Java connectivity to ORacle 816

[Sharma]

I installed on Oracle 816 on one of our server, our Java program which is working fine with ORacle 805 server doesn't work with Oracle 816.

I get this error.

java.sql.SQLException: No more data to read from socket
[DBConnection.class] Error! Could not establish connection.
java.lang.NullPointerException:

What may be probable cause of this error.

Is their any change I have to make to 816 server.

Thanks.

Are you using the updated 8.1.6 client and JDBC?

I am not sure what to answer your question Jeff.

I did new installation of Oracle 816, created the schema and trying to access the database.

I am using Oracle thin driver in Java Application

jdbc:oracle:thin:scott/tiger@112.11.16.18:1521:ORCL

Same works fine, if I change the IP address of server that has Oracle 805.
The error occurs in getconnection object.

con = DriverManager.getConnection("jdbc:oracle:thin:" .......)

Thanks.
