When I try to run my (local) play application via the play2 plugin from intellij I get:

If however, I run it via sbt run, everything works like a charm.
1) Why is that?
2) How can I fix this? (Running on Linux 4.11 here - I understand that the port is only allowed "sudoers", but then I wonder why the sbt-way works)
3) Any other way to run play in "debug mode"? I would like to set some break points and analyze the flow.
I ran into similiar issues before. Deploying to port requires permissions, if you want to strt the service on local, you can change the port to 9000, if you don'5 want this issue to occur. Then, when you deploy on production, you can change it to 80 and follow this guide :
https://www.playframework.com/documentation/2.5.x/Deploying
If you have changed build.sbt to listen on port 80, remove that line. IntelliJ still thinks app wants to run on 80
And also:
If you have changed application.conf, make sure port is not set to 80.

I checked the port BOOTSTRAP_ADDRESS in the file serverindex.xml
<specialEndpoints xmi:id="NamedEndPoint_1183122129640" endPointName="BOOTSTRAP_ADDRESS">
<endPoint xmi:id="EndPoint_1183122129640" host="F120000.cargas02.sir" port="2809"/>
</specialEndpoints>
The output command netstat -ano is
TCP 0.0.0.0:2809 0.0.0.0:0 LISTENING 4072
How can I fix this error?
Usually an ORB Listener Thread creation failure occurs because either:
Another process is already listening on the port in question (in this case 2809).
The ephemeral port range has been expanded on the OS such that the WebSphere server port ranges (2800 - ~10000) are now included in that range, increasing the possibility of a WAS server port number being assigned to another process as an ephemeral port.
For scenario #1: use netstat -ano or lsof -i :<port#> commands and search for the port to find the process using the port. If a conflicting process is found, change the config/port ussage of that process. Or edit the WebSphere serverindex.xml file in dmgr-profile-root/config/cells/cellName/nodes/nodename (make sure to take a backup beforehand). Change the 2809 port to another port not in use. Save and sync the changes.
For scenario #2: Check the ephemeral port range on the server box (internet search based on the OS will give specific instructions for this). Make sure the low end of the port range is sufficiently greater than the highest WebSphere server ports found in the serverindex.xml file.
Finally, it's also possible the WebSphere server did not properly shutdown and close all ports from its previous run. An OS reboot may be needed to release the port(s).
I'm using ubuntu 16 and I downloaded and installed the last version of android-studio (file android-studio-ide-181.5056338-linux.zip).
I'm running android-studio behind a corporate proxy. I unzipped the file and I launched the studio.sh and I configured the proxy by following these links https://developer.android.com/studio/intro/studio-config#proxy and link https://www.jetbrains.com/help/idea/2018.1/settings-http-proxy.html
Note I configured also my proxy authentication (both username and password) as showed in this image:
When I check the connection if I use some unsecure URLs (e.g. http://www.google.it) all works pretty good; the check is OK. If I use secure URLs (e.g. https://www.google.it) I get a 407 error (authentication required)
as showed in this image
Then I saved the settings and closed the IDE. Note I created no project yet... I just installed the IDE.
Now every time I start the IDE in the idea.log I see the following error:

So it seems that my proxy settings are not used by the update phase. Note i tried also to use unsecure connections but the error remains.
Ho can I solve this issue?
Thank you
Angelo
Try this.
Change your Proxy settings like this.
And test your connection again.

Selenium 2.53.1
I installed Xvfb then I did something like this
Xvfb :77 -ac
and
export DISPLAY=:77
then I checked if firefox works on linux ($firefox) -> launched without error, and stay running until I kill it with Control-C
Now I try to start my selenium tests using Jenkins. I indicated my DISPLAY but when I run tests I get:

Can anyone tell me what happens here? How to solve this problem?
It works fine on windows - I mean ff 43 and selenium 2.53.1
Check the parameters of the X virtual frame buffer, when you start it. I think the issue is here. For me it worked, I did it step by step following headless execution of selenium tests in Jenkins blog post.
I have followed the installation instructions as shown here

by default the server runs at the port 9898 as shown on the above output,I have tried using netstat and lsof to find what service is using that port but no one does!
also tried to change the port from the configuration but also no luck!
Has anyone had the same problem? if yes have he/she solved it? and how
also is there any linux command that I can query the port and tell me who is using that service?
So it terns out that the server runs after all but for some reason it complains about the bind exception.
The correct way to look for the service given a port is either the one on the comment above or using fuser <protocol> <port>.
