Anvil-open-server install offline

Anvil Q&A
1

I am trying to deploy Anvil app server in my offline industry computer.

**What I’ve tried and what’s not working: I’ve installed Amazon Coretto ( Java ) and installed anvil-app-server but it couldn’t download app server JAR **

Where can I download App Server JAR and install it on my offline computer ?

Do you mean to say your computer has no access to the internet?

Yeah in my company network I want to deploy an app with anvil open server . But it needs the JAR file

Hello @coolshiba998.

You can follow the installation instructions at https://github.com/anvil-works/anvil-runtime on another, internet-connected pc and then copy the jar file from there.

I just now created a virtual environment on my Windows pc, and within the directory where that environment’s saved, the path to the JAR is

Lib\site-packages\anvil_app_server\

but the path might differ for other operating systems. The filename of the current runtime is

anvil-app-server.20241127-184105.jar

Because the Anvil runtime uses a lot of other Python packages, and because those might conflict with versions that are already installed on your internal/isolated server, I recommend that you

  1. Create a virtual environment on your company server for the Anvil runtime
  2. Perform your initial install on a web-connected system that has the same OS as your company server and the same version of Python as is installed in your virtual environment.
  3. Copy the entire contents of the Lib\site-packages directory (not just the JAR file) from the web-connected system to your isolated server.

Hope this helps!

Thank you for the prompt reply @tomherden .

I just did the same as per your instructions .

but it always shows

Session time out .Please refresh the page .

Upon refreshing it shows the same message -
Session TimeOut. Please refresh the page

What to do when this shows up ?

Note - I just created and deployed prebuilt Todo List App as per the example in Anvil docs.

I have only a little experience with the Anvil Runtime server, so other forum members (or Anvil staff) may be better able to assist you – but in the meanwhile, I’ll try to help.

You reported two different error messages, each of which resembles a message that the Anvil Runtime server might generate:
"Your session has timed out. Please refresh the page to continue.”

If that is the message that you’re actually seeing, then the good news is that you have successfully installed and are accessing the runtime server from your browser. Let’s get some more information to help troubleshoot:

  1. When you say “it always shows”, do you mean that accessing the MyTodoList app immediately and only results in that error – or is the issue that, after the app works for a while, that error appears?

  2. What URL are you using to access the app?

  3. Is the browser that you’re using running on the server, or on another computer on your company’s internal network?

Hey @tomherden , Thank you for the reply

Yes its this message that is shown when I deploy the app.

"Your session has timed out. Please refresh the page to continue.”

I would like to answer the questions that you have posted -

  1. While accessing the MyTodoList app it immediately shows this and only results in this error and The app doesn’t work even for a moment.

  2. My localhost URL

  3. Yes the browser is running on the server

This looks to me like a problem with the MyTodoList app – although it seems unlikely that would have resulted from using the

create-anvil-app todo-list MyTodoList

command that’s shown in the instructions in the anvil runtime repository README.

I’ve created an ultra-simple app that you can use to test your server installation:

https://github.com/therden/simplest_anvil_app

It just serves a couple of routes. If you save it to a subdirectory of your anvil_runtime directory and it works, then my hypothesis is correct. If not, then I’m afraid you’ll need to rely on other forum users or Anvil staff for assistance.

In the command prompt it shows like this

anvil-app-server_msg
anvil-app-server_msg1088×526 21.1 KB

And then it shows in browser this -
anvil-app-server_msg2

and I saw that It needs to connect atleast once to Internet then only the Session timeout message disappears

Please try the ‘Simplest App’ that I linked to on the 29th. If it works, then I’d take it as confirmation that

  1. your Anvil runtime server installation was successful, but
  2. the difficulty you’re experiencing is due to some part of the todolist app requiring an internet connection.

If it doesn’t work, then maybe there is a problem with the runtime installation. (But since you aren’t getting any errors on startup, I’m increasingly skeptical that that’s the case.)

@coolshiba998 please dm me or send me an email to tobias@carlbomsdata.se
I think i have something for you to test.

I have packaged anvil-app-server in to one single executable (for windows) including the jar file.
