Hi all,

I am looking how to create a connection code to Mobile server without use file mobileserverid.dat  ?

E,g i have this code into my java API application

==============

private static Connection getConnection(String user ,String password)
{

Connection conn =null;

try
{

DriverManager.registerDriver((Driver)(Class.forName("oracle.jdbc.driver.OracleDriver").newInstance()));

}
catch(Exception e)
{
e.printStackTrace();
}
try
{

conn=null;
String jdbc_url = "jdbc:oracle:thin:@ + hostName + :" + DBPort + ":" + SID;
conn = DriverManager.getConnection(jdbc_url,user,password);

}
catch(Exception e)
{
e.printStackTrace();
}

return conn;
}
}

;
