[Solved] How to deploy spring boot project (Java deployment failed)

[sepiqon]

Welcome! I'm having problem with deploying my file .war.

Username: sepiqon

Domain: sepiqon.heliohost.org

My war file: sepiqon_server.war

Server: johnny.heliohost.org

I did read this post: 

https://www.helionet.org/index/topic/28053-solved-deploy-war-app-request/page-3?hl=maven&do=findComment&comment=128900

But it doesn't working for me...

 

I get error "Java deployment failed with errors. For further information please contact support.", previously the code 404 on sepiqon.heliohost.org/sepiqon_service

This app works on local tomcat.

Krydos should be able to get you the Tomcat log for the deployment failure.

[sepiqon]

Deployed. http://sepiqon.heliohost.org/sepiqon_server2/

error 404 - not found 

[wolstech]

Give it a little while for Apache to restart.

 

Also, I removed your HTTPS redirect. HTTPS is incompatible with Tomcat by default. Krydos can make a special change to force it to respond to HTTPS if you really want to, but it comes at the expense of performance and the ability to accept plain HTTP connections (you can only pick one or the other, both would double the amount of load your site causes). For now, lets just get it working first...

[sepiqon]

i would like https, but i also want to be able to connect to MySql

[wolstech]

That app is now working on plain HTTP: http://sepiqon.heliohost.org/sepiqon_server2/

 

HTTPS doesn't affect mysql at all. It's just that your Java app won't be able to accept a plain HTTP connection (not terribly important unless you have a need for programs that can't handle HTTPS to connect, or perhaps you have users on older PCs that are still running XP). HTTPS can be much slower when server load is up though, which isn't uncommon on Johnny.

 

Krydos would need to configure the HTTPS for you.

[Krydos]

Your java deployment has been moved to ssl https://sepiqon.heliohost.org/sepiqon_server2/ Keep in mind if you change the filename the ssl will no longer work.

[sepiqon]

I understand, thank you for your help. The 404 error is still there. I have to wait?

[sepiqon]

Sorry, but everything works thank you, I have another question, Can I update my war file, I'm worried about HTTPS

[Krydos]

You can update the .war file, and deploy a new one as long as it has the same filename as the previous deployment.

[sepiqon]

Hello, I often have "Java deployment failed with errors.".

Can I see what this error is?

...without error : max_user_connections

I'm sorry for frequent deploy

Name war: sepiqon_server2.war

Your .war failed to deploy because tomcat had crashed. I restarted tomcat and your .war deployed without errors. Thanks for letting us know that tomcat on Johnny was having issues.

[sepiqon]

I changed it: 

        registry.addEndpoint("/onlineusers").setAllowedOrigins("*")

        .withSockJS();

to:

registry.addEndpoint("/onlineusers").setAllowedOrigins("*");

and  Java deployment failed

 

When using SockJS, I have the error: WebSocket connection to "ws://sepiqon.heliohost.org/sepiqon_server2SockJS/onlineusers/.../.../websocket" failed: Error during WebSocket handshake: Unexpected response code: 400, (and adres: "wss://sepiqon.heliohost.org/sepiqon_server2/onlineusers/.../.../websocket")

 

without SockJS, I tried to connect to the url: wss://sepiqon.heliohost.org/sepiqon_server2/onlineusers

but I don't know if the url  works: wss://sepiqon.heliohost.org/onlineusers

(https://www.helionet.org/index/topic/37604-java-websocket-connection-failure/?p=168706)

Please help

 

with SockJS I cannot connect to the last two addresses,

Please help

 

file .war deployed: sepiqon_server2SockJS.war

file without SockJS: sepiqon_server2.war

 

Please help!
