I have written a java program to connect to AS400 DB. I am using jt400-6.4.jar to connect to DB.
DB Properties I am using:
as400_dbUrl=jdbc:as400://host/schema;translate binary=true
as400_dbUser=user
as400_dbPassword=pass
My program is not able to connect to DB server i am getting the below error.
2017-06-30 05:36:53 ERROR DBUtil:88 - Exception:
java.sql.SQLException: The application requester cannot establish the connection. (A remote host refused an attempted connect operation.)

I googled about this, not able to find the exact reason.
I think jt400.jar will use 8471 as the port to connect to DB. Please correct me if I am wrong regarding this port.
I am not able to ping the host. ping host is not returning any response.
I am able to telnet like telnet host. But I am not able to telnet the system like telnet host 8471
Your hlep will be highly appreciable. Kindly help.
try updating your DB property as:
Add <:port-number> after host
as400_dbUrl=jdbc:as400://host:port/schema;translate binary=true
Hope this solves your problem.

I am trying to remote a debug an application which is deployed through Websphere. I have all the port configured correctly on server side and on eclipse side. I can use
telnet host port
to connect to remote host and port correctly. But When I try to connect through remote debug through eclipse, I run into the error
Failed to connect to remote VM
com.sun.jdi.connect.spi.ClosedConnectionException
What can be the possible causes for this? I have checked and searched Stackoverflow for this error already. I have tried the most things from answer on this question Eclipse Error: "Failed to connect to remote VM"
I changed the port and it worked. It was a networking issue with that port of 7777.
I start up sftp server using Apache Mina Sshd Api. please refer follow link to see more details about my local SFTP server.Link.
I tried to connect to that server from remotely by giving host name as my ip address but i couldn't enable to connect with the sftp server. I got "connection refused" error message.But i can connect locally.To connect locally i use winscp sftp client giving my host name as "localhost" but in remotely i can not give host name as localhost.So i gave host name as my machine IP address.When i gave that i got above error message.
So i would like to know that how can i connect with my local sftp server from remote machine.
Thank you.
Hi finally found out How to access Apache Mina sshd sftp server from remote machine. The problem was on my Apache Mina sshd sftp server set up.You can refer attached link to see my Apache Mina sshd sftp server details.
In there previously i set host as sshd.setHost("localhost"); instead of that i changed it into sshd.setHost(0.0.0.0);.So now you can access your local sftp server providing your machine ip address as a host name from remote machine.

And when I am trying to connect to the server using pgAdmin III, I am getting the following error "Server doesn't listen
The server doesn't accept connections: the connection library reports
could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432? ".
Please anyone help me regarding, Thanks in advance!!
Looks like your Postgresql daemon is not running. Check if the server has started and is running. I dont know which OS you are using but try ps -ax on linux/mac or the task manager in windows.
Maybe a firewall that is blocking the connection, you have to provide more information about your environment to be sure.
