JDBC Oracle connection in java

I have connection to Oracle database in ASP. Now, I have problem converting to the connection to use JDBC in java. Please help shed some light.

Oracle Connection in ASP
------------------------------
strConn ="DRIVER={Oracle in OraHome90};DSN=<DSN>;DBQ=<DBQ>;UID=<user name>;PWD=<password>;"
Set conntemp = Server.CreateObject("ADODB.Connection")
if conntemp.state=0 then
      conntemp.Open strConn

My attempt in JDBC
---------------------
String driver = "oracle.jdbc.driver.OracleDriver";
Class.forName(driver);

DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection con = DriverManager.getConnection("jdbc:oracle:thin:@(description=(address=(host=<host name>)(protocol=tcp)(port=<port>))(connect_data=(sid=<sid>)))",<user name>,<password>);

When i run the connection in java, i get IOException : The network adapter could not establish the connection.

Is it because i specify the host name wrongly?

thanks
