Possible solutions for a SQLNonTransientException

Question

I am very new to database connections with Java and am having a difficult time connecting to the database I was provided. So far I've learned that installing the correct DB2 drivers may have been an issue and putting them in the CLASSPATH for the program. I have done this and I still am not able to establish a connection. Please Help!

Here is a print out of my error report in Eclipse:

com.ibm.db2.jcc.am.SqlNonTransientConnectionException: [jcc][t4][10380][11951][4.13.127] Required property "URLname" is unknown host. ERRORCODE=-4222, SQLSTATE=08001 at com.ibm.db2.jcc.am.id.a(id.java:667) at com.ibm.db2.jcc.am.id.a(id.java:60) at com.ibm.db2.jcc.am.id.a(id.java:103) at com.ibm.db2.jcc.t4.a.(a.java:231) at com.ibm.db2.jcc.t4.b.a(b.java:1901) at com.ibm.db2.jcc.am.kb.a(kb.java:700) at com.ibm.db2.jcc.am.kb.(kb.java:653) at com.ibm.db2.jcc.t4.b.(b.java:332) at com.ibm.db2.jcc.DB2SimpleDataSource.getConnection(DB2SimpleDataSource.java:231) at com.ibm.db2.jcc.DB2SimpleDataSource.getConnection(DB2SimpleDataSource.java:197) at com.ibm.db2.jcc.DB2Driver.connect(DB2Driver.java:472) at com.ibm.db2.jcc.DB2Driver.connect(DB2Driver.java:113) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at ServerAcessDemo.main(ServerAcessDemo.java:23)

Here is the code I have developed so far:

import java.sql.*;

public class ServerAcessDemo{

    // jdbc driver name and database URL
    static final String JDBC_DRIVER = "com.ibm.db2.jcc.DB2Driver";
    static final String DB_URL = "jdbc:db2://URLname/portNumber";

    // Database credentials
    static final String USER = "userID";
    static final String PASSWORD = "password";

    public static void main(String[] args){

        Connection conn = null;
        try{
            // Register JDBC driver
            Class.forName(JDBC_DRIVER);

            // open a connection
            System.out.println("Connecting to a selected database...");
            conn = DriverManager.getConnection(DB_URL, USER, PASSWORD);
        }
        catch(Exception e){
            // handle errors for Class.forName
            e.printStackTrace();
        }
        finally{
            // finally block used to close resources
            try{
                if(conn!=null)
                    conn.close();
            }
            catch(SQLException se){
                se.printStackTrace();
            }//end finally try
        }//end try
    }
}

I am not sure if this is as simple as that, but you set:

static final String DB_URL = "jdbc:db2://URLname/portNumber";

and the error is Required property "URLname" is unknown host, so it seems that you have supplied wrong DB_URL value, it should be something like jdbc:db2://localhost:50000/your_database_name, assuming your DB runs locally on 50000 port, you need to provide right database name.
