B4J Question [BANanoServer] Not Able To Serve up a BVAD3 Site

[B4XDev]

I've got an nginx reverse proxy on a Windows box serving up some B4J and BANano servers.

@aeric 's API site works fine. It connects to MySQL, as well. Seemingly no obvious issues...

I can't get @alwaysbusy 's BANanoServer to serve up @Mashiane 's BVAD3 server.

Here's what I get:

So... it almost comes up! Something is coming through...

But why doesn't it finish?

I'm guessing it has something to do with the websocket functionality. Maybe something is blocking the front-end's ability to contact the back-end, or vice versa?

I'm stuck here and have been for many days... so if anybody has any ideas, please let me know!

 

[B4XDev]

Additional information: I'm actually able to run the B4J server with the same (or similar-enough) nginx config file, as you can see here: B4XDev.com.

The websockets are actually working there, so I'm not sure if websockets are really the issue. They still could be, depending on what BANanoServer is doing... maybe... I have no idea.

Note hat BANanoServer is just a wrap around the normal B4J jServer with some convenient methods and classes prepared. As it is a .b4xlib, you can simply unzip it and look into the source code.

Things you can try to identify the problem:
1. open it in chrome, press F12 and look if the browsers console does show errors (missing files?)
2. are there any errors in the B4J log?
3. Do your class names have the proper BROWSER or SERVER prefixes?
4. look into the Kitchen Sink example Mashiane has mad how things are done: https://github.com/Mashiane/BANanoVuetifyAD3/blob/main/BVAD3Server.zip I believe this is a BANanoServer + BDAV3

Thanks Alain, surely checking those logs will provide us green lights in terms of the underlying issues especially the web logs in this particular case.

1. open it in chrome, press F12 and look if the browsers console does show errors (missing files?)

The only error in Brave browser console is: "Uncaught vform1: Error - the recordsource name has not been specified"

That has to be where it's breaking, but I'm not sure what it means.

2. are there any errors in the B4J log?

Not that I can tell:

3. Do your class names have the proper BROWSER or SERVER prefixes?

I'm actually using the Kitchen Sink as a test case for a web app project we're trying to get done.

Looks like a BVAD3 issue, so I'll continue debugging with @Mashiane .

Thanks for the help!

Step 3:

• Download and run the BANanoVuetifyAD3 library source code. This will compile the b4xlib from the source code source code.

Done.

• Also ensure that the External Libraries are copied to your B4J external libraries

Confirmed.

• Download the BANanoVuetifyAD3 BANanoServer Kitchen Sink, we will use this to deploy our tests.

Got it.

• This deployment test should work for all other BANanoVuetifyAD3 BANanoServer projects

Then update the config.properties file like this. You access this via the Files Tab of your b4j project.

Host=http://localhost
Port=55056
PortSSL=0

Save and run the application, DO A HARD REFRESH of your browser.

Done.

Here's the current error:

 

[Mashiane]

Oops, sorry, I forgot, on that updated kitchen sink project we have referred Alains JKSStore, please also execute Step 1.

 

[B4XDev]

How do I test it on a non-secure connection? I'm on a local Windows PC with no way to secure it (no domain pointing to it).

 

[Mashiane]

Post 6 above is on a non-secure connection.

Thing is the posted source code for the Kitchen Sink also speaks to secure-connections, you just need to update the config.properties files for a non-secure connection, that's all.

It seems the websocket is attempting a secure connection.

If I modify BROWSERIndex, line 143, to read:

ws.Initialize("ws://" & BANano.Location.GetHost & "/ws/" & BANano.StaticFolder & "/index")

instead of

ws.Initialize("wss://" & BANano.Location.GetHost & "/ws/" & BANano.StaticFolder & "/index")

I still get the WebSocket failure message as above.

 

[Mashiane]

Save and run the application, DO A HARD REFRESH of your browser.

Do you?

 

[B4XDev]

Do you?

Yes. And in an incognito browser.

And in both Brave and Edge browsers.

 

[Mashiane]

I wonder why is your browser not picking up the new compiled version, did you try clearing the browser cache manually? It should be working by now.

 

[Mashiane]

I've just installed Brave and managed to run the BANanoServer Kitchen Sink. Please recheck the web console of what could be the cause.

 

[B4XDev]

 

[aeric]

Shouldn’t the url be wss://localhost:55056/ws/ ...

 

[Mashiane]

Lets try it once more...

Your browser is still using a cached version of BVAD3Server Kitchen Sink, unless...

• Please, just recheck this line on BrowserIndex

ws.Initialize("ws://" & BANano.Location.GetHost & "/ws/" & BANano.StaticFolder & "/index")

• Open the windows task manager, kill all instances of java.exe or if you can find the one instance the bvad3server is running on, kill it.
• In the BVAD3 Project, goto tools and click clean project.
• Delete the compiled Objects folder on the BVAD3 project.
• Run the BVAD3Server project again (in release mode)
• When the browser opens, do a hard refresh of the browser.

 

[B4XDev]

Shouldn’t the url be wss://localhost:55056/ws/ ...

Maybe. I don't know.

But @Mashiane can use it just fine as is. So it must not be an issue... at least it's not for him!

 

[Mashiane]

Shouldn’t the url be wss://localhost:55056/ws/ ...

Nope, that is applicable to this version
