Erel are you able to reproduce it with my sources?

Erel · Jan 26, 2017

I wasn't able to reproduce it however I didn't try too much.

mindful · Jan 26, 2017

@billyrudi you could use :

B4X:

Public Sub RedirectOutput(Dir As String, FileName As String) 'ignore
#If RELEASE
   Dim out As OutputStream = File.OpenOutput(Dir, FileName, False) 'Set to True to append the logs
   Dim ps As JavaObject
   ps.InitializeNewInstance("java.io.PrintStream", Array(out, True, "utf8"))
   Dim jo As JavaObject
   jo.InitializeStatic("java.lang.System")
   jo.RunMethod("setOut", Array(ps))
   jo.RunMethod("setErr", Array(ps))
#End If
End Sub

Run it after srvr.Start like:

B4X:

RedirectOutput(File.DirApp, "logs.txt")

and it will create a logs.txt file where your jar is.

This code is provided by @alwaysbusy with the ABMaterial library.

Erel · Jan 26, 2017

I don't think that any code is required. He is currently running the project from the IDE in debug mode. He just need to switch to release mode.

billyrudi · Jan 30, 2017

Hi,
this is my log in runtime with the server error.
Erel can you help me to understand how to solve it?
regards Paolo

Erel · Jan 30, 2017

The error in these logs has nothing to do with the error you posted in the first post.

You are not closing the connection properly and eventually run out of SQL connections.

billzhan · Jan 30, 2017

You may have SSL certificate cache issue. If you are using SSL , https://yourdomain.com(say the real ip is 2.3.4.5), once you visit this site with the browser(Chrome on Windows), the certificate will be cached by the browser(the expire time is determined by your setting). After that if you use https://yourdomain.com:987 (port has been changed), the browser will send the cached certificate to the server. This will make the connection closed, and it seems that the server stop to work.

You can test by switching to another browser or use the http://2.3.4.5:987 (ip address instead of domain name), this exception should disappear.
