hye every one. i wrote a jdbc program and saved it as .java file from notepad in order to connect Db2. the code is as follows:

import java.sql.*;

public class jdbc {

public static void main( String arg[]) {

Connection c = null;
Statement st = null;
ResultSet rs;
String query = "CREATE TABLE book ( NAME VARCHAR(20),ID INTEGER,RATE INTEGER)";
String query1 = "INSERT INTO book VALUES ( 'HFSJ',1,100)";
String query2= "INSERT INTO book VALUES ( 'JSPCOOKBOOK',2,90)";


try {
Class.forName("com.ibm.db2.jcc.DB2Driver");
}

catch( Exception ex) {
System.out.println(ex.getMessage());
}

try {

c = DriverManager.getConnection("jdbc b2://localhost:50000/sample?UserID=pentium4&password=18may2003");
st = c.createStatement();
st.executeUpdate(query);
st.executeUpdate(query1);
st.executeUpdate(query2);
st.executeUpdate("INSERT INTO BOOK VALUES ( 'SCJP',1,200)");
rs= st.executeQuery("SELECT * FROM BOOK");

while(rs.next())
{
System.out.println(rs.getString("NAME")+" " +rs.getInt("ID")+" "+rs.getInt("MARKS"));
}


}

catch(SQLException e)
{
System.out.println(e.getMessage());
}

}
}


i got the error as "[ibm][db2][jcc][t4][10205][11234] Null userid is not supported."

but i have placed the jar files (C:\Program Files\IBM\SQLLIB\java\db2jcc_license_cu.jar;C:\Program Files\IBM\SQLLIB\java\db2jcc.jar) in classpath environmental system variables.
