I'm sorry for the stupid question.
I have Intellij Idea 13 and I created GWT template "MySampleApplication". If I try to run it I get this link:
http://127.0.0.1:8888/MySampleApplication.html?gwt.codesvr=127.0.0.1:9997
I open it in browser and it offers me to install developer plugin. I know that this plugin is up to date and not working. So how can I run this application? Using Super Dev Mod? SDM opens just code server page http://localhost:9876/
P.S. "If you are a customer we will do everything for you. If you are a developer - shut up and do everything youself." Is it normal that there is no word about this in GWT tutorial? I'm angry.

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>
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.
On integrating a library on server side of my gwt app (maven, gwt 2.4) the development/hosted mode stopped working. The app works fine if deployed or run with "gwt:run" and all unit tests and integration tests pass as before.
If i start development mode (run/debug as web application) from Eclipse the develpoment mode view pops up but nothing else happens. normally the console should show some output but console keeps empty. So i don't even have a hint whats going wrong.
Can someone give some advice where to look / what to do to get at least a hint what's wrong?
if i check out the revision before integrating the library the development mode works! - at the moment i add the dependency (only adding not using it) it stops working.
Background about library i added (don't know if my problem relates to this):I had some problem on integrating the library. the library uses eclipse birt charting engine. This engine has a dependency to Apache derby db, this conflicted with another library. i solved this by excluding the derby dependency via maven. the second problem was a "command line too long" error on unit test - this was solved by updating the maven-surefire-plugin.
The Problem was hard but the solution is simple: With Java 7 it is working!
The problem could be reproduced on 2 of 3 machines. The machine without the problem is the only one that uses java 7. So i installed java 7 on my machine and linked eclipse to it - now hosted mode (from eclipse) works again :-).
I am using GWT 2.3.0 as a plugin for Eclipse to develop a web based application
Unfortunately, when I try to run my application I get:
plugin failed to connect to developer mode server at 127.0.0.1:9997
and
onModuleLoad() threw an exception :java.lang.reflect.InvocationTargetException
I have installed the Gwt developer plugin for Google Chrome and every time I run my project it requires me to install this plugin and restart the browser, after which I get the above mentioned problem.
You can solve this issue by:
Right click on your web project -> Run as -> Run configurations.
Select 'Server' and 'GWT' tabs respectively and check on 'Automatically select an unused port'
Clear Cache from your Chrome browser (do the same on Firefox if you are using Firefox, remember the GWT plugin is not available on the latest Firefox versions, 3-10 I believe).
Run and hopefully enjoy.
I know it's an old question but,
I ran into the same problem today.
For some reason (quite unknown to me) deleting the ":9997" from the end of the address fixed it, and the application came up nicely.
Hope this helps.
Look at http://notepad2.blogspot.com/2010/12/debug-google-web-toolkit-applications.html for a step by step instruction on how to set up chrome, particularly the last part on how to setup the plugin using an external web server.
For the first problem that you faced : plugin failed to connect to developer mode server at 127.0.0.1:9997 , just clear your browser cache and try once again.
Just happend to me today too, and I've managed to fix it:
It turns out that the set of the GWT modules to be loaded is configureable; by referring to one of the GWT html's from the browser, it appears I was actually trying to connect to a page under a module that has been removed from the run-config's modules list. So, one more thing to do is to verify the list's content:
In eclipse: "Run Configurations" > Web Application > (your app) > GWT tab > Available Modules
In IntelliJ (that's what I've used): Edit Configurations > (select your GWT config) > GWT Modules to load
The GWT Plugin may be need to restarted
First Clear Browser cash
Second : try the following on chrome browser
-
open : chrome://extensions/
Go to : GWT Developer Plugin
uncheck the Enabled box
check the Enabled box
Open URL again and have fun :)
I fixed the issue by only clearing the browser cache. I am working with Firefox 15.0.1
Ive installed the Google Plugin for Eclipse and created a demo project using App Engine and GWT. Now I want to launch and see it. But after compile nothing else happens. Shouldn't there be an integrated browser that shows the app?
You need to right click on the project name and hit run > web application. Compiling it is for deployment, and most likely not what your looking for from running. The key differences here are hosted mode handles the cross-compilation for you, while compiling is meant for deployment of the javascript to your web server.
As far as I know, you just point your browser (any browser) to http://localhost:8080. Is that not working for you?
I get it running externally on the command line with
dev_appserver .
or to upload to the google site
appcfg update .
for python they're .py files and for java their .cmd calls
wish I could mix and match my languages/GAE environments
You can right click your project and goto Run as > Web Application.
You can see that a local Jetty Server.
You can manually type the address http://localhost:8888 or you can access through cmd
