I started learning GWT and wrote a sample app in Eclipse. I then said "Run on server". It gave me a URL to open and I opened that in Chrome. I saw a prompt asking me to install the GWT Developer Plugin and gave me a link. But I don't see any button to "Install". Is this some cruel joke from Google? What am I supposed to do now? How do I run the app? Eclipse only gives me this link which in turn gives me a prompt to install the plugin which I can't. On Firefox, it says version 29 not supported. What the hell is going on?
GWT Developer Plugin isn't compatible to Firefox 27+. So it simply doesn't work with your FF 29.
The reason why it doesn't work anymore can be found in a post by Brian Slesinsky.
You have several options of how to work in the future:
Use FF 26 (this can cause potential security problems)
Use FF ESR version (currently based on FF 24) that is typically used by Companies
Use Super Dev Mode
Use Dev Mode with another supported browser (e.g. Internet Explorer) and test FF with a compiled version of your application only.

Hey so I have this IP printer that uses some java-applet to get it's work done, yet as of a few days ago, firefox dropped all support for npapi plugins but flash, hence java is no longer supported.... They have claimed to release some new distribution that would have extended support for java users... yet apparently this doesn't work for me.... any idea how to solve this and allow java support by my browser?
There's no hope for applets in the long run.
As for Firefox 52, you can add plugin.load_flash_only:false in about:config.
Or you can install Firefox ESR 52 to postpone the problem a bit longer.
Firefox
Open the Firefox browser or restart it, if it is already running
From the Firefox menu, select Tools, then click the Add-ons option
In the Add-ons Manager window, select Plugins
Click Java (TM) Platform plugin (Windows) or Java Applet Plug-in (Mac OS X) to select it
Check that the option selected is Ask to Activate or Always
Activate or on older Firefox versions, click on the Enable button (if the button says Disable, Java is already enabled)
So, I'm trying to set up a project using GWT with Eclipse Mars.2, I'm following the intructions in the GWT Eclipse config page, but when it comes time to run in development mode, my browser says it doesn't have the GWT Developer Plugin. Problem arises when I try to install it, as Firefox only has support for this plugin until FF26(and I'm on 47), and Chrome has no support for NPAPI plugins anymore, and so I can't download this plugin from the google store.
I don't really know how to go on from here, is there another way to install the GWT plugin, or is there an alternative for it? Thanks.
devmode has been deprecated for quite a while now, and GWT 2.7's DevMode defaults to using superdevmode. devmode will actually be removed entirely after GWT 2.8.
SuperDevMode can be used starting with GWT 2.5 but is really usable only from GWT 2.7, where it's also easier to use (just refresh the page, like in legacy devmode).
So, you should upgrade to GWT 2.7 if you haven't already, and use SuperDevMode from now on.
I am new to javacard applet development.How many development tools are there now? Which is the simplest for beginners? As simple as possible...
Thanks in advance
There is a development kits called JCIDE, is free. After installation, can be used directly, no configuration parameters. Unfortunately, when debugging, only set one breakpoint, but normal use is enough. I feel very good, recommended to you.
Here's a ready made set of applets that you can use with standard Eclipse: https://github.com/gracebear/AppletPlayground
There are also links to other open source and free-n-easy to use components.
Normally I use Jcop, which is the a plugin of eclipse. You can install the eclipse first . And then add the JCOP plugin into it.
To starting developing an applet for Java Card :
1. Download and install Java JDK. (on Oracle website), and setup your JAVA_HOME
2. Download eclipse for Java developer in eclipse.org (newest version is Neon). Extract to use it, it's portable app.
3. Download Java Card JCDK 3.0.5 (newest) and install.
4. Install the JCDK plugin on Eclipse
Note: You can following the getting started document in JCDK 3.0.5 how to setup environment and running or compiling the applet.
I am using Blackberry eclipse java plugin 1.5
I am not getting BB development environment.
Preprocessor directives supported by the RIM compiler
and Using preprocessor directives in BlackBerry JDE plugin for eclipse?
I used those links but not working..
Plaese help
My recommendation is to use this latest download of Eclipse & the plugin.
BlackBerry tools are not very good, so I find it best to use a dedicated Eclipse, only for BB dev. I have found that this download is working well for me.
Install this version - I think it will fix all your problems. If not, reply and I'll see if I can help further.
I'm trying to run an existing GWT project in Eclipse as a Web Application. This runs on other people's PCs, and I used a setup document common to us all to install Eclipse and GWT. I consistently got the error:
Google Error
Not Found
The requested URL /missing-plugin/ was not found on this server.
So far, I have verified that the GWT SDK is installed, and that the Google Plugin for Eclipse 3.5 is installed. I uninstalled just the Google Plugin, and then everything Google, and reinstalled, with no luck. at this point, after poking around a lot, all the Google stuff is installed, but the "Run as Web Application" option is completely gone. I've googled this, but no luck so far.
Any ideas?
As of GWT 2 (or there about), a new browser plugin is required for developer mode. You can get it here: http://gwt.google.com/samples/MissingPlugin/MissingPlugin.html
