I have just deployed Eclipse Neon in a Windows 7 environment (coming from many years of using Netbeans) and the Google (java) App Engine environment (as Google instructs and all works).
Using the standard gae 'hello world' example, when I make a change to the text on the sample 'Hello App Engine Standard' .jsp, for example changing that text to 'Hello hello', I have two issues:
In Eclipse I have to save and then hit F5 to refresh. Is there any way that Eclipse can auto-refresh on save like Netbeans does?
After saving and hitting F5 I then need to reload my browser 4-5 times before the trivial change shows up. Netbeans does it instantly. Does anyone have any idea where I start looking as Eclipse is totally new to me or is this just the way Eclipse works?
Thanks
If you are using the Cloud Tools for Eclipse plugin, you can set the publishing delay on the server as follows:
Double click on the local devappserver in the Servers view:
In the editor that opens up set the publishing interval to 0 seconds:
I had previously done some work in java GAE. Eclipse was pretty terrible frankly ended up switching to intellij. Shortly after I ended up switching to python for it. I use pycharm from the same company, you need the pro edition sadly, also here is a great lib for it supposedly it runs fairly similarly in terms of speed in GAE compared to java. Also endpoints will generate client code for you with little work.

I'm coming from NetBeans and evaluating others and more flexible IDEs supporting more languages (i.e. Python) than just php and related.
I kept an eye on Eclipse that seems to be the best choice; at the time I was not able to find an easy solution to keep the original project on my machine and automatically send / syncronize the files on the remove server via sftp.
All solutions seems to be outdated or stupid (like mounting a smb partition or manually send the file via an ftp client!
I'm not going to believe that an IDE like Eclipse doesn't have a smart solution of what I consider a basic feature of an IDE, so I think I missed something... On Eclipse forums I've seen the same question asked lots of time but without any answer!
Some suggestions about is strongly apreciated otherwise I think the only solution is stick on one IDE each language I use that seem to be incredible on 2018.
I'm developing on MacOS and the most interesting solution (kDevelop) fails on building with MacPorts.
Thank you very much.
RSE is a very poor solution, as you noted it's a one-shot sync and is useless if you want to develop locally and only deploy occasionally. For many years I used the Aptana Studio suite of plugins which included excellent upload/sync tools for individual files or whole projects, let you diff everything against a remote file structure over SFTP when you wanted and exclude whatever you wanted.
Unfortunately, Aptana is no longer supported and causes some major problems in Eclipse Neon and later. Specifically, its editors are completely broken, and they override the native Eclipse editors, opening new windows that are blank with no title. However, it is still by far the best solution for casual SFTP deployment...there is literally nothing else even close. With some work it is possible to install Aptana and get use of its publishing tools while preventing it from destroying the rest of your workspace.
Install Aptana from the marketplace.
Go to Window > Preferences > Install/Update, then click "Uninstall or update".
Uninstall everything to do with Aptana except for Aptana Studio 3 Core and the Aptana SecureFTP Library inside that.
This gets rid of most, but not all of Aptana's editors, and the worst one is the HTML editor which creates a second HTML content type in Eclipse that cannot be removed and causes all kinds of chaos. But there is a workaround.
Exit Eclipse. Go into the eclipse/plugins/ directory and remove all plugins beginning with com.aptana.editor.* EXCEPT FOR THE FOLLOWING which seem to be required:
com.aptana.editor.common.override_1.0.0.1351531287.jar
com.aptana.editor.common_3.0.3.1400201987.jar
com.aptana.editor.diff_3.0.0.1365788962.jar
com.aptana.editor.dtd_3.0.0.1354746625.jar
com.aptana.editor.epl_3.0.0.1398883419.jar
com.aptana.editor.erb_3.0.3.1380237252.jar
com.aptana.editor.findbar_3.0.0.jar
com.aptana.editor.idl_3.0.0.1365788962.jar
com.aptana.editor.text_3.0.0.1339173764.jar
Go back into Eclipse. Right-clicking a project folder should now expose a 'Publish' option that lets you run Aptana's deployment wizard and sync to a remote filesystem over SFTP.
Hope this helps...took me hours of trial and error, but finally everything works. For the record I am using Neon, not Oxygen, so I can't say definitively whether it will work in later versions.
Perhaps I pop this question to early as Openshift v3 is still in preview, nevertheless there might be a solution to my problem that I don't see :).
I'm taking my first steps in building a java Play framework app and chose Openshift as my hosting platform. I just was able to get my app + mysql db working on Openshift v2 as they released v3 preview and got notice v2 will eventually disappear.
In the new images/templates there is still no Java Play version showing and no 'do it yourself cartridge' way.
Any hints or 'tutorial' links are much appreciated :).
Thanks and kind regards!

You have two options here.
SBT Native Packager
First option would be using the SBT Native Packager SBT builder to create your Docker images (either manually or using something like Jenkins). Out of the box you should be able to run sbt docker:publishLocal and get a local docker image which you can then push to a Docker repo. You can then launch it in openshift with oc new-app <docker repo>/<docker image>:<image version>.
Down side to this is that you aren't really taking advantage of OpenShift fully since your images are being built elsewhere. But it might fit well with your current development flow.
Upside is that your docker images will be quite small. SBT does a good job of packaging up all the dependencies.
Source to Image
Second option would be to create your own source to image builder that knows how to build sbt/play projects. This is the path my team has taken. You can take a look at our sbt builder for reference but its still beta quality at best.
