean by "auto-reloading"; if you make any changes to the web resources to your project inside the Studio plug-in (in Eclipse) and reload the preview in the browser, it will show the changes.
You are not required to Run As > Run on MobileFirst Development Server for each change. As long as you work on the resources in your workspace, the "auto-reloading" as you call it, should work (make sure you are using the latest available MobileFirst Studio version from the Eclipse Marketplace).
There is also a rudimentary Starter Application that is based on Ionic.
You can download it from here.
There are also several results on the subject matter when searching in Google.
The need to rebuild in order to see changes in your Web components (CSS, JavaScript, HTML) did used to be an annoyance in early versions of what was then Worklight and is now MobileFirst. I forget when the need for a rebuild was removed but certainly in Worklight 6.2 and beyond you now simply need to refresh in your browser.
UPDATE: If using MobileFirst 6.3 you need to ensure that you are on a
suitable patch level. I find that simple refresh does not work in
6.3.0.00-20150106-1717, but if I update (Help->Check for Updates) to 6.3.0.00-20150214-1702 then edit/save/refresh works as
expected.
My personal practice is always to have Mobile Web environment in my project and then choose that from the Console. This loads the application in the browser-based Mobile Simulator that you can tailor to fit your target form-factor. This has a "Go/Refresh" button that immediately reflects your edits.
Alternatively, some folks these days do not use Studio, instead they use the Command Line Interfacer. Possibly this may be more to your taste. You can download it here.
there is a solution with using staff like ionic-cli serve command + symbolic links that will replace common folder.
check here an example https://www.dropbox.com/s/4pvaulo6yo47kb9/lab_7.2.mp4?dl=0
(you just can disable sound, cause i've recorded it in russian) 7-15 minutes of this video
Other option is to organize live-preview yourself using IDE features and/or nodejs
This will work as long as you are working on front-end (mostly non-worklight api) part.
You need to include this lines in the index.html
<!-- ionic bundle & css -->
<link href="www/ionic/css/ionic.css" rel="stylesheet">
<script src="www/ionic/js/ionic.bundle.js"></script>
This may be a vague question but I have been unable to find any help/tutorials specific to my situation and am stuck.
I have built a website using Eclipse (Dynamic Web Project.) I then deployed this application using Tomcat and can see it by going to localhost, however, I am struggling on how to actually deploy it to the cloud.
I am trying to use Google App Engine but am open to other (free) alternatives for deploying my web application.
With Google App Engine, I registered for an account, made a new project, connected it to my github repository and confirmed the correct code is listed.
However, when navigating to project_id.appspot.com (mine is http://mapp-development.appspot.com) I get a 404 error.
I have attempted various deployments and even made an entirely new Google Web Application Project in Eclipse for testing which worked but weirdly deployed to http://1-dot-mapp-develop.appspot.com/ and is the test files which I do not know how to correctly modify.
Is there any way to upload/deploy my existing web application to Google App Engine (as a .war or otherwise)?
I am new to web development and apologize for any unclear specifications. Any help would be greatly appreciated!
Edit: I have also tried (in Eclipse) right clicking the project and choosing "Deploy to App Engine" under Google however it states "mapp-website is not an App Engine project".
Edit2: I had a stupid mistake, I confused my Project ID (mapp-development) and app id (mapp-develop). I am able to successfully make a new Google web project and deploy it to mapp-develop.appspot.com
Sorry for the trouble!
Here are three ways to deploy:
Make an App Engine project in Eclipse
Deploy via Git
Deploy via GitHub
It seems like you tried #1 with a project named 1-dot-mapp-develop. If you select deploy from Eclipse, a dialog box will pop up with a link to "App Engine Project Settings" where you can change the project name (to mapp-development and version).
I've always used eclipse before, but I'm using Netbeans for the first time because of it's integration with Web Service clients.
However, after following multiple tutorials, the way to add a web service client is to:
https://netbeans.org/kb/docs/websvc/flower_swing.html
Make a new project
Right click on your project, New->Other->Other->Web Service Client
However, I do not have the web service client option available, not sure what I am doing wrong.
Please mention the net beans version you have. You should use newer version of the IDE to use latest features.
For other developers who will face this problem like me, I will leave my answer here.
I'm currently using Apache NetBeans IDE 11.0 and it's in Web Services -> Web Service Client. If you still cannot find it, just use filter feature. I found it with filter.
i have installed the glassfish eclipse tools bundle...
i can start a project like dynamic web & a ear project and deploy them on the glassfish... it works perfect & under the localhost url i will get an hello world
but how i do this if i want to make an application client. please help...
at the moment i simply created an "app client project in eclipse" & added it to the same ear,
but i have no idea how to start this...
help - any tutorial how to start?!!
Not the only only answer to this question but the appclient approach mentioned in Jeff's answer is a viable approach, but I was able to execute a client using this mechanism in eclipse and I wanted to share that approach.
This approach will let you execute a java application with a main method acting as a client.
What you want to do is setup an External Tools Configuration.
Create a new Program type of external tool configuration.
Set location to point to the path of the appclient, for me
(using embedded glassfish eclipse plugin) it was [PATH TO ECLIPSE]\plugins\oracle.eclipse.runtime.glassfish_3.1.1.0\glassfish3\glassfish\bin\appclient.bat
Set working directory to your output/build directory e.g.
${project_loc}/target/classes
Set arguments to ${java_type_name}
Select the class in your project with a main method that you wish to run as the client app and then select your external tool from the run external tools menu.
There are two ways to do it. I'm afraid I can't be very specific, but I can point you in the right direction. (I'm just learning myself)
You can enable Web Start for the application client EAR in GlassFish. You can do this either in the deployment descriptor (so it's enabled every time you deploy) or you can go into the GlassFish admin console, navigate to the Application, and check the checkbox to enable it. I have made a little progress on this approach.
You can run it manually from the command line using, I believe, the "appclient" command. I have not been able to get this working yet.
Good luck, and if you learn more, I'd appreciate it if you let me know since I'm in the same boat as you.
