Java Database Connectivity (JDBC)

I am trying to establish DB2 connection via Java. I get the following error. I am using the Eclipse as IDE. I have attached the stack trace of the error message and also the java code I use to establish the DB2 Connection. Please advice.

I could succesfully connect to the same DB using external tool. I get this error only when i try to connect to DB using JDBC.

The term "Insufficient data" in the stack trace is misleading. I am not sure, what else information is required to establish connection.

I have following Jar Files in my class path.
· Common.jar
· db2dbgm.jar
· db2fs.jar
· db2jcc4.jar
· db2jcc.jar
· db2jcc_javax.jar
· db2jcc_license_cisuz.jar
· db2jcc_license_cu.jar
· db2policy.jar
· db2qgjava.jar
· db2umplugin.jar

Error Message stack trace:

com.ibm.db2.jcc.a.sm: [jcc][t4][2030][11211][3.51.90] A communication error occurred during operations on the connection's underlying socket, socket input stream,

Java Code I use for connection:

package com.sample;

public class LegacyTraceExample {
public static void main(String[] args) {
try {
// load driver
Class.forName("com.ibm.db2.jcc.DB2Driver");
// set connection properties
String databaseUrl = "jdbc:db2://HostName:PortNo/DataBaseName";
// get connection
java.sql.Connection con = java.sql.DriverManager.getConnection(
databaseUrl, "UserName", "Password");
// execute a query
java.sql.Statement stmt = con.createStatement();

String query = "SELECT COUNT(*) FROM TableName";
java.sql.ResultSet rs = stmt.executeQuery(query);

while (rs.next()) {
System.out.println("\n" + query + " = " + rs.getInt(1));
}

rs.close();
stmt.close();
con.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
