Connection refused via JDBC

Question

I have another connection refused problem, seems to be common.
Looked at previous posts, answer(s) were not explicit.
Able to connect to db via SQL navigator.
What do I have to do?
my code:
try {
DriverManager.registerDriver (new
oracle.jdbc.driver.OracleDriver());
     DriverManager.getConnection      
     ("jdbc:oracle:thin:@192.168.0.3:1521:orcl", "scott", "tig
er");
     }catch ( SQLException sqle ) {
          out.println( "jdbc error: " + sqle );
error message:
jdbc error: java.sql.SQLException: Io exception: Connection
refused(DESCRIPTION=(TMP=)(VSNNUM=135294976)(ERR=12505)
(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))
listener log:
05-JUL-2001 09:30:32 * (CONNECT_DATA=(SID=orcl)(CID=(PROGRAM=)
(HOST=__jdbc__)(USER=oracle))) * (ADDRESS=(PROTOCOL=tcp)
(HOST=192.168.0.3)(PORT=1407)) * establish * orcl * 12505
TNS-12505: TNS:listener could not resolve SID given in connect
descriptor

Answer 1

Problem solved!
Helps to look at the tnsnames.ora file. All I had to do was use
the host name in the URL, because that's the way its spelled out
in tnsnames.ora
