Re: nginx + Tomcat 9

2018-07-16 Thread Giacomo Arru - BETA Technologies
Hi, I installed and configured HAProxy as a basic proxy but I'm facing the same 
issues with my application war: 

-when I upload a file > 60k the upload fails (hangs) 
-websocket stops working after 30 seconds 

Maybe I need to tweak tomcat?

You should go with HAProxy. I have used it in the infra of one of Payment 
Gateway.. 
It works really good. 
Let me know.. if I can help you in setting up HAProxy. 

Best,

Hi Simon, 

I only get oputput in logs with nginx debug, but it is way too much verbose and 
I can't determine why the connection times out. 

I get no useful messages in tomcat logs neither. 

I think I'll set up and HAProxy test environment and see how it works with my 
app and tomcat. 

I suspect I need the nginx+ payment options/support. I'm happy to pay but I've 
read about HAProxy vs nginx and it may be better fitting my needs; so it's 
worth the test.

I had a similar problem. I could resolved it by sending a keep alive 
message from the browser. 
If you still get disconnections (backend or middlerware could disconnect), 
you need some logic in the frontend to restart the connection. 
I didn't have to change any tomcat configuration, or the websocket code. 

You can test connecting direct to tomcat websocket (without nginx) to check 
where is the problem. 
You can also read these nginx configs: 
proxy_connect_timeout 
proxy_read_timeout 

Hope it helps,

I tried to enable debug logging for org.apache.tomcat.websocket but without 
success 

here is my logging.properties 



handlers = java.util.logging.ConsoleHandler 

.handlers = 1catalina.org.apache.juli.AsyncFileHandler, 
java.util.logging.ConsoleHandler 

java.util.logging.ConsoleHandler.level = ALL 
java.util.logging.ConsoleHandler.formatter = org.apache.juli.OneLineFormatter 

org.apache.coyote.http2.level = ALL 
org.apache.tomcat.websocket.level = ALL 
org.apache.coyote.http11.Http11AprProtocol = ALL

Turn on debug logging for the org.apache.tomcat.websocket package

nginx + Tomcat 9

2018-07-10 Thread Giacomo Arru - BETA Technologies
Hi, 
we are using nginx as proxy for our web app deployed in Tomcat 9. 

The app uses websocket. The websocket connection dies after 30/40 seconds and 
we can't figure out why. 

Any suggestions?
