Hi All, I have completed the NGINX and Websockets integration using WSO2 AS 5.3.0 Alpha. I have included the code in github at [1]. The websocket server implemented using JSR 356 and the jax-rs service are both deployed in the AS.
By using the curl client I am able to send and display messages in the browser. The *complete NGINX configuration* is as follows. Create a file named astest.com in /etc/nginx/sites-available. The content of astest.com should be as follows. *upstream wso2.as.com <http://wso2.as.com> { ip_hash;* * # WSO2 AS address is xx.xxx.xxx.xxx* * server xx.xxx.xxx.xxx:9763; keepalive 8;}# the nginx server instanceserver { listen 80; server_name as.wso2.com <http://as.wso2.com> ; access_log /var/log/nginx/nginxtest.log; location / { proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header X-NginX-Proxy true; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_pass http://wso2.as.com/ <http://wso2.as.com/>; proxy_redirect off; } }* Execute the following commands. *cd /etc/nginx/sites-enabledsudo ln -s /etc/nginx/sites-available/astest.com <http://astest.com> astest.com <http://astest.com>* The above creates a symbolic link of the nginx server instance in /etc/nginx/sites-enabled. In order for the NGINX server instance to take effect I also appended the following in the /etc/hosts file in my local machine. *# nginx virtual servers* *# Local machine ip is xx.xxx.xxx.xxx* *xx.xxx.xxx.xxx as.wso2.com <http://as.wso2.com>* Execute the following command. *source /etc/hosts* By using the curl client now we can successfully send and display messages to the browser using the following command where the url is of the following format "http://as.wso2.com:80/FirstJaxRsService/{message}";. Note that in order for the browser to accept messages first a connection needs to be opened. *curl http://as.wso2.com:80/FirstJaxRsService/hello <http://as.wso2.com:80/FirstJaxRsService/hello>* [1] https://github.com/SabraO/WebsocketNginxintegration Thanks and Regards.
