Good day everyone!
I am a graduating student doing Google App Engine-Java Web Application.
My problem is I need to compile/build it so it will run upon click. I've been trying exporting it to a jar file however it outputs no main class.... problem.
I've been looking for other method but internet fails me or maybe i'm not pointing on the right track.
Here's my output whenever I'm using the command line:
its working fine when i'm using eclipse.
Any leads? Sorry if my question is quite silly.
Thanks in advance :))
Firstly you should definitely consider updating your GAE SDK as it seems the defaultZoneTL field was removed from JDK 1.6 U31. Updating the GAE SDK should avoid that problem.
If you can't do that then check http://code.google.com/p/googleappengine/issues/detail?id=6928 and try to implement one of the workarounds suggested. (Essentially launching with -Dappengine.user.timezone.impl=UTC OR -Dappengine.user.timezone=UTC)

I'm getting
Error: Unable to access jarfile C:\Users\stepa\workspace\sse-chat-java\\activator-launch-1.1.0.jar
when running Markus Jura's Play Framework simple chat application on windows 10 system.
On a Ubuntu machine Markus Jura's Play Framework simple chat application works without any problems.
This is what I tried so far:
reinstalling Typesafe Activator to the currently newest version (2.4.3 - same as on Ubuntu machine)
searching for activator-launch-1.1.0.jar (not present on any of the machines)
searching for someone with same problem
I'm running out of ideas. I appreciate any suggestions.
There are 2 places where you may try to change version. See image below (but please also check another file).
I'm not sure it will fully fix your issue, but it worth a try.
Since I remember I've always been able to create a Java Application in Netbeans doing File->New Project->Java->Java Application. Today I turned on my computer and the Java field "disappeared". The only thing I did in the past days is to begin working with Java FX. I checked the Plugins and everything seems fine.
I did some quick research but couldn't find anything similar.
Thanks for the help in advance
I've been working on this project for months, and when I started out I knew nothing about android dev, gradle or signatures. Since Android studio was also quite new when I started in June, and updates often brought errors in the gradle, the code is a bit messy.
Now, I've been trying to get the new support library imported into my project - without success. Re-importing the project seems to fix this nice and easy, but this means I have to replace the old project(package anomaly). My question is, since this app is already deployed, will I loose the old signature and with it the possibility to update the app on Google Play store?
Hope to hear from ye! Thanks.
[EDIT]
Yep, worked like a charm :) Thank you Samuel!
If I am answering the question I think you are asking, can you change the package name and still upload the application as "updates" to one that is already in the market the answer is no.
Once an application is uploaded to the market, pretty much everything can change except the key and the package.
As long as you still use the same signature and key then you should be able to compile with different things and still upgrade successfully. I highly suggest compiling what you have now and trying to upgrade it in the app market and that will very quickly determine whether or not it is possible. If you do this post back on this post if it worked or not for everyone else to see
I've just started to mess around with red5 , I can't say it was easy to get it run at the first place, but after a day on google I finally succeed.
The first thing I had to face is the poor documentation of this server. I couldn't find any good tutorials about making apps (I would pay for a good one, but still nothing) for it, but it doesn't matter since it's free.
I found this : Adobe TV . It's the best starting point I could find so far. The only thing is that I can't set up the same working enviroment as the guy has in the video. I understand it is eclipse (i have that) , and i know he is using flex plugin, but how do I get eclipse to debug mxml files as he does? (around 3.20 in the video) . I downloaded the flex plugin, but after I install it, eclipse stays exactly the same as before.
PLease note I am new to eclipse (and JAVA and flash -huhh... :D - ).
I am running Windows 7 Ultimate 32bit.
Any help would be greatly appreciated.
There is one more IDE called FDT for flex app development. They are using eclipse. Worthy to try this IDE http://fdt.powerflasher.com/ this is available linux too. This is does not support red5 by native. But you can just simply create as java project.
I prefere the Flex Development to do with flashdevelop: http://www.flashdevelop.org/
it is a very nice openen source code editor. Configuration is really easy and takes just 1 Minute. The only thing to do is to configure the path of the flex sdk. Debugging is nice and i love the code completition feature.
I've been wanting to try using AppEngine in conjuction with my android app. My main problem is i can't seem to get the installation to work corrently, or at least that's what i'm assuming is going wrong.
I installed appengine and all the required plugins with eclipse from the instructions here http://code.google.com/eclipse/docs/appeng_android_install_setup.html But even when i just try run the test project it crashes without error (or at least nothing shows on LogCat or console) when i try and get it to send a message to the webserver and crashes about a minute after just adding a google account on the emulator. Is there any way to fix this that anyone knows of? Or perhaps another tutorial to install, it's getting to the point i'm not really sure where to go from here.
