Hi

Please may I move my account from Johnny to Tommy

Account name: slimsim

Transaction ID: 16331886NN6509928

Many thanks

I'm trying to let my users upload files in a RESTful spring boot web service.

I followed this tutorial 

https://www.callicoder.com/spring-boot-file-upload-download-rest-api-example/ 

where the uploaded files will be stored in the local file system.

it says to configure what folder the files should be stored in with

file.upload-dir=/Users/callicoder/uploads

But when I package the war-file I must have that folder on my computer, which leads me to believe that it will not work when I deploy it to the server. And sure enough, when I deploy the war-file, I get "deploy failed with error", even though that file is on my "File Manager".

Does any one have any tips on how to achieve this? 

or is this not allowed on HelioHost, should I save the files in the DB instead?

Do you have any good tutorials you can point me to?

Thanks in advance!

Thanks for the help!
 

When I try with the following information in pgAdmin4:

Name: slimsim_ava_db_dev_1

Host name / address: johnny.heliohost.org

Port: 5432

Maintenance database: slimsim_ava_db_dev_1

Username: slimsim_db_user

I get 

Unable to connect to server:

FATAL: no pg_hba.conf entry for host "92.34.255.150", user "slimsim_db_user", database "slimsim_ava_db_dev_1", SSL off

If I try the same information but use port 3306 i get:

Unable to connect to server:
received invalid response to SSL negotiation: J

Do you know what the problem is?
What port should I use?

Thanks so much for the help!

Hi,

Please can you assist me with enabling remote access on my PostgreSql database?

Name: slimsim_ava_db_dev_1

Host name / address: johnny.heliohost.org

Port: 5432

Maintenance database: postgresql

Username: slimsim_db_user

This is error i get when trying to connect:

Unable to connect to server:

FATAL: no pg_hba.conf entry for host "92.34.255.150", user "slimsim_db_user", database "postgresql", SSL off

Thanks!

Hi

Is it possible to run more than one java application on my account?

When I uploaded two different war-files and deployed them, only the last war-file was running.

I would very much like to host a couple of apps on this server!

Thanks for the help!

Hi

I'm trying to send data from my Java Spring Boot backend to my frontend using webSockets StompJS.

But I'm gettign the followign error in the browser console:

WebSocket connection to 
'ws://slimsim.heliohost.org/slimsim_ava/gs-guide-websocket/015/sxvos2r2/websocket' failed: 
Error during WebSocket handshake: 
Unexpected response code: 400

Is it possible to get the server-logs? This request was made at about 2020-10-21 14:16:45.

My info:

• Username: slimsim
• WAR-file: slimsim_ava.war
• Path: /home/slimsim/
• Server: johnny

I have read a lot on this forum, but I can't seem to find any one who have used Stomp. It works on my locahost as well as on my last web hosting server. Does anybody have any tips?

My JavaScript code is the following:

    connect = function() {
        const funk = "connect";
        console.log("\n\n\n\n" + funk + ":\n");
        const socketPath = thymeLeaf.contextPath + 'gs-guide-websocket';

        console.log( "*** " + funk + ": socketPath", socketPath );
        var socket = new SockJS( socketPath );
        console.log( "*** " + funk + ": socket", socket );
        stompClient = Stomp.over(socket);
        console.log( "*** " + funk + ": stompClient", stompClient );
        stompClient.connect({}, function (frame) {
            // It never gets to here....
            console.log( "*** " + funk + ": connected!" );
        });
    }

And my WebSocketConfig.java file is the following:

import com.slimsimapps.ava.badlog.BadLogService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;
import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer;
import org.springframework.web.socket.server.standard.TomcatRequestUpgradeStrategy;
import org.springframework.web.socket.server.support.DefaultHandshakeHandler;

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {

    @Autowired
    BadLogService log;

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        log.a(config);
        config.enableSimpleBroker("/topic");
        config.setApplicationDestinationPrefixes("/app");
        log.o(config);
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        log.a(registry);

        //registry.addEndpoint("/gs-guide-websocket").withSockJS();

        registry.addEndpoint("/gs-guide-websocket")
                .setHandshakeHandler(new DefaultHandshakeHandler(new TomcatRequestUpgradeStrategy()))
                //.setAllowedOrigins( "slimsim.heliohost.org" )
                .setAllowedOrigins( "*" )
                .withSockJS();

        log.o(registry);
    }

}

Thanks so much for any help!

Hi

I managed to upload my war-file following your instruction, thank you!

I then preceded to make a few changes to the app, and they all work fin on my localhost. But when I deployed it said "Java deployment failed with errors. For further information please contact support" with a link to this forum. 

One of the changes i made was to add the following to my application.properties-file:

server.servlet.context-path=/ava-0.0.1-SNAPSHOT

But I changed it back and I still could not deploy the .war-file.

Now I am lost for ideas on what I might have done to make my app deployment fail. 

Is there any way you can help me, with logs or ideas? 

So, here is the info:

• Username: slimsim
• WAR-file: ava-0.0.1-SNAPSHOT.war
• Path: /home/slimsim/
• Server: johnny
• Time of deployment: 2020-10-16, 9:44 PM (according to the File Manager, so I'm guessing Swedish time and not server-time?) 

Thanks so much!

Hi

I'm trying to deploy a war-file created with Spring Boot, and I read these instructions (from 2017) https://www.helionet.org/index/topic/27458-how-to-deploy-war-on-heliohost/ where it said to create a topic here to "request for it to be deployed".

If this is not the current procedure I am sorry, the wiki-link in the instruction was broken, and I could not find any other instructions in the wiki.

So, here is the info:

• Username: slimsim
• WAR-file: ava-0.0.1-SNAPSHOT.war
• Path: /home/slimsim/
• Server: johnny

I have just received Java support and I would like to not loose it by not using it. I hope I still have time?

Now, if this war works, and it is deployed correctly, I have a fiew questions if that is all right:

• What URL will the web-app get?
• When I want to update the war, do I have to post here again or will it be automatic?
• And where / how can I see the logs from the Java code?
• And last question; is there any resent instructions for working with war's and spring boot?

Thanks so much for your support, I appreciate very much what you do and this service!

Best regards!