Downside to this process is that all your source is included in the image so its a big larger. Also no one supports this builder so if you have bugs you are on your own.
Upside is that OpenShift will build your images and you will see your build status inside the OpenShift web console.
Notes
With OpenShift Origin 1.3.0 you will also get access to the Jenkins pipeline. This can make either of the two above scenarios easier. You end up with a cool web interface that looks like this:
Hopefully RedHat will support sbt natively at some point but for now one of these two flows should work for you.
For everyone looking for an answer to my own question, here is how I got a Play app running on Openshift (own installation).
First of all, a big thank you #PatrickTescher. His answer pointed me in the right direction.
I did not yet succeed in getting a docker build by activator to work in Openshift (guessing it has to do with running under root), but I have gotten to the point where I have a Source to Image build running on my own Openshift Cluster. This approach is not yet possible with the online developer preview of Openshift. By all the reading I have done so far, I agree with Patrick to say this is the best approach.
By diving into the following links, you should get up and running:
Installing docker on a Windows vm: https://docs.docker.com/toolbox/overview/
Installing your own Openshift Cluster: https://github.com/openshift/origin/blob/master/docs/cluster_up_down.md#windows-with-docker-toolbox (in addition: https://github.com/openshift/origin/issues/11277)
Get a s2i image up and running: https://github.com/redhat-cop/containers-quickstarts/tree/master/s2i-play
In the last link you can change registry.access.redhat.com/rhel7.2 by registry.centos.org/centos/centos:latest (rhel needs certification, centos is the free community equivalent)
I am new to the flex development world. I have an environment where Flex is the client and Java is on the server. The IDE's I am using for each are Adobe FlashBuilder 4.5 and Eclipse.
The problem is that I am stuck at debugging across the two languages at the same time. I begin debugging in Flex and at the same time I set a couple of breakpoints in Eclipse. However, when time comes for the program to shift to the server side, it doesn't quite enter debug mode in my Eclipse IDE.
Perhaps I am missing out on linking the two, but from what I have read is that this is automatic. Looking forward to your answers :)
I have a problem, with multiple possible solutions.
I'm doing a Computer Sience study and I'm working as an intern at the moment. My assignment is to make a business application for Android & iOS. I've been working for 2 years with Visual studio 2010 now, Xcode is rather simular so that's no biggy, Eclipse on the other hand is not as what I'm used to, I'm not saying it's bad. I have enjoyed Eclipse so far but now i'm constantly using Xcode and Eclipse
Now hold on there before you answer! I know there is an autocomplete in Eclipse but it will only pop after you push Ctrl + Space or after one of the maximum of four Auto activition triggers is, well, triggered.
So my question is:
Is there any tool that does trigger auto complete after every keystroke or something?
I tried looking at making my own Eclipse plugin but it was way to hard with zero knowlegde about the Eclipse API, although tutorials considering the Auto Complete features are welcome! (they should cover classes like ContentAssistCommandAdapter)
Thanks in advance!
The delay between keystroke and pop-up is configurable. So, as an alternative to a plug-in, you can adjust the autocomplete settings to pop-up after a shorter period of time, such as 1/10th of a second.
Eclipse preferences ->
Java ->
Editor ->
Content Assist ->
Enable Auto Activation
Auto activation delay (ms)
(showing Mac OX 10.6, running Eclipse "Indigo" release, but the option has been around forever):
I've been stumped for a while trying to figure out why my GWT demo app isn't working in hosted mode so I went back and downloaded the Google Web Toolkit again, unzipped it and simply went to the samples directory and ran "ant hosted". The hosted browser launches and only shows the static html content but none of the dynamically generated js widgets, etc. However when I click "Compile/Browse" the examples launch correctly in Firefox. What could be wrong with my setup/environment?
I followed the link you provided to download gwt. Extracted and ran "ant hosted" under samples/Hello, samples/DynaTable, and samples/Showcase and they all worked successfully. I'm also running Windows XP and java 1.6.0_11.
I think that running "ant hosted" starts an embedded Jetty server that listens on port 8888. Hosted Mode Browser makes requests to that embedded server, for example: http://localhost:8888/Showcase.html.
Also, when you click "Compile/Browse", it opens your default Browser (in my case it's firefox) and it tries to make a request to the same embedded jetty server that the hosted mode browser uses.
So, if it works in your browser, then the browser is connecting to the embedded jetty server. It's very strange that hosted mode doesn't work properly but you're able to view in a browser.
I believe the difference here is that hosted mode runs pure java (some sort of javascript emulator, I'm not sure I understand 100%), while the browser is running javascript.
So, I suggest troubleshooting the jvm that is started when "ant hosted" is run. Maybe the jvm is running out of memory or something when you load it up in hosted mode browser? Maybe you can pass some jvm args to the ant script to fix the problem?
Sorry I can't be more specific, that's a strange one!
#Chris: I suspect this question may have something to do with your earlier question if it is on the same computer that you were using. The solution may be to clear your IE cache because it tends to cache the 'script' tag contents and when it got messed up earlier while you were importing other stuff, it may still be sitting around in IE. Found the potential answer at this link.
I created a new workspace, re-imported everything and used GWT 1.6.x instead (because Ext GWT 2.X, which I need for this project requires GWT 1.6.x). This did the trick... everything works ok now.
The main difference I can think of is that in the Compile/Browser you are opening the html host page like a regular file, while in the hosted mode (even in a client sample) it has to be provided by the http server via localhost:8080. Check if the server is beeing started.
