Hi,
I am learning to use the above components and I am using a sample servlet.
The code is as follows:

String url = "jdbc:db2://localhost:6789/tcasedb";

String userid = "db2admin";
String passwd = "db2admin";

String dbDriver = ("com.ibm.db2.jcc.DB2Driver");

Class.forName(dbDriver).newInstance();

con = DriverManager.getConnection(url, userid, passwd);

out.println("<H1>Employee Roster</H1>");
Statement stmt = con.createStatement();

--- I omitted not relevant code --------


As a result I get the following:
com.ibm.db2.jcc.b.DisconnectException: A communication error has been detected. Communication protocol being used: {0}. Communication API being used: {1}. Location where the error was detected: {2}. Communication function detecting the error: {3}. Protocol specific error codes(s) {4}, {5}, {6}.
