Error when trying to use airline-web

[foxyfred]

I very much may be blind, but when i try to connect to the localhost:9000 I get this error in the web console:

[drvntechnologies]

Is this when initializing in the console or after it's up and running? Are you able to connect in the web browser? Asking because I have some similar errors right now

[foxyfred]

everything is initialized and the mainsim console says its simulating, but when I run the web side of the system it gives that error when trying to connect to it in the browser, in which the browser screen shows the same error.

[foxyfred]

I'm unsure what caused the error, but I wiped the old install and reinstalled the whole system, including the database and the error disappeared.

@patsonluk I have this same issue when installing from an unzipped directory on MacOS. I'm using xampp on localhost:3306 for SQL and the airline_v2 as db name. It shouldn't be empty on install right? Java is installed. How can I host this solution externally? I feel the readme could go into more detail.

Inside airline-data folder:

[patsonluk]

I have only tried it on linux (our prod) and windows env (my dev). not sure if there are any gotchas for mac 😓

From the stack trace it seems to be java.lang.UnsupportedOperationException: The Security Manager is deprecated and will be removed in a future release issue?

We are using a pretty old sbt/scala version, perhaps u r running a very new java version which triggers that issue? Can u try java 11?

[patsonluk]

I also think it's related to this? https://stackoverflow.com/questions/76151072/error-during-sbt-launcher-java-lang-unsupportedoperationexception-the-security

[kimbon30]

Have you got a hosting solution that you use @patsonluk ?? Sorry, I don't know how else to contact you.

Purchased a VPS, on debian 12, mysql set up as 5.7 with defaults and airline_v2 as db name.

I was using digital ocean, and now using google cloud. you will need a host that u have full control of all the installed packages (such as java). it's a bit concerning that it's placed under /www/wwwroot/admin which seems to be website hosting for me. The airline-club requires more than just website hosting, it needs the part that runs the simulation.

It still look like a java problem to me, java.net.http is a very basic package for java and it should present in all versions. The problem indicate that your java compiler somehow cannot lookup that class. This indicate classpath looking issue from sbt.

Your VPS seems to have java installed, but probably in some rather different way such that classpath lookup works differently.

[kimbon30]

I have uploaded the files to an FTP with a free web panel on a Debian 12 VPS. I assume this does not deploy as a website but as an app? I had a scan through the source code, and I understand most of the syntax, just not how the app is structured / dependencies etc. I'm afraid that google cloud will become too costly for a deploy that will be private.

It would help if you could share your workflow? I would even pay.

[patsonluk]

u likely need full shell access instead of FTPing files over. The workflow is as in the README https://github.com/patsonluk/airline?tab=readme-ov-file#setup
