Try putting the user and password into the properties. This is my code:

public void openConnection() throws SQLException { StringBuffer urlBuf = new StringBuffer();

urlBuf.append( "jdbc:mysql://" );

urlBuf.append( this.host ); if ( this.port != null ) { urlBuf.append( ":" ); urlBuf.append( this.port ); }

urlBuf.append( "/" ); urlBuf.append( this.database );

java.util.Properties info = new java.util.Properties();

if ( this.name != null ) { info.put( "user", this.name ); }

if ( this.pass != null ) { info.put( "password", this.pass ); }

this.openConnection( urlBuf.toString(), info ); }

private void openConnection( String url, Properties info ) throws SQLException { if ( this.isOpen() ) throw new SQLException ( "connection is already open" );

try { this.connection = DriverManager.getConnection( url, info ); this.isOpen = true; } catch ( SQLException ex ) { this.connection = null; throw ex; } }
