Remote JDBC Connection to OpenEdge Database

Hi,

I am trying to connect my OpenEdge database remotely in my java application using JDBC. Using this knowledge base. But when I run the program I got this error:

java.sql.SQLNonTransientConnectionException: [DataDirect][OpenEdge JDBC Driver]Error establishing socket to host and port: ec2-54-147-132-36.compute-1.amazonaws.com:6786. Reason: Connection timed out: connect

	at java.sql.DriverManager.getConnection(DriverManager.java:664)
	at java.sql.DriverManager.getConnection(DriverManager.java:247)
	at JDBCConnection.main(JDBCConnection.java:15)

I think I have to enable remote access to my OpenEdge database but don't know how to do that.

I am new for Progress platform and openedge so please let me know if there any other configuration needed.

Thanks in advance.
